Oh yes, truly a breeding ground.
Thinking back when I worked in downtown DC, a woman who sat behind me was a chainsmoker (yes when smoking was allowed in the office) and I'd be literally dying from her smoke. She was coughing up a storm and I had to breathe in her secondhand smoke. My complaints fell on deaf ears. That was a sick building - when smoking was allowed indoors. And it really wasn't that long ago or so it seems to me (1970s).
