Because the recent narrowing of the sex differential in smoking (and mortality from smoking-related causes) coincides with movement toward gender equality and independence among women, it suggests that rising status among women has contributed to their adoption of male smoking behavior (and ultimately to worsening longevity). However, an alternative "cigarette diffusion" explanation suggests that convergence in male and female smoking is the byproduct of a female lag in the process of cigarette adoption, diffusion, and abatement. Using multilevel models and data for 16 European nations from 1988-1995, the analysis demonstrates consistent support for the predictions of the cigarette diffusion explanation. Smoking of men and women becomes more similar in nations that have the longest history of cigarette use rather than the greatest gender equality.
