Specializes in Addiction Medicine

Hair test: it depends on how long your hair is the average is 1/4 inch per month. so after 5 weeks the part of the follicle containing cannabis would barely be off the skin even a urine test may show for up to 6 weeks

A member asked:

How far does the testing for a hair follicle and nail drug test go back? I am getting conflicting answers on both tests. I have been told 90-120 days or longer for hair follicle depending on length of hair and up to 1 1/2-2 1/2 years for nail testing.
