What year was a national public smoking ban issued based on research findings?

The correct answer, 2007, is significant because it marks the year when many countries began implementing nationwide public smoking bans in response to growing evidence about the harmful effects of secondhand smoke and the overall health risks associated with smoking. Research indicated that exposure to secondhand smoke can cause serious health issues, including lung cancer and heart disease, prompting governments to take action to protect public health.

In 2006, the U.S. Surgeon General released a comprehensive report underscoring the dangers of secondhand smoke, which likely influenced the timing of legislation in various jurisdictions. Following this report, several regions escalated their efforts to restrict smoking in public areas to reduce exposure for non-smokers, particularly children and vulnerable populations. This transition into a broader public health initiative highlights how robust research can drive significant policy changes and foster healthier environments.
