Hello, I'm about 6'1 230 pounds. I'm not 100% sure I will actually have to take a drug test, but I'm just taking any possible precautions I can. I stopped smoking last night (Sat 12/30) at around 10PM and won't smoke at all until/if I have the test. I'm a fairly heavy smoker (3-4 blunts a day if I can). I have the interview on Wed (01/02) and I'm guessing I could have the test as early as Thurs or Fri if I do have one. Now, I've heard conflicting reports on Niacin. I've drunk about a gallon of water today and taken about 400mg of Niacin. It hasn't made me feel any different so maybe I didn't take enough. I've heard it doesn't really work, but my friend was also a heavy smoker and he took it a few days before his test and passed, but he also quit for about 2 weeks. So, what would your suggestions be? I can't really afford to buy any products like a cleaner or detox or anything. I can afford to buy a home-test; and when would be the best day to test myself? Wed? My plan is to drink about a gallon of water a day until the day before the test and continue to take 400-600mg of Niacin a day. I know THC is fat soluble, but it can't hurt to drink plenty of water up until a day before the test, right? Also, I don't have any non-smoking friends who could give me substitute urine. Any help you guys could give me will be greatly appreciated. P.S. I know you guys get 50,000 of these threads a day and I looked through the current threads, but couldn't find a thread with the specific help I need.
