How long does it take for one to be cleared of drugs ?
For weed, it's generally 30 days. THC sticks to the fat cells in your body, so this can either be a shorter amount of time or significantly longer, depending on your body. If you are a big water drinker, you're in even better shape because if you keep the body irrigated, the flow of water removes a great deal of toxins in the body that those tests will pick up.
Reply:I've heard that it takes about 1 month for the weed to get out of your system. I'm assuming that you will be taking a urine exam and if you've smoked recently it will come out positive. I know some people drink those special drinks they sell in "alternative stores" that are supposed to clean your system and they do work. They are expensive though about 60 dollars.
Reply:well there is a couple of factors that you have to keep in mind for one





the amount of weed you smoke


and also the percentage of fat in your body because thc sticks to fat cells





basicly if your skinny and you only smoke once or twice a week it will be out in less than 2 weeks





if your body fat percentage is significantly high it might take you twice as long
Reply:Depends on what type of drug test your taking. Hair sample, blood or urine. Also are you using something to clear out your system.
