The last time i smoked marijuana was august 4, 2013. I recently smoked marijuana on march 29, 2014. How long will it take to get out of my hair?

So you need to wait a few months and then cut your hair really short to have no marijuana in your hair. One time marijuana use might not be detected but more will. ...Read more
