What kind of Niacin do i buy to pass a urine test?

I just smoked 2 weeks ago and I want to play it on the safe side...what type of Niacin is the best to pass a urine test?

You do know smoking Marijuana 2 weeks ago is a positive Urine for Marijuana use, Nothing will change your positive laboratory test Boo! I beg you! Don't believe that these methods work really try nothing if you are speaking of marijuana and you knew the risk when smoking! hay I can tell you this not for a piss test but for a health tip alright: you should always daily drink Vinegar and water little vinegar and lots of water this is very good for many things cleaning the system to heart burn really
so just drink plenty of water alright for health benefits and this advice is only good advice!
Hay i would like to know whom or where did you hear Niacin cleans the system from Marijuana if this is the case Drug test would not be necessary really! Don't believe the Hype"!

You dont want niacin - you want riboflavin and creatine. Thats the stuff in all the expensive drug test stuff that makes them work. Those two buy themselves are cheap, and because they are not packaged for desperate fools who get themselves into sticky situations, they aren't going to charge you for desperacy.

Go ahead, check the expensive stuff, you'll see what I'm telling you is true - they will have other herbs in them, but its not what makes them work. Trust me.

Niacin will NOT help you pass a drug test. If you have any doubts, don't take the test yet (unless you have to). However do not count on Niacin to help you with that.

You may need to look at this for a different direction.

Why are you smoking when you know that something in your life means that can and will be tested? For that matter, why are you smoking, period?

It is entirely possible to be clean and still have fun.

If you are smoking in order to help to manage a legitimate medical problem, then there should be a letter on your file from your doctor(s) to that effect, and that drug test will be checking for excess levels of drugs instead of for drugs in general.

Try cleaning up your act and you won't have to worry about masking agents for a urine test.

you could always get some clean piss form a freind and hide it in a tampon in ur vagina if ur a girl or tape some **** to your stomach or *** if ur a guy and if youre really desperate dip it in some toliet water if u can
