Treatment for dual diagnosis in Denmark is divided between a medically based psychiatric treatment system and a socially oriented substance use treatment system; consequently, in order to deliver the most effective treatment to people with dual diagnosis, the two need to cooperate.

I suggest that at least part of the answer lies in the unequal power relations between psychiatry and substance use treatment.
