I'll +1 to the other comments here of people who stopped smoking cigarettes and took up vaping. I didn't even intend to quit, and I know a lot of other people in the same situation.

For some people, vaping is just far more pleasant than smoking cigarettes and they don't look back.

The couple of times I started back up again with cigarettes early on was when I ran out of e-liquid, since it is heavily regulated (or illegal, as in AU) and can be difficult to obtain.

I really find this result difficult to believe.
