In its report, the panel concluded that evidence suggests that while e-cigarettes are not without health risks, they are likely less harmful than combustible cigarettes.

Does Vaping Help People Quit Smoking? 

UW-CTRI Research on Vaping

UW-CTRI is analyzing its second study on smoking and vaping. The first UW-CTRI study on smoking and vaping found no clear evidence that vaping e-cigs reduced smoking or lowered carbon monoxide levels in participants. The second study did find that dual users of e-cigs and regular cigarettes smoked fewer cigarettes per day, but were taking in the same amount of nicotine. UW is also conducting a study on the acute and long-term effects of vaping.

There is still much about vaping we don’t know, including the interaction between smoking and COVID-19. UW-CTRI has called for more research.
