Before the smoking ban was set in place in March, researchers met each participant one month to test the volunteer's breathing, sample their blood and note their health. The researchers continued the tests one and two months after the ban was set. One month after the ban was set, only 41 had shortness of breath, eye irritation, and a running nose. This number was decreased slightly from the 61 who reported these symptoms before the ban, and continued to decrease the next month, the researchers report in the "Oct. 11 Journal of the American Medical Association."
The people who worked at pubs also took tests. One showed that the workers had less white blood cells in the bloodstreams two months after the ban was set than before. This showed reduced inflammation. The second test calculated the workers' breath for nitric oxide, a gas that is made by inflammation in the lungs. Workers who were in good health showed no change after the ban, "but bar workers with asthma showed a 20 percent drop in expelled nitric oxide by 1 month afterward."
Even though the ban makes the workers and bar-goers healthier, the bar and restaurant owners are opposed to the ban, saying it will cut into their profits. The bars owners who strongly oppose the ban can sign for a waiver to allow smoking in their bars.
Questions:
1. If the ban in Scotland worked well, why didn't the US have one set before?
2. Wouldn't the ban help the bar owners increase profit because more people are against smoking?
3. Why would the ban affect the bar owners that much when they can get a waiver?
