Although the chemical formula for THC (C 21 H 30 O 2) describes multiple isomers, [10] the term THC usually refers to the delta-9-THC isomer with chemical name (−)-trans-Δ 9-tetrahydrocannabinol. It is a colorless oil.
Cannabis (/ ˈ k æ n ə b ɪ s /), [2] commonly known as marijuana (/ ˌ m æ r ə ˈ w ɑː n ə /), [3] weed, and pot, among other names, is a non-chemically uniform drug from the Cannabis plant. Native to Central or South Asia, cannabis has been used as a drug for both recreational and entheogenic purposes and in various traditional ...
Δ-8-tetrahydrocannabinol (delta-8-THC, [a] Δ 8-THC) is a psychoactive cannabinoid found in the cannabis plant. [1] It is an isomer of delta-9-tetrahydrocannabinol (delta-9-THC, Δ 9-THC), the compound commonly known as THC, with which it co-occurs in hemp; natural quantities of ∆ 8-THC found in hemp are low.
Cannabis plants produce a unique family of terpeno-phenolic compounds called cannabinoids, some of which produce the "high" which may be experienced from consuming marijuana. There are 483 identifiable chemical constituents known to exist in the cannabis plant, [53] and at least 85 different cannabinoids have been isolated from the plant. [54]
Tetrahydrocannabinolic acid (THCA, 2-COOH-THC; conjugate base tetrahydrocannabinolate) is a precursor of tetrahydrocannabinol (THC), an active component of cannabis. [1]THCA is found in variable quantities in fresh, undried cannabis, but is progressively decarboxylated to THC with drying, and especially under intense heating such as when cannabis is smoked or cooked into cannabis edibles.
Dronabinol (brand names Marinol and Syndros) is a delta-9-THC containing drug for treating HIV/AIDS-induced anorexia and chemotherapy-induced nausea and vomiting. [58] The CBD drug Epidiolex has been approved by the Food and Drug Administration for treatment of two rare and severe forms of epilepsy, [59] Dravet and Lennox-Gastaut syndromes. [60]
Differences in the chemical composition of Cannabis varieties may produce different effects in humans. Synthetic THC, called dronabinol , does not contain cannabidiol (CBD), cannabinol (CBN), or other cannabinoids, which is one reason why its pharmacological effects may differ significantly from those of natural Cannabis preparations.
Marijuana, or marihuana, is a name for the cannabis plant, and more specifically, a drug preparation from it. [ 1 ] [ 2 ] [ 3 ] "Marijuana" as a term varies in usage, definition and legal application around the world. [ 4 ]
