Reminds me of a discussion at a students' senate meeting on campus a few years back, when they were discussing banning tobacco smoke everywhere including in the parks away from buildings. People who noted that PM2.5/PM10 emissions from construction sites (ubiquitous at the time), or even BBQs, where much greater than cigarettes, even if all people on campus were chain smoking (we maybe had 5% smokers), were ostracized. The times we live in lol.
