I have had to take hair follicle test before and it doesnt matter when the last time was you done any kind of drug, pain pill, xanex or anything like that. They can tell by your hair the very last time you done anything and it doesnt matter if it was 5 years ago. Some places cut your hair for the test & some places pull it from the root. If they cut it then you can go to a place that sells things to wash your hair to get it out & trust me it works because I past mine that way. Make sure you get the best hair stuff they have and follow the directions on the box. I had to wash my hair an hour before the test and it only keeps your hair clean for a hour or so. If you go to a place where they pull your hair from the root the hair stuff will not work because you can't wash your roots. Good luck!
