141-703: Typically, synthetic cannabinoids are sprayed onto plant matter and are usually smoked, although they have also been ingested as a concentrated liquid form in the United States and United Kingdom since 2016. They have been marketed as herbal incense, or "herbal smoking blends", and sold under common names like K2 , spice , and synthetic marijuana . They are often labeled "not for human consumption" for liability defense. A large and complex variety of synthetic cannabinoids are designed in an attempt to avoid legal restrictions on cannabis , making synthetic cannabinoids designer drugs . Most synthetic cannabinoids are agonists of

282-576: A chemical substance used in religious, shamanic , or spiritual contexts – in the Indian subcontinent since the Vedic period . The earliest known reports regarding the sacred status of cannabis in the Indian subcontinent come from the Atharva Veda , estimated to have been composed sometime around 1400 BCE. The Hindu god Shiva is described as a cannabis user, known as the "Lord of bhang ". In modern culture,

423-608: A laxative or enemas . Treatment of OIC is successional and dependent on severity. The first mode of treatment is non-pharmacological, and includes lifestyle modifications like increasing dietary fiber , fluid intake (around 1.5 L (51 US fl oz) per day), and physical activity . If non-pharmacological measures are ineffective, laxatives , including stool softeners ( e.g. , polyethylene glycol ), bulk-forming laxatives ( e.g. , fiber supplements ), stimulant laxatives ( e.g. , bisacodyl , senna ), and/or enemas , may be used. A common laxative regimen for OIC

564-466: A screening test in the field, but it cannot definitively confirm the presence of cannabis, as a large range of substances have been shown to give false positives. Researchers at John Jay College of Criminal Justice reported that dietary zinc supplements can mask the presence of THC and other drugs in urine. However, a 2013 study conducted by researchers at the University of Utah School of Medicine refute

705-451: A vaporizer , consuming THC in pill form, or consuming cannabis foods . There is concern that cannabis may contribute to cardiovascular disease, but as of 2018 , evidence of this relationship was unclear. Research in these events is complicated because cannabis is often used in conjunction with tobacco, and drugs such as alcohol and cocaine that are known to have cardiovascular risk factors. Smoking cannabis has also been shown to increase

846-492: A "marijuana-like-high" would follow his recipes and methods. Eicosanoid synthetic cannabinoids are analogs of endocannabinoids , such as anandamide . Endocannabinoids are cannabinoids naturally occurring in the body. One of the best known synthetic analogs of anandamide is methanandamide . The synthetic cannabinoids that have emerged recently have even greater structural diversity, possibly to subvert legal regulations on earlier generations of synthetic cannabinoids. There are

987-415: A causal relationship between cannabis use and chronic obstructive pulmonary disease . Short-term use of cannabis is associated with bronchodilation . Other side effects of cannabis use include cannabinoid hyperemesis syndrome (CHS), a condition which involves recurrent nausea, cramping abdominal pain, and vomiting. Cannabis smoke contains thousands of organic and inorganic chemical compounds. This tar

1128-932: A class of drugs that derive from, or mimic, natural substances found in the opium poppy plant. Opioids work in the brain to produce a variety of effects, including pain relief. As a class of substances, they act on opioid receptors to produce morphine -like effects. The terms 'opioid' and 'opiate' are sometimes used interchangeably, but there are key differences based on the manufacturing processes of these medications. Medically they are primarily used for pain relief , including anesthesia . Other medical uses include suppression of diarrhea , replacement therapy for opioid use disorder , reversing opioid overdose , and suppressing cough . Extremely potent opioids such as carfentanil are approved only for veterinary use. Opioids are also frequently used recreationally for their euphoric effects or to prevent withdrawal . Opioids can cause death and have been used for executions in

1269-641: A conclusion. Cannabis use is associated with increased risk of anxiety disorders, although causality has not been established. A review in 2019 found that research was insufficient to determine the safety and efficacy of using cannabis to treat schizophrenia, psychosis, or other mental disorders . Another found that cannabis during adolescence was associated with an increased risk of developing depression and suicidal behavior later in life, while finding no effect on anxiety. Heavy, long-term exposure to marijuana may have physical, mental, behavioral and social health consequences. It may be "associated with diseases of

1410-426: A decrease in short-term memory, dry mouth, impaired motor skills, reddening of the eyes, dizziness, feeling tired and vomiting. Some users may experience an episode of acute psychosis , which usually abates after six hours, but in rare instances, heavy users may find the symptoms continuing for many days. Legalization has increased the rates at which children are exposed to cannabis, particularly from edibles. While

1551-457: A derivative of HU-210 , is a hybrid cannabinoid because it has the dibenzopyran ring common of classical cannabinoids and an aliphatic hydroxyl group common in the CP family of nonclassical cannabinoids. Aminoalkylindoles are structurally dissimilar to THC and include naphthoylindoles ( JWH-018 ), phenylacetylindoles ( JWH-250 ), and benzoylindoles ( AM-2233 ). Aminoalkylindoles are considered to be

1692-438: A dibenzopyran ring. They were developed starting in the 1960s, following the isolation of THC, and were originally the only cannabinoids synthesized. Classical cannabinoids include nabilone and dronabinol , and one of the best known synthetic classical cannabinoids is HU-210 . HU-210 is a chiral compound first synthesized by Raphael Mechoulam at Hebrew University in the 1980s. It was discovered in herbal incense products by

1833-458: A drug use testing program or a forensic investigation of a traffic or other criminal offense. The concentrations obtained from such analyses can often be helpful in distinguishing active use from passive exposure, elapsed time since use, and extent or duration of use. These tests cannot, however, distinguish authorized cannabis smoking for medical purposes from unauthorized recreational smoking. Commercial cannabinoid immunoassays , often employed as

1974-611: A drug. Emergency room (ER) admissions associated with cannabis use rose significantly from 2012 to 2016; adolescents from age 12–17 had the highest risk. At one Colorado medical center following legalization, approximately two percent of ER admissions were classified as cannabis users. The symptoms of one quarter of these users were partially attributed to cannabis (a total of 2567 out of 449,031 patients); other drugs were sometimes involved. Of these cannabis admissions, one quarter were for acute psychiatric effects , primarily suicidal ideation , depression, and anxiety. An additional third of

2115-584: A family history of mental illness . Individuals with risk factors for psychotic disorders are often counseled against using synthetic cannabinoids. Psychiatrists have suggested that the lack of an antipsychotic chemical, like CBD in natural cannabis , may make synthetic cannabinoids more likely to induce psychosis than natural cannabis. There are five major categories for synthetic cannabinoids: classical cannabinoids, non-classical cannabinoids, hybrid cannabinoids, aminoalkylindoles , and eicosanoids . Classical cannabinoids are analogs of THC that are based on

2256-430: A few different structural classifications of synthetic cannabinoids that include many of the new structures, some of which are shown in table one. The indazole carboxamide group, including APINACA (AKB-48), an adamantyl indazole carboxamide, and AB-PINACA , an aminocarbonyl indazole carboxamide, is an example of a new group of synthetic cannabinoids. Most clandestine manufacturers and producers only make small changes to

