While viewing images of cigarettes, smokers reported milder cravings when they shifted their focus from the pleasures of smoking to its harmful effects. Brain imaging showed a correlation between the reductions in craving and altered activity levels in regions associated with emotional regulation and reward.

April 2012 Dr. Volkow discusses NIDA’s efforts to develop effective antismoking treatments for populations with persistently high rates of smoking, such as people with psychiatric disorders, high school dropouts, and Native Americans.

In animal studies, nicotinic acetylcholine receptors with the α5 subunit played a key role in producing aversive responses to nicotine, thereby dissuading further consumption of the drug.
