A recent study shows that restaurant smoking bans help to persuade teenagers not to become smokers. Teens who lived in towns with strict bans were 40 percent less likely to become regular smokers than teens that lived in communities without bans or that had weak bans. Smoking bans discourage tobacco use and sends out the message that smoking is not healthy. The ban also reduces the amount of smoke that teens are exposed to in public places.
Having a parent or close friend that smokes can be an influence as to whether or not a teenager experiments with cigarettes but strong bans in public places play a bigger role in whether a not the teen will develop a smoking habit. The study also found that the bans had a greater effect on younger teens than older teens.