2397-425: A height, and wandering into traffic; cardiovascular effects; and central nervous system depression . Researchers have pointed out a few ways that synthetic cannabinoids differ from marijuana, and therefore may be more dangerous. First, they often have greater intrinsic activity . Many of the synthetic cannabinoids are full agonists of the cannabinoids receptors , CB 1 and CB 2 , compared to THC , which

2538-472: A limited number of territories, including Canada, Belgium , Australia, the Netherlands , New Zealand, Spain, and many U.S. states . This usage generally requires a prescription, and distribution is usually done within a framework defined by local laws. According to DEA Chief Administrative Law Judge, Francis Young, "cannabis is one of the safest therapeutically active substances known to man". Being under

2679-523: A longer period of abstinence was associated with smaller magnitudes of impairment, both retrospective and prospective memory were impaired in cannabis users. The authors concluded that some, but not all, of the deficits associated with cannabis use were reversible. A 2012 meta-analysis found that deficits in most domains of cognition persisted beyond the acute period of intoxication, but was not evident in studies where subjects were abstinent for more than 25 days. Few high quality studies have been performed on

2820-791: A non-oral route ( e.g. subcutaneous for metoclopramide, rectally for domperidone). Evidence suggests that opioid-inclusive anaesthesia is associated with postoperative nausea and vomiting. Patients with chronic pain using opioids had small improvements in pain and physically functioning and increased risk of vomiting. Tolerance to drowsiness usually develops over 5–7 days, but if troublesome, switching to an alternative opioid often helps. Certain opioids such as fentanyl , morphine and diamorphine (heroin) tend to be particularly sedating, while others such as oxycodone , tilidine and meperidine (pethidine) tend to produce comparatively less sedation, but individual patients responses can vary markedly and some degree of trial and error may be needed to find

2961-429: A range of 1.1–1.5 ng/mL of 5F-PB-22 . Three of the four cases were sudden episodes and the symptoms leading to death included acute shortness of breath; vasocongestion in the liver, spleen, and kidneys; bilateral pulmonary edema ; dead inflamed tissue (necrotizing granulomatous inflammation); and congestion of most internal organs. The fourth case presented to the hospital with severe problems that deteriorated over

3102-472: A record 44% of the US population has tried marijuana in their lifetime, an increase from 38% in 2013 and 33% in 1985. Marijuana use in the United States is three times above the global average, but in line with other Western democracies. Forty-four percent of American 12th graders have tried the drug at least once, and the typical age of first-use is 16, similar to the typical age of first-use for alcohol but lower than

3243-495: A strong compulsion to re-dose, withdrawal symptoms , and persistent cravings. There have been several deaths linked to synthetic cannabinoids. The Centers for Disease Control and Prevention (CDC) found that the number of deaths from synthetic cannabinoid use tripled between 2014 and 2015. In 2018, the United States Food and Drug Administration warned of significant health risks from synthetic cannabinoid products that contain

3384-475: A successful long-term care strategy for those with chronic cancer pain . Just over half of all states in the US have enacted laws that restrict the prescribing or dispensing of opioids for acute pain. Guidelines have suggested that the risk of opioids is likely greater than their benefits when used for most non-cancer chronic conditions including headaches , back pain , and fibromyalgia . Thus they should be used cautiously in chronic non-cancer pain. If used

3525-420: A suitable replacement for the naphthoyl moiety that is currently regulated by US scheduling laws . Although most synthetic cannabinoids are not direct analogs of THC, they share many common features with THC. Most are lipid-soluble , non-polar , small molecules (usually 20–26 carbon atoms) that are fairly volatile , making them "smokable", like THC. Another common feature of most synthetic cannabinoids and THC

3666-508: A synergistic pain relieving effect permitting smaller doses of opioids be used. Consequently, several opioid/antihistamine combination products have been marketed, such as Meprozine ( meperidine / promethazine ) and Diconal ( dipipanone / cyclizine ), and these may also reduce opioid induced nausea. Opioid-induced constipation (OIC) develops in 90 to 95% of people taking opioids long-term. Since tolerance to this problem does not generally develop, most people on long-term opioids need to take

3807-836: A synthetic cannabinoid, either AMB-FUBINACA or AB, in Christchurch over two days. Some of the people were in critical condition in the Intensive Care Unit . On October 20, 2011, the Louisiana State University football program announced that it had suspended three players, including star cornerback Tyrann Mathieu , who tested positive for synthetic cannabinoids. On July 12, 2016, 33 people were intoxicated by an herbal "incense" product called "AK-47 24 Karat Gold", and dozens overdosed , in Brooklyn . Eighteen people were transported to local hospitals. The herbal "incense" product

3948-515: A variety of other designer drugs, has been illegal. Cannabis (drug) Cannabis ( / ˈ k æ n ə b ɪ s / ), commonly known as marijuana ( / ˌ m æ r ə ˈ w ɑː n ə / ), weed , and pot , among other names , is a non-chemically uniform drug from the cannabis plant. Native to Central or South Asia, the cannabis plant has been used as a drug for both recreational and entheogenic purposes and in various traditional medicines for centuries. Tetrahydrocannabinol (THC)

4089-467: A wide array of plants. However, oftentimes, none of the listed ingredients have been detectable. Herbal components of 'Spice' (a non-exhaustive list): Many of the early synthetic cannabinoids that were synthesized for use in research were named after either the scientist who first synthesized them or the institution or company where they originated. Some of the names of synthetic cannabinoids synthesized for recreational use were given names to help market

4230-697: Is a NMDA receptor antagonist and is largely inactive as a cannabinoid . On the other hand, aminoalkylindoles , eicosanoids , and the other new synthetic cannabinoid groups typically do not have an asymmetric center, so they are usually not stereospecific. Recently there has been an increase in the emergence of terminally fluorinated synthetic cannabinoids, such as 5F-PB-22 (fluorinated version of PB-22 ) and XLR-11 (fluorinated version of UR-144 ). South Korea's National Forensic Service reported that 90% of all seized synthetic cannabinoids in 2013 were fluorinated, compared to no fluorinated synthetic cannabinoids reported in 2010. 5F-derivations (terminal fluorination) of

4371-495: Is a peripherally selective opioid available without a prescription used to suppress diarrhea. The ability to suppress diarrhea also produces constipation when opioids are used beyond several weeks. Naloxegol , a peripherally-selective opioid antagonist is now available to treat opioid induced constipation. Opioids may help with shortness of breath particularly in advanced diseases such as cancer and COPD among others. However, findings from two recent systematic reviews of

4512-508: Is a process characterized by neuroadaptations that result in reduced drug effects. While receptor upregulation may often play an important role other mechanisms are also known. Tolerance is more pronounced for some effects than for others; tolerance occurs slowly to the effects on mood, itching, urinary retention, and respiratory depression, but occurs more quickly to the analgesia and other physical side effects. However, tolerance does not develop to constipation or miosis (the constriction of

4653-422: Is a side-chain of five to nine saturated carbon atoms. It has been found that this chain of carbons is required for optimal psychotropic activity from binding CB 1 receptors . Also, most synthetic cannabinoids are agonists of both cannabinoid receptors , CB 1 and CB 2 , like THC; however, they often have greater binding affinity and therefore greater potency than THC, as seen in table two. Due to

