People with cannabis use disorder are at a higher risk of being diagnosed with depression, non-psychotic and psychotic bipolar disorder, according to a study of over 6.5 million people in Denmark. The researchers looked at diagnosis data for cannabis use disorder (CUD) against diagnoses for these psychiatric disorders, and say CUD was associated with a higher risk of all of them, especially psychotic bipolar disorder. The researchers say the risk of being diagnosed with depression or bipolar disorder was highest in the six months after CUD diagnosis.
