Hi Sochi - you're not being stupid... most teens are curious about the stuff that's forbidden. The problem is that it's forbidden for a reason - it's not good for people in general, and especially for young people who are still developing - but the fact that it's forbidden makes it SO tempting. So all of this is just advice from people who have some experience... you can take it or leave it.
I will let you know my experience as relates to this stuff. In my household growing up, smoking was a BIG no-no, but alcohol was no big deal (Jewish culture - fairly relaxed about alcohol, and my parents would let us have wine at religious holidays, and give us tastes from their glasses of wine). So, with that contrast - what happened to me? I was totally drawn to smoking cigarettes and couldn't care less about drinking. It just was boring, because my parents didn't disapprove. Not to say that I don't drink now - I have occasional drinks. But I never had the binge drinking that I saw in my high school friends and first year of college. I had no interest in getting drunk for its own sake.
All that is to say that the attraction to smoking for me was the fact that it was forbidden. Things that our parents are against are very appealing. Just something to think about - I know you said you don't want to smoke now. I wish I had realized this earlier because I never would have become a smoker.
