Abstract:
To evaluate trends in use of stop‐smoking medications ( SSM s) before and after varenicline ( C hantix™) was introduced to the market‐place in the U nited S tates, and to determine whether varenicline reached segments of the population unlikely to use other SSM s. Design Cohort survey. Setting U nited S tates. Participants A nationally representative sample of adult smokers in the U nited S tates interviewed as part of the I nternational T obacco C ontrol F our C ountry S urvey between 2004 and 2011. Primary analyses used cross‐sectional data from 1737 smokers who attempted to quit (∼450 per wave). Measurements Reporting an attempt to quit smoking; use of each of the following types of SSM s for the purpose of quitting smoking: nicotine gum, nicotine patch, other nicotine replacement therapy, bupropion and varenicline. Findings There was a significant increase in the rate of use of any SSM among quit attempters across the study period [odds ratio ( OR) = 1.15, 95% confidence interval ( CI) = 1.10–1.21 per year]. This increase was largest after varenicline was introduced ( OR = 1.16, 95% CI = 1.07–1.26 per year); however, there was a decline in nicotine patch use during this time ( OR = 0.87, 95% CI = 0.76–0.99 per year). Varenicline users were generally similar to users of other SSM s but differed from those who did not use any SSM s, in that they tended to be older ( OR = 5.46, P = 0.024), to be white ( OR = 2.33, P = 0.002), to have high incomes ( OR = 1.85, P = 0.005), to have high nicotine dependence prior to quitting ( OR = 2.40, P = 0.001) and to have used medication in the past ( OR = 3.29, P 〈 0.001). Conclusions The introduction of varenicline in the U nited S tates coincided with a net increase in attempts to quit smoking and, among these, a net increase in use of stop‐smoking medications. The demographic profile of varenicline users is similar to the profile of those who use other stop‐smoking medications and different from the profile of those who attempt to quit without any medication.
