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 ...
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]
A drug combination chart designed for harm reduction by TripSit [1]. Polysubstance use or multisubstance use is the use of combinations of psychoactive substances with both legal and illegal substances.
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 ...
In dogs, the minimum lethal dose of THC is over 3000 mg/kg. [20] According to The Merck Index, [21] the LD 50 of THC (the dose which causes the death of 50% of individuals) is 1270 mg/kg for male rats and 730 mg/kg for female rats from oral consumption in sesame oil, and 42 mg/kg for rats from inhalation.

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]
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.
A 2000 study by the US NIST [6] examined 12 chemical spot tests and concluded that all the tests examined "may indicate a specific drug or class of drugs is in the sample, but the tests are not always specific for a single drug or [class]". The study also noted that "mace, nutmeg and tea reacted with the modified Duquenois–Levine [test]".
