Ice, before you give bad information, at least spell it right. It is N-I-A-C-I-N. It is a MYTH, it doesn't do ANYTHING to clear THC metabolites from your system.

So anyone who wants to listen to Ice remember, he couldn't even spell it right so that should be a gauge to Ice's knowledge on drug testing.

RPD, I have seen the detection window for oral fluids listed anywhere from 1-96 hours but for most tests that are out there it is closer to 48-72 hours. If you really choose to smoke on Fridays, make sure Monday morning you spend a lot of time brushing your teeth, mouth, gums, tongue, cheek, etc.
