The last time I did any kind of drug was on Feb. 13th, I had a hair follicle test done on May 18th. The test is suppose to go back 3 months. Would that be March, April and May or do you think Feb. 13th is going to show up?

That is really a hard one. Understand also that the drugs stay in your follicles for an unknown period. It will also depend on what part of the follicle they test. If they are testing the portion of the follicle closest to your scalp you will probably be safe. But if they are testing the end of the hair strand, you may not be quite so lucky.

Hair test is usually administered to detect cocaine. This is the reason I always kept my hair short. Hair tends to grow at 1/4 of an inch each month, presuming that you have hair 1/2 inch long then you can dodge a 2 month screening.
