Successful policies must target a difficult problem: The reward of smoking is immediate but the harm is delayed. Reminding people of disease or even death in the future aren’t always strong enough to overcome the instant gratification of satisfying a nicotine craving. Imposing taxes on cigarettes (an immediate punishment) or printing graphic images of disease on the boxes (an immediate unpleasant feeling when looking at the box) may have a better chance of helping people quit smoking. On an individual level, people can put this principle into practice by devising consequences that their loved ones can help enforce. For example, if the person trying to quit smokes a cigarette, he or she must do the dishes that night.
