Having been tobacco free for 4 years now, I probably could have told you this. But, it’s great to have medical evidence to back it up! In this new study, researchers got a group of former smokers to use a certain vape device exclusively for two years. The test subjects were allowed to smoke, but only if they were vaping 80% of the time. During the trial, researcher were continually examining the test subjects and zeroing in on several different key markers on their health. Results? Researchers found no negative effect on the test subjects! Well, duh. You can check out a PDF of the actual study report below. That is, if you’re into that highly proper scientific speak.
