65-509: According to the 2014 national census in Morocco, the province has more than 457,432 inhabitants. The population is 87.45% rural. The province of Chefchaouen is bordered by five provinces – Tétouan Province to the northwest, Larache Province to the west, Al Hoceïma Province to the east, Taounate Province to the south, Ouezzane Province to the southwest – and the Mediterranean Sea to

130-520: 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 language as qaneh bosem ( קָנֶה בֹּשׂם ). Cannabis is an annual , dioecious , flowering herb . The leaves are palmately compound or digitate , with serrate leaflets . The first pair of leaves usually have

195-416: A chromosome complement of 2n=20, although polyploid individuals have been artificially produced. The first genome sequence of Cannabis , which is estimated to be 820 Mb in size, was published in 2011 by a team of Canadian scientists. The genus Cannabis was formerly placed in the nettle family ( Urticaceae ) or mulberry family ( Moraceae ), and later, along with the genus Humulus ( hops ), in

260-494: A genetic analysis of the same set of accessions led to a three-species classification, recognizing C. sativa , C. indica , and (tentatively) C. ruderalis . Another paper in the series on chemotaxonomic variation in the terpenoid content of the essential oil of Cannabis revealed that several wide-leaflet drug strains in the collection had relatively high levels of certain sesquiterpene alcohols, including guaiol and isomers of eudesmol, that set them apart from

325-533: A four group division: In 1785, evolutionary biologist Jean-Baptiste de Lamarck published a description of a second species of Cannabis , which he named Cannabis indica Lam. Lamarck based his description of the newly named species on morphological aspects (trichomes, leaf shape) and geographic localization of plant specimens collected in India. He described C. indica as having poorer fiber quality than C. sativa , but greater utility as an inebriant . Also, C. indica

390-1083: A high degree of potential variation for selection, even in heavily selected hemp cultivars. They also commented that these analyses confirm the continuity of the Cannabis gene pool throughout the studied accessions, and provide further confirmation that the genus consists of a single species, although theirs was not a systematic study per se . An investigation of genetic, morphological, and chemotaxonomic variation among 157 Cannabis accessions of known geographic origin, including fiber, drug, and feral populations showed cannabinoid variation in Cannabis germplasm . The patterns of cannabinoid variation support recognition of C. sativa and C. indica as separate species, but not C. ruderalis . C. sativa contains fiber and seed landraces, and feral populations, derived from Europe, Central Asia, and Turkey . Narrow-leaflet and wide-leaflet drug accessions, southern and eastern Asian hemp accessions, and feral Himalayan populations were assigned to C. indica . In 2005,

455-417: A large number of chemicals as part of their defense against herbivory . One group of these is called cannabinoids , which induce mental and physical effects when consumed . Cannabinoids, terpenes , terpenoids , and other compounds are secreted by glandular trichomes that occur most abundantly on the floral calyxes and bracts of female plants. Cannabis , like many organisms, is diploid , having

520-399: A long history of being used for medicinal purposes , and as a recreational drug known as marijuana or weed . Various cannabis strains have been bred, often selectively to produce high or low levels of tetrahydrocannabinol (THC), a cannabinoid and the plant's principal psychoactive constituent . Compounds such as hashish and hash oil are extracted from the plant. Cannabis is

585-413: A mature plant. The leaves have a peculiar and diagnostic venation pattern (which varies slightly among varieties) that allows for easy identification of Cannabis leaves from unrelated species with similar leaves. As is common in serrated leaves, each serration has a central vein extending to its tip, but in Cannabis this originates from lower down the central vein of the leaflet, typically opposite to

650-518: A mind-altering drug has been documented by archaeological finds in prehistoric societies in Eurasia and Africa. The oldest written record of cannabis usage is the Greek historian Herodotus 's reference to the central Eurasian Scythians taking cannabis steam baths. His ( c.  440 BCE ) Histories records, "The Scythians, as I said, take some of this hemp-seed [presumably, flowers], and, creeping under

The industrial sector remains very weak despite the province's potential with its availability of human and natural resources. The commercial sector is one of the main economic supports of Chefchaouen, bolstered by tourism activity and remittances from workers abroad. It is mainly focused on urban centers and

