how long does it take after smoking marijuana before you can pass a drug test????

i've heard 2 weeks before, but i've also heard 30 days. and is there any way other than buying detox that you can speed up getting it out of your body?

id say drink a ton of liquids like water and tons of sleep.plus dont be round 2nd hand smoke.its supposedly 30 days max but a friend of mine who was on it in quite high doses and didnt eat/sleep too well when detoxing was still testing positive for like 2 weeks after that for the drug testers/rehab/parole thought she was still smoking.

better drugs to do to detox fast from is like crack which takes 3 days max-not that i condone crack smoking or think crack cocaine is a good thing its not imho.

yep, 30 days..............flush your system out, but that's still no guarantee.....you can also buy some sort of detox tea at the health food store and it's not that expensive........good luck........
