Matthew Large, MBBS Biography

Medical Superintendent of Mental Health Services at the Prince of Wales Hospital
Con to the question "Should Marijuana Be a Medical Option?"

“The results of meta-analysis provide evidence for a relationship between cannabis use and earlier onset of psychotic illness, and they support the hypothesis that cannabis use plays a causal role in the development of psychosis in some patients. The results suggest the need for renewed warnings about the potentially harmful effects of cannabis.”
