Long-timers around here will know this is a pet peeve of mine, so please excuse the soapbox, but...
We're supposed to be psychiatrists. You can't be board certified as a psychopharmacologist because there's no such thing. Training focused only on medication excludes 75% of what psychiatrists should know. Go get well-rounded training and if you choose to practice primarily in medication management, then fine. If you don't train in something, how can you evaluate its utility or whether you'd want to practice it? I posted a link a while ago to the article "The Problem of the Psychopharmacologist" (I think that's the title) in Academic Psychiatry by some former colleagues of mine (Querques, Kontos, Freudenreich - not sure about the order). Important reading for all considering psychiatry residency.
