Phytocannabinoids

Cannabidiol (CBD) is a phytocannabinoid, one of 113 identified cannabinoids in Cannabis, along with tetrahydrocannabinol (THC), and accounts for up to 40% of the plant's extract. Medically, it is an anticonvulsant used to treat two rare forms of childhood epilepsy. It was discovered in 1940. Clinical research on CBD has included studies related to the treatment of anxiety, addiction, psychosis, movement disorders, and pain, but there is insufficient high-quality evidence that CBD is effective for these conditions. CBD is sold as a herbal dietary supplement and promoted with unproven claims of

Tetrahydrocannabinol (THC) is a cannabinoid found in cannabis. It 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 '(−)-trans-Δ9-tetrahydrocannabinol'. It is a colorless oil.

Cannabinol (CBN) is a mildly psychoactive phytocannabinoid that acts as a low affinity partial agonist at the CB1 and CB2 receptors of the endocannabinoid system (ECS).

Tetrahydrocannabivarin (THCV, THV, O-4394, GWP42004) is a homologue of tetrahydrocannabinol (THC) having a propyl (3-carbon) side chain instead of pentyl (5-carbon), making it non-psychoactive in lower doses. It has been shown to exhibit neuroprotective activity, appetite suppression, glycemic control and reduced side effects compared to THC, making it a potential treatment for management of obesity and diabetes. THCV was studied by Roger Adams as early as 1942.

Cannabigerol (CBG) is a non-psychoactive cannabinoid and minor constituent of cannabis. It is one of more than 120identified cannabinoids found in the plant genus Cannabis. The compound is the decarboxylated form of cannabigerolic acid (CBGA), the parent molecule from which other cannabinoids are biosynthesized.

Cannabichromene (CBC), also called cannabichrome, cannanbichromene, pentylcannabichromene or cannabinochromene, is a phytocannabinoid, one of the hundreds of cannabinoids found in the Cannabis plant. It bears structural similarity to the other natural cannabinoids, including tetrahydrocannabinol (THC), tetrahydrocannabivarin (THCV), cannabidiol (CBD), and cannabinol (CBN), among others. It is not scheduled by the Convention on Psychotropic Substances.

Cannabivarin (CBV), also known as cannabivarol, is considered a non-psychoactive cannabinoid — it does not produce the euphoric side effects found in THC. Minor amounts of CBV are found in the hemp plant Cannabis sativa. It is an analog of cannabinol (CBN) with the side chain shortened by two methylene bridges (). CBV is an oxidation product of tetrahydrocannabivarin (THCV, THV).

Cannabidivarin (CBDV, GWP42006) is a non-intoxicating psychoactive cannabinoid found in Cannabis. It is a homolog (chemistry) of cannabidiol (CBD), with the side-chain shortened by two methylene bridges (CH2 units).

Cannabicyclol (CBL) is a non-psychoactive cannabinoid found in Cannabis. CBL is a degradative product like cannabinol, with cannabichromene degrading into CBL through natural irradiation or under acid conditions.
