Cannabis 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, all three may be treated as subspecies of C. sativa, or C. sativa may be accepted as a single undivided species. The genus is widely accepted as being indigenous to and originating from Asia.
The Marihuana Tax Act of 1937, Pub. L.Tooltip Public Law 75–238, 50 Stat. 551, enacted August 2, 1937, was a United States Act that placed a tax on the sale of cannabis. The H.R. 6385 act was drafted by Harry Anslinger and introduced by Rep. Robert L. Doughton of North Carolina, on April 14, 1937. The Seventy-fifth United States Congress held hearings on April 27, 28, 29th, 30th, and May 4, 1937. Upon the congressional hearings confirmation, the H.R. 6385 act was redrafted as H.R. 6906 and introduced with House Report 792. The Act is referred to, using the modern spelling, as the 1937 Marijuana Tax Act. It was overturned in 1969 in Leary v. United States, and was repealed by Congress the next year.
Jack Herer, sometimes called the "Emperor of Hemp", was an American cannabis rights activist and the author of the 1985 book The Emperor Wears No Clothes. Herer founded and served as the director of the organization Help End Marijuana Prohibition (HEMP).
Hemp oil is oil obtained by pressing hemp seeds. Cold pressed, unrefined hemp oil is dark to clear light green in color, with a nutty flavor. The darker the color, the grassier the flavour. It should not be confused with hash oil, a tetrahydrocannabinol-containing oil made from the Cannabis flower.
Hemp, or industrial hemp, is a plant in the botanical class of Cannabis sativa cultivars grown specifically for industrial and consumable use. It can be used to make a wide range of products. Along with bamboo, hemp is among the fastest growing plants on Earth. It was also one of the first plants to be spun into usable fiber 50,000 years ago. It can be refined into a variety of commercial items, including paper, rope, textiles, clothing, biodegradable plastics, paint, insulation, biofuel, food, and animal feed.
Hemp or industrial hemp is a strain of the Cannabis sativa plant grown specifically for the industrial uses of its derived products.
Louis Gatewood Galbraith was an American author and attorney from the U.S. Commonwealth of Kentucky. He was a five-time political candidate for governor of Kentucky.
The Hemp Industries Association (HIA) is a non-profit trade group representing hemp companies, researchers and supporters in the United States and Canada. The group petitions for fair and equal treatment of industrial hemp. Since 1994, the HIA has been dedicated to education, industry development, and the accelerated expansion of hemp world market supply and demand.
Cannabis in India has been known to be used at least as early as 2000 BCE. In Indian society, common terms for cannabis preparations include charas (resin), ganja (flower), and bhang, with Indian drinks such as bhang lassi and bhang thandai made from bhang being one of the most common legal uses.
Cannabis in Kentucky is illegal for recreational use, and legal for medical use under executive order, with full medical legalization statute taking effect in 2025. Non-psychoactive CBD oil is also legal in the state, and Kentucky has a history of cultivating industrial hemp for fiber since 1775.
Kentucky was the greatest producer of hemp in the United States during the 19th and 20th centuries, when it was the source of three fourths of U.S. hemp fiber. Production started to decline after World War I due to the rise of tobacco as the cash crop in Kentucky and the foreign competition of hemp fibers and finished products. In 1970, federal policies virtually banned the production of industrial hemp during the war on drugs saying all Cannabis sativa is a Schedule I controlled substance. Federal law under the Agricultural Act of 2014 allowed research back into hemp. Kentucky began production again with 33 acres in 2014. As of the 2016 harvest season, only two U.S. states other than Kentucky had over 100 acres (40 ha) in hemp production: Colorado and Tennessee. The first 500-acre commercial crop was planted in Harrison County in 2017, and research permits were issued for over 12,000 acres (4,900 ha) that year. The 2016 documentary Harvesting Liberty concerns the 21st century Kentucky hemp industry.
Cannabis in Italy is currently legal for medical and industrial uses, although it is strictly regulated, while it is decriminalized for recreational uses. In particular, the possession of small amounts of marijuana for personal use is a civil infraction. The possible sanctions for possession vary from the issuing of a diffida to first offenders, that is an injunction not to use the drug again; to the temporary suspension of certain personal documents for repeat offenders. Conversely, the unauthorized sale of cannabis-related products is illegal and punishable with imprisonment, as is the unlicensed cultivation of cannabis, although recent court cases have effectively established the legality of cultivating small amounts of cannabis for exclusively personal use. The licensed cultivation of cannabis for medical and industrial purposes requires the use of certified seeds; however, there is no need for authorization to plant certified seeds with minimal levels of psychoactive compounds.
Cannabis has been cultivated in Japan since the Jōmon period of Japanese prehistory approximately six to ten thousand years ago. As one of the earliest cultivated plants in Japan, cannabis hemp was an important source of plant fiber used to produce clothing, cordage, and items for Shinto rituals, among numerous other uses. Hemp remained ubiquitous for its fabric and as a foodstuff for much of Japanese history, before cotton emerged as the country's primary fiber crop amid industrialization during the Meiji period. Following the conclusion of the Second World War and subsequent occupation of Japan, a prohibition on cannabis possession and production was enacted with the passing of the Cannabis Control Law.
Cannabis in Ukraine is legal for medical purposes.
Cannabis has served as an entheogen—a chemical substance used in religious or spiritual contexts—in the Indian subcontinent since the Vedic period dating back to approximately 1500 BCE, but perhaps as far back as 2000 BCE. It was introduced to the New World by the Spaniards in 1530-1545.
The history of cannabis and its usage by humans dates back to at least the third millennium BC in written history, and possibly as far back as the Pre-Pottery Neolithic B based on archaeological evidence. For millennia, the plant has been valued for its use for fiber and rope, as food and medicine, and for its psychoactive properties for religious and recreational use.
The following outline is provided as an overview of and topical guide to the plant Cannabis sativa and its relatives Cannabis indica and Cannabis ruderalis, the drug cannabis (drug) and the industrial product hemp.
Hemp in the United States was a legal crop in the 18th and 19th centuries. Production was effectively banned in the mid-20th century, but it returned as a legal crop in the 21st century. By 2019, the United States had become the world's third largest producer of hemp, behind China and Canada.
Arlington Experimental Farm was a former federal agricultural research farm in Alexandria, Virginia that opened in 1900. It was established by an Act of Congress, moving the Department of Agriculture's main research from the National Mall to Arlington. It grew hemp beginning in 1903, or 1914. In 1928, it was the largest United States Department of Agriculture experiment station in the Washington, D.C. area. USDA researcher Vera Charles also worked at the station, collecting Cannabis seeds from across America and studying pests and pathogens that could diminish hemp crop productivity. Cultivars developed at Arlington include Arlington, Chington, Ferramington, Kymington and Arlington; Chington and Kymington were adopted "extensively" by seed farmers producing hemp in Kentucky. The seeds were probably destroyed by the government in the 1980s.
