Probably: A standard hair follicle screen covers a a period of approximately 90 days. Metabolites from drugs Cocaine, Marijuana, Opiates Codeine, Morphine, Methamphetamine, Ectasy, PCP etc can be tested from the hair follicle.. A lock of hair 1.5 inches or 3.9 cm is snipped from the head. Note substances can be detected from body hair(grows slower) for up to a year. Good luck.
