I’ve linked to the study but you can find the full PDF displayed below.

I’ve been vaping for the last 4 years. I quit smoking over 2 years ago, with the help of various e-cig products, and I’ve never looked back. Over the last couple of years, with the vaping industry being attacked with flavor regulations, taxes, and just plain wrong misinformation, I’ve had family and friends text me links to various “studies” they found on their Facebook feeds about the “truth” of e-cigarettes. I’ve always tried my best to reply with genuine, proven facts and by sending them studies with actual sources to look over. Undoubtedly, they never attempted to read these studies, because they don’t vape or smoke. They just “wanted to pass on the info.” Which, I appreciate fully, but I know they’ll never understand the facts.

A recent study put out on Taylor & Francis Online:

The findings of this review indicate that ECs under normal conditions of use demonstrate far fewer respiratory risks than combustible tobacco cigarettes. EC users and smokers considering ECs have the right to be informed about the relative risks of EC use, and to be made aware that findings of studies published by the media are not always reliable.

Taken from the study linked above, can be found in the Abstract under “Areas Covered”

Over the last decade, e-cig use has significantly increased. These products have been rapidly gaining ground on conventional cigarettes due to their efficiency in reducing tobacco consumption, competitive price, perception that e-cigs are less harmful alternatives, and because an e-cig provides “the smoking experience without smoking.” Early products have evolved and taken shape into multiple types and products.

On the initial glance, vaping has far fewer chemicals than a typical cigarette. Cigarettes are known to contain thousands of harmful chemicals in the smoke produced. E-cigs juice is typically composed of a handful of components: vegetable glycerine (VG), propylene glycol (PG), distilled water, flavorings, and potentially nicotine. That’s the entire ingredient list. You have to “steep” your juice for a bit before use, but that doesn’t effect the recipes whatsoever. It mostly ensures the best flavor experience is going to be coming out of whatever container you choose to use. E-cigs do not contain tobacco, do not create smoke, and do not rely on combustion to operate. The composition of the e-cig aerosol is far less complex than cigarette smoke. Main toxins identified in cigarette smoke are present in e-cig aerosols (vapor), but at much lower levels than in cigarette smoke, and often at exposure levels no greater than present in the general environment.

I highly suggest you read the study, which you can find linked above or just click here. All of the points made are fully sourced and are credited in the main body of the post.
