Last week I took niacin for a couple of days then tested about 6 times at diff time intervals to do some experiementing.
Made sure to have the tinyest amounts of water so dillution couldnt be a factor.

Niacin made absolutly no differance whats so ever....
yeeehaw Reviewed by yeeehaw on . Drug Test Situation i know theres prob. a thousand of these but I just want some opinions on wether or not you guys think i passed I'm a casual smoker, smoke every other day or so and usually just a blunt. I hadn't smoked in 5 days and in that time period I took 5,000 mg of niacin 2 of those nights. Look I know theres alot of debate on wether or not niacin works but I've seen a lot of my friends work miracles with it, I know i can't show the niacin is whats did it but i def. have some confidence in it.
