I have to take a hair follicle tomorrow that goes back 6 months. Now my concern is this, about 5 to 6 months ago I probably took within a week 7 to 10 TOTAL puffs of weed and nothing else since then. Am I in danger of failing a hair follicle that goes back 6 months even with the given information of the amount of weed I smoked.? PLEASE HELP!!
