Some types of e-cigarettes contain enough alcohol to affect motor skills, a new study concludes. E-cigarettes deliver nicotine by vaporizing liquids, which may contain alcohol and other chemicals.
Yale University researchers tested people who used two commercially available e-cigarettes with either high or low amounts of alcohol. Neither group said they felt differently after they inhaled the vapor. But those who used e-cigarettes with high alcohol levels performed more poorly on psychomotor tests. In some cases, they had detectable levels of alcohol in their urine.
About three-quarters of the commercial e-cigarette liquids tested contained less than 1 percent alcohol. Some e-cigarette users create their own liquids with high alcohol content, the researchers note in the journal Drug and Alcohol Dependence. Almost nothing is known about the prevalence of using e-liquids that contain alcohol, they said.
Lead researcher Dr. Mehmet Sofuoglu said the findings are worrisome, especially in light of a recent government report that found e-cigarette use among teens tripled from 2013 to 2014. An estimated 13 percent of high school students used e-cigarettes in 2014—compared with 9 percent who smoked traditional cigarettes.
