Abstract

Electronic cigarettes (ECs) have emerged as a popular alternative to smoking cigarettes and have also shown to decrease levels of toxic exposure. Harmful substances such as carbon monoxide and tobacco-specific nitrosamines significantly decrease in smokers who switch from cigarettes to ECs. However, reductions in behavioral social cognitive risk factors and correlates of exclusive switching have yet to be extensively studied. Cigarette smokers were recruited from the San Diego, CA area and given electronic cigarettes to use for four weeks. Questionnaires were given at baseline and at the end of the study to determine changes in behavioral and social cognitive risk factors and correlates of exclusive switching. Significant reductions in several social cognitive risk factors were found, including a decrease in smoker identification (p <. 01) and an increase in the perceived social acceptability of ECs (p <. 05). Marijuana usage in the past month decreased (p < .05), while past month alcohol use remained stable. Ever recommending ECs to someone increased from baseline to week four (p < .05). Significant correlates of dual use included greater smoking dependence motives (p < .05), less time to first cigarette (p < .05), lower baseline self-efficacy to quit smoking (p < .01), greater risk perception of becoming addicted (p < .01), and greater past 30 day use of marijuana (p. < .05). Study findings add to the evidence base for the harm reducing potential of ECs and identify correlates of exclusive switching to ECs, which is important given the relatively greater harm reduction associated with exclusive switching compared to dual use of cigarettes and ECs.

Summary of research results to be presented

This study identified the behavioral and social cognitive risk factors that improved during a four-week electronic cigarette (ECs) switching study. Questionnaires were given during baseline and at the end of the four weeks to find smoking behavior changes. Results indicated significant reductions in several social cognitive risk factors, including a decrease in smoker identification t (38) = 2.88, p<. 01, and an increase in the perceived social acceptability of ECs, t (39) = -2.05, p<. 05. Marijuana usage in the past month t (39) = -4.19, p< .05 also decreased. Ever recommending ECs to someone increased from baseline to week four, t (39) = 2.56, p < .05.

This study also revealed baseline correlates of exclusive switching, which is important given the relatively greater harm reduction associated with exclusive switching compared to dual use of cigarettes and ECs. Significant correlates of dual use included greater total smoking dependence motives, r = 0.39, p < 0.05, primary dependence motives, r = 0.39, p < 0.05, secondary dependence motives, r = 0.41, p < 0.05, less time to first cigarette, r = -0.41, p < 0.05, lower baseline self-efficacy to quit smoking, r = .43, p < 0.01, greater risk perception of becoming addicted, r = .47, p < 0.01, and greater past 30 day use of marijuana r = .35, p. < 0.05. These results can inform interventionist about addicted smokers seeking harm reduction through switching to ECs.