780-637: A separate family, the hemp family (Cannabaceae sensu stricto ). Recent phylogenetic studies based on cpDNA restriction site analysis and gene sequencing strongly suggest that the Cannabaceae sensu stricto arose from within the former family Celtidaceae, and that the two families should be merged to form a single monophyletic family, the Cannabaceae sensu lato . Various types of Cannabis have been described, and variously classified as species , subspecies , or varieties : Cannabis plants produce

845-411: A single leaflet , the number gradually increasing up to a maximum of about thirteen leaflets per leaf (usually seven or nine), depending on variety and growing conditions. At the top of a flowering plant , this number again diminishes to a single leaflet per leaf. The lower leaf pairs usually occur in an opposite leaf arrangement and the upper leaf pairs in an alternate arrangement on the main stem of

910-510: A single undivided species. The genus is widely accepted as being indigenous to and originating from Asia . The plant is also known as hemp , although this term is often used to refer only to varieties of Cannabis cultivated for non-drug use. Cannabis has long been used for hemp fibre , hemp seeds and their oils , hemp leaves for use as vegetables and as juice . Industrial hemp products are made from cannabis plants selected to produce an abundance of fibre. Cannabis also has

975-739: A subject of debate for well over two centuries. This is a contentious issue because there is no universally accepted definition of a species . One widely applied criterion for species recognition is that species are "groups of actually or potentially interbreeding natural populations which are reproductively isolated from other such groups." Populations that are physiologically capable of interbreeding, but morphologically or genetically divergent and isolated by geography or ecology, are sometimes considered to be separate species. Physiological barriers to reproduction are not known to occur within Cannabis , and plants from widely divergent sources are interfertile. However, physical barriers to gene exchange (such as

1040-522: A taxonomic revision that recognizes a single species of Cannabis with two subspecies (hemp or drug; based on THC and CBD levels) and two varieties in each (domesticated or wild). The framework is thus: This classification was based on several factors including interfertility, chromosome uniformity, chemotype, and numerical analysis of phenotypic characters. Professors William Emboden, Loran Anderson, and Harvard botanist Richard E. Schultes and coworkers also conducted taxonomic studies of Cannabis in

1105-590: A three species system, independently reinforced by Schultes et al (1975) and Emboden (1974): C. sativa , C. indica and C. ruderalis. In 1940, Russian botanists Serebriakova and Sizov proposed a complex poly-species classification in which they also recognized C. sativa and C. indica as separate species. Within C. sativa they recognized two subspecies: C. sativa L. subsp. culta Serebr. (consisting of cultivated plants), and C. sativa L. subsp. spontanea (Vav.) Serebr. (consisting of wild or feral plants). Serebriakova and Sizov split

1170-450: A unique family of terpeno-phenolic compounds called cannabinoids, some of which produce the "high" which may be experienced from consuming marijuana. There are 483 identifiable chemical constituents known to exist in the cannabis plant, and at least 85 different cannabinoids have been isolated from the plant. The two cannabinoids usually produced in greatest abundance are cannabidiol (CBD) and/or Δ - tetrahydrocannabinol (THC), but only THC

1235-400: Is a genus of flowering plants in the family Cannabaceae . The number of species within the genus is disputed. Three species may be recognized: Cannabis sativa , C. indica , and C. ruderalis . Alternatively, C. ruderalis may be included within C. sativa , or all three may be treated as subspecies of C. sativa , or C. sativa may be accepted as

1300-562: Is a stub . You can help Misplaced Pages by expanding it . Moroccan census The Moroccan Census of the population, officially named general census of the population and the habitat (RGPH), is a census taking place every ten years in the kingdom. It is established under the responsibility of the High Commissioner for Planning. In Morocco under French protectorate or Spanish protectorate, counts were made, spreading irregularly from 1921 to 1951. In 1960 (under Mohammed V ), soon after

