how long does marijuana stay in your system for a pee test?

i have 3 weeks till get tested is that long enough its a very expensive detailed pee test.

 

You better hope so, the usual range is between 90 and 120 days.

My advice: Skip town!

 

^^ not true. 90 to 120 days is an exaggeration.


It is very possible to pass in 3 weeks. You best bet is to do a lot of running and excercise. Burning fat is the best thing you can do. Some say taking a little extra B-vitamins and Niacin helps, but there isn't any concrete evidence that this works. So stop smoking, exercise every single day, and there's a good chance you'll be ok.

 

Excellent advice. I once faced the same situation, and I did what you suggest. In fact, I was motivated to run farther than I had ever done before (6 miles). Also, drink lots of water every day. I passed.

 

It's as long as the search button. Sorry I could not resist.

As a general rule most people say it can be in your system for as long as 30 days.

 

Ah, the infamous piss test question. Well, disregard what instant gratification said, hes probably high. Pot will rarely stay in your piss for more than a month, and thats only if your a HEAVY smoker. I got constantly tested by my parents in high school, and I've had to go to two rehabs, which used very sensitive testing. So I know drug tests.

If you stop for 3 weeks, than that possibly could be enough time, but it depends. If your a once or twice a week smoker, than your fine, if you an every day smoker, your not. The detailed tests don't go that much further back than the do it yourself ones. They more just screw you over when your borderline.

In some situations, its good to just chug water. When you drink allot of water, your piss will be so diluted that your THC levels are WELL below the threshold. If the tests for work, than forget the water, because, they'll treat diluted piss like you tested positive. However, if the tests for probation, than I suggest getting a do it yourself test. Even if your barley possitve, you should CHUG the day of the probation test. If you just do that, than your PO will see its diluted, and just make you wait an hour. So what you should do is take a good amount of vitamin B12 (I think thats what it is), maybe 3 or 4x the normal dose, or you could eat allot of asparagus. Vitamin B12 makes undiluted urine look insanely yellow, but it makes diluted urine look like ordinary urine. Once the test is shipped off, your fine. They WILL know you diluted your piss, but since they cant prove why, you'll just have to take another test, but by then it will have been at least another week. Just don't do that more than once, or you will get in trouble. You can also use this method if you smoke rarely, and your po just happens to call you the day after you smoke.

 

Like I said in my post, vitamin b and niacin are used to make your piss more yellow if its diluted. Thats what your probably thinking of. It in no way makes you test negative.

 

true, but it is also believed (although i think it is an oversimplification and not entirely true) that niacin (and other vit. b's) helps burning energy. biochemically niacin helps burn energy. niacin is the key part of NAD, which is an electron acceptor and fuels the electron transport chain, and therefore the production of energy, during the burning of fats and sugars. in the end though, i think taking extra doesn't do much.

 

you guys are wrong i have taken so many piss tests it would make your head spin and niacin DOES work it has worked for me every time you just have to take like nine a day and drink a bunch of water and weed stays in your system for about a month

 

^ thats how you end up in the hospital with Niacin Toxicity...
