Drinking vinegar is an old trick.All it used to do is cloud the urine so they couldnt test it.That dont work anymore..I have smoked a ounce in a week and at the end of the week passed a drug test with niacine.It really works.I used to take one a day up until the day I had to piss.On the day I had to piss I took 2.Allways worked for me and friends.
Hey Phedros' can I ask exactly how you use the Niacin? My hubby has a test in a few days and has only been smoking bud, he's been stopped for a week now but is a heavy smoker. Did you stop before taking the niacin or did you carry on smoking? What strength niacin, I'm going to get some today. And then it's one a day until the morning of the test and then take two? Sorry for all the questions but it's really important that he passes it. He will try the subsistute path but it may not be possible, he also has to fast before the test so can't flush out. Thanks for your help.
