...hair drug tests? I'm a junior in college now and I am studying to become a teacher. I smoked pot up until last summer but now I have been drug-free for about six months. I will not go back to pot by any means because I am taking my calling to be a teacher seriously, but I am worried that when it comes to getting a job in two years I might get hair tested. I have heard that these tests can reach back years. Am I worrying too much or is this a valid point?
