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.
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.
Cannabis sativa is an annual herbaceous flowering plant. The species was first classified by Carl Linnaeus in 1753. The specific epithet sativa means 'cultivated'. Indigenous to Eastern Asia, the plant is now of cosmopolitan distribution due to widespread cultivation. It has been cultivated throughout recorded history and used as a source of industrial fiber, seed oil, food, and medicine. It is also used as a recreational drug and for religious and spiritual purposes.
Cultivation of cannabis is the production of cannabis infructescences. Cultivation techniques for other purposes differ.
Cannabis ruderalis is a variety, subspecies, or species of Cannabis native to Central and Eastern Europe and Russia. It contains a relatively low quantity of psychoactive compound tetrahydrocannabinol (THC). Some scholars accept C. ruderalis as its own species due to its unique traits and phenotypes which distinguish it from C. indica and C. sativa; others debate whether ruderalis is a subdivision under C. sativa.
Cannabis flower essential oil, also known as hemp essential oil, is an essential oil obtained by steam distillation from the flowers, panicles, stem, and upper leaves of the hemp plant. Hemp essential oil is distinct from hemp seed oil and hash oil: the former is a vegetable oil that is cold-pressed from the seeds of low-THC varieties of hemp, the latter is a THC-rich extract of dried female hemp flowers (marijuana) or resin (hashish).
The Hunter Valley cannabis outbreak was an infestation of Cannabis sativa in the Hunter Valley in New South Wales, Australia. At its peak, the infestation covered about 30 square kilometres (12 sq mi). It took nine years for the Government of New South Wales to eradicate it.
Cannabis strains are either pure or hybrid varieties of the plant genus Cannabis, which encompasses the species C. sativa, C. indica, and C. ruderalis.
The Industrial Hemp Farming Act of 2009, introduced during the 111th United States Congress by House Republican Ron Paul of Texas) and House Democrat Barney Frank of Massachusetts) on April 2, 2009, sought to clarify the differences between marijuana and industrial hemp as well as repeal federal laws that prohibit cultivation of industrial, but only for research facilities of higher education from conducting research. Industrial hemp is the non-psychoactive, low-THC, oil-seed and fibers varieties of, predominantly, the cannabis sativa plant. Hemp is a sustainable resource that can be used to create thousands of different products including fuel, fabrics, paper, household products, and food and has been used for hundreds of centuries by civilizations around the world. If H.R.1866 passes American farmers will be permitted to compete in global hemp markets. On March 10, 2009, both Paul and Frank wrote a letter to their Congressional colleagues urging them to support the legislation. This bill was previously introduced in 2005 under the title of Industrial Hemp Farming Act of 2005.
Autoflowering cannabis or day neutral cannabis varieties automatically switch from vegetative growth to the flowering stage based on age, as opposed to the ratio of light to dark hours required with photoperiod dependent/short-day strains. Many autoflowering varieties are ready to harvest in less than 10 weeks from seed. Dwarf varieties can have short stature while still giving decent harvests.
Hemp juice is a beverage derived from industrial hemp, made from the result of pressing the Cannabis sativa plant. The juice is obtained through a large-scale industrial cold-pressing procedure using the upper parts of the hemp plant as well as the leaves. This procedure distinguishes hemp juice from other hemp products such as hemp oil, hemp sprouts or hemp milk, which are obtained through the seeds of the hemp plant.
Hemp protein is a plant-derived protein from the cannabis plant and is isolated from hemp seeds.
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 is illegal in Russia. Possession of up to 6 grams is an administrative offense, punishable by a fine or detention of 15 days. Possession of larger amounts is a criminal offense.
Cannabis in Alberta became legalized on October 17, 2018 following the coming into force of federal Bill C-45. Production, distribution and consumption of cannabis had been prohibited in Canada since 1923. While some other provinces distribute cannabis through publicly owned retail monopolies, Alberta allows private companies to sell cannabis at licensed retail storefronts and online. Private retailers must purchase cannabis from the provincial wholesaler, the AGLC. Originally, the Alberta government was the sole entity permitted to retail cannabis online within the province but as of March 8, 2022, private retailers are permitted to do so and the province has since exited the retail business.
Hemp paper is paper varieties consisting exclusively or to a large extent from pulp obtained from fibers of industrial hemp. The products are mainly specialty papers such as cigarette paper, banknotes and technical filter papers. Compared to wood pulp, hemp pulp offers a four to five times longer fibre, a significantly lower lignin fraction as well as a higher tear resistance and tensile strength. Because the paper industry's processes have been optimized for wood as the feedstock, production costs currently are much higher than for paper from wood.
Hemp in the United States is a legal crop. It was legal in the 18th and 19th centuries, then production was effectively banned in the mid-20th century, and 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.
