Column in question - [Does smoking have any health benefits? 1995](http://www.straightdope.com/columns/read/1101/does-smoking-have-any-health-em-benefits-em).

In light of the most recent review of all previous papers dealing with smoking and Alzheimer’s ([Cataldo _et al_. 2010](http://iospress.metapress.com/content/6607446363270216/)), it may be wise to update the column. This study found that non-tobacco industry affiliated papers indicated that smoking was a significant risk factor (averaging 1.72 ± 0.19 (P\< 0.0005)) in developing Alzheimer’s. Mysteriously, affiliated papers (not always disclosed in the paper) yielded an odds ratio of 0.86 (95% CI, 0.75–0.98).
