Medical News Today says first-time smokers may have cannabis detected for “about 3 days,” while more consistent smokers at three to four times per week can have it detected for “5-7 days” afterward. Daily smokers can expect tests to detect weed for at least 30 days. This is drawn out to around one week for a more sensitive 20 ng/mL threshold. Hair tests tend to have the longest detection window, capable of registering the levels ofa non-intoxicating THC metabolite called 11-nor-delta9-caboxy-THC (THC-COOH) up to 90 days after cessation. Additionally, usage, as well as an individual’s unique biology make the calculation of a detection window (the number of days after ceasing usage that a drug test will continue to be positive) even more complex.