4794-457: Is associated with cumulative cannabis exposure, and is reversed after one month of abstinence. There is limited evidence that chronic cannabis use can reduce levels of glutamate metabolites in the human brain. About 9% of those who experiment with marijuana eventually become dependent according to DSM-IV (1994) criteria. A 2013 review estimates daily use is associated with a 10–20% rate of dependence. The highest risk of cannabis dependence

4935-526: Is associated with heavy cannabis use, although the relationship is inconsistent and weaker than for tobacco and other substances. The direction of cause and effect , however, is unclear. The long-term effects of cannabis are not clear. There are concerns surrounding memory and cognition problems , risk of addiction, and the risk of schizophrenia in young people. Although global abnormalities in white matter and grey matter are not consistently associated with cannabis use, reduced hippocampal volume

5076-539: Is associated with increased adverse effects such as "sedation, nausea, vomiting, constipation, urinary retention, and falls". As a result, older adults taking opioids are at greater risk for injury. Opioids do not cause any specific organ toxicity, unlike many other drugs, such as aspirin and paracetamol. They are not associated with upper gastrointestinal bleeding and kidney toxicity . Prescription of opioids for acute low back pain and management of osteoarthritis seem to have long-term adverse effects According to

5217-442: Is better treated with medications other than opioids. Paracetamol and nonsteroidal anti-inflammatory drugs including ibuprofen and naproxen are considered safer alternatives. They are frequently used combined with opioids, such as paracetamol combined with oxycodone ( Percocet ) and ibuprofen combined with hydrocodone ( Vicoprofen ), which boosts the pain relief but is also intended to deter recreational use. Codeine

5358-528: Is by far the most widely used illicit substance, with the highest use among adults (as of 2018 ) in Zambia , the United States , Canada , and Nigeria . Between 1973 and 1978, eleven states decriminalized marijuana. In 2001, Nevada reduced marijuana possession to a misdemeanor and since 2012, several other states have decriminalized and even legalized marijuana. In 2018, surveys indicated that almost half of

5499-459: Is chemically similar to that found in tobacco smoke, and over fifty known carcinogens have been identified in cannabis smoke, including; nitrosamines, reactive aldehydes, and polycyclic aromatic hydrocarbons , including benz[a]pyrene. Cannabis smoke is also inhaled more deeply than tobacco smoke. As of 2015 , there is no consensus regarding whether cannabis smoking is associated with an increased risk of cancer. Light and moderate use of cannabis

5640-487: Is closely related to the same mechanism as tolerance. While there is anecdotal claims of benefit with ibogaine , data to support its use in substance dependence is poor. Critical patients who received regular doses of opioids experience iatrogenic withdrawal as a frequent syndrome. Drug addiction is a complex set of behaviors typically associated with misuse of certain drugs, developing over time and with higher drug dosages. Addiction includes psychological compulsion, to

5781-436: Is consistently found. Amygdala abnormalities are sometimes reported, although findings are inconsistent. Cannabis use is associated with increased recruitment of task-related areas, such as the dorsolateral prefrontal cortex , which is thought to reflect compensatory activity due to reduced processing efficiency. Cannabis use is also associated with downregulation of CB 1 receptors. The magnitude of down regulation

Synthetic cannabinoids - Misplaced Pages Continue

5922-467: Is controversial and, according to Lewis Nelson, a medical toxicologist at the NYU School of Medicine, a mistake. Nelson claims that relative to marijuana , products containing synthetic cannabinoids "are really quite different, and the effects are much more unpredictable. It's dangerous". Since the term synthetic does not apply to the plant, but rather to the cannabinoid that the plant contains ( THC ),

6063-428: Is due to gastric stasis (large volume vomiting, brief nausea relieved by vomiting, oesophageal reflux, epigastric fullness, early satiation), besides direct action on the chemoreceptor trigger zone of the area postrema , the vomiting centre of the brain. Vomiting can thus be prevented by prokinetic agents ( e.g. domperidone or metoclopramide ). If vomiting has already started, these drugs need to be administered by

6204-408: Is felt within minutes when smoked, but may take up to 90 minutes when eaten (as orally consumed drugs must be digested and absorbed). The effects last for two to six hours, depending on the amount used. At high doses, mental effects can include anxiety , delusions (including ideas of reference ), hallucinations , panic , paranoia , and psychosis . There is a strong relation between cannabis use and

6345-447: Is formally known as acute cannabis-associated psychotic symptoms (CAPS). At an epidemiological level, a dose–response relationship exists between cannabis use and increased risk of psychosis and earlier onset of psychosis. Although the epidemiological association is robust, evidence to prove a causal relationship is lacking. Cannabis may also increase the risk of depression, but insufficient research has been performed to draw

6486-641: Is found in those with a history of poor academic achievement, deviant behavior in childhood and adolescence, rebelliousness, poor parental relationships, or a parental history of drug and alcohol problems. Of daily users, about 50% experience withdrawal upon cessation of use (i.e. are dependent), characterized by sleep problems, irritability, dysphoria, and craving. Cannabis withdrawal is less severe than withdrawal from alcohol. According to DSM-V criteria, 9% of those who are exposed to cannabis develop cannabis use disorder, compared to 20% for cocaine , 23% for alcohol and 68% for nicotine . Cannabis use disorder in

6627-485: Is generally discouraged where that is the case. The weak opioid codeine , in low doses and combined with one or more other drugs, is commonly available in prescription medicines and without a prescription to treat mild pain. Other opioids are usually reserved for the relief of moderate to severe pain. Opioids are effective for the treatment of acute pain (such as pain following surgery). For immediate relief of moderate to severe acute pain, opioids are frequently

6768-404: Is insufficient for drawing conclusions about safety or efficacy. There is evidence supporting the use of cannabis or its derivatives in the treatment of chemotherapy-induced nausea and vomiting, neuropathic pain, and multiple sclerosis. Lower levels of evidence support its use for AIDS wasting syndrome , epilepsy, rheumatoid arthritis, and glaucoma. The medical use of cannabis is legal only in

6909-527: Is legalized only in the Australian Capital Territory . Cannabis is a Scythian word. The ancient Greeks learned of the use of cannabis by observing Scythian funerals, during which cannabis was consumed. In Akkadian , cannabis was known as qunubu ( 𐎯𐎫𐎠𐎭𐏂 ). The word was adopted in to the Hebrew as qaneh bosem ( קָנֶה בֹּשׂם ). Medical cannabis, or medical marijuana, refers to

7050-469: Is most often used for confirmation and quantitation. There are commercially available EMIT kits for the screening of the synthetic cannabinoids JWH-018 , JWH-073 , JWH-398 , JWH-200 , JWH-019 , JWH-122 , JWH-081 , JWH-250 , JWH-203 , CP-47,497 , CP-47,497-C8 , HU-210 , HU-211 , AM-2201 , AM-694 , RCS-4 , and RCS-8 through companies like NMS Labs, Cayman Chemical, and Immunoanalysis Corporation. In September 2018, at least 10 people overdosed on

7191-409: Is mostly used recreationally or as a medicinal drug, although it may also be used for spiritual purposes. In 2013, between 128 and 232 million people used cannabis (2.7% to 4.9% of the global population between the ages of 15 and 65). It is the most commonly used largely-illegal drug in the world, with the highest use among adults in Zambia , the United States , Canada , and Nigeria . Since the 1970s,

