It still happens. Many jobs allow smokers an hourly or more frequent break, but expect non smokers to keep at it. The result is many people starting just to get the same break they should give everyone.

Dozens of the people I've known personally and most of this was in the 90s and early 2000s. I was part of the "smoke free" class of 2000 and the anti-smoking education started in Kindergarten for us. Imagine dozens of 5 year olds crying as their teachers explained with songs and videos how the adults in our lives were all going to die horrible deaths and it was up to us kids to educate them and help them quit. In school, at least twice a year. Yet by the time we reached the workforce, smoking was still a big part of the working culture and I watched pretty much everyone I knew with a full time job take up smoking at one point or another.
