Tobacco smoke has 43 ingredients that may        cancer. If smokers had learned these
      when they were young, they probably would never have started smoking.
Most smokers try        first cigarette when they are teenagers. Often, they start smoking because they think that it makes them look more        . Sometimes they start smoking because their friends tell them that it’s cool. If teenagers are told that half of them will die before the age of 65 from smoking cigarettes, how can they still think it’s cool to smoke?
