Do you have a better way to convince people not to smoke?
I'm one of these people. I enjoy smoking cigars every once and awhile, and will enjoy a cigarette or two with no danger of addiction if I happen to be drunk and at a party with smokers. With that being said, I could easily see how an occasional smoker could turn into a regular smoker over time if tobacco was readily available and they were hanging around with other smokers regularly.
You can call this lying. However, it is what advertisers have been doing for ages.