1365-1000: Is commonly described as "auto-flowering" and may be day-neutral . Cannabis is predominantly dioecious , having imperfect flowers , with staminate "male" and pistillate "female" flowers occurring on separate plants. "At a very early period the Chinese recognized the Cannabis plant as dioecious", and the (c. 3rd century BCE) Erya dictionary defined xi 枲 "male Cannabis " and fu 莩 (or ju 苴 ) "female Cannabis ". Male flowers are normally borne on loose panicles , and female flowers are borne on racemes . Many monoecious varieties have also been described, in which individual plants bear both male and female flowers. (Although monoecious plants are often referred to as "hermaphrodites", true hermaphrodites – which are less common in Cannabis – bear staminate and pistillate structures together on individual flowers, whereas monoecious plants bear male and female flowers at different locations on

1430-440: Is considered one of the richest regions in terms of biological diversity. It is designated as a Mediterranean biodiversity hotspot (i.e. a zone with an exceptional concentration of endemic and threatened species) and suffers from accelerated forest degradation due to anthropogenic pressures exacerbated by the impact of climate change . Two protected areas have been created in the province: In 2006, these two parks were included in

1495-488: Is determined or strongly influenced by environmental factors. Ainsworth reviews that treatment with auxin and ethylene have feminizing effects, and that treatment with cytokinins and gibberellins have masculinizing effects. It has been reported that sex can be reversed in Cannabis using chemical treatment. A polymerase chain reaction -based method for the detection of female-associated DNA polymorphisms by genotyping has been developed. Cannabis plants produce

1560-556: Is either a variety of C. sativa or a separate species, and proposed C. sativa L. var. ruderalis Janisch, and Cannabis ruderalis Janisch, as alternative names. In 1929, renowned plant explorer Nikolai Vavilov assigned wild or feral populations of Cannabis in Afghanistan to C. indica Lam. var. kafiristanica Vav., and ruderal populations in Europe to C. sativa L. var. spontanea Vav. Vavilov, in 1931, proposed

1625-400: Is most conveniently answered if such chromosomes were clearly visible in a karyotype . Cannabis was one of the first plant species to be karyotyped; however, this was in a period when karyotype preparation was primitive by modern standards. Heteromorphic sex chromosomes were reported to occur in staminate individuals of dioecious "Kentucky" hemp, but were not found in pistillate individuals of

1690-475: Is not surprising that male-associated markers are relatively abundant. In dioecious plants where sex chromosomes have not been identified, markers for maleness indicate either the presence of sex chromosomes which have not been distinguished by cytological methods or that the marker is tightly linked to a gene involved in sex determination. Environmental sex determination is known to occur in a variety of species. Many researchers have suggested that sex in Cannabis

1755-401: Is possibly as a result of inbreeding . Cannabis has been described as having one of the most complicated mechanisms of sex determination among the dioecious plants. Many models have been proposed to explain sex determination in Cannabis . Based on studies of sex reversal in hemp , it was first reported by K. Hirata in 1924 that an XY sex-determination system is present. At the time,

1820-627: Is psychoactive. Since the early 1970s, Cannabis plants have been categorized by their chemical phenotype or "chemotype", based on the overall amount of THC produced, and on the ratio of THC to CBD. Although overall cannabinoid production is influenced by environmental factors, the THC/CBD ratio is genetically determined and remains fixed throughout the life of a plant. Non-drug plants produce relatively low levels of THC and high levels of CBD, while drug plants produce high levels of THC and low levels of CBD. When plants of these two chemotypes cross-pollinate,

1885-546: Is relatively uncommon in the plant kingdom, and a very low percentage of dioecious plant species have been determined to use the XY system. In most cases where the XY system is found it is believed to have evolved recently and independently. Since the 1920s, a number of sex determination models have been proposed for Cannabis . Ainsworth describes sex determination in the genus as using "an X/autosome dosage type". The question of whether heteromorphic sex chromosomes are indeed present

1950-525: Is shorter, conical in shape, and has relatively wide leaflets, and C. ruderalis is short, branchless, and grows wild in Central Asia . This taxonomic interpretation was embraced by Cannabis aficionados who commonly distinguish narrow-leafed "sativa" strains from wide-leafed "indica" strains. McPartland's review finds the Schultes taxonomy inconsistent with prior work (protologs) and partly responsible for

