Adolescents want to be in control of all areas of their lives. So show them how tobacco addiction takes away free will, particularly the ability to stop smoking, despite a smoker's desire to quit. Smoking is not an adult habit or an effective act of rebellion. Tell teenagers who want to resist controls on their lives that their target shouldn't be non-smoking adults. Instead, they should rebel against anyone who wants to hook them on a habit that is very hard to break.
Smoking destroys good health.
Show them the probable physical effects of smoking in full detail. Warnings about future health consequences may not be as effective as other messages, though, because youth usually do not believe they will ever have serious physical problems. Show the dangers of second-hand smoke. This is as another way of telling smokers what health problems they are likely to face, and it encourages non-smoking teens to make smokers feel unwelcome. Most teenagers do not smoke.
