“Vaping continues to be popular but not much is known about what happens with the aerosol when it enters the lungs,” says Dr. Ruud Veldhuizen, Lawson Scientist and Professor at Schulich Medicine & Dentistry. “We realized that the first thing the vapor aerosol comes in contact with in the lungs is pulmonary surfactant, which is an area our team specializes in.”
The research team was able to study the effects by placing a film of surfactant inside a syringe and, then using a vaping device to push aerosol into the syringe. This allowed the vapor to directly interact with the surfactant. The researchers then mimicked inhaling and exhaling vapor into the syringe 30 times to resemble a standard vaping session.

“In particular we were looking at the surface tension in the surfactant,” explains Emma Graham, Master’s student at Schulich Medicine & Dentistry. “After vaping, we saw high surface tension which suggests the surfactant would not be as effective at supporting proper lung functioning.”
The team also examined different vaping devices, flavors, additives and nicotine to see if there was any difference in effects.
Vaping Side Effects
“We would like to get this information out there so that people know vaping may be damaging to the lungs,” says Veldhuizen. “As a next step, we hope to further investigate the effects of vaping on the lungs and how we can treat resulting injury.”
The study has been published in the PLOS ONE Journal. These findings build on a body of research about the impacts of vaping through Lawson and Schulich Medicine & Dentistry. Our researchers were the first in the world to report on a potential new type of vaping-related injury in 2019.
