TD;DR vaping as a quit method shouldn't be banned. Non-smokers should be discouraged from taking up both vaping and smoking.

It began as a safer alternative to smoking, which was an assumption. The science isn't concrete but there is some evidence vaping is safer than smoking. Note safer and not safe.

It's also easier to quit cigarettes by switching to vaping and then gradually lowing the nicotine until you're vaping liquids with no nicotine. Then it's just the habit you have to beat the addiction to and not the nicotine.

It is a little difficult to switch from smoking to vaping as cigarettes are engineered to be as addictive as possible. There are more addictive chemicals in cigarettes than just nicotine, and some added chemicals to make the nicotine in cigarettes more addictive than plain old nicotine. Cigarettes are engineered for an instant hit that fades quickly. The hit from vaping is slow and steady. It takes time to adjust to vaping and there are cravings until you do.

I think something has to be done about non-smokers taking up vaping without stopping smokers from switching to vaping, I don't know what. There's an argument the non-smokers who take up vaping would probably take up smoking if vaping didn't exist.
