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]

[23] [33] THC is detectable within seconds with inhalation and peak levels of THC occur after 3 to 10 minutes. [3] [33] Smoking or inhaling THC results in greater blood levels of THC and its metabolites and a much faster onset of action than oral administration of THC.
Then, THC levels drop rapidly to less than 2 nanograms per milliliter of blood after about four hour. It takes around eight hours to reach similarly low concentrations of THC after taking an edible.
