I'm going to be taking a hair follicle test within the next 2 weeks. The last time I smoked was around the begining of febuary and it was for about a month and a couple of small hits every night, but before then I was 2 months clean. I have about 1/2in. Hair and no body hair what soever (shaved everything). And bought dr.green shampoo I'm planning on using right before the test. What do you think my odds are passing?
