Depends on how much you smoke and what drug.
yes you can if you know how to clean correctly.
If you mean a drug test, that depends on how often you smoke. Every day = 90 days to be clean. A few times a month = 30 days.
no
stop smoking.... lol
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.
It all depends on your metabolism but, the chances that you are clean by now are great. Buy a cheapo drug test from Walgreen's drug store and test yourself to be safe. I think they are 15 bucks.

It is possible that a drug test can be passed for opiates and cocaine after 10 days clean.
