I believe it is 30 days. A month. It's one of the longer lasting illegal subjects you can take.
I've heard it stays in your system about 30 days. However, I think the potency and frequency you smoke may make a difference. Also, drinking lots of water usually helps cleanse your system quicker.
In a urinalysis test, marijuana is detectable from 1 to 6 weeks depending on the frequency at which it is smoked.
In a hair test, marijuana is detectable for a few months.
In a blood test, marijuana is detectable for less than 24 hours.
It depends on the amount you smoke and the frequency in which you smoke it as to whether a drug test will turn up negative or positive. Depending on how precise the test is it can also show up as a "trace".
If you've done a flush from your local vitamin store.that day or hours before the odds are more likely for it to turn up negative
Best bet is to do without for at least 30 days if your going for a screening, especially for a job (they tend to do the more accurate tests)
