I have to do a hair test soon, I've been clean since May of last year?

I have to do a hair test sometime next week and I haven't had a single drug (Mary Jane) in my body since May of last year. Ive cut my hair every month and right now it's about an inch and a half long. Think I will pass this or should I not even bother

You will probably pass, however some drug use from a long time ago can still show up. It depends on what drugs you have taken. If they are testing for recent use, I wouldn't worry too much, especially if you have not taken anything.
