<i>Cannabis</i> Genus of flowering plants

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.

<span class="mw-page-title-main">Tetrahydrocannabinol</span> Chemical compound

Tetrahydrocannabinol (THC) is the principal psychoactive constituent of cannabis and one of at least 113 total cannabinoids identified on the plant. Although the chemical formula for THC (C21H30O2) describes multiple isomers, the term THC usually refers to the Delta-9-THC isomer with chemical name (−)-trans9-tetrahydrocannabinol. THC is a terpenoid found in cannabis and, like many pharmacologically active phytochemicals, it is assumed to be involved in the plant's evolutionary adaptation against insect predation, ultraviolet light, and environmental stress. THC was first discovered and isolated by Israeli chemist Raphael Mechoulam in Israel in 1964. It was found that, when smoked, THC is absorbed into the bloodstream and travels to the brain, attaching itself to endocannabinoid receptors located in the cerebral cortex, cerebellum, and basal ganglia. These are the parts of the brain responsible for thinking, memory, pleasure, coordination and movement.

<span class="mw-page-title-main">Effects of cannabis</span> Effects resulting from the use of cannabis

The effects of cannabis are caused by chemical compounds in the cannabis plant, including 113 different cannabinoids such as tetrahydrocannabinol (THC) and 120 terpenes, which allow its drug to have various psychological and physiological effects on the human body. Different plants of the genus Cannabis contain different and often unpredictable concentrations of THC and other cannabinoids and hundreds of other molecules that have a pharmacological effect, so that the final net effect cannot reliably be foreseen.

<span class="mw-page-title-main">Medical cannabis</span> Marijuana used medicinally

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.

<span class="mw-page-title-main">Cannabinoid</span> Compounds found in cannabis

Cannabinoids are several structural classes of compounds found in the cannabis plant primarily and most animal organisms or as synthetic compounds. The most notable cannabinoid is the phytocannabinoid tetrahydrocannabinol (THC) (delta-9-THC), the primary psychoactive compound in cannabis. Cannabidiol (CBD) is also a major constituent of temperate cannabis plants and a minor constituent in tropical varieties. At least 113 distinct phytocannabinoids have been isolated from cannabis, although only four have been demonstrated to have a biogenetic origin. It was reported in 2020 that phytocannabinoids can be found in other plants such as rhododendron, licorice and liverwort, and earlier in Echinacea.

The terpenoids, also known as isoprenoids, are a class of naturally occurring organic chemicals derived from the 5-carbon compound isoprene and its derivatives called terpenes, diterpenes, etc. While sometimes used interchangeably with "terpenes", terpenoids contain additional functional groups, usually containing oxygen. When combined with the hydrocarbon terpenes, terpenoids comprise about 80,000 compounds. They are the largest class of plant secondary metabolites, representing about 60% of known natural products. Many terpenoids have substantial pharmacological bioactivity and are therefore of interest to medicinal chemists.

<i>Cannabis sativa</i> Plant species

Cannabis sativa is an annual herbaceous flowering plant indigenous to Eastern Asia, but now of cosmopolitan distribution due to widespread cultivation. It has been cultivated throughout recorded history, used as a source of industrial fiber, seed oil, food, recreation, religious and spiritual moods and medicine. Each part of the plant is harvested differently, depending on the purpose of its use. The species was first classified by Carl Linnaeus in 1753. The word sativa means "things that are cultivated."

<span class="mw-page-title-main">Cannabinol</span> Naturally-occurring cannabinoid

Cannabinol (CBN) is a mildly psychoactive cannabinoid that acts as a low affinity partial agonist at both CB1 and CB2 receptors. This activity at CB1 and CB2 receptors constitutes interaction of CBN with the endocannabinoid system (ECS).

<span class="mw-page-title-main">Cannabidiol</span> Phytocannabinoid discovered in 1940

Cannabidiol (CBD) is a phytocannabinoid discovered in 1940. It is one of 113 identified cannabinoids in cannabis plants, along with tetrahydrocannabinol (THC), and accounts for up to 40% of the plant's extract. As of 2019, clinical research on CBD included studies related to anxiety, cognition, movement disorders, and pain, but there is insufficient high-quality evidence that cannabidiol is effective for these conditions. Nevertheless, CBD is a herbal dietary supplement promoted with unproven claims of particular therapeutic effects. The global market size for CBD was predicted to exceed US$47 billion by 2028.

<span class="mw-page-title-main">Cannabis (drug)</span> Psychoactive drug from the cannabis plant

Cannabis, also known as marijuana among other names, is a psychoactive drug from the cannabis plant. Native to Central or South Asia, the cannabis plant has been used as a drug for both recreational and entheogenic purposes and in various traditional medicines for centuries. Tetrahydrocannabinol (THC) is the main psychoactive component of cannabis, which is one of the 483 known compounds in the plant, including at least 65 other cannabinoids, such as cannabidiol (CBD). Cannabis can be used by smoking, vaporizing, within food, or as an extract.