7332-585: Is not believed to increase risk of lung or upper airway cancer. Evidence for causing these cancers is mixed concerning heavy, long-term use. In general there are far lower risks of pulmonary complications for regular cannabis smokers when compared with those of tobacco. A 2015 review found an association between cannabis use and the development of testicular germ cell tumors (TGCTs), particularly non- seminoma TGCTs. Another 2015 meta-analysis found no association between lifetime cannabis use and risk of head or neck cancer. Combustion products are not present when using

7473-501: Is now rarely used. A related drug, prochlorperazine is more often used, although it has similar risks. Stronger antiemetics such as ondansetron or tropisetron are sometimes used when nausea is severe or continuous and disturbing, despite their greater cost. A less expensive alternative is dopamine antagonists such as domperidone and metoclopramide. Domperidone does not cross the blood–brain barrier and produce adverse central antidopaminergic effects, but blocks opioid emetic action in

7614-449: Is only a partial agonist . Secondly, they may have other actions in the body, in addition to activating cannabinoid receptors. Some may work on NMDA glutamate receptors. Some may also work on serotonin , either indirectly by inhibiting MAO and increasing 5-HT 1A expression , or by directly binding to serotonin receptors, including the 5-HT 1A and 5-HT 3 subtypes; some researchers speculate that this activity may be because

7755-501: Is properly limited to the natural alkaloids found in the resin of the opium poppy although some include semi-synthetic derivatives. Narcotic , derived from words meaning 'numbness' or 'sleep', as an American legal term, refers to cocaine and opioids, and their source materials; it is also loosely applied to any illegal or controlled psychoactive drug. In some jurisdictions all controlled drugs are legally classified as narcotics . The term can have pejorative connotations and its use

7896-565: Is the main psychoactive component of cannabis, which is one of the 483 known compounds in the plant, including at least 65 other cannabinoids , such as cannabidiol (CBD). Cannabis can be used by smoking , vaporizing , within food , or as an extract . Cannabis has various mental and physical effects , which include euphoria , altered states of mind and sense of time , difficulty concentrating, impaired short-term memory , impaired body movement (balance and fine psychomotor control), relaxation, and an increase in appetite . Onset of effects

8037-412: Is uncertain. Opioids are contraindicated as a first-line treatment for headache because they impair alertness, bring risk of dependence, and increase the risk that episodic headaches will become chronic. Opioids can also cause heightened sensitivity to headache pain. When other treatments fail or are unavailable, opioids may be appropriate for treating headache if the patient can be monitored to prevent

8178-468: The U.S. Customs and Border Protection in January 2009; however, classical cannabinoids are not often seen in synthetic cannabinoid blends for recreational use , likely because they are difficult to synthesize. Non-classical cannabinoids include cyclohexylphenols (CP), which were first synthesized in the late 1970s to 1980s by Pfizer as potential analgesics . The C8 homologue of CP-47,497 ( CP-47,497-C8 )

8319-453: The USCDC , methadone was involved in 31% of opioid related deaths in the US between 1999–2010 and 40% as the sole drug involved, far higher than other opioids. Studies of long term opioids have found that many stop them, and that minor side effects were common. Addiction occurred in about 0.3%. In the United States in 2016 opioid overdose resulted in the death of 1.7 in 10,000 people. Tolerance

8460-654: The Wisconsin Department of Health Services confirmed 16 more cases, bringing the total number of people affected by the outbreak in Wisconsin to 80 people since March 2018, including one death in July 2018. In August 2018, there were almost one hundred overdose cases reported over two days in New Haven, Connecticut from a bad batch of K2. The synthetic cannabinoid was believed to have been mixed with fentanyl , although no fentanyl

8601-568: The cannabinoid receptors . They have been designed to be similar to THC , the natural cannabinoid with the strongest binding affinity to the CB 1 receptor , which is linked to the psychoactive effects or "high" of marijuana . These synthetic analogs often have greater binding affinity and greater potency to the CB 1 receptors. There are several synthetic cannabinoid families (e.g., AM- xxx , CP- xx,xxx , HU- xx , JWH- xxx ) which are classified by

SECTION 60

#1732891570610

8742-425: The central and peripheral nervous system and the gastrointestinal tract . These receptors mediate both the psychoactive and the somatic effects of opioids. Opioid drugs include partial agonists , like the anti-diarrhea drug loperamide and antagonists like naloxegol for opioid-induced constipation, which do not cross the blood–brain barrier , but can displace other opioids from binding to those receptors in

8883-546: The chemoreceptor trigger zone . This drug is not available in the U.S. Some antihistamines with anticholinergic properties (e.g. orphenadrine , diphenhydramine ) may also be effective. The first-generation antihistamine hydroxyzine is very commonly used, with the added advantages of not causing movement disorders, and also possessing analgesic-sparing properties. Δ - tetrahydrocannabinol relieves nausea and vomiting; it also produces analgesia that may allow lower doses of opioids with reduced nausea and vomiting. Vomiting

9024-466: The endocannabinoids that activate them in the body. Synthetic cannabinoids were needed partly due to legal restrictions on natural cannabinoids, which make them difficult to obtain for research. Many have been useful because they bind selectively to either the CB1 or CB2 receptors, whereas THC has a similar affinity for both. Tritium -labelled cannabinoids such as CP-55,940 were instrumental in discovering

9165-424: The indole moiety that some synthetic cannabinoids possess is similar to the structure of serotonin. Third, synthetic cannabinoids may break down into metabolites, or create other by-products when heated, that may differ from marijuana. Phase 1 metabolism of JWH-018 results in at least nine monohydroxylated metabolites , three of which have been shown to be full agonists of the CB 1 receptors , compared to

9306-419: The metabolism of THC , which only results in one psychoactive monohydroxylated metabolite. The metabolite N-(3-hydroxypentyl) JWH-018 was found to have toxic effects that its parent compound does not. Some metabolites even appear to be cannabinoid antagonists . Lastly, they may contain unwanted substances, be mislabeled, or contain different doses than advertised (in one analysis, a difference of one log unit

9447-1093: The myenteric plexus . Because opioids are addictive and may result in fatal overdose, most are controlled substances . In 2013, between 28 and 38 million people used opioids illicitly (0.6% to 0.8% of the global population between the ages of 15 and 65). In 2011, an estimated 4 million people in the United States used opioids recreationally or were dependent on them. As of 2015, increased rates of recreational use and addiction are attributed to over-prescription of opioid medications and inexpensive illicit heroin . Conversely, fears about overprescribing, exaggerated side effects, and addiction from opioids are similarly blamed for under-treatment of pain. Opioids include opiates , an older term that refers to such drugs derived from opium , including morphine itself. Other opioids are semi-synthetic and synthetic drugs such as hydrocodone , oxycodone , and fentanyl ; antagonist drugs such as naloxone ; and endogenous peptides such as endorphins . The terms opiate and narcotic are sometimes encountered as synonyms for opioid. Opiate

9588-415: The μ- and δ-opioid receptors . THC also potentiates the effects of the glycine receptors . It is unknown if or how these actions contribute to the effects of cannabis. The high lipid-solubility of cannabinoids results in their persisting in the body for long periods of time. Even after a single administration of THC, detectable levels of THC can be found in the body for weeks or longer (depending on

