E-liquids often contain alcohol as an unlisted ingredient. What are the health and safety implications?

December 3, 2019

Michelle Peace, Ph.D., associate professor in the Department of Forensic Science, is studying the implications of vaping ethanol, exploring such questions as: could vaping result in false positive results for police sobriety tests? Out of 56 commercially available vape juice samples Peace‚Äôs lab tested, all but three contained ethanol, and 11 contained more than 10% ethanol. That study, published in 2017 in the journal Drug Testing and Analysis, warned that the implications of vaping ethanol as an e-liquid component are not known.

Now, Peace, an associate professor in the Department of Forensic Science in the College of Humanities and Sciences, is investigating those implications under two grants awarded by the National Institute of Justice in the U.S. Department of Justice totaling roughly $1.8 million.
