According to the Columbia University Health Services website (see the Related Question below) THC (the psychoactive ingredient in marijuana) can remain in the body's organs and fatty tissues forever. Unlike most other drugs, THC is fat-soluble, and is stored in your fat cells, which is why drinking water does not help remove it from your system: fatty substances do not dissolve in water.
However, even though marijuana can stay in your system forever, it is not detectable in a drug test forever. For daily smokers, it usually takes 2 to 6 weeks, or a month on average, before you can give a clean urine sample.
An obese person who uses marijuana every day should probably assume that it will take 6, or maybe even 8 weeks, for their urine to be clean. An obese person who is an extremely heavy user (like, a quarter-ounce a day or more) might have to wait 3 months to be clean.
For occasional users -- people who use marijuana only once or twice a week or less -- the timeframe is shorter, more like 2 weeks to one month. So, occasional users who are obese should probably assume that it will take one month, maybe 6 weeks at the most.
For more detailed information, see the Related Question below.
Typically, it takes three weeks for the THC metabolite that gets tested for to get beneath the normal threshold of the testing machines (~50 ng/ml), and another 3 weeks to be completely clear for a long-time user. However, people have still tested positive 10 weeks after their last use.
Depends on how much you take, frequency, how pure is it, and how long you have been doing it. The chemical in the Marijuana which makes you high!! is what they detect something called THC. Some people had taken test two months after they smoked it an fail the test so I think is best to stop using it. You don't want to go to jail. Trying to beat the test is almost impossible :O)
It will take approximately 6 months of going smoke free before your blood is free of measurable THC.
6 MONTHS
About 1 month.
for about a hour
It depends on how often you consume marijuana, your weight, and other factors. The marijuana will be the last to leave your system and can take a week to 60 days.
About a month
Not using any for a long time will do it.

I do believe after one month of smoking marijuana it will clear out of your system but I also believe it depends on how long you were smoking tge marijuana for.
I,ve learned over my years that there is no way to flush marijuana out of your system but it does not stay in your system as long if your skinny and dont smoke alot of it
Water will NOT help clean your system of marijuana. See the Related Question below.
How long does marijuana stay in the body system after taking say 1 joint.
