Public health graduate students at Brigham Young University conducted an HIA to analyze potential health effects of the Utah Medical Cannabis Act (UMCA), a ballot initiative to legalize the use and production of medical marijuana in the state. The authors investigated how the UMCA might affect potential medical marijuana users, adolescents, economically disadvantaged individuals, and recreational drug users.

The researchers collected information from stakeholders, quantitative data sources, and literature reviews, and used it to divide the impacts of the initiative into six categories of effects: chronic disease and pain management, recreational marijuana use and abuse, the opioid crisis, economic stability, road safety, and use of other substances.

To mitigate adverse effects and maximize benefits, the HIA made recommendations in the following areas:

  • Qualifying conditions for medical marijuana use.
  • Regulations affecting state-level research.
  • Education of patients and physicians.


Utah voters approved the ballot initiative in November 2018, and state lawmakers then passed H.B. 3001, the Utah Medical Cannabis Act, on Dec. 3, effectively replacing the ballot proposition. The HIA’s impact is unknown.
