I have an opportunity for a life changing job. Just found out that I have to get a hair drug test. I'm a very infrequent pot smoker (a few times a year for several years). Recently I smoked about a joint and a half worth about 4 months ago (over a week span). I also took 2 hits about 2 and a half months ago. I've been clean since. Am I safe to pass the test in a few days?
