A recent report from The Centers for Disease Control and Prevention has revealed that 60 percent of America's biggest cities are smoke-free.
Smoke-free laws have greatly helped reduce the exposure to secondhand smoke, reduce smoking, and improve health. It has also made a difference in reducing the number of heart attacks.
Smoke-free laws have resulted in reduction in smoking among Americans. Nearly one-third of the largest US cities in America are now governed by local comprehensive smoke-free laws, according to the CDC.