2015-557: Is slightly larger than the X, but difficult to differentiate cytologically. More recently, Sakamoto and various co-authors have used random amplification of polymorphic DNA (RAPD) to isolate several genetic marker sequences that they name Male-Associated DNA in Cannabis (MADC), and which they interpret as indirect evidence of a male chromosome. Several other research groups have reported identification of male-associated markers using RAPD and amplified fragment length polymorphism . Ainsworth commented on these findings, stating, It

2080-698: Is the most widespread variety, which is usually tall, laxly branched, and found in warm lowland regions. "Indica" designates shorter, bushier plants adapted to cooler climates and highland environments. "Ruderalis" is the informal name for the short plants that grow wild in Europe and Central Asia. Mapping the morphological concepts to scientific names in the Small 1976 framework, "Sativa" generally refers to C. sativa subsp. indica var. indica , "Indica" generally refers to C. sativa subsp. i. kafiristanica (also known as afghanica ), and "Ruderalis", being lower in THC,

2145-754: Is the one that can fall into C. sativa subsp. sativa . The three names fit in Schultes's framework better, if one overlooks its inconsistencies with prior work. Definitions of the three terms using factors other than morphology produces different, often conflicting results. Breeders, seed companies, and cultivators of drug type Cannabis often describe the ancestry or gross phenotypic characteristics of cultivars by categorizing them as "pure indica", "mostly indica", "indica/sativa", "mostly sativa", or "pure sativa". These categories are highly arbitrary, however: one "AK-47" hybrid strain has received both "Best Sativa" and "Best Indica" awards. Cannabis likely split from its closest relative, Humulus (hops), during

Despite the significant rainfall, agricultural activity is limited due to the rugged and steep topography, the scarcity of arable land, the low mechanization level, and the lack of irrigation infrastructure. These factors have contributed to the emergence of traditional agriculture largely dependent on climatic hazards. Forests have been harvested for wood and pulp products and to clear land for agriculture. Villagers from rural areas form an important workforce in

Reforestation programs have been carried out since 1966, and by 2016 had generated 16,119 ha (39,830 acres). High rainfall at altitude provides a potential for hydrological development. Several seasonal rivers flow into the Mediterranean or feed

2340-455: The United States and Canada specifically named products of C. sativa as prohibited materials. Enterprising attorneys for the defense in a few drug busts argued that the seized Cannabis material may not have been C. sativa , and was therefore not prohibited by law. Attorneys on both sides recruited botanists to provide expert testimony. Among those testifying for the prosecution

2405-497: The "modern" system of taxonomic nomenclature by Carl Linnaeus in 1753, who devised the system still in use for the naming of species. He considered the genus to be monotypic, having just a single species that he named Cannabis sativa L. Linnaeus was familiar with European hemp, which was widely cultivated at the time. This classification was supported by Christiaan Hendrik Persoon (in 1807), Lindley (in 1838) and De Candollee (in 1867). These first classification attempts resulted in

2470-456: The 1970s, and concluded that stable morphological differences exist that support recognition of at least three species, C. sativa , C. indica , and C. ruderalis. For Schultes, this was a reversal of his previous interpretation that Cannabis is monotypic, with only a single species. According to Schultes' and Anderson's descriptions, C. sativa is tall and laxly branched with relatively narrow leaflets, C. indica

2535-462: The Himalayan mountain range) might have enabled Cannabis gene pools to diverge before the onset of human intervention, resulting in speciation. It remains controversial whether sufficient morphological and genetic divergence occurs within the genus as a result of geographical or ecological isolation to justify recognition of more than one species. The genus Cannabis was first classified using

2600-565: The Middle East, use spread throughout the Islamic empire to North Africa. In 1545, cannabis spread to the western hemisphere where Spaniards imported it to Chile for its use as fiber. In North America, cannabis, in the form of hemp, was grown for use in rope, cloth and paper. Cannabinol (CBN) was the first compound to be isolated from cannabis extract in the late 1800s. Its structure and chemical synthesis were achieved by 1940, followed by some of

