If you are talking about marijuana, yes it is possible, but also very possible you will fail as well. Depends on how much you smoked, your height and weight, and your body's metabolism. Drink lots of water up until the day of the test. Don't drink too much before the test or it will be diluted and considered a positive test.
stop smoking.... lol
friends 2
yes you can if you know how to clean correctly.
no
Depends on how much you smoke and what drug.
After 41 days, yes, you should be clean, unless you were smoking an absolutely obscene amount of marijuana every day. For people who smoke every day, it takes about 2 to 6 weeks (or a month on average) before you can give a clean urine sample. If you are already clean, and then you smoke just once, it will be out of your urine in 3 to 4 days. See the Related Question below.
Individuals who use marijuana may develop cancer, breathing problems, and it destroys your brain cells. So no, technically you won't be alright if you smoke it once and have twenty days to be clean. :)
It is possible that a drug test can be passed for opiates and cocaine after 10 days clean.
