Asking for suggestions for a possible course on "alcohol & other drugs," probably for what at my university is called a senior capstone that combines fairly extensive reading with a research paper. Some years ago I did such a course with a focus on the Anglo-American experience with alcohol and temperance. I think that I erred then in encouraging narrower research topics than the undergraduates were qualified to attempt. Now I am thinking about broad topics based on secondary literature, but I am still feeling my way. By the way, a colleague has been successful for several years with a course on coffee (which also has produced a few conference papers and articles).
