Previous research as shown an increased prevalence of substance use disorders among individuals with bipolar illness with some reporting a lifetime occurrence as high as 60%. Those with excessive substance use have been found to have poorer educational attainments, reduced occupational standing, poorer medication compliance, and more suicide attempts compared to those individuals with bipolar disorder who do not have a history of a substance use disorder.

While cognitive difficulties have been reported in those with bipolar disorder with a co-morbid substance use disorder, including our group's work from 2012, the scientific literature is mixed as to the extent and impact of the clinical and cognitive difficulties and few studies have examined the specific effects of alcohol and marijuana use disorders in bipolar disorder, which is what Dr. Marshall is currently investigating and will be presenting on.
