To the Editor: There has been much public discussion recently about comorbidity between substance misuse and psychiatric disorders.1,2 Drug and alcohol misuse can precipitate, exacerbate and prolong psychiatric disorders, and is often accompanied by a range of social problems.

The facility has five closed beds and 15 open beds.
