Background: In response to the legalization of retail marijuana by the voters of Colorado, lawmakers required the Colorado Department of Public Health and Environment to empanel a Retail Marijuana Public Health Advisory Committee.  The committee was required to submit a comprehensive report on the literature review findings to the General Assembly and the Boards of Health and Revenue.  The Committee was required by statute to:
  • Review  and judge the scientific literature available on health effects of marijuana use
  • Come to consensus on population health effects of marijuana use and  translate the science into public health messages.
  • Recommend public health related policies.
  • Identify and prioritize gaps in science important to public health.
  • Recommend public health surveillance activities.

Methods: The committee established a series of topics on potential health effects of marijuana use, and public health priorities identified. Outside technical experts were recruited to search the scientific literature and summarize and present findings to the full committee.  A systematic search of peer-reviewed publications was conducted using MEDLINE.  Publications were reviewed and the strength of the evidence was graded, based on the weight of evidence. Evidence statements were agreed upon by consensus and  translated into public health statements for public health education. 

Results: The committee identified several significant public health findings, including risks to adolescents who use marijuana and increased risk of a motor vehicle crash when operators use both alcohol and marijuana.  The evidence statements provide the scientific foundation for Colorado’s continued efforts to collect data about both populations at risk, using survey data and also data on adverse health effects and to use this data to inform education and prevention strategies.

Conclusion:  Colorado’s citizens benefit from the proactive, systematic, collaborative processes in place to monitor marijuana use following legalization  and potential health effects related to use.
