In a recent article in Public Health Reports, Dr. Scott Weaver, Ms. Catherine Kemp, Mr. Wesley Heath, Dr. Terry Pechacek, and Dr. Michael Eriksen of the Georgia State University School of Public Health assessed the extent to which adult users of electronic nicotine and non-nicotine delivery systems (ENDS/ENNDS) use these products with nicotine. They obtained the data from the Tobacco Products and Risk Perceptions Survey, which was conducted during August and September 2015 and was administered to a cross-sectional, probability sample of 6051 U.S. adults. Participants were classified as never smokers, current smokers, and former smokers. Authors assessed nicotine content in ENDS/ENNDS by a yes or no response to the question, “Does the electronic vapor product you usually use contain nicotine?” Authors found that only 36.9 percent of ENDS/ENNDS users who were never smokers reported using ENDS/ENNDS with nicotine. These findings raise important implications for current and potential future FDA regulations of ENDS/ENNDS as well as for estimating the population health impact of ENDS/ENNDS use.
