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 ...
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]
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.
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.
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.
In the US, "industrial hemp" is classified by the federal government as cannabis containing no more than 0.3% THC by dry weight. This classification was established in the 2018 Farm Bill and was refined to include hemp-sourced extracts, cannabinoids, and derivatives in the definition of hemp.
Demand is high for pharmaceutical grade THC and other cannabinoids due to interest in their potential therapeutic use, but is stymied by legal regulations of C. sativa cultivation in many countries. [13] Direct chemical synthesis of THC is difficult due to high costs and low yields. [14]
