BTW, "strong psychology background" doesn't necessarily mean you need to be a psychologist. You wouldn't need to make diagnoses, but if someone tells you their dx, you should know how it might relate and what questions to ask. For example, if a BP patient only drinks/uses while up or down (one or the other) then they are undoubtedly related and you need to know whether it is up or down that triggers it. I believe that my drinking/using is secondary; I only drink when I am down and learning better coping skills for depression has more of an impact than addressing the drinking by itself.
