As Director of the at Mayo Clinic, has voiced similar concerns with vaping. "The key thing for people to know is vaping is not water vapor. It is a complex solution of chemicals that have been changed from their original state because they’ve been heated to high temperatures. And although these components are considered safe for ingestion, the flavorings like cinnamon, the vehicles like vegetable glycerin, they are not safe for heating and inhaling because the chemical constituents have changed."

Dr. Hays is available to speak with media about concerns associated with vaping. Please contact Emily Blahnik, Mayo Clinic Public Affairs, 507-284-5005, [email protected] to arrange an interview.

Vaping devices, also referred to as e-cigarettes, work by heating a liquid that usually contains nicotine, glycerin and other chemicals that users inhale. "Many of the chemicals now that can be inhaled are different aldehydes and other chemicals that are derivative from these original ones, and we think those are likely harmful. We know some of them are potentially cancer-causing,” says Dr. Hays.

Although it is not known what is causing the increase in lung diseases, vaping cannot be ruled out.  As Dr. Hays notes, “never inhale anything in your lungs except air."
