A member asked:
I used to smoke marijuana regularly. no other drugs. i am 90 days since i last used. when the test comes around ill be 99 days clean. im a male and my hair is 1 inch in length. is this a sufficient amount of time to pass a hair drug test?
A doctor has provided 1 answer
Maybe. Since the average hair growth rate is cited as 1/2 in/month you & you list your hair length as 1 inch, 3 months clean should leave with a negative test. That is if they use the hair from the crown of your head and not another body part where it may not grow much.
