The authors quote a study by Boffetta et al to support the idea that second-hand smoking causes disease. The Boffetta study does not support that claim. Boffetta et al found no significant association between lung cancer and passive smoking from spouse or workplace. They did find a significant association with childhood exposure: those so exposed were less likely to develop lung cancer. The results of Boffetta et al are the reverse of what your authors claim. |
