In November, 3 weeks or so before thanksgiving I tripped on two drops of LSD. I'm not sure if they test for that on a hair follicle test. I also smoked half a gram of meth for a whole night in either the very end of September or beginning of October and then various uses of xanax inbetween all that. I haven't smoked weed since right after I tripped (bad experience) I usually smoke high grade, if that even matters (potency-- how long it will stay in my hair). I'm trying to apply for a job here pretty soon and would have to take a follicle test. My hair is 3 inches past my shoulders.....would I pass? I thought about buying some hair cleansing shampoo (don't know if they can detect I used it) but I use a lot of 2% zinc shampoo and have really strong liquid steroids for bad dandruff. would this clean my hair follices? Sorry if this is in the wrong spot, thanks.
