Accidentally Smoked Cocaine. How to get out before pre BCT drug test. HELP!?

I recently enlisted in the Army National Guard and I've never been a drug user, not even Marijuana. However, yesterday I went to a friend's house and they were smoking hookah there, which is just flavored tobacco. After I had been smoking the hookah for a few minutes, I found out that they had sprinkled cocaine on top of the shisha (flavored tobacco). I ship to bootcamp in two weeks and I need to get this out of my system as fast as possible so that I don't get kicked out for something I didn't mean to do. Any suggestions on how to cleanse my system?
