How long does it take for weed to get out of your system for a physical/urine test? Does drinking a lot of water help it get out faster?

I've heard 14-30 days. You can take niacin to get it out of your system faster, but keep in mind that a lot of places test for an excess of niacin in your system.

Also, a good way to test negative for drugs on a drug test is simply DON'T DO THEM. I know I know, obvious!

Weed, THC is fat soluble. Depending on how much you smoke, and how much fat is on your body I've heard it take up to a couple of years of abstinence.

I think a couple of years is a bit much. I've test negative a month after smoking and I'm 30 pounds overweight.

Marijuana can take up to about 30 days to get out of your system. Usually it only takes 30 days for a heavy smoker. Water will not get marijuana out of your system but it will dillute your urine day of test helping your chances but no guarantees. There is a product called terminader gold that works wonders. It will take toxins out of your system with only staying clean for 24-36 hours. My friend buys it every week to pass his probation tests. He's been doing it for close to a year now and never failed one. It costs about $40

Wow, imagine if he didn't smoke and didn't buy that terminader gold stuff... he'd save about $200 a month.

Including the marijuana he would probably save more than that. I have urged him to just quit but he won't do it. He says lots of people spend that much money on beer and since he doesn't drink it is justified. Whatever, he's not hurting anyone so it doesn't bother me in the least.
