I smoked twice in three months (2-3 hits max off a bong). The most recent being about a month and a half ago. I am very nervous as I never smoke and wasn't expected a hair follicle test in my foreseeable future. Psychemedics has a brutal reputation, online at least. I rinsed my hair with vinegar and salycic acid and was with tide several times before the test. Any input on this would be appreciated ?
