Hello, : Hello, the more important issue is how much exposure you have. If you used a small amount once, it's metabolites will likely be out of your system within a week. If you are a chronic heavy user, it could take a couple of months for the metabolites to clear.

Depends: On how much marijuana you were smoking, how often. Although you are thin, thc still builds up in subcutaneous and tissue fat, and may last for several weeks as metabolites in urine detected by drug testing. If you smoked only occasionally and in modest amounts, the test will be negative after 2-3 days. You can buy your own urine test and see for yourself. Nothing 'detoxes' or makes it exit faster.
