Can a hair follicle drug test detect how much hydrocodone you have taken?

Yes it does buddy, better get you some of that shampoo from your local head shop. Oh and heres a tip, they like to be sneaky and take it from places on your body. No joke, been there myself and got popped for coke. Needless to say I ended up getting my parole revoked. So either shave your body and use it on your head or get enough to do EVERYTHING. Youll be alright if it's been 90 days though. Hair follicle testing only works for the last 90 days.
