Yes, of course they do. There are laws against creating a disturbance.
Yes, personal responsibility is very important as long as detriment to others is absolutely proved and not just an allegation by one who simply doesn't care for what someone else does.
Another fairy tale believer who doesn't think it possible for smoke to pass from one apartment into another. It's all a scam made up to abuse poor smokers.

Begone, you have failed to prove your point.
These people were there for 5 years before it became an issue..............
Personally I think the HOA went after the wrong people - they should have gotten together and gone after the builders.
We lived in a townhouse for 11 years, and to say these were poorly constructed would be an understatement (the builder has a notoriously rotten reputation, and these units were more than 20 years old when we bought) and never once did we notice odors from our neighbors or vice versa. Roaches and rodents, yes, odors never.
