Reluctance to use smoking cessation medication has been identified as most important barriers to successful smoking cessation in the general population. While pharmacologic intervention, especially prescription drug, is recommended by the guideline as most effective therapy for smoking cessation, only a few smokers who visit doctors take medication reflecting serious underutilization of the pharmacologic intervention. Although it seems to be at least equally effective in Asian population compared with the Western counterpart (Fagerstrom, 2010), data from Korean National Health and Nutrition Examination Survey shows that only 0.5% of current or formal smoker reported they had been prescribed smoking cessation medication, far less than those reported from US, UK, Australia, and Canada.
