@mgorny Here in Queensland, it's illegal to smoke less than 5 meters from the entrance of any non-residential building.

But yeah… smoke of all kinds is a menace. A few years ago we had a bad bushfire season, and I recall spending Christmas/New Year in bed because I was coughing my lungs up.
Masks were sold out everywhere. I now have a full-face N95 (thank-you COVID-19), but yeah, bushfires or even controlled burns, are murder.
Cigarette smoke is a completely avoidable menace, and not nearly enough consideration is given to passive smoking.
Don't get me started on vaping.
@stuartl, yeah, vaping is a menace too — and I have no clue about the effects of passive vaping. It's formally forbidden wherever smoking is forbidden and it's forbidden to kids, yet every day I see hundreds of teenagers using that crap. It's a true epidemic.
