That is the question most widely ask, but nobody can say how long EXACTLY doesTHC stay in your system. The half life of THC concentration ranges between about 1 to 10 days.
This means that, for example, if THC half life in your body is 5 days and after you smoke you have about 100 ng/ml of THC in your urine, 5 days later you will have about 50 ng/ml or less and will be able to pass the test.
If a history of marijuana use is the major reason for screening, the urine test for
Cannabinoids should be able to detect prior use for up to 4 weeks in the casual user and
possibly months longer in the chronic user.
But there is too much human variations to even approximate how long THC will be detected in the urine of an individual. It depends on a number of factors.They are: human age, weight, metabolism, amount and potency of marijuana, etc. Occasional users with a fast metabolism will have the shortest detection time. Frequent or chronic users with a slow metabolism will have long detection times.
If you use marijuana on rare occasions, your urine may be clean of metabolites in less than a week. If you want to clean your system by natural way – our best detox solutions here!
There is a common and strange phenomena that occurs with chronic users. You would expect a chronic user to have the longest detection time and the smallest chance of passing. This is not always the case. A chronic user with a high tolerance will eliminate drugs quicker than an occasional user. Chronic users have tested negative after a week long binge.
As THC stores in fat cells, skinny users not only have a faster metabolism (usually), but also lack storage for THC metabolites, so pass test more successfully.
The best thing you can do for yourself is buy home drug test and test yourself after you've stopped smoking pot.
Test every day until your first urine of the day tests clean. That is how long it takes personally YOU to clean out after your normal smoking habits. Even that will vary depending on your level of usage prior to abstaining and level of activity while testing yourself. Do not rely on your best friend's experience! Every organism is different.
