Konstantinos Farsalinos:
"The author of the AHA abstract admits in Newsweek that his study does not prove an increased risk for cardiovascular disease from using e-cigarettes. "However, he acknowledged his study was limited in several ways. It was cross-sectional, meaning it does not prove causation but only association between disease and vaping. And e-cigarette and smoking were not quantified in the data, only if the participants were smokers or non-smokers."
That raises questions about the purpose and intentions of those in AHA who released the press statement...."
