I was a regular user of marijuana,I haven't touched a thing in 45-50 days.will I pass a hair follicle test at a cutoff of 1 pg/mg? I have never in my life touched any other drug,my hair has always been cut every month. I keep it cut 3/4 inch long.I shave chest and privates always and my armpit hair is only around 3/4 to 1 inch long.
