Depends on the type: of test for THC or its metabolites, body fat %age (it's stored in fat), duration & frequency of use, size & meatabolism of user & cut-off point for + result. Infrequent use, up to 5-7 days, heavy use up to 15-21 days , chronic or obese users, 30 days or more, depending on cut-off of 50 nanograms/mL or 20 ng/mL. Metabolites have a much longer detection time.
