    THC, the main psychoactive component of cannabis, may only be detectable in saliva and oral fluid for 2–24 hours in most cases. [8] [9] The main metabolite excreted in the urine is 11-Nor-9-carboxy-THC, also known as THC-COOH. Most cannabis drug tests yield a positive result when the concentration of THC-COOH in urine exceeds 50 ng/mL. [10]

    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]

    en.wikipedia.org/wiki/Tetrahydrocannabinol

    The main metabolite in urine is the ester of glucuronic acid and 11-OH-THC and free THC-COOH. In the feces, mainly 11-OH-THC was detected. [36] Estimates of the elimination half-life of THC are variable. [22] THC was reported to have a fast initial half-life of 6 minutes and a long terminal half-life of 22 hours in a population pharmacokinetic ...

  5. Tetrahydrocannabinolic acid - Wikipedia

    en.wikipedia.org/wiki/Tetrahydrocannabinolic_acid

    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.

  6. Cannabis concentrate - Wikipedia

    en.wikipedia.org/wiki/Cannabis_concentrate

    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.

  8. Tetrahydrocannabutol - Wikipedia

    en.wikipedia.org/wiki/Tetrahydrocannabutol

    Δ 9-Tetrahydrocannabutol (tetrahydrocannabinol-C4, THC-C4, Δ 9-THCB, (C4)-Δ 9-THC, butyl-THC) is a phytocannabinoid found in cannabis that is a homologue of tetrahydrocannabinol (THC), the main active component of Cannabis. [1] Structurally, they are only different by the pentyl side chain being replaced by a butyl side chain.
