He is thought to have belonged to the Jushi culture recorded in the area centuries later in the Hanshu, Chap 96B.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.Tiny samples of Cannabis plants also can be identified with precision by microscopic examination of leaf cells and similar features, but that requires special expertise and equipment. sativa proved too unwieldy, and never gained many adherents. and American taxonomist Arthur Cronquist published a taxonomic revision that recognizes a single species of Cannabis with two subspecies: C. Sativa is the most widespread variety, which is usually tall, laxly branched, and found in warm lowland regions.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.Male flowers are normally borne on loose panicles, and female flowers are borne on racemes. The genus Cannabis was formerly placed in the Nettle (Urticaceae) or Mulberry (Moraceae) family, and later, along with the Humulus genus (hops), in a separate family, the Hemp family (Cannabaceae sensu stricto). In the United States alone, it is believed that over 100 million Americans have tried cannabis, with 25 million Americans having used it within the past year.Recent phylogenetic studies based on cp DNA restriction site analysis and gene sequencing strongly suggest that the Cannabaceae sensu stricto arose from within the former Celtidaceae family, and that the two families should be merged to form a single monophyletic family, the Cannabaceae sensu lato. The psychoactive effects of cannabis are known to have a triphasic nature.At the top of a flowering plant, this number again diminishes to a single leaflet per leaf. Schultes and coworkers also conducted taxonomic studies of Cannabis in the 1970s, and concluded that stable morphological differences exist that support recognition of at least three species, C. indica is shorter, conical in shape, and has relatively wide leaflets, and C.
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.
Its use as a mind-altering drug has been documented by archaeological finds in prehistoric societies in Eurasia and Africa. 440 BCE) Histories records, "The Scythians, as I said, take some of this hemp-seed [presumably, flowers], and, creeping under the felt coverings, throw it upon the red-hot stones; immediately it smokes, and gives out such a vapour as no Grecian vapour-bath can exceed; the Scyths, delighted, shout for joy." Classical Greeks and Romans were using cannabis, while in the Middle East, use spread throughout the Islamic empire to North Africa. Various forms of the drug cannabis exist, including extracts such as hashish and hash oil Medical cannabis (or medical marijuana) refers to the use of cannabis and its constituent cannabinoids, to treat disease or improve symptoms.
In 1545, cannabis spread to the western hemisphere where Spaniards imported it to Chile for its use as fiber. Cannabis is used to reduce nausea and vomiting during chemotherapy, to improve appetite in people with HIV/AIDS, and to treat chronic pain and muscle spasms.
An international team demonstrated that this material contained tetrahydrocannabinol, the psychoactive component of cannabis.
The cannabis was presumably employed by this culture as a medicinal or psychoactive agent, or an aid to divination.
