shit happens man, sorry to hear. go to the classes and kiss their ass for 3 weeks, then go STRAIGHT back to smoking . oh and when they will test you to see if youve been smoking more... they do one test at the begining, and if during/after the 3 weeks the THC levels rise at all from what they were at before, that means youre smoking weed again lol. stay out of trouble man, best of luck, that must really suck!