<span class="mw-page-title-main">Caryophyllene</span> Chemical compound

Caryophyllene, more formally (−)-β-caryophyllene,(BCP), is a natural bicyclic sesquiterpene that is a constituent of many essential oils, especially clove oil, the oil from the stems and flowers of Syzygium aromaticum (cloves), the essential oil of Cannabis sativa, rosemary, and hops. It is usually found as a mixture with isocaryophyllene (the cis double bond isomer) and α-humulene (obsolete name: α-caryophyllene), a ring-opened isomer. Caryophyllene is notable for having a cyclobutane ring, as well as a trans-double bond in a 9-membered ring, both rarities in nature.

<span class="mw-page-title-main">Cannabichromene</span> Chemical compound

Cannabichromene (CBC), also called cannabichrome, cannanbichromene, pentylcannabichromene or cannabinochromene, is an anti-inflammatory which may contribute to the pain-killing effect of cannabis. It is one of the hundreds of cannabinoids found in the Cannabis plant, and is therefore a phytocannabinoid. It bears structural similarity to the other natural cannabinoids, including tetrahydrocannabinol (THC), tetrahydrocannabivarin (THCV), cannabidiol (CBD), and cannabinol (CBN), among others. CBC and its derivatives are as abundant as cannabinols in cannabis. It is not scheduled by the Convention on Psychotropic Substances. It is more common in tropical cannabis varieties.

<i>Quercus infectoria</i> Species of oak tree

Quercus infectoria or the Aleppo oak is a species of oak well known for producing galls that have been traditionally used for centuries in Asia medicinally while also used in softening leather and in making black dye and ink.

<i>Quercus salicina</i> Species of oak tree

Quercus salicina is an oak species found in Japan, South Korea and Taiwan. It is placed in subgenus Cerris, section Cyclobalanopsis.

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.

<i>delta</i>-8-Tetrahydrocannabinol Psychoactive drug from hemp

Delta-8-tetrahydrocannabinol is a psychoactive cannabinoid found in the Cannabis plant. It is an isomer of delta-9-tetrahydrocannabinol, the compound commonly known as THC. ∆8-THC is under preliminary research for its biological properties.

<span class="mw-page-title-main">Delta-10-Tetrahydrocannabinol</span> Chemical compound

Delta-10-Tetrahydrocannabinol is a positional isomer of tetrahydrocannabinol, discovered in the 1980s. Two enantiomers have been reported in the literature, with the 9-methyl group in either the (R) or (S) conformation; of these, the (R) enantiomer appears to be the more active isomer as well as the double bond in the 10th position instead of the 9th maintaining about 30 to 40 percent the potency of delta-9-THC. Δ10-THC has rarely been reported as a trace component of natural cannabis, though it is thought to be a degradation product similar to cannabinol rather than being produced by the plant directly. However, it is found more commonly as an impurity in synthetic delta-8-THC produced from cannabidiol and can also be synthesized directly from delta-9-THC.

<span class="mw-page-title-main">Cannabicitran</span> Chemical compound

Cannabicitran (CBTC) is a phytocannabinoid first isolated in 1974 as a trace component of Cannabis sativa, Structurally related compounds can be found in some other plants. It is not psychoactive, but was found to reduce intraocular pressure in tests on rabbits, which may reflect agonist activity at the NAGly receptor that is known to be a target of many structurally related cannabinoids.

<span class="mw-page-title-main">Cannabigerovarin</span> Organic chemical compound

Cannabigerovarin (CBGV), the propyl homolog of cannabigerol (CBG), is a cannabinoid present in Cannabis. There is no observation related to the psychoactive or psychotropic effects of CBGV when consumed or inhaled. The possible benefits of cannabigerovarin in human bodies are painkilling and anti-inflammatory properties to treat conditions like fibromyalgia and arthritis, the treatment and improvement of the dry-skin syndrome, cancer treatment by reducing the growth of cancer cells in patients who have leukemia. According to the pain-relieving effects of this natural cannabinoid, it can be helpful to treat patients who were undergoing drug exposure like chemotherapy or radiation therapy. In addition, cannabigerol metabolism increases and has a better absorption from the body when paired with cannabigerovarin.

Cannabinoids are compounds found in the cannabis plant or synthetic compounds that can interact with the endocannabinoid system. The most notable cannabinoid is the phytocannabinoid tetrahydrocannabinol (THC) (Delta-9-THC), the primary intoxicating compound in cannabis. Cannabidiol (CBD) is another major constituent of some cannabis plants. At least 113 distinct cannabinoids have been isolated from cannabis.
