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 2022 study published in the Journal of Psychopharmacology found that participants given oral cannabis (the lab-grade alternative to an edible) showed low blood THC concentration at the height of ...
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.
Two main questions arise in the law surrounding driving after having ingested cannabis: (1) whether cannabis actually impairs driving ability, and (2) whether the common practice of testing for THC (the main psychoactive substance in cannabis) is a reliable means to measure impairment.

[64] Ingestion of edible cannabis products lead to a slower onset of effect than the inhalation of it because the THC travels to the liver first through the blood before it travels to the rest of the ...
