Chicago passes its first clean air ordinance, requiring separate smoking and non-smoking sections in restaurants, airports, train stations, and bus depots. While a small handful of Illinois municipalities had established non-smoking restaurant sections over the previous decade, Chicago’s ordinance would set off a chain reaction of municipalities following suit. During this time public health organizations like RHA would advocate for stronger health protections, while tobacco industry lobbyists worked to preempt more ordinances from being passed.
