Adults in countries where smoking is frowned upon are familiar with the no-smoking signs, designated smoking areas and general restrictions on their ability to smoke when and where they wish. But these rules -- legal, physical and social -- can offer tempting lines to cross for young people who tend toward risk-taking behavior.
There's a thrill that comes from breaking rules. Combine that with the natural tendency of many teenagers to push the limits of rules imposed by school, parents and their communities, and it's no wonder that many young people will instinctively push against any limit.
For some young people, smoking provides fertile ground for getting that limit-pushing thrill. Since it's illegal in many countries for minors to purchase tobacco, the process of obtaining, learning to use and eventually smoking tobacco is full of broken rules from the first step. Teens get thrill after thrill from breaking so many rules, enough so that the rush can overcome the sickening effects of those first few cigarettes.
