How long can they detect it? I've heard the standard is 3 months, but I've also read about people who got caught from smoking like 6 months prior to the test. I smoked way back in April (so it's about 4 months ago). I only did it once, and didn't smoke much at that. Before that I only smoked back in January and earlier. I also have fairly long hair, which I heard makes it easier to detect. So, what should I do?
Hair tests are the ultimate. Someone should correct me if I'm wrong, but I'm pretty sure they go back 7 years. That might be wrong but I know it's at least a year. Shaving your head doesn't work either. You have hair everywhere on your body. The only solution is to take sulfuric acid bath.
