I've had 2 hair follicle tests, and a fingerprint test in the last 6 months. I've also had numerous urine tests. I pass all urine tests, but fail hair follicle and fingerprint tests. I never have used meth. but thats what i keep testing positive for on hair and fingerprint tests. I don't use any medications. I have a habit of sucking on cough drops, and I smoke menthol cigarettes. I also have 2 pilar cysts on my head. Any ideas on what can be causing false positives. I'm at a loss. And on probation, so there probably going to send me to jail for something I'm not doing.
