How can you pass a drug test if you smoke marijuana?

30 days. but you can cut it down, by drinking water, cranberry juice, and excercising, and sitting (or anything that makes you sweat.) Try to eat wel, because THC stores in fat cells.

STOP....Smoking for 30 days, then take the drug test. There are no easy ways out of this. Trust me my son has done everything and bought everything to avoid failing this test. So far every quick fix he has bought and drank or took has failed. There was one thing..It's called a weezanator, but then you have to get someone else that is drug free to pee for you, while you carry the pee next to your leg to keep it body temp. And even then it broke loose while he was with his probation officer. But good luck and if there is really anything out their please let us know.
