A significant amount of data has been generated in recent years showingthat cannabis access is associated with reduced levels of opioid use and abuse. But emerging data also indicates that many patients similarly substitute marijuana for a variety of other substances, including alcohol, tobacco and benzodiazepines.
Last month, a team of researchers from Canada and the United States surveyed over 2,000 federally registered medical cannabis patients with regard to their use of cannabis and other substances. (Medical cannabis access has been legal across Canada for nearly two decades).
