(Los Angeles Times) - Now the evidence is indisputable: Secondhand smoke is a major health threat that kills an estimated 50,000 people each year, according to a new federal study announced Tuesday by Surgeon General Richard Carmona. Among the report's major conclusions:

Exposure of nonsmokers to tobacco smoke increases their risk of heart disease and cancer by as much as 30 percent, reports Trend.

Even a brief exposure to tobacco smoke can increase risk, especially for people with heart and respiratory diseases.

Segregating smokers is not effective for preventing exposure of nonsmokers, and even the best available technology does not clean the air adequately.

There is no evidence that smoke-free laws have significantly reduced business at bars and restaurants in cities where they are enforced.
