Father died 3 weeks ago. I was depressed. Went home to bury him and I slipped up and snorted a few lines of cocaine. Hadnt indulged in such behavior since my late teens early 20s. Im 28 years old. My question is I snorted cocaine approximately 7 to10 days before a hair follicle and urine test. My armpit hair was taken and the hair there grows rather slowly. Will I pass my tests? Didnt know I would be required to hair test so soon either and prior to this mistake it had been well over 5 years since I did coke.
