I was in a similar situation back when I was in Catholic high school. After the friends I had initailly met learned that I smoked most avoided me like the plague. There were other tokers at the school, however, and gradually I ended up hanging out with them: the "wrong crowd". LOL. I eventually got kicked out of the school after two years, actually they asked me not to return after the end of the year, but I didn't care because we were moving anyway.

I ended up going to 3 different high schools(parents moved a lot) and each time pretty much the same thing happened. In my experience the stoners hung out with the stoners, jocks hung out with jocks, etc etc. That was nearly 20 years ago so things may be different now but I expect they aren't.

I hate to say this but my guess is that you'll need to make new friends. Now that you're smoking you'll want to hang out with others that smoke too. In the meantime, don't go advertising the fact that you smoke to those that don't. As your friends start to change the old friends that might have such a problem with it just won't pay attention anymore and there will be less chance that they'll call your parents.

If your folks do find out ezjim's "just curious" and Ousted's "religious nut" excuses are pretty good. I really don't have any other advice since I didnd't too very good in the area of handling the parents. I was always getting busted by my parents and even the police once. My smoking pot was a huge strain on my realtionship with my parents and we fought about it continuosly until I moved out. Now, however, I have a great relationship with them and its like all those bad times never happened. So just remember, even if they do find out and freak, they'll get over it eventually.
