ABSTRACT
Research over the past 30 years has explored the prevalence and possible
causes of substance misuse among people with schizophrenia, as well as
highlighting some of the complications that can occur as a con-
sequence. While these studies have significantly improved the under-
standing of the complex interplay between drug misuse and
schizophrenia, only a small number of research studies have evaluated
treatment interventions aimed at improving outcomes for this group.
