While cigarette smoking is known to be linked to psoriasis, it was unclear whether or not e-cigarette use also carries risk. To address this research gap, a recent study analyzed data from over 28,000 United States adults, and, after adjusting for potential confounding variables, found that there is a statistically significant association between e-cigarette use and psoriasis. Hear Dr. Joe Tung, a coauthor of the study, break down its design and results, as well as potential reasons for this connection. Dr. Tung is a board-certified dermatologist who currently serves as the Medical Director of UPMC Falk Dermatology, Director of the Clinical Trials Unit, and Associate Director of the Dermatology Residency Program.
