About 3 months.
Answer
Marijuana normally takes between 2 and 6 weeks to leave your system. So, around a month is a safe bet. A month is also the answer I got from my doctor, who is an addiction specialist.
If its your first time it will not be in your system longer than a week. if you exercise and drink lots of water it will be out of your system in no time.
it usually takes about 90 days to clear your system.
You should be, normally it only takes 2-3 days to leave your system unless you are a regular user then it can take a month or so.
no.
If you only smoked once, no more than two weeks, depending on how much, it may be out of your system in a matter of days.
3 weeks to a month, I'm editing this answer.. If it is your first time ever smoking pot(which is what im guessing), then you should be fine in about a week. I've had it out of my system in 5 days before. Take it easy for a week, drink water and exercise.
Yes it is in your system for up to 1 year.
There is no magic way to "clear your system" of marijuana. As long as you don't use again before the test, you'll probably be okay.
If it's the first time you've smoked in a month, 15-30 days.
They are measures of mass: the first in a near-obsolete system and the second in the International system.
If you are having a urine or blood test then Cotinine- the breakdown product of nicotine that they test for you should be clear 4 days after your last smoke. Nicotine itself should be out of your system within hours broken down of course into Cotinine.
if it was the first time you smoked then it will be another 4-5 days til you pass a urine, blood, and hair test. if you've smoked more than that go to this website http://www.detoks.com/page_virtual-drug-test.html this will give you an estimate of when you'll be clean
