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.
Medical cannabis, or medical marijuana (MMJ), is cannabis and cannabinoids that are prescribed by physicians for their patients. The use of cannabis as medicine has not been rigorously tested due to production and governmental restrictions, resulting in limited clinical research to define the safety and efficacy of using cannabis to treat diseases.
This article presents common techniques and facts regarding the cultivation of cannabis, primarily for the production and consumption of its infructescences. Cultivation techniques for other purposes differ.
Cannabis indica is an annual plant species in the family Cannabaceae indigenous to the Hindu Kush mountains of Southern Asia. The plant produces large amounts of tetrahydrocannabinol (THC) and tetrahydrocannabivarin (THCV) with levels up to 53.7% of total cannabinoid. It is now widely grown in China, India, Nepal, Thailand, Afghanistan, and Pakistan, as well as southern and western Africa, and is cultivated for purposes including hashish in India. The high concentrations of THC or THCV provide euphoric effects making it popular for use both as a recreational drug, alternative medicine, and a clinical research drug.
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 tea is a cannabis-infused drink prepared by steeping various parts of the cannabis plant in hot or cold water. Cannabis tea is commonly recognized as an alternative form of preparation and consumption of the cannabis plant, more popularly known as marijuana, pot, or weed. This plant has long been recognized as an herbal medicine employed by health professionals worldwide to ease symptoms of disease, as well as a psychoactive drug used recreationally and in spiritual traditions. Though less commonly practiced than popular methods like smoking or consuming edibles, drinking cannabis tea can produce comparable physical and mental therapeutic effects. Such effects are largely attributed to the THC and CBD content of the tea, levels of which are drastically dependent on individual preparation techniques involving volume, amount of cannabis, and boiling time. Also in common with these administration forms of cannabis is the heating component performed before usage. Due to the rather uncommon nature of this particular practice of cannabis consumption in modern times as well as the legality of cannabis throughout the World, the research available on the composition of cannabis tea is limited and based broadly around what is known of cannabis as it exists botanically.
The High TimesCannabis Cup is a cannabis festival sponsored by High Times magazine. The event features judges from around the world who sample and vote for their favorite marijuana varieties, with cups (trophies) being awarded to the overall winner in the cannabis variety competition. Since 1997, the Cannabis Cup festival has hosted induction ceremonies for the Counterculture Hall of Fame.
Cannabis strains are either pure or hybrid varieties of the plant genus Cannabis, which encompasses the species C. sativa, C. indica, and C. ruderalis.
In Colorado, cannabis has been legal for medical use since 2000 and for recreational use since late 2012. On November 7, 2000, 54% of Colorado voters approved Amendment 20, which amended the State Constitution to allow the use of marijuana in the state for approved patients with written medical consent. Under this law, patients may possess up to 2 ounces (57 g) of medical marijuana and may cultivate no more than six marijuana plants. Patients who were caught with more than this in their possession could argue "affirmative defense of medical necessity" but were not protected under state law with the rights of those who stayed within the guidelines set forth by the state. The Colorado Amendment 64, which was passed by voters on November 6, 2012, led to recreational legalization in December 2012 and state-licensed retail sales in January 2014. The policy has led to cannabis tourism. There are two sets of policies in Colorado relating to cannabis use: those for medicinal cannabis and for recreational drug use along with a third set of rules governing hemp.
The High TimesMedical Cannabis Cup is an annual event celebrating medical marijuana. The first Medical Cannabis Cup took place in San Francisco, California, on June 19–20, 2010.
Nevil Martin Schoenmakers was an Australian-born cannabis breeder known for founding the first cannabis seedbank, which was called "The Seed Bank of Holland", in the early 1980s in the Netherlands. This was also the first seed company to advertise directly to the public in High Times magazine.
Charlotte's Web is a brand of high-cannabidiol (CBD), low-tetrahydrocannabinol (THC) products derived from industrial hemp and marketed as dietary supplements and cosmetics under federal law of the United States. It is produced by Charlotte's Web, Inc. in Colorado. Hemp-derived products do not induce the psychoactive "high" typically associated with recreational marijuana strains that are high in THC. Charlotte's Web hemp-derived products contain less than 0.3% THC.
The entourage effect is a hypothesis that cannabis compounds other than tetrahydrocannabinol (THC) act synergistically with it to modulate the overall psychoactive effects of the plant.
