(Dec. 17, 2020) – A new study by researchers in the University of Kentucky College of Nursing shows correlations between use of electronic nicotine delivery systems (ENDS) and persistent cough among college students. ENDS include electronic cigarettes (e-cigs) and JUULS. Published in Addictive Behaviors, the UK-funded pilot study surveyed 61 UK students about their tobacco and e-cig use, and if they had experienced respiratory symptoms such as a persistent cough. Even when controlling for traditional cigarette and marijuana use among participants, the study found a greater likelihood of persistent cough among ENDS users. “College students are curious,” said Kristin Ashford, UK College of Nursing professor and principal investigator of the project. “When new products emerge, students often try them without having adequate data regarding product safety.”
