How long does it take to get marijuana out of your system?

I've never heard of this method of the vinegar... What I know, it is that THC remains in your blood for a long time! Say to your friend that he has to stop smoking for at least 3 months, but it is better for 6 months... And, if he wants to be surely clean, he has not to stay in place with other people smoke, because also the passive smoke is a problem... I'm really sorry for him, that he can't smoke anymore if he doesn't want problems...

how long does it take to get mari out of your system......... I don't know because personally I never tried to get any of it out of my system. But I had a friend who tried it once and they had to drink a whole cup of vinegar to try to neutralize it's affect so that it would not show up positive. Tell ur friend to have fun drinking the vinegar, I heard that it really does work.... Happy mylotting.

it takes about 30 days to clear your system. You can drink a great amount of water to flush it out which works but then again...most probation officers know that trick.

if your a chronic user then it may take about 30 days but if he just smokes once or twice a week it should only be their for a few days :]
