2. Metabolite that carry record of drug
Well, when any person consumes drug it gets into the blood stream and the blood processes the drug and produces metabolite. It is a kind of genetic record of the drug consumed. The hair follicle consumes the nutrients from the blood to get nourishment and the metabolites of drug gets into the hair strands. As hair grow the record of usage of drug passes into the hair strand. Hair follicle test may seem like that the roots of the hair will be tested but it is exactly the strand that gets tested.
