Look at the impact vaping has had

There has been a long-term decline in the proportion of adults who smoke, but one can see that in the last three years it has really accelerated. There is no doubt this is due to smokers transferring to vaping.

Vaping is not harmless, but it is massively less harmful than smoking. Thank to vaping, we may achieve the goal of getting the smoking prevalence rate to under 5% by 2025.
