How can I p a drug test if they use your hair follicle.?

Try your hardest to beg out. Hair follicle drug tests can detect drugs as far back as 6 months and in some cases even longer ie. alcohol. Shaving your hair off won't work either because they can use any hair, or they will just ume you are hiding something and you will automatically be labeled as suspected positive. Best way to p = Don't do drugs
