THC and its 11-OH-THC and THC-COOH metabolites can be detected and quantified in blood, urine, hair, oral fluid or sweat using a combination of immunoassay and chromatographic techniques as part of a drug use testing program or in a forensic investigation. [58] [59] [60] There is ongoing research to create devices capable of detecting THC in ...
Cannabis concentrate, also called marijuana concentrate, marijuana extract, or cannabis extract, is a tetrahydrocannabinol (THC) and/or cannabidiol (CBD) concentrated mass. Cannabis concentrates contain high THC levels that range from 40% to over 90%, [ 1 ] [ 2 ] stronger in THC content than high-grade marijuana, which normally measures around ...
Cannabinoids (/ k ə ˈ n æ b ə n ɔɪ d z ˌ ˈ k æ n ə b ə n ɔɪ d z /) are compounds found in the cannabis plant or synthetic compounds that can interact with the endocannabinoid system. [1] [2] The most notable cannabinoid is the phytocannabinoid tetrahydrocannabinol (THC) (Delta-9-THC), the primary intoxicating compound in cannabis.
Despite the CBD and THC having the same molecular weight, multiple analytical methods are able to differentiate them. [11] "on the recovery of both THC (86.7−90.0%) and CBD (92.3−95.6%). The slightly lower recovery of THC can be explained by the fact that THC is less polar than CBD and more likely to remain in the nonpolar sunflower oil." [11]
Cannabinoid absorption is dependent on its route of administration. Inhaled and vaporized THC have similar absorption profiles to smoked THC, with a bioavailability ranging from 10 to 35%. Oral administration has the lowest bioavailability of approximately 6%, variable absorption depending on the vehicle used, and the longest time to peak ...
CBD shares a precursor with THC and is the main cannabinoid in CBD-dominant Cannabis strains. CBD has been shown to play a role in preventing the short-term memory loss associated with THC. [29] There is tentative evidence that CBD has an anti-psychotic effect, but research in this area is limited. [30] [24]
Like Δ 9-THC, 11-hydroxy-THC is a partial agonist at the cannabinoid receptor CB 1, but with significantly higher binding affinity (K i = 0.37 nM compared to Δ 9-THC K i = 35 nM). [7] With respect to cAMP inhibition at CB 1 it displays a similar efficacy to that of Δ 9 -THC (EC 50 = 11 nM vs. EC 50 = 5.2 nM, respectively), but a lower ...
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.
