Cannabis linked to risk of self-harm, death in youth with mood disorders

Adolescents and young adults with mood disorders are at increased risk for self-harm and all-cause mortality when they also have cannabis-use disorder, a study shows.
US researchers examined Ohio Medicaid claims data on 204,780 youth aged 10-24 years who had been diagnosed with mood disorders between 2010 and 2017 to see whether risk of self-harm or death from any cause within one year of cannabis-use disorder diagnosis was increased.
