Skin follicle. This will depend on which test they are using and how fast your hair grows. Discuss with your testers.
I had a hair follicle test that showed positive for methamphetamines. The drugs I take are Zoloft, vyvanse, trazadone, and Wellbutrin. Why??
Most likely Vyvanse. Vyvanse is a prodrug that is metabolized into amphetamine by its passage through the liver (its chemical name is lisdexamfetamine), so it is not unusual. Wellbutrin is also a very similar molecule to amphetamine, but I am not sure whether it would show up as a positive in a hair follicle test. Read more...

If the screen came back positive at 864, he has meth in system. Read more...
