I took a charge(I inhaled a small amount of weed from a blunt) this was four months ago, I have to take a hair est so, I have a bald head so hair will most likely come from mt arm pit or facial hair, will I pass the hair drug test

Well I can think of another place for the hair to come from,

If it was only once months ago, yes most likely you will pass.

Thanks chuck, do u speak from personal experience, if u don't mind me asking

Wow, I've been trying to get someone to do a follicle test for a couple of decades, just to see what sorts of lipid soluble alkaloids are still floating around my system. At least you'll know.
