97-629: At the time the Republic Act 6425, also known as the Dangerous Drugs Act of 1972, was approved on March 30, 1972, there are 20 thousand drug users and marijuana is the most preferred illegal drug among users in the country. The board was established on November 14, 1972, under the Office of the President after the proclamation of Martial Law in the country by then President Ferdinand Marcos . The DDB

194-576: 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,

291-466: 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

388-451: 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

485-415: 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

582-641: 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

679-426: 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

776-717: A drop in their ordinary ability, whether physical or mental, due to that perceived stress. Competitive anxiety is caused by a range of internal factors including high expectations, outside pressure, lack of experience, and external factors like the location of a competition. It commonly occurs in those participating in high pressure activities like sports and debates. Some common symptoms of competitive anxiety include muscle tension, fatigue, weakness, sense of panic, apprehensiveness, and panic attacks. There are 4 major theories of how anxiety affects performance: Drive theory, Inverted U theory, Reversal theory, and The Zone of Optimal Functioning theory. Drive theory believes that anxiety

873-704: A drug for both recreational and entheogenic purposes and in various traditional medicines for centuries. Tetrahydrocannabinol (THC) 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

970-458: 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

1067-611: 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

1164-476: A fear of rejection and negative evaluation (being judged) by other people. The philosopher Søren Kierkegaard , in The Concept of Anxiety (1844), described anxiety or dread associated with the "dizziness of freedom" and suggested the possibility for positive resolution of anxiety through the self-conscious exercise of responsibility and choosing. In Art and Artist (1932), the psychologist Otto Rank wrote that

1261-420: A heart attack, when in reality all one is experiencing is mild chest pain, for example. The physiological symptoms of anxiety may include: There are various types of anxiety. Existential anxiety can occur when a person faces angst , an existential crisis , or nihilistic feelings. People can also face mathematical anxiety , somatic anxiety , stage fright , or test anxiety . Social anxiety refers to

1358-505: A large influence on anxiety, whereas shared environmental influences (environments that affect twins in the same way) operate during childhood but decline through adolescence. Specific measured 'environments' that have been associated with anxiety include child abuse , family history of mental health disorders, and poverty . Anxiety is also associated with drug use , including alcohol , caffeine , and benzodiazepines , which are often prescribed to treat anxiety. Neural circuitry involving

1455-472: 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

1552-660: A long-term " trait ". Whereas trait anxiety represents worrying about future events, anxiety disorders are a group of mental disorders characterized by feelings of anxiety and fears. In his book Anxious: The Modern Mind in the Age of Anxiety Joseph LeDoux examines four experiences of anxiety through a brain-based lens: Anxiety disorders often occur with other mental health disorders, particularly major depressive disorder , bipolar disorder , eating disorders , or certain personality disorders . It also commonly occurs with personality traits such as neuroticism. This observed co-occurrence

1649-523: 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

1746-528: 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

1843-402: A reward. This suggests a link between circuits responsible for fear and also reward in anxious people. As researchers note, "a sense of 'responsibility', or self-agency, in a context of uncertainty (probabilistic outcomes) drives the neural system underlying appetitive motivation (i.e., nucleus accumbens) more strongly in temperamentally inhibited than noninhibited adolescents". The microbes of

1940-400: A teacher; fear of alienation from parents or friends; time pressures; or feeling a loss of control. Sweating, dizziness, headaches, racing heartbeats, nausea, fidgeting, uncontrollable crying or laughing and drumming on a desk are all common. Because test anxiety hinges on fear of negative evaluation , debate exists as to whether test anxiety is itself a unique anxiety disorder or whether it

2037-440: A trait leading to anxiety and depression and their persistence. Through experience, many find it difficult to collect themselves due to their own personal nature. Anxiety induced by the need to choose between similar options is recognized as a problem for some individuals and for organizations. In 2004, Capgemini wrote: "Today we're all faced with greater choice, more competition and less time to consider our options or seek out

