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 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]
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]
Stoners and scientists disagree on the answer. Some ask for a new system.
There is a slight increase in dose proportionality in terms of peak and area-under-the-curve levels of THC with increasing oral doses over a range of 2.5 to 10 mg. [22] A high-fat meal delays time to peak concentrations of oral THC by 4 hours on average and increases area-under-the-curve exposure by 2.9-fold, but peak concentrations are not ...
By 2016, 23 states had legalized medical cannabis. Additionally, a number of states, as far back as the 1960s, have decriminalized the possession of small quantities of cannabis for personal use. [8] By 2020, the majority of the U.S. population can purchase cannabis and cannabinoid products as easily as alcohol. [1]
Cannabis strains is a popular name to refer to plant varieties of the monospecific genus Cannabis sativa L.. They are either pure or hybrid varieties of the plant, which encompasses various sub-species C. sativa , C. indica , and C. ruderalis .
The Δ 9 isomer of THCP occurs naturally in cannabis, but in small amounts.A 2021 study reported the content of Δ 9-THCP ranging from 0.0023% to 0.0136% (w/w) (approximately 0.02–0.13 mg/g) without correlation to THC percentage in Δ 9-THC-dominant strains of cannabis; that study failed to detect THCP in CBD-dominant strains.
