this is my first post on this website. I was offered my appointment back in november and have been really excited, USMA is really the only school I have been looking at. I know that when I enter the academy I will be subject to a drug test. Today my teacher mentioned that it is a hair drug test, and that all drug use within 3 years will show up. Is this true? I smoked pot a few times over the summer, but haven't since my I received my appointment and dont plan on ever again, especially during my military career.
