I switched to vaping, IDK, 10 or so years ago from an off and (mostly) on cigarette habit and haven't looked back. There was a point where I was spending more on 'cheap' Chinese vape gear than I was on cigarettes but, other than that, no regrets.

And, yes, I'm a middle-aged adult who likes to vape flavors a well.

Perhaps the only downside, if you can even call it that, is I never tried to quit vaping as I enjoy it and it (probably) won't kill me before the lingering effects of a couple decades of smoking, environmental hazards of invading Iraq twice, the skin cancer and whatever else comes up due to my general lack of concern over living a healthy lifestyle.
