A new study published in Translational Psychiatry suggests that chronic cannabis use may not be associated with cognitive impairment in people with bipolar disorder, contrasting with its effects on healthy individuals. The findings indicate that people with bipolar disorder who use cannabis moderately may possess better decision-making skills than those with the disorder who do not use the drug. This research offers a potential explanation for why many individuals with this condition turn to cannabis for symptom management.

Bipolar disorder is a chronic mental health condition characterized by extreme shifts in mood, energy, and activity levels. These shifts typically range from periods of extremely energized behavior, known as manic episodes, to very sad or hopeless periods, known as depressive episodes. Beyond these emotional symptoms, the disorder is frequently accompanied by cognitive deficits.

Individuals with bipolar disorder often struggle with goal-directed behaviors. This includes difficulties with decision-making and inhibitory control. These cognitive impairments can lead to impulsive actions and engagement in risky behaviors. These deficits can severely impact social relationships, occupational stability, and overall quality of life.

A significant number of people with bipolar disorder report using cannabis. Statistics suggest that over 70 percent of individuals with this diagnosis have a lifetime history of regular use. Patients frequently report using the drug to self-medicate. They claim it helps alleviate specific symptoms such as racing thoughts or hyperactivity.

Medical professionals have historically viewed this high rate of use with concern. In the general population, chronic cannabis use is typically linked to cognitive decline. Regular use is often associated with worse memory, reduced attention, and poorer decision-making. The researchers wanted to investigate whether these negative effects hold true for the unique neurobiology of bipolar disorder.
