Singapore and AFAIK Thailand banned vapes altogether. And it seems to be actually enforced.
They have completely different grounds for it but still, there's already some movement in this space.
I've even seen 15-16 year old boys in Thailand pick up their girlfriends on motorbikes, race their friends to the food court, drink a couple of beers and vape once they get there, then ride their girlfriends home again while still under the influence, all without helmets mind you.
