When I was younger my dad smoked quite a lot, and after spending enough time smelling that there is no way I am going to start smoking.
Which is probably what a lot of people said when they were 16, but I'm serious. I choke each time I come close to cigarette smoke.
Unfortunately, some of my classmates have been smoking since about grade 8, and the number increases every year. When I come out of the school 15-20 minutes after the bell, there are usually about 15 people smoking in front of it. Even marijuana is not uncommon anymore, I know people who are invloved with even worse drug use (though obviously not in front of the school).
Luckily I chose my friends wisely, or maybe just lucked out, so the few of them who smoke (and are 18-20, not 16) don't put pressure on me.
