Scientists and medical professionals have long debated whether pod e-cigarettes are a safer alternative to traditional cigarettes. A new study provides some insight.

In a collaboration between The University of Kansas Cancer Center, California State University San Marcos and Brown University, scientists conducted a six-week-long randomized trial comparing e-cigarette use to traditional cigarette use in African American and Latinx smokers. E-cigarettes simulate tobacco smoke via battery-powered devices that work by heating a liquid into a vapor that the user inhales.