2134-480: Is a feeling of uneasiness and worry , usually generalized and unfocused as an overreaction to a situation that is only subjectively seen as menacing. It is often accompanied by muscular tension, restlessness, fatigue , inability to catch one's breath, tightness in the abdominal region, nausea, and problems in concentration. Anxiety is closely related to fear , which is a response to a real or perceived immediate threat ( fight-or-flight response ); anxiety involves

2231-423: Is a major component of behavioral treatments for anxiety conditions. Performance anxiety and competitive anxiety ( competitive trait anxiety, competitive state anxiety ) happen when an individual's performance is measured against others. An important distinction between competitive and non-competitive anxiety is that competitive anxiety makes people view their performance as a threat. As a result, they experience

2328-518: Is a specific type of social phobia . The DSM-IV classifies test anxiety as a type of social phobia. Research indicates that test anxiety among U.S. high-school and college students has been rising since the late 1950s. Test anxiety remains a challenge for students, regardless of age, and has considerable physiological and psychological impacts. Management of test anxiety focuses on achieving relaxation and developing mechanisms to manage anxiety. The routine practice of slow, Device-Guided Breathing (DGB)

2425-427: Is an emotion which is characterised by an unpleasant state of inner turmoil and includes feelings of dread over anticipated events. Anxiety is different from fear in that fear is defined as the emotional response to a present threat , whereas anxiety is the anticipation of a future one. It is often accompanied by nervous behavior such as pacing back and forth, somatic complaints , and rumination . Anxiety

2522-457: 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

2619-526: 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

2716-528: 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

2813-477: Is characterized by experiencing discomfort or awkwardness during physical social contact (e.g. embracing, shaking hands, etc.), while in other cases it can lead to a fear of interacting with unfamiliar people altogether. Those with this condition may restrict their lifestyles to accommodate the anxiety, minimizing social interaction whenever possible. Social anxiety also forms a core aspect of certain personality disorders, including avoidant personality disorder . To

2910-459: 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

3007-464: Is common among young people. It may persist into adulthood and become social anxiety or social phobia. " Stranger anxiety " in small children is not considered a phobia. In adults, an excessive fear of other people is not a developmentally common stage; it is called social anxiety . According to Cutting, social phobics do not fear the crowd but the fact that they may be judged negatively. Social anxiety varies in degree and severity. For some people, it

3104-436: 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

3201-457: Is distinguished from fear , which is an appropriate cognitive and emotional response to a perceived threat . Anxiety is related to the specific behaviors of fight-or-flight responses , defensive behavior or escape. There is a false presumption that often circulates that anxiety only occurs in situations perceived as uncontrollable or unavoidable, but this is not always so. David Barlow defines anxiety as "a future-oriented mood state in which one

3298-408: 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

3395-447: 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

3492-641: 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

Marijuana 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

3686-404: 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

3783-527: 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

3880-409: 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,

However, when the anxiety or level of arousal exceeds that optimum, the result is a decline in performance. Test anxiety is the uneasiness, apprehension, or nervousness felt by students who have a fear of failing an exam . Students who have test anxiety may experience any of the following: the association of grades with personal worth ; fear of embarrassment by

4074-585: 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

4171-489: Is not built on the rock of reality ". According to Viktor Frankl , the author of Man's Search for Meaning , when a person is faced with extreme mortal dangers, the most basic of all human wishes is to find a meaning of life to combat the "trauma of nonbeing" as death is near. Depending on the source of the threat, psychoanalytic theory distinguishes three types of anxiety: realistic, neurotic and moral. According to Yerkes-Dodson law , an optimal level of arousal

4268-555: Is not ready or prepared to attempt to cope with upcoming negative events," and that it is a distinction between future and present dangers which divides anxiety and fear. Another description of anxiety is agony, dread, terror, or even apprehension. In positive psychology , anxiety is described as the mental state that results from a difficult challenge for which the subject has insufficient coping skills. Fear and anxiety can be differentiated into four domains: (1) duration of emotional experience, (2) temporal focus, (3) specificity of

