We had quite a few people coming in to UofM with the intention of a PharmD/PhD, but there's only a few left. I assume they really want to be in academia, but I don't know how they're going to fit a residency into their plans (if at all). Most of the people who quit the program just thought the PharmD program was overwhelming, or they discovered that they only want to go through 4 years of educational rigor. I even foolishly thought about it at one point in time 🙂
Also, you have to think about what your PhD is going to be in - focus towards pharmaceutical sciences or social administrative?
