Hypothesis
Does a comprehensive tobacco control program lead to a significant reduction in smoking prevalence?
Conclusion
Washington State's comprehensive tobacco control program significantly reduced smoking prevalence among both adults and youth.
Supporting Evidence
- Adult smoking prevalence in Washington declined from 22.5% to 17.6% from 2001 to 2005.
- Youth smoking prevalence among 8th graders in Washington declined from 12.5% in 2000 to 7.8% in 2004.
- The decline in smoking prevalence in Washington was significantly greater than the national decline during the same period.
Takeaway
When Washington State spent money on a program to help people stop smoking, many more people stopped smoking than before.
