I don't get vaping at all. I struggle with the concept of inhaling anything to be honest, but vaping is newer so I know less about it and don't understand how it could become popular.
I didn't get it at all before I moved to Japan since it isn't really a thing in Australia (they aren't sold in shops here so not many people have them). Once I was living there I actually saw them being used in person for the first time and I guess I kinda came to "get" it more. Some friends told me they were using it to get off of smoking which I guess is fair enough, they certainly smell a hell of a lot nicer to those around the smoker and the smoker themselves. Plus they seem to come in flavours which is another advantage over cigarettes I guess.
I'd never try it since it isn't for me. I don't see it becoming much more of a thing here though anyways since they're apparently about to slap a fine of up to $220,000 for importing or bringing vape products into Australia without a prescription.