9729-555: The "synthetic cannabinoids" but as a "synthetic phytocannabinoid". In the early 2000s, synthetic cannabinoids began to be used for recreational drug use in an attempt to get similar effects to cannabis . Because synthetic cannabinoid molecular structures differ from THC and other illegal cannabinoids, synthetic cannabinoids were not technically illegal. Since the discovery of the use of synthetic cannabinoids for recreational use in 2008, some synthetic cannabinoids have been made illegal , but new analogs are continually synthesized to avoid

9870-407: The 1–10 μg/L range during the first few hours after recreational usage and the metabolites are usually present in urine at similar concentrations. Little to no parent drug is present in urine, so there is a lot of research to try and identify the major urinary metabolites that could be used as markers of synthetic cannabinoid intake. The major urinary metabolites in most cases are formed by oxidation of

10011-455: The 20th century. In 2013, Uruguay became the first country to legalize recreational use of cannabis. Other countries to do so are Canada, Georgia , Germany , Luxembourg , Malta , South Africa , and Thailand . In the U.S., the recreational use of cannabis is legalized in 24 states , 3 territories, and the District of Columbia , though the drug remains federally illegal . In Australia , it

10152-462: The CB 2 receptor is found primarily in peripheral tissues, but is also expressed in neuroglial cells. THC appears to alter mood and cognition through its agonist actions on the CB 1 receptors, which inhibit a secondary messenger system ( adenylate cyclase ) in a dose-dependent manner. Via CB 1 receptor activation, THC indirectly increases dopamine release and produces psychotropic effects. CBD also acts as an allosteric modulator of

10293-489: The DSM-V involves a combination of DSM-IV criteria for cannabis abuse and dependence, plus the addition of craving, without the criterion related to legal troubles. From a clinical perspective, two significant school of thought exists for psychiatric conditions associated with cannabis (or cannabinoids) use: transient, non-persistent psychotic reactions, and longer-lasting, persistent disorders that resemble schizophrenia. The former

10434-873: The US that caused coagulopathy (prolonged or excessive bleeding) and resulted in the treatment of over 300 people and at least eight deaths. One of the most common non-cannabinoid ingredients in these products is oleamide , a fatty acid derivative that acts similarly to a cannabinoid and has hypnotic properties. Analysis of 44 products synthetic cannabinoid revealed oleamide in 7 of the products tested. Other non-cannabinoid ingredients that have been found in synthetic cannabinoid blends include harmine and harmaline , reversible monoamine oxidase inhibitors , which have been found with myristicin and asarone ; substituted cathinone derived stimulant drugs such as 4-methylbuphedrone and 4'-methyl-alpha-PPP ; and psychedelic tryptamine derivatives such as 4-HO-DET . Packages of synthetic cannabinoid products can claim to contain

10575-716: The United States . Side effects of opioids may include itchiness , sedation , nausea , respiratory depression , constipation , and euphoria . Long-term use can cause tolerance , meaning that increased doses are required to achieve the same effect, and physical dependence , meaning that abruptly discontinuing the drug leads to unpleasant withdrawal symptoms. The euphoria attracts recreational use, and frequent, escalating recreational use of opioids typically results in addiction. An overdose or concurrent use with other depressant drugs like benzodiazepines commonly results in death from respiratory depression . Opioids act by binding to opioid receptors, which are found principally in

10716-585: The United States advising of 89 confirmed cases of "serious unexplained bleeding" in Illinois. The cases are still being studied; however, 63 of the patients reported synthetic cannabinoid use, and laboratory analysis confirmed brodifacoum was present in at least 18 patients. As of April 24, 2018, 153 cases, including four deaths, linked to this outbreak have been reported to the Illinois Department of Public Health (IDPH) since March 7, 2018. On September 18, 2018,

10857-610: The alkyl side-chain to an alcohol and carboxylic acid followed by glucuronide conjugation and also by N-dealkylation and aromatic hydroxylation. For example, the main metabolites of JWH-018 , of which there are over 20, include carboxylated, monohydroxylated, dihydroxylated, and trihydroxylated metabolites, but they are mostly excreted in urine as glucuronide conjugates. The presence of synthetic cannabinoids or their metabolites in bodily fluids may be determined using specifically targeted commercially available immunoassay screening methods (EMIT), while liquid chromatography-mass spectrometry

10998-423: The amount administered and the sensitivity of the assessment method). Investigators have suggested that this is an important factor in marijuana's effects, perhaps because cannabinoids may accumulate in the body, particularly in the lipid membranes of neurons. The main psychoactive component of cannabis is tetrahydrocannabinol (THC), which is formed via decarboxylation of tetrahydrocannabinolic acid (THCA) from

11139-406: The application of heat. Raw leaf is not psychoactive because the cannabinoids are in the form of carboxylic acids . THC is one of the 483 known compounds in the plant, including at least 65 other cannabinoids, such as cannabidiol (CBD). THC and its major (inactive) metabolite, THC-COOH , can be measured in blood, urine, hair, oral fluid or sweat using chromatographic techniques as part of

11280-475: The benefits and harms should be reassessed at least every three months. In treating chronic pain, opioids are an option to be tried after other less risky pain relievers have been considered, including paracetamol or NSAIDs like ibuprofen or naproxen . Some types of chronic pain, including the pain caused by fibromyalgia or migraine , are preferentially treated with drugs other than opioids. The efficacy of using opioids to lessen chronic neuropathic pain

11421-574: The brand name Spice, were first released in 2005 by the now-dormant company the Psyche Deli in London. In 2006, the brand gained popularity. According to the Financial Times , the assets of the Psyche Deli rose from £65,000 in 2006 to £899,000 in 2007. The EMCDDA reported in 2009 that Spice products were identified in 21 of the 30 participating countries. Because of these controversies, and in particular

11562-404: The cannabinoid receptors in the early 1990s. Some early synthetic cannabinoids were also used clinically. Nabilone , a first generation synthetic THC analog, has been used as an antiemetic to combat vomiting and nausea since 1981. Synthetic THC (marinol, dronabinol ) has been used as an antiemetic since 1985, and an appetite stimulant since 1991, although synthetic THC is often not listed among

11703-473: The cases were for gastrointestinal issues including cannabinoid hyperemesis syndrome . According to the United States Department of Health and Human Services, there were 455,000 emergency room visits associated with cannabis use in 2011. These statistics include visits in which the patient was treated for a condition induced by or related to recent cannabis use. The drug use must be "implicated" in

11844-486: The combination of O -desmethyltramadol , a μ- opioid agonist and analgesic drug, and kratom , an Asiatic medicinal plant containing mitragynine , another μ- opioid agonist , in a synthetic cannabinoid product called "Krypton". And in 2013, AH-7921 was detected in smoking blends in Japan. In 2018, there was an outbreak of synthetic cannabinoids contaminated with anticoagulants , mainly brodifacoum , in at least 11 states in

11985-703: The course of a day, ending with circulatory , respiratory , central nervous system , and renal failure . There have been reports of a strong compulsion to re-dose, withdrawal symptoms , and persistent cravings lasting up to a week after taking synthetic cannabinoids, indicating that synthetic cannabinoids may be more addictive than marijuana . Studies have strongly linked particular synthetic cannabinoids with psychosis . The use of synthetic cannabinoids can be associated with psychosis and physicians are beginning to investigate if some patients with inexplicable psychotic symptoms may have at one point used synthetic cannabinoids. In contrast to most other recreational drugs ,

