Abstract
- Objectives: Switching from combustible tobacco cigarettes to electronic cigarettes (e-cigs) may or may not help smokers to reduce cigarette consumption and toxicant exposure. This pilot study investigated the effects of asking smokers to switch to e-cigs for 6weeks on smoking, exhaled carbon monoxide (CO) concentration, dependence, and motivation to quit smoking.<br />Methods: Non-treatment seeking daily smokers (n=18) were given free e-cigs and instructed to use them instead of smoking cigarettes for 6weeks. Smokers were assessed at baseline, weekly for 6weeks, and at 8 and 10weeks for cigarettes/day, e-cig use, CO, cigarette dependence, and Contemplation Ladder.<br />Results: All participants completed 6weeks; 17 completed 10weeks. At Week 6, cigarettes/day were reduced by two-thirds and CO by 45% from baseline (p's<.001), with reductions maintained at Week 10 (p's<.005). Cigarette dependence scores were a third lower at Weeks 6 (p<.002) and 10 (p<.001) than at baseline. Contemplation Ladder scores were higher at Weeks 6 and 10 (p's<.001) than at baseline. All these statistical effect sizes were large. At Week 6, number of reasons not to use e-cigs increased (p<.011).<br />Conclusions: Results show preliminary evidence for beneficial effects of short-term switching to e-cigs by non-treatment seeking smokers in terms of reduced smoke toxicant exposure and cigarette dependence, and increased motivation to quit, all maintained at least 4weeks after free e-cigs were no longer provided.<br /> (Copyright © 2018 Elsevier Ltd.