4365-910: Is often called interracial or intergroup anxiety. As is the case with the more generalized forms of social anxiety , intergroup anxiety has behavioral, cognitive, and affective effects. For instance, increases in schematic processing and simplified information processing can occur when anxiety is high. Indeed, such is consistent with related work on attentional bias in implicit memory . Additionally recent research has found that implicit racial evaluations (i.e. automatic prejudiced attitudes) can be amplified during intergroup interaction. Negative experiences have been illustrated in producing not only negative expectations, but also avoidant, or antagonistic, behavior such as hostility. Furthermore, when compared to anxiety levels and cognitive effort (e.g., impression management and self-presentation) in intragroup contexts, levels and depletion of resources may be exacerbated in

4462-414: Is partly due to genetic and environmental influences shared between these traits and anxiety. It is common for those with obsessive–compulsive disorder to experience anxiety. Anxiety is also commonly found in those who experience panic disorders , phobic anxiety disorders , severe stress , dissociative disorders , somatoform disorders , and some neurotic disorders . Anxiety has also been linked to

4559-701: Is positive and performance improves proportionally to the level of anxiety. This theory is not well accepted. The Inverted U theory is based on the idea that performance peaks at a moderate stress level. It is called Inverted U theory because the graph that plots performance against anxiety looks like an inverted "U". Reversal theory suggests that performance increases in relation to the individual's interpretation of their arousal levels. If they believed their physical arousal level would help them, their performance would increase, if they didn't, their performance would decrease. For example: Athletes were shown to worry more when focusing on results and perfection rather than

4656-463: Is reported by the Cleveland Clinic that panic disorder affects 2 to 3 percent of adult Americans and can begin around the time of the teenage and early adult years. Some symptoms include: difficulty breathing, chest pain, dizziness, trembling or shaking, feeling faint, nausea, fear that you are losing control or are about to die. Even though they have these symptoms during an attack, the main symptom

4753-406: Is that people with an anxiety disorder experience anxiety excessively or persistently during approximately 6 months, or even during shorter time-periods in children. Anxiety disorders are among the most persistent mental problems and often last decades. Anxiety can also be experienced within other mental disorders , e.g., obsessive-compulsive disorder , post-traumatic stress disorder . Anxiety

4850-608: Is the persistent fear of having future panic attacks. Anxiety disorders are a group of mental disorders characterized by exaggerated feelings of anxiety and fear responses. Anxiety is a worry about future events and fear is a reaction to current events. These feelings may cause physical symptoms, such as a fast heart rate and shakiness. There are a number of anxiety disorders: including generalized anxiety disorder , specific phobia , social anxiety disorder , separation anxiety disorder , agoraphobia , panic disorder , and selective mutism . The disorder differs by what results in

4947-460: Is typically with a type of cognitive behavioral therapy . Medications, such as antidepressants or beta blockers , may improve symptoms. A 2023 review found that regular physical activity is effective for reducing anxiety. About 12% of people are affected by an anxiety disorder in a given year and between 12% and 30% are affected at some point in their life. They occur about twice as often in women than they do in men, and generally begin before

5044-467: The amygdala , which regulates emotions like anxiety and fear, stimulating the HPA axis and sympathetic nervous system , and hippocampus , which is implicated in emotional memory along with the amygdala, is thought to underlie anxiety. People who have anxiety tend to show high activity in response to emotional stimuli in the amygdala. Some writers believe that excessive anxiety can lead to an overpotentiation of

5141-399: The limbic system (which includes the amygdala and nucleus accumbens), giving increased future anxiety, but this does not appear to have been proven. Research upon adolescents who as infants had been highly apprehensive, vigilant, and fearful finds that their nucleus accumbens is more sensitive than that in other people when deciding to make an action that determined whether they received

