Changes in cannabis-attributable hospitalizations following nonmedical cannabis legalization in Canada

JAMA Network Open

JAMA Network

About The Study: This study of 26.9 million individuals in four Canadian provinces found that cannabis legalization with restrictions was not associated with an increase in hospitalizations due to cannabis but commercialization was. The findings suggest that commercialization of cannabis may be associated with increases in cannabis-related health harms, including cannabis-induced psychosis. 

Authors: Daniel T. Myran, M.D., M.P.H., of the Ottawa Hospital Research Institute in Ottawa, Ontario, Canada, is the corresponding author.
