From what I can see that has happen in my area. No vaping doesn't help you quit.
Nicotine is the big factor and lot have overdosed on vaps. If a person really wants to stop.They will ;vap in no way or study done helped in any dramatic way.
EVALI a identified lung disease linked to vaping
So one must ask if your promoting the idea? That it must be for a reason.
It's really simple my dad smoked 3 packs a day for 25yrs and quite one day. He had no cravings or ever smoked again. No one is better then someone else. I was able to do the same. Saying vaping helps you quite.
It's like using a walking kane. Then a new almost not there walking kane comes out.
It's still a kane and want help any one walk better or even walk without one.

Why or how can wienning off ever work.
Seems lazy to me it's simple anyone can no matter who they are.Quite and go forward

It's simple one quites or doesn't.
There's no in-between. Life's a zero some game.

I think that no. Vaping is a good opportunity to quit smoking and I liked to follow https://vapingdaily.com/ which has a lot of different interesting posts, information about current vaping kits. There possible to find last sales in order to buy the best vape you want.
