title: Self-expansion and smoking abstinence.
abstract: Helping smokers quit is important as smoking is the number one preventable cause of death in the U.S. Smoking activates the mesolimbic dopamine reward system which is also responsible for pleasure associated with other behaviors, including engaging in novel, exciting and/or challenging (i.e., self-expanding) events. We hypothesized that the reward activation achieved by experiencing self-expanding events can supplant the reinforcement normally provided by smoking and can thus facilitate quitting. We investigated this hypothesis among 74 current and 66 former smokers who reported the self-expanding events they experienced for the 2 months prior to their most successful or final, quit attempt, respectively. Former smokers, compared to current smokers, reported significantly more self-expanding events and that the events were more helpful to their quitting. For current smokers, there was a significant moderate-to-large positive correlation between number of self-expanding events and number of days subsequently abstained from smoking. The results support the proposition that experiencing self-expanding activities or events can be beneficial for smoking abstinence.
