People have been stealing and killing other people as many years if not longer. That doesn't mean you cannot do a bit of legislation and obtain some positive results against that.

I think not banning the cigarette and non reusable vape is the wrong solution but banning smoking in lots of public spaces has improved the situation, maybe not to curb consumption but at least non smokers can breath a little. I wish it would also applies to outdoors cafe/restaurant terraces too as smokers effectively ban to non smokers by spreading their poison around them. They could walk away for a couple of minutes to get their hit but they don't on purpose. There should be a radius around an outdoor terrace where smoking is effectively prohibited.

Outdoor cafes/restaurant terraces that allow smoking effectively are marketing to smokers. Smokers generally stay longer (therefore may order more), and basically are giving themselves dopamine at this venue, therefore creating associations to possibly draw them back in the future. These places could just not provide ashtrays and could just not allow smoking, but they do allow it, because it's good for business.

If you really don't like it, you could just not visit these establishments. To these businesses, the benefit of allowing smoking doesn't outweigh the negatives (some people not liking it). Obviously you don't not like it enough to just not go there. Not a smoker, but i've never understood this puritanical attitude towards smoking and only smoking. Yeah, it's not great to breathe in an enclosed space, but in an outdoor space, I don't see how much worse it is than car exhaust, air quality, etc.
