Smokers have no rights. Local businesses particularly bars and taverns suffered greatly when people (who were not customers btw) passed legislation that prevented smoking in these places.

The last time I was in the hospital I had to sneak out to my car to smoke, which was technically illegal as it was a non-smoking campus, no smoking permitted on the property at all. I wasn't aware that there were still hospitals that permitted smoking anywhere. The last hospital I worked at closed down the smoking breakroom and prohibited employees to smoke on the property.