5238-561: The psychological trauma of birth was the pre-eminent human symbol of existential anxiety and encompasses the creative person's simultaneous fear of – and desire for – separation, individuation, and differentiation. The theologian Paul Tillich characterized existential anxiety as "the state in which a being is aware of its possible nonbeing" and he listed three categories for the nonbeing and resulting anxiety: ontic (fate and death), moral ( guilt and condemnation), and spiritual (emptiness and meaninglessness ). According to Tillich,

5335-415: 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

5432-455: 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

5529-507: 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

5626-489: 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

5723-402: The age of 25. The most common anxiety disorders are specific phobias, which affect nearly 12% of people, and social anxiety disorder, which affects 10% of people at some point in their life. They affect those between the ages of 15 and 35 the most and become less common after the age of 55. Rates appear to be higher in the United States and Europe. Anxiety can be either a short-term "state" or

5820-423: 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

5917-406: 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).

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

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,

6402-525: The effort and growth involved. The Zone of Optimal Functioning theory proposes that there is a zone where positive and negative emotions are in a balance which lead to feelings of dissociation and intense concentration, optimizing the individual's performance levels. Humans generally require social acceptance and thus sometimes dread the disapproval of others. Apprehension of being judged by others may cause anxiety in social environments. Anxiety during social interactions, particularly between strangers,

6499-418: 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

6596-487: The expectation of a future threat including dread. People facing anxiety may withdraw from situations which have provoked anxiety in the past. The emotion of anxiety can persist beyond the developmentally appropriate time-periods in response to specific events, and thus turning into one of the multiple anxiety disorders (e.g. generalized anxiety disorder , panic disorder ). The difference between anxiety disorder (as mental disorder ) and anxiety (as normal emotion),

6693-529: The experience of intrusive thoughts . Studies have revealed that individuals who experience high levels of anxiety (also known as clinical anxiety) are highly vulnerable to the experience of intense intrusive thoughts or psychological disorders that are characterised by intrusive thoughts. Anxiety disorders are partly genetic, with twin studies suggesting 30-40% genetic influence on individual differences in anxiety. Environmental factors are also important. Twin studies show that individual-specific environments have

6790-486: The extent that a person is fearful of social encounters with unfamiliar others, some people may experience anxiety particularly during interactions with outgroup members, or people who share different group memberships (i.e., by race, ethnicity, class, gender, etc.). Depending on the nature of the antecedent relations, cognitions, and situational factors, intergroup contact may be stressful and lead to feelings of anxiety. This apprehension or fear of contact with outgroup members

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

6984-424: The gut can connect with the brain to affect anxiety. There are various pathways along which this communication can take place. One is through the major neurotransmitters . The gut microbes such as Bifidobacterium and Bacillus produce the neurotransmitters GABA and dopamine , respectively. The neurotransmitters signal to the nervous system of the gastrointestinal tract, and those signals will be carried to

7081-417: 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

7178-511: The intergroup situation. Anxiety can be either a short-term "state" or a long-term " personality trait". Trait anxiety reflects a stable tendency across the lifespan of responding with acute, state anxiety in the anticipation of threatening situations (whether they are actually deemed threatening or not). A meta-analysis showed that a high level of neuroticism is a risk factor for development of anxiety symptoms and disorders. Such anxiety may be conscious or unconscious. Personality can also be

7275-519: The last of these three types of existential anxiety, i.e. spiritual anxiety, is predominant in modern times while the others were predominant in earlier periods. Tillich argues that this anxiety can be accepted as part of the human condition or it can be resisted but with negative consequences. In its pathological form, spiritual anxiety may tend to "drive the person toward the creation of certitude in systems of meaning which are supported by tradition and authority " even though such "undoubted certitude

