These findings were robust even after controlling for things like demographic variables, behavioral problems, and alcohol use. The authors studied data from 634 couples over nine years of marriage, starting in 1996. Couples were administered regular questionnaires on a variety of issues, including recent drug and alcohol use and instances of physical aggression toward their spouses.
Previous research on the relationship between marijuana use and domestic violence has largely been based on cross-sectional data (that is, data from one point in time), and those findings have been mixed: some studies found links between marijuana use and/or abuse and domestic violence, while others did not. The Buffalo study is one of the few to use data collected over the course of decades to examine the question, putting it on solid methodological ground compared to previous work.
