Separate research has raised concerns about mental health risks. Dr. Daniel Myran warned of links between cannabis use and psychosis, particularly in young men. He noted sharp increases in emergency room visits tied to cannabis-induced psychosis and higher risks of later anxiety or psychotic disorders.
