I don't know how you could get busted. You've never smoked before, and only smoked once. Your chances of passing a drug test are extremely high, and you don't have to admit to anything.

I just found this thread and it's just a big headache. Wise up kid. Take a few years off, and maybe when you don't have to worry about parents, Christian school, and getting in trouble, have a smoke and enjoy yourself. I mean no disrespect, but it just doesn't seem like you're ready. Sorry bud.
