Thread: How many days does it take before marijuana/THC will not show up in a urine test?

Let's say, for example, a teenager smokes a gram of marijuana on a Monday night at 6pm. How long will the teen have to wait for a urine test to show up as "negative" and how much water should that teenager drink in order to speed up the process/flush out their system? Thanks!

3 weeks

3 weeks to 30 days

about a month, with lots of water.
2 weeks if you drink a shi*t ton of water,
but thats not a promise.

*exercise may help, sweat some of it out.

My brother mixed a little vinegar and water together and drank it . I also heard that there are products at vitamin world and gnc that can assist with getting rid of it. If nothing else, 30 days until it naturally passes.

If you are an everyday smoker, at least a month. If you only used 1 night you are probably OK in a week or so. If it was only 1 night I wouldn't worry about drinking extra water, although if you do that on the day of test to dilute your urine you should probably take a B-complex vitamin as that will help give your urine a yellow color and make it less obvious you are diluting it.

It will take like 30 days.unless your drink a few gallons of water each day or you go to a smoke shop and buy detox cleanse.it's about 20 bucks.but you must follow the detox instructions or it won't work

hahaha do you have to do a test soon? I've heard that it takes three months for it to completely clear from your body and I don't think drinking copious amounts of water will make any difference. although it improves your complexion.

if you do have to do a test for some reason and don't want your parents to find out that you smoke weed; you could just say you were at a party/music festival and a lot of people around you were smoking weed.

The detox time is usually from 3-30 days but can be as long as 90 days
But if you drink ALLOT of cranberry juice or water ( About 5-20 Gallons A Day ) then it should be about 2 weeks most likely less

Happy Holidays!

Answer mine please & thanks

Thc is kenetic one so the metabolism is dependent on the available load. The less on board the less it metabolizes. Usually 6 weeks is what the leagaly acceptable urine test can find. There are test we use in research that can go back 20 weeks. If you just used a minor amount one time, 2-3 weeks should be fine for urine.