12126-692: The creator of the substance (e.g., JWH stands for John W. Huffman ), which can include several substances with different base structures such as classical cannabinoids and unrelated naphthoylindoles. Synthetic marijuana compounds began to be manufactured and sold in the early 2000s. From 2008 to 2014, 142 synthetic cannabinoid receptor agonists were reported to the European Monitoring-Center for Drugs and Drug Addiction (EMCDDA). Reported user negative effects include palpitations , paranoia , intense anxiety , nausea , vomiting, confusion, poor coordination, and seizures. There have also been reports of

12267-529: The development of chronic headache. Opioids are being used more frequently in the management of non-malignant chronic pain . This practice has now led to a new and growing problem with addiction and misuse of opioids. Because of various negative effects the use of opioids for long-term management of chronic pain is not indicated unless other less risky pain relievers have been found ineffective. Chronic pain which occurs only periodically, such as that from nerve pain , migraines , and fibromyalgia , frequently

12408-491: The difficulty of distinguishing natural cannabinoids obtained in laboratory (for example, CBD or synthetic THC ) from artificial novel synthetic cannabinoid analog compounds not present in nature (like nabilone, Spice, the HU, JWH series, etc.), the term "neocannabinoid" has been proposed to name the latter. Synthetic cannabinoids were made for cannabinoid research focusing on tetrahydrocannabinol (THC), cannabinoid receptors , and

12549-513: The dose is reduced abruptly or, specifically in the case of opioids, when an antagonist ( e.g. , naloxone ) or an agonist-antagonist ( e.g. , pentazocine ) is administered. Physical dependence is a normal and expected aspect of certain medications and does not necessarily imply that the patient is addicted. The withdrawal symptoms for opiates may include severe dysphoria , craving for another opiate dose, irritability, sweating , nausea , rhinorrea , tremor , vomiting and myalgia . Slowly reducing

12690-456: The dramatic psychotic state induced by use of synthetic cannabinoids has been reported, in multiple cases, to persist for several weeks, and in one case for seven months, after complete cessation of drug use. Some studies suggest that not only can synthetic cannabinoids induce psychosis, but they can worsen previously stable psychotic disorders and might trigger a chronic (long-term) psychotic disorder among vulnerable individuals such as those with

12831-423: The effects of cannabis is usually referred to as being "high". Cannabis consumption has both psychoactive and physiological effects. The "high" experience can vary widely, based (among other things) on the user's prior experience with cannabis, and the type of cannabis consumed. When smoking cannabis, a euphoriant effect can occur within minutes of smoking. Aside from a subjective change in perception and mood,

12972-547: The efficacy and safety of these types of preparations. Further tamper resistant medications are currently under consideration with trials for market approval by the FDA. The amount of evidence available only permits making a weak conclusion, but it suggests that a physician properly managing opioid use in patients with no history of substance use disorder can give long-term pain relief with little risk of developing addiction, or other serious side effects. Problems with opioids include

13113-418: The emergency department visit, but does not need to be the direct cause of the visit. Most of the illicit drug emergency room visits involved multiple drugs. In 129,000 cases, cannabis was the only implicated drug. THC is a weak partial agonist at CB 1 receptors , while CBD is a CB 1 receptor antagonist. The CB 1 receptor is found primarily in the brain as well as in some peripheral tissues, and

13254-417: The extent that the affected person persists in actions leading to dangerous or unhealthy outcomes. Opioid addiction includes insufflation or injection, rather than taking opioids orally as prescribed for medical reasons. In European nations such as Austria, Bulgaria, and Slovakia, slow-release oral morphine formulations are used in opiate substitution therapy (OST) for patients who do not well tolerate

13395-404: The first-use age for other illicit drugs. A 2022 Gallup poll concluded Americans are smoking more marijuana than cigarettes for the first time. Acute negative effects may include anxiety and panic, impaired attention and memory, an increased risk of psychotic symptoms, the inability to think clearly, and an increased risk of accidents. Cannabis impairs a person's driving ability, and THC

13536-436: The following: All of the opioids can cause side effects. Common adverse reactions in patients taking opioids for pain relief include nausea and vomiting, drowsiness , itching, dry mouth, dizziness , and constipation . Tolerance to nausea occurs within 7–10 days, during which antiemetics ( e.g. low dose haloperidol once at night) are very effective. Due to severe side effects such as tardive dyskinesia, haloperidol

13677-429: The greater potency, the standard doses of many synthetic cannabinoids may be less than 1 mg. Most classical, non-classical, and hybrid synthetic cannabinoids have stereospecificity (one stereoisomer is usually much more potent than the other(s)). For example, HU-210 is the (–) enantiomer of 11-OH-Δ-THC-DMH and a full agonist of the CB 1 receptor ; the (+) enantiomer of 11-OH-D-THC-DMH, known as HU-211 ,

13818-723: The grounds that it contains an active substance that affects the functions of the body, and the legality of JWH-018 is under review. JWH-018, CP 47,497 and the C6, C8, and C9 homologues of CP 47,497 have been illegal in Germany since January 22, 2009. Since November 26, 2016, about 80–90% of the substances belonging to the group of synthetic cannabinoids are illegal in Germany as the law does not cover all chemical structures. JWH-018, CP 47,497 (and its homologues), and HU-210 were all made illegal in France on February 24, 2009. From June 2010, JWH-018, along with

13959-417: The initial screening method when testing physiological specimens for marijuana presence, have different degrees of cross-reactivity with THC and its metabolites. Urine contains predominantly THC-COOH, while hair, oral fluid and sweat contain primarily THC. Blood may contain both substances, with the relative amounts dependent on the recency and extent of usage. The Duquenois–Levine test is commonly used as

14100-536: The intake of opioids over days and weeks can reduce or eliminate the withdrawal symptoms. The speed and severity of withdrawal depends on the half-life of the opioid; heroin and morphine withdrawal occur more quickly than methadone withdrawal. The acute withdrawal phase is often followed by a protracted phase of depression and insomnia that can last for months. The symptoms of opioid withdrawal can be treated with other medications, such as clonidine . Physical dependence does not predict drug misuse or true addiction, and

14241-403: The intention of making a synthetic cannabinoid prodrug , which might improve absorption and confound detection. Ester bonds are easily biodegradable through spontaneous or endogenous , nonspecific esterase hydrolysis, which has been commonly used in medicinal chemistry to make ester prodrugs. The reason for the change to the quinolone substructure is unknown, but it may have been found to be

14382-569: The latter substances. Cannabinoid hyperemesis syndrome (CHS) is a severe condition seen in some chronic cannabis users where they have repeated bouts of uncontrollable vomiting for 24–48 hours. Four cases of death have been reported as a result of CHS. A limited number of studies have examined the effects of cannabis smoking on the respiratory system. Chronic heavy marijuana smoking is associated with respiratory infections , coughing, production of sputum, wheezing, and other symptoms of chronic bronchitis. The available evidence does not support

