Author Quotes:  

Even in human beings [compared with the lab tests on cells], they [e-cigs] are far safer than smoking, and what we are talking about is using these products for people who would be smoking anyway.

If you stop smoking and change to vaping, the evidence so far suggests you greatly reduce your weight gain.

If you go to the website [ATHRA] there is a whole section on vaping and other strategies on how to quit smoking.
