Cannabis use (aka “weed”) exacerbates mania and depression in bipolar disorder
Weed is linked to an increase in both manic and depressive symptoms and poor clinical outcomes in people with bipolar disorder.
Researchers found that the likelihood of using weed increased when people were in a good mood.
Cannabis use was also associated with an increase in positive mood, manic symptoms but, also, an increase in depressive symptoms.
