Vaping

I got two questions coming from a non-vaper myself.

1. Why do non-smokers who never smoked cigarettes decide to start vaping? I get that its less harmful than smoking cigarettes but I feel like saying vaping is better than cigarettes is like saying having 1 broken leg is better than having 2 broken legs (which i assume is true, idk, ive broken my leg before but not both at the same time) but what if both legs were completely fine to begin with?

2. Why do vapers say they hate vaping but then start glazing about a new vape flavour or device afterwards? I’ve only been around 2 people ever who did that so it’s probably not everyone, but it just seemed hypocritical to me. In my life i dont think i have ever disliked something and then started hyping it up later one but idk im weird.
