Does anyone know when to use Strip NC? The directions are vague and does not specify when to use it. Do you use it right before the drug test or the night before? Or does it even work? I am 6'0 140lbs, and literally have like 4% body fat. I smoked a quarter of some fifty in the last two weeks, and before that i didnt smoke for about a month. The last time i smoked was 2 days ago and i am not smoking anymore because i am job hunting. I have been pounding water and taking niacin. I bought Strip for security. I don't know if or when i will have to take a drug test, but i need a good job so i can't chance it. If anyone has any information on this, i woud greatly appreciate it.
