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]
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. [57] [58] [59] There is ongoing research to create devices capable of detecting THC in ...
11-COOH-THC is a Schedule 8 prohibited substance in Western Australia under the Poisons Standard (July 2016). [15] A schedule 8 substance is a controlled Drug – Substances which should be available for use but require restriction of manufacture, supply, distribution, possession and use to reduce abuse, misuse and physical or psychological dependence.
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]
For a substance to be considered legal hemp, it can’t contain more than 0.3% of Delta 9 THC by dry weight. That limit, said Phil Dixon, Jr., a cannabis-focused lawyer and the director of UNC ...
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.
These are achieved at lower doses, because many synthetic cannabinoids are more potent than marijuana, and users are often unaware of exactly what they are getting and how potent it is. [55] For example, Δ 9-THC has an EC 50 of 250 nM at CB 1 and 1157 nM at CB 2, whereas PB-22 has an EC 50 of 5.1 nM at CB 1 and 37 nM at CB 2. [8]