14523-616: The literature found that opioids were not necessarily more effective in treating shortness of breath in patients who have advanced cancer. Though not typically a first line of treatment, opioids, such as oxycodone and methadone , are sometimes used in the treatment of severe and refractory restless legs syndrome . Hyperalgesia Opioid-induced hyperalgesia (OIH) has been evident in patients after chronic opioid exposure. Common and short term Other Each year 69,000 people worldwide die of opioid overdose, and 15 million people have an opioid addiction. In older adults, opioid use

14664-535: The liver (particularly with co-existing hepatitis C ), lungs, heart, and vasculature". A 2014 review found that while cannabis use may be less harmful than alcohol use, the recommendation to substitute it for problematic drinking was premature without further study. Various surveys conducted between 2015 and 2019 found that many users of cannabis substitute it for prescription drugs (including opioids), alcohol, and tobacco; most of those who used it in place of alcohol or tobacco either reduced or stopped their intake of

14805-579: The long-term effects of cannabis on cognition, and the results were generally inconsistent. Furthermore, effect sizes of significant findings were generally small. One review concluded that, although most cognitive faculties were unimpaired by cannabis use, residual deficits occurred in executive functions . Impairments in executive functioning are most consistently found in older populations, which may reflect heavier cannabis exposure, or developmental effects associated with adolescent cannabis use. One review found three prospective cohort studies that examined

14946-817: The most common short-term physical and neurological effects include increased heart rate, increased appetite, impairment of short-term and working memory, and impairment of psychomotor coordination . Additional desired effects from consuming cannabis include relaxation, a general alteration of conscious perception , increased awareness of sensation, increased libido and distortions in the perception of time and space. At higher doses, effects can include altered body image , auditory or visual illusions , pseudohallucinations and ataxia from selective impairment of polysynaptic reflexes . In some cases, cannabis can lead to dissociative states such as depersonalization and derealization . Cannabis has held sacred status in several religions and has served as an entheogen –

15087-421: The most common synthetic cannabinoids found in synthetic cannabinoid blends, likely due to the fact that these molecules are easier to synthesize than classical and non-classical cannabinoids. The JWH molecules were first synthesized by John William Huffman at Clemson University in the late 1990s. The FBI concluded in a 2012 memo that as a result of the publication of J.W. Huffman's research, people searching for

15228-471: The most suitable drug for a particular patient. Otherwise, treatment with CNS stimulants is generally effective. Itching tends not to be a severe problem when opioids are used for pain relief, but antihistamines are useful for counteracting itching when it occurs. Non-sedating antihistamines such as fexofenadine are often preferred as they avoid increasing opioid induced drowsiness. However, some sedating antihistamines such as orphenadrine can produce

15369-444: The name is formatted as LinkedGroup-TailCoreLinker. For example, in 5F-MDMB-PINACA (also known as 5F-ADB ), 5F stands for the terminal fluorine or "fluorine on carbon 5" of the pentyl chain; MDMB stands for "methyl-3,3-dimethyl butanoate", the linked group; and PINACA stands for "pentyl chain (tail) indazole (core) carboxamide (linker)". Use of the term "synthetic marijuana" to describe products containing synthetic cannabinoids

15510-431: The negative effects of 5F-AKB-48 reported by users included palpitations , paranoia , intense anxiety, and a taste like burned plastic. In addition, while there are no fatal overdose cases linked to marijuana , there are deaths linked to synthetic cannabinoids each year. The most common mechanisms leading to death following synthetic cannabinoid use include behavioral risks, such as self-harm and suicide , falling from

15651-490: The people in the United States had tried marijuana, 16% had used it in the past year, and 11% had used it in the past month. In 2014, surveys said daily marijuana use amongst US college students had reached its highest level since records began in 1980, rising from 3.5% in 2007 to 5.9% in 2014 and had surpassed daily cigarette use. In the US, men are over twice as likely to use marijuana as women, and 18–29-year-olds are six times more likely to use as over-65-year-olds. In 2015,

15792-431: The possibility of self-administered zinc producing false-negative urine drug tests. CBD is a 5-HT 1A receptor agonist, which is under laboratory research to determine if it has an anxiolytic effect. It is often claimed that sativa strains provide a more stimulating psychoactive high while indica strains are more sedating with a body high. However, this is disputed by researchers. Opioid Opioids are

15933-513: The potency of illicit cannabis has increased, with THC levels rising and CBD levels dropping. Cannabis plants have been grown since at least the 3rd millennium BCE and there is evidence of it being smoked for its psychoactive effects around 500 BCE in the Pamir Mountains , Central Asia. Since the 14th century, cannabis has been subject to legal restrictions. The possession, use, and cultivation of cannabis has been illegal in most countries since

16074-415: The products. For example, AKB-48 (also known as APINACA ) is also the name of a popular Japanese girl band ; 2NE1 (also known as APICA ) is also a South Korean girl band ; and XLR-11 was named after the first USA-developed liquid fuel rocket for aircraft . Now many synthetic cannabinoids are assigned names derived from their four main structural components, core, tail, linker, and linked group, where

16215-425: The pupil of the eye to less than or equal to two millimeters). This idea has been challenged, however, with some authors arguing that tolerance does develop to miosis. Tolerance to opioids is attenuated by a number of substances, including: Tolerance is a physiologic process where the body adjusts to a medication that is frequently present, usually requiring higher doses of the same medication over time to achieve

16356-542: The rat poison brodifacoum , which is added because it is thought to extend the duration of the drugs' effects. Severe illnesses and death have resulted from this contamination. Synthetic cannabinoids reagent testing kits have recently become economical. It is often difficult to determine what is in these products without reagent testing because masking agents , such as tocopherol (or vitamin E acetate that causes vaping-associated pulmonary injury ), eugenol , and fatty acids , are added to confound identification. Just as

16497-526: The relationship between self-reported cannabis use and intelligence quotient (IQ). The study following the largest number of heavy cannabis users reported that IQ declined between ages 7–13 and age 38. Poorer school performance and increased incidence of leaving school early were both associated with cannabis use, although a causal relationship was not established. Cannabis users demonstrated increased activity in task-related brain regions, consistent with reduced processing efficiency. A reduced quality of life

16638-1166: The restrictions. Synthetic cannabinoids have also been used recreationally because they are inexpensive and are typically not revealed by the standard marijuana drug tests . Unlike nabilone , the synthetic cannabinoids found being used for recreational use did not have any documented therapeutic effects . Because they activate the cannabinoid CB 1 and CB 2 receptors, many of the effects of synthetic cannabinoids are similar to those of THC. These are achieved at lower doses, because many synthetic cannabinoids are more potent than marijuana, and users are often unaware of exactly what they are getting and how potent it is. For example, Δ-THC has an EC 50 of 250 nM at CB 1 and 1157 nM at CB 2 , whereas PB-22 has an EC 50 of 5.1 nM at CB 1 and 37 nM at CB 2 . Adverse effects observed due to synthetic cannabinoid use include acute kidney injury , cardiac toxicity , seizure , stroke , tremor , hypokalemia , and rhabdomyolysis . Some negative effects of 5F-PB-22 reported by users included nausea , vomiting , confusion , poor coordination , anxiety , and seizures. Some of

16779-459: The risk of myocardial infarction by 4.8 times for the 60 minutes after consumption. There is preliminary evidence that cannabis interferes with the anticoagulant properties of prescription drugs used for treating blood clots . As of 2019 , the mechanisms for the anti-inflammatory and possible pain relieving effects of cannabis were not defined, and there were no governmental regulatory approvals or clinical practices for use of cannabis as

