i had been a stoner for a long time, smoked 4-5 times a day. Then I had a test that was 30 days away. I bought a strip 7 day detox and worked out alot. In 30 days clean i passed my piss test. I know people say detox shit never works, but I would rather use it because it might help, even if just a bit, rather than not use it and fail. The more you can do to help yourself the better.
