re: Anyone quit smoking cigarettes?

I know next to nothing about this, but I have a buddy who went from a daily smoker to an occasional vaper (if that’s a word). I know even less about vapes, and I don’t know if there is a difference between the ones people use recreationally and what he used to stop smoking cigarettes. Looks like a stubby kazoo that emits a little bit of odorless smoke that evaporates quickly.

Best of luck in your journey.
