Near the head and foot of the shaman was a large leather basket and wooden bowl filled with 789g of cannabis, superbly preserved by climatic and burial conditions.

It is also known as hemp, although this term is often used to refer only to varieties of Cannabis cultivated for non-drug use. ruderalis), which is commonly described as "auto-flowering" and may be day-neutral. In the 1970s, the taxonomic classification of Cannabis took on added significance in North America. Indica designates shorter, bushier plants adapted to cooler climates and highland environments.

Cannabis normally has imperfect flowers, with staminate "male" and pistillate "female" flowers occurring on separate plants. Cannabis plants produce a group of chemicals called cannabinoids, which produce mental and physical effects when consumed. sativa subspecies into 13 varieties, including four distinct groups within subspecies culta. Laws prohibiting Cannabis in the United States and Canada specifically named products of C. Enterprising attorneys for the defense in a few drug busts argued that the seized Cannabis material may not have been C. Attorneys on both sides recruited botanists to provide expert testimony. Ruderalis is the informal name for the short plants that grow wild in Europe and central Asia.

This is a contentious issue because there is no universally accepted definition of a species. Normal cognition is restored after approximately three hours for larger doses via a smoking pipe, bong or vaporizer.

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." 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. However, if a large amount is taken orally the effects may last much longer.

Cannabis has long been used for hemp fibre, for hemp oils, for medicinal purposes, and as a recreational drug.

Industrial hemp products are made from cannabis plants selected to produce an abundance of fiber.

Various compounds, including hashish and hash oil, are extracted from the plant. as a wild or escaped variety of the high-intoxicant type.

The first pair of leaves usually have 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. This classification was based on several factors including interfertility, chromosome uniformity, chemotype, and numerical analysis of phenotypic characters. According to Schultes' and Anderson's descriptions, C.

However, the serration vein originates from lower down the central vein of the leaflet, typically opposite to the position of, not the first notch down, but the next notch. The authors hypothesized that the two subspecies diverged primarily as a result of human selection; C. sativa was presumably selected for traits that enhance fiber or seed production, whereas C. Molecular analytical techniques developed in the late 20th century are being applied to questions of taxonomic classification. de Meijer and coworkers described some of their RAPD studies as showing an "extremely high" degree of genetic polymorphism between and within populations, suggesting a high degree of potential variation for selection, even in heavily selected hemp cultivars. In his doctoral dissertation published the same year, Hillig stated that principal components analysis of phenotypic (morphological) traits failed to differentiate the putative species, but that canonical variates analysis resulted in a high degree of discrimination of the putative species and infraspecific taxa.

This means that on its way from the midrib of the leaflet to the point of the serration, the vein serving the tip of the serration passes close by the intervening notch. This has resulted in many reclassifications based on evolutionary systematics. 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. Hillig, a graduate student in the laboratory of long-time Cannabis researcher Paul G. 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 the other putative taxa. He also concluded there is little support to treat C. sativa at this time, but more research on wild and weedy populations is needed because they were underrepresented in their collection.

He considered the genus to be monotypic, having just a single species that he named Cannabis sativa L. stands for Linnaeus, and indicates the authority who first named the species). Cannabis sativa cultivars are used for fibers due to their long stems; Sativa varieties may grow more than six metres tall.
