CBD heated to 175, [13] or 250–300 °C may partially be converted into THC. [14] Even at room temperature, trace amounts of THC can be formed as a contaminant in CBD stored for long periods in the presence of moisture and carbon dioxide in the air, with storage under inert gas required to maintain analytically pure CBD.
Cannabis flower is commonly consumed using a dry herb vaporizer. The cannabis may be heated in a chamber via indirect flame exposure or an electrical heating element, allowing users to inhale the resulting vapor. The temperatures reached are cooler than the combustion temperature of cannabis, which is around 230–315 °C (445–600 °F). [9]
At room temperature, cannabidiol is a colorless crystalline solid. [75] In strongly basic media and the presence of air, it is oxidized to cannabinodiol (CBND) and a quinone called HU-331. [76] Under acidic conditions it cyclizes to THC, [77] which also occurs during pyrolysis, [78] and during smoking.

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]
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 ...

Cannabinoid hyperemesis syndrome (CHS) is recurrent nausea, vomiting, and cramping abdominal pain that can occur due to prolonged, high-dose cannabis use.
