Does extinction of responses to cigarette cues occur during smoking cessation?
This study showed that exposure to available cigarettes is a large risk factor for lapsing, but that this risk can also be reduced over time by repeated exposures without smoking. Smoking cessation interventions should attempt to reduce cigarette exposure (by training cigarette avoidance) but recognize the potential advantage of unreinforced exposure to available cigarettes.
