It might be out of your system by the time of your test. Recent studies are now saying Marijuanna detection times are 2-3 days for the infrequent user and around 10 for a chronic user. Obiously size, weight, metabolism, diet, and exercise play a role in this. If you stay on top of it by exercising, eating well, and hitting the sauna a couple times I'm confident you'll pass
thatubbyducky Reviewed by thatubbyducky on . Help Please: 19 days to Detox!!!!!! I'm currently on probation and have a drug test in about 20 days. I've stopped smoking and just looking for some advice to pass my test on the 13th. I have to pass this and it's sent to a lab so theirs not really a clear way around it. I'm thinking i'm just going to drink tons of water and run a mile or so every day and take small amounts of niacin regularly. Prior to this i smoked heavily probably about 1.5 grams a day. Please post with any advice, any help is appreciated. Thanks. Rating: 5