16920-537: The risk of psychosis, though the direction of causality is debated. Physical effects include increased heart rate, difficulty breathing, nausea, and behavioral problems in children whose mothers used cannabis during pregnancy; short-term side effects may also include dry mouth and red eyes. Long-term adverse effects may include addiction, decreased mental ability in those who started regular use as adolescents, chronic coughing, susceptibility to respiratory infections , and cannabinoid hyperemesis syndrome . Cannabis

17061-399: The same effect. It is a common occurrence in individuals taking high doses of opioids for extended periods, but does not predict any relationship to misuse or addiction. Physical dependence is the physiological adaptation of the body to the presence of a substance, in this case opioid medication. It is defined by the development of withdrawal symptoms when the substance is discontinued, when

17202-529: The side effects of buprenorphine or methadone . Buprenorphine can also be used together with naloxone for a longer treatment of addiction. In other European countries including the UK, this is also legally used for OST although on a varying scale of acceptance. Slow-release formulations of medications are intended to curb misuse and lower addiction rates while trying to still provide legitimate pain relief and ease of use to pain patients. Questions remain, however, about

17343-449: The sole agent, 66.1% reported problems in the central nervous system (e.g., agitation, coma , toxic psychosis ), 17% reported cardiovascular problems (e.g., tachycardia , bradycardia ), 7.6% reported pulmonary problems (5.4% of which had respiratory depression ), and 4% reported acute kidney injury . Four postmortem cases linked to the synthetic cannabinoids 5F-PB-22 have been reviewed. The postmortem blood specimens contained

17484-461: The specific antibodies in the EMIT for marijuana do not bind to them. Also, due to their high potency , a very small dose of synthetic cannabinoids is used; moreover, synthetic cannabinoids are highly metabolized by the body, so the window to detect the parent drug (the synthetic cannabinoid itself) in blood and oral fluid is very small. Serum concentrations of synthetic cannabinoids are generally in

17625-461: The spiritual use of cannabis has been spread by the disciples of the Rastafari movement who use cannabis as a sacrament and as an aid to meditation. Many different ways to consume cannabis involve heat to decarboxylate THCA into THC; common modes include: In 2013, between 128 and 232 million people used cannabis (2.7% to 4.9% of the global population between the ages of 15 and 65). Cannabis

17766-422: The strain it can place on the cardiovascular system . Some deaths have also been attributed to cannabinoid hyperemesis syndrome . There is an association between cannabis use and suicide, particularly in younger users. A 16-month survey of Oregon and Alaska emergency departments found a report of the death of an adult who had been admitted for acute cannabis toxicity. A 2015 meta-analysis found that, although

17907-472: The structure of a synthetic cannabinoid, such as changing an indole to indazole structure ( AM-2201 to THJ-2201 ) or terminal fluorine replacement; however, one group that was unprecedented when discovered by forensic scientists in 2013, was the quinolinyl ester synthetic cannabinoids. PB-22 and 5F-PB-22 were the first synthetic cannabinoids to include a quinoline substructure and an ester linkage . These compounds are thought to have been synthesized with

18048-765: The synthetic cannabinoid(s) used differ between each synthetic cannabinoid product sold, so do the other contents of the counterfeit product. Synthetic cannabinoids appear in many CBD brands in products such as gummy bears and vape cartridges. Synthetic cannabinoid components of 'Spice' (a non-exhaustive list): Most blends consist of synthetic cannabinoids sprayed onto inert vegetable matter, but some contain other psychoactive substances , including psychoactive herbs, e.g., wild dagga and indian warrior , and psychoactive alkaloids , e.g., betonicine, aporphine , leonurine , nuciferine , and nicotine . Some synthetic cannabinoids products have also been found to contain synthetic opioids . For example, in 2010, nine people died due to

18189-546: The synthetic cannabinoids have been found to be about 2–5 times more potent at CB 1 receptors than their un-fluorinated counterparts, as shown in table two. Synthetic cannabinoids are typically not identified by the standard marijuana drug tests including the immunoassay test ( EMIT ), GC-MS screening, and multi-target screening by LC-GC/MS because those tests only detect the presence of THC and its metabolites. Although most synthetic cannabinoids are analogs of THC, they are structurally different enough that, for example,

18330-548: The term synthetic cannabinoid is more appropriate. Nearly 700 "herbal incense" blends exist. They are often called "synthetic marijuana", "natural herbs", "herbal incense", or "herbal smoking blends" and often labeled "not for human consumption". In some Spanish-speaking countries, such as Chile and Argentina, such preparations are often referred to as cripy . According to the Psychonaut Web Mapping Research Project, synthetic cannabinoids, sold under

18471-423: The toxicity and lethality of THC in children is not known, they are at risk for encephalopathy, hypotension, respiratory depression severe enough to require ventilation, somnolence and coma. There is no clear evidence for a link between cannabis use and deaths from cardiovascular disease, but a 2019 review noted that it may be an under-reported, contributory factor or direct cause in cases of sudden death , due to

18612-435: The treatment of acute cough does not recommend its use. (The opioid analogue dextromethorphan , long claimed to be as effective a cough suppressant as codeine, has similarly demonstrated little benefit in several recent studies. ) Low dose morphine may help chronic cough but its use is limited by side effects. In cases of diarrhea-predominate irritable bowel syndrome , opioids may be used to suppress diarrhea. Loperamide

18753-509: The treatment of choice due to their rapid onset, efficacy and reduced risk of dependence. However, a new report showed a clear risk of prolonged opioid use when opioid analgesics are initiated for an acute pain management following surgery or trauma. They have also been found to be important in palliative care to help with the severe, chronic, disabling pain that may occur in some terminal conditions such as cancer, and degenerative conditions such as rheumatoid arthritis . In many cases opioids are

18894-635: The use of cannabis to treat disease or improve symptoms; however, there is no single agreed-upon definition (e.g., cannabinoids derived from cannabis and synthetic cannabinoids are also used). The rigorous scientific study of cannabis as a medicine has been hampered by production restrictions and by the fact that it is classified as an illegal drug by many governments. There is some evidence suggesting cannabis can be used to reduce nausea and vomiting during chemotherapy , to improve appetite in people with HIV/AIDS , or to treat chronic pain and muscle spasms . Evidence for its use for other medical applications

19035-469: Was determined to be a synthetic cannabinoid called AMB-FUBINACA . Since March 2018, Illinois, Wisconsin, Maryland, and 8 other states in the United States have had an outbreak of severe bleeding caused by a synthetic cannabinoid contaminated with brodifacoum , a rat poison that causes bleeding. Illinois was hit the hardest and on April 5, 2018, the CDC issued a Clinical Action alert to health care providers across

19176-560: Was found). No official studies have been conducted on the effects of synthetic cannabinoids on humans (as is often the case with illegal and potentially toxic compounds); however, user reports and the effects experienced by patients seeking medical care after taking synthetic cannabinoids have been published. Each of the many different synthetic cannabinoids can have different effects at different dosages. The CDC described synthetic cannabinoid overdoses between 2010 and 2015 and of 277 drug overdose patients who reported synthetic cannabinoid as