7372-569: 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

7469-535: 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

7566-579: 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

7663-817: 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 –

7760-490: 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,

7857-650: The person. However, most people do not suffer from chronic anxiety. Anxiety can induce several psychological pains (e.g. depression ) or mental disorders , and may lead to self-harm or suicide . The behavioral effects of anxiety may include withdrawal from situations which have provoked anxiety or negative feelings in the past. Other effects may include changes in sleeping patterns, changes in habits, increase or decrease in food intake, and increased motor tension (such as foot tapping). The emotional effects of anxiety may include feelings of apprehension or dread, trouble concentrating, feeling tense or jumpy, anticipating

7954-427: 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. Anxiety Anxiety

8051-513: 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

8148-526: 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

8245-428: The right advice." Overthinking a choice is called analysis paralysis . In a decision context, unpredictability or uncertainty may trigger emotional responses in anxious individuals that systematically alter decision-making. There are primarily two forms of this anxiety type. The first form refers to a choice in which there are multiple potential outcomes with known or calculable probabilities. The second form refers to

8342-459: 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

8439-537: 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

8536-461: 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

8633-422: 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

8730-689: The symptoms. People often have more than one anxiety disorder. Anxiety disorders are caused by a complex combination of genetic and environmental factors. To be diagnosed, symptoms typically need to be present for at least six months, be more than would be expected for the situation, and decrease a person's ability to function in their daily lives. Other problems that may result in similar symptoms include hyperthyroidism , heart disease , caffeine , alcohol , or cannabis use, and withdrawal from certain drugs, among others. Without treatment, anxiety disorders tend to remain. Treatment may include lifestyle changes, counselling , and medications. Counselling

8827-854: The threat, and (4) motivated direction. Fear is short-lived, present-focused, geared towards a specific threat, and facilitating escape from threat. On the other hand, anxiety is long-acting, future-focused, broadly focused towards a diffuse threat, and promoting excessive caution while approaching a potential threat and interferes with constructive coping. Joseph E. LeDoux and Lisa Feldman Barrett have both sought to separate automatic threat responses from additional associated cognitive activity within anxiety. Anxiety can be experienced with long, drawn-out daily symptoms that reduce quality of life, known as chronic (or generalized) anxiety, or it can be experienced in short spurts with sporadic, stressful panic attacks , known as acute anxiety. Symptoms of anxiety can range in number, intensity, and frequency, depending on

8924-423: 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

9021-649: The uncertainty and ambiguity related to a decision context in which there are multiple possible outcomes with unknown probabilities. Panic disorder may share symptoms of stress and anxiety, but it is actually very different. Panic disorder is an anxiety disorder that occurs without any triggers. According to the U.S. Department of Health and Human Services, this disorder can be distinguished by unexpected and repeated episodes of intense fear. Someone with panic disorder will eventually develop constant fear of another attack and as this progresses it will begin to affect daily functioning and an individual's general quality of life. It

9118-635: 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

9215-442: The worst, irritability, restlessness, watching for signs of danger, and a feeling of empty mindedness. as well as "nightmares/bad dreams, obsessions about sensations, déjà vu , a trapped-in-your-mind feeling, and feeling like everything is scary." It may include a vague experience and feeling of helplessness. The cognitive effects of anxiety may include thoughts about suspected dangers, such as an irrational fear of dying or having

9312-406: Was mandated to be the policy-making and coordinating agency as well as the national clearing house on all matters pertaining to law enforcement and control of dangerous drugs; treatment and rehabilitation of drug dependents; drug abuse prevention, training and information; research and statistics on the drug problem and the training of personnel engaged in these activities. Seven national agencies in

9409-440: Was the illicit drug most frequently found in the blood of drivers who have been involved in vehicle crashes. Those with THC in their system are from three to seven times more likely to be the cause of the accident than those who had not used either cannabis or alcohol, although its role is not necessarily causal because THC stays in the bloodstream for days to weeks after intoxication. Some immediate undesired side effects include
