There is another study that offers strong support for the dangers of both smoking and second-hand smoke. The study at the University of California – San Francisco found a dramatic decline in hospitalizations in areas with laws banning smoking at work and public areas.
The study found fewer hospitalizations for heart attacks, strokes, asthma and other respiratory conditions.The research covered 33 different smoke-free-laws in cities and states as well as several countries like New Zealand and Germany. The study found a 24 percent drop in hospitalizations for respiratory diseases, including asthma and chronic obstruction. There was also a 16 percent drop in stroke hospitalizations and a 15 percent drop in heart attack admissions.
This would suggest a high savings in cost and illness with these laws. There is no reason why other citizens should have to bear these externalized costs. The study could also reinforce tort claims in terms of the harm caused by second-hand smoke.
