Hawai‘i’s medical cannabis program is effectively serving patient needs and is a the primary source of cannabis for the registered patient population, according to a new independent report.

The economic analysis was commissioned by the Hawaiʻi Department of Health, Office of Medical Cannabis Control and Regulation, to assess the performance of Hawaiʻi’s medical cannabis program and to evaluate the potential size and impacts of a future adult-use cannabis market.

The report, prepared by Cannabis Public Policy Consulting, shows that Hawaiʻi’s regulated medical cannabis system captures approximately 86% to 87% of all cannabis spending by registered patients and that monthly medical cannabis sales total about $5.3 million.

Andrew Goff, program manager for the Office of Medical Cannabis Control Regulation, said he was pleased with the findings, highlighting the strength and performance of Hawaiʻi’s medical cannabis program.

“Any expansion beyond medical use must account for the real costs of safeguarding public health,” Goff said. “Revenue generated should be directed toward substance use treatment, mental health services and comprehensive public education, as well as investments in the emerging cannabis industry, including workforce development and social equity initiatives.”

The analysis estimates that the current total cannabis demand across all sources is approximately $17 to $32 million per month. While an adult-use market may generate new tax revenue, the medical cannabis office emphasized that those gains must be weighed against the costs of protecting public health and supporting a well-regulated industry.

Ann”Increased availability is likely to lead to higher overall use, which may increase rates of cannabis use disorder, drug-impaired driving and youth exposure,” a press release from the Department of Health stated. “Sustained investment in prevention, education, treatment and safety initiatives is necessary to reduce preventable harms and protect vulnerable populations, particularly youth.”
