Kids might wonder if it's possible to smoke every once in awhile without becoming addicted. Can't they just smoke when they want, like at a party or with friends, and stop later? This can be tricky. Maybe the child heard this as a rumor, or from an unreliable source. However, it's actually true that about 10 percent of people who smoke are not addicted to nicotine [source: Reinberg]. But when you talk to your kids, stress the highly addictive nature of nicotine, not this small percentage. Nicotine is extremely addictive -- more addictive than heroin, in fact [source: University of Minnesota]. Explain to kids that it's not worth taking the risk just on the chance that they are in that lucky 10 percent. Also, while non-addicted smokers won't have physical withdrawal symptoms, they will have many of the same powerful psychological urges to smoke that all ex-smokers struggled with.
