None that I know of, but I am not as updated on research of alcohol use disorders as I am with cannabis. One interesting frontier is using machine learning methods for causal inference (the reason I have some vague knowledge of this is that my brother is working on this...). These may hopefully allow for some interesting analyses of existing data. Here is a link for his seminar on causal inference for observational studies: http://www.cs.nyu.edu/~shalit/slides.pdf
