drug tests....niacin?

I just recently quit smokin pot for a drug test i have to take in about 2 weeks. i'll have about 3 weeks of not smokin under my belt. This girl tho told me she had a pill called niacin, which can help pass a drug test. any ideas for passin a test at all and information on this niacin is appreciated.
thanks

 

im feeling quite generous today so

how much weed were you smokin before you stopped?

 

a little less than a month ago i was smokin just about everyday, then cooled down to maybe every 2 days, than a week ago stopped all together

 

hmmm well how much (gram wise) were you smokin per day

 

no more than 2 grams a day....prolly an average of .5-1 gram a day

 

If your quitting for three weeks you will be perfectly fine. I used to smoke everyday, quit for 5 DAYS and passed my test. But on the niacin subject, I would get 350 mg NO FLUSH. Basically niacin breaks down fat cells which hold the thc. Definatly get the no flush though cuz regular niacin burns like shit. Also you could go running or ride a bike for a few days straight and you'll burn up the thc. You'll be fine though.

 

i heard charcoal pills can help you pass a test. is that true?
