For chronic users, it goes up to 13 days due to accumulation in fat stores. Higher doses or stronger products extend detection times. THC metabolites deposit into hair strands over time. Urine testing is the most common method for detecting cannabis use. It is then metabolized in the liver into 11-hydroxy-THC (11-OH-THC), the active form, and 11-nor-9-carboxy-THC (THC-COOH), the inactive metabolite stored in fat cells and gradually released (and used in most drug tests).

How long can THC be detected in the body for regular and occasional users?

After entering and circulating through the body, some THC will reach hair follicles through small blood vessels where small amounts are deposited into the growing hair. With these tests, scientists were able to estimate the initial half-life of THC is around 1.3 days for frequent and infrequent users. THC can stay in your system for several weeks, but how long exactly depends on a range of factors such as frequency of use, your individual metabolic rate, and body fat percentage. Your body could have metabolites present anywhere from 45 to 80 days.
This can delay the onset of effects by 30 minutes to 2 hours or more. When you eat marijuana in the form of edibles, it takes longer for THC to be absorbed because it has to go through your digestive system first.
