Health Alert: E-Cigarette Vapor Potentially Harmful

A new report suggests that e-cigarette vapor produces tiny particles that can be inhaled deep into the lungs, potentially causing or accelerating respiratory diseases. Investigators are unsure whether these chemicals are harmful if you inhale them, as safety research is only known regarding ingestion of these chemicals. The authors believe researchers need to come together and set standards for researching e-cigarettes, given that there are so many different liquids and devices available to the public.
