Hypothesis

Did the tobacco industry influence the findings of the 16 Cities Study on secondhand smoke?

Conclusion

The study concludes that smoke-free policies would significantly reduce secondhand smoke exposure.

Supporting Evidence

  • Proper analysis shows that smoke-free policies would halve SHS exposure for those living with smokers.
  • Jenkins' original article did not fully disclose the tobacco industry's role in the study.

Takeaway

The tobacco industry tried to make it seem like secondhand smoke wasn't a big deal, but this study shows that smoke-free workplaces can really help people breathe better.

Methodology

The study used standard snowball methodology to gather over 500 relevant industry documents and analyzed the full public 16 Cities data set.

Potential Biases

The study highlights potential bias in how the 16 Cities Study was conducted and reported by Jenkins and his colleagues.
