Medical Xpress - E-cigarette vapors, flavorings, trigger lung cell stress


Do electronic cigarettes help people quit smoking? As the debate continues on that point, a new University of Rochester study suggests that e-cigarettes are likely a toxic replacement for tobacco products.

Emissions from e-cigarette aerosols and flavorings damage lung cells by creating harmful free radicals and inflammation in lung tissue, according to the UR study published in the journal PLOS ONE. Irfan Rahman, Ph.D., professor of Environmental Medicine at the UR School of Medicine and Dentistry, led the research, which adds to a growing body of scientific data that points to dangers of e-cigarettes and vaping.

The investigation suggests the harm begins when the e-cigarette’s heating element is activated. The heating element is designed to turn a liquid solution (known as an e-liquid or “juice”) into an aerosol that mimics cigarette smoke. The inhaled vapors contain heavy metals and other possible carcinogens in the form of nanoparticles - tiny particulate matter that can reach farther into lung tissue, cell systems, and blood stream.


Unfortunately i see quite a lot of people smoking e-cigarettes unaware of the harm it can cause. I’m giving up smoking but obviously don’t want to go down that route. Someone even recommended i should take e-cigarettes.


The e cig is helping me give up nicotine. I used to be a 2 pack a day smoker. With the e cig, I only take a few hits in the morning and night. I feel I will fully give up nicotine soon, and it is much cheaper than tobacco.


I was curios as smoking one of these even without nicotine seems to be a bit triggering for my son. The main ingredient 70% in one of my sons E-liquids propylene glycol with is on this page is “generally recognized as safe” for use in food however it is listed on a toxic substance site…
