i think you would have to take the niacin + drink a lot of water + exercise for like 4 days to a week for it to work really good...my friend was dumb and took like 50 of them once and passed a drug test for his PO and he only had 2 hours after he took them before he had to drop...and he couldnt leave the building so we had to get get him the pills
sevkex Reviewed by sevkex on . Should I risk it? So, I am a VERY occasional smoker. The last time I smoked was february 19th. The time before that, I smoked on January 1st. I have a drug test to get my FAA certification (I am becomming a pilot) that I can take either in March 23rd, or April 23rd. If I take it March 23rd, I can smoke weed right after that for the next year. If I take it then, though, would I pass? I cant risk this at ALL. If I get tested positive, it basically ruins my life. suggestions? Rating: 5