2665-549: The XY system was the only known system of sex determination. The X:A system was first described in Drosophila spp in 1925. Soon thereafter, Schaffner disputed Hirata's interpretation, and published results from his own studies of sex reversal in hemp, concluding that an X:A system was in use and that furthermore sex was strongly influenced by environmental conditions. Since then, many different types of sex determination systems have been discovered, particularly in plants. Dioecy

2730-676: The agricultural field. The province is dominated by cereal agriculture, goat herding in the mountains, and arboriculture of fig and almond trees. The countryside has a reputation as a prolific source of kief . The Chefchaouen region is one of the main producers of cannabis in Morocco. This traditional agro-pastoral system – of olive and fig plantations, cereal fields, and limited grazing pastures – has been carried out for centuries. Local products are also diversified, such as fresh goat cheese and other animal products, medicinal and aromatic plants, and products based on wild olives, figs, wool, etc. These various agricultural models have contributed to

2795-467: The choice to use the term "Indian hemp" (linked to the plant's history in India), hence naming the species as indica. Additional Cannabis species were proposed in the 19th century, including strains from China and Vietnam (Indo-China) assigned the names Cannabis chinensis Delile, and Cannabis gigantea Delile ex Vilmorin. However, many taxonomists found these putative species difficult to distinguish. In

Dioecious varieties are also preferred for textile fiber production, whereas monoecious varieties are preferred for pulp and paper production. It has been suggested that the presence of monoecy can be used to differentiate licit crops of monoecious hemp from illicit drug crops, but sativa strains often produce monoecious individuals, which

The oldest known Cannabis in South Asia dates to around 32,000 years ago. Cannabis is used for a wide variety of purposes. According to genetic and archaeological evidence, cannabis was first domesticated about 12,000 years ago in East Asia during the early Neolithic period. The use of cannabis as

3055-527: The early 20th century, the single-species concept (monotypic classification) was still widely accepted, except in the Soviet Union , where Cannabis continued to be the subject of active taxonomic study. The name Cannabis indica was listed in various Pharmacopoeias , and was widely used to designate Cannabis suitable for the manufacture of medicinal preparations. In 1924, Russian botanist D.E. Janichevsky concluded that ruderal Cannabis in central Russia

Classical Greeks and Romans also used cannabis. In China, the psychoactive properties of cannabis are described in the Shennong Bencaojing (3rd century AD). Cannabis smoke was inhaled by Daoists , who burned it in incense burners. In

The Province of Chefchaouen belongs to the Tanger-Tetouan-Al Hoceima Region and consists of one urban commune (the municipality of Chefchaouen) and 27 rural communes, giving the province a rural character. The city of Chefchaouen is the only official municipality in the province, created in 1975. The other major towns are: The province is divided administratively into the following: The Chefchaouen Mountains are composed of very rugged siliceous and limestone layers, with some peaks exceeding 2,000 m (6,600 ft) above sea level, such as Jbel Lakraa and Jbel Tissouka in

A 2020 analysis of single-nucleotide polymorphisms reports five clusters of cannabis , roughly corresponding to hemps (including folk "Ruderalis") folk "Indica" and folk "Sativa". Despite advanced analytical techniques, much of the cannabis used recreationally is inaccurately classified. One laboratory at the University of British Columbia found that Jamaican Lamb's Bread, claimed to be 100% sativa,

This has resulted in many reclassifications based on evolutionary systematics . Several studies of random amplified polymorphic DNA (RAPD) and other types of genetic markers have been conducted on drug and fiber strains of Cannabis , primarily for plant breeding and forensic purposes. Dutch Cannabis researcher E.P.M. de Meijer and coworkers described some of their RAPD studies as showing an "extremely high" degree of genetic polymorphism between and within populations, suggesting

Legalization of cannabis in Canada (as of 17 October 2018 ) may help spur private-sector research, especially in terms of diversification of strains. It should also improve classification accuracy for cannabis used recreationally. Legalization coupled with Canadian government (Health Canada) oversight of production and labelling will likely result in more—and more accurate—testing to determine exact strains and content. Furthermore,
