hey guys got a question for some of you recreational drug users..... i have a 6 panel drugs test coming up amphetamines, cocaine, THC, PCP, opiates, and Extacy.... now my first question is would a benzo like xanax cause a false positive on any of the 6 panals??...... and also i am being hair tested and i know that there are shampoos that supposively remove all toxins from your hair but do they really work??....anybody with prior experience??
