Electronic cigarettes (e-cigarettes) may appeal to some smokers wishing to quit cigarettes who may not be attracted to other cessation aids. Similar to combustible cigarettes and dissimilar to most Food and Drug Administration (FDA)-approved nicotine replacement therapies, e-cigarettes can rapidly deliver nicotine boluses to the bloodstream and offer a user experience of inhaling aerosols with pleasant tastes and other sensory effects. Little is known about whether e-cigarette use in former smokers prevents, precipitates, or has no effect on risk of relapse back to combustible cigarette smoking. This question was addressed by Dr. Dai and colleagues from University of Nebraska Medical Center College of Public Health, in an article titled “Association of electronic cigarette vaping and subsequent smoking relapse among former smokers” in the current issue of Drug and Alcohol Dependence.
Dr. Dai and colleagues used national-representative data and provide new evidence that e-cigarette vaping more than a year after stopping smoking is associated with increased risk of future smoking relapse. They conclude “e-cigarette vaping more than one year after having quit smoking was associated with increased odds of smoking relapse at 12-month follow-up in U.S. adults. Further research determining the causality of this association is warranted to inform whether extended post-quit vaping in long-term former smokers should be encouraged or potentially discouraged due to smoking relapse concerns.”Friday Letter Submission, Publish on May 24
