Introduction

Iowa’s medical cannabis program remains one of the most restrictive in the country, to the extent that some advocacy groups do not even recognize it as a legitimate cannabis market. With stringent limitations on product availability, patient access, and dispensary operations, the state’s program offers minimal relief compared to more robust medical cannabis frameworks elsewhere. However, with several reform bills in play this session, Iowa may see incremental changes in 2025.

Current Iowa Medical Cannabis Restrictions

Iowa’s medical cannabis laws are among the strictest in the nation. The program prohibits cannabis flower, only allows two licensed manufacturers, bans home cultivation, and limits patients to 4.5 grams of THC every 90 days unless they obtain a waiver from a certified provider. Additionally, access is restricted to just five authorized dispensaries, making it one of the most controlled medical programs in the U.S.

Legislative Landscape and Proposed Reforms

While Iowa House Democrats have included adult-use cannabis legalization among their top four legislative priorities for this session, expansion of the medical program appears to have a better chance in the state’s Republican-controlled General Assembly. With the GOP holding supermajorities in both chambers (67% in each), lawmakers are prioritizing incremental reforms rather than full legalization.

Several key bills are currently under consideration:

  • House File 105, sponsored by Rep. Hans Wilz, R-Ottumwa, would allow patients to access dried flower, but only for vaporization—similar to Ohio’s medical cannabis program before adult-use legalization passed in 2023. This bill advanced out of subcommittee on Jan. 27.
  • Senate File 46, sponsored by Sen. Scott Webster, R-Bettendorf, aims to double the number of dispensaries in the state from five to ten. The Senate Commerce Committee passed this legislation on Feb. 20.

These proposals reflect cautious steps toward improving patient access while avoiding a broader shift toward adult-use legalization.

Governor’s Stance and Public Opinion

Despite increasing public support for cannabis reform, Republican Gov. Kim Reynolds remains a strong opponent of legalization. In 2022, she stated, “I believe marijuana is a gateway drug that leads to other illegal drug use and has a negative effect on our society.” Her administration’s stance significantly reduces the likelihood of any adult-use cannabis legalization efforts gaining traction in the near future.

Nonetheless, public opinion is shifting. According to a 2022 University of Iowa Hawkeye Poll:

  • 71% of Iowans support medical cannabis legalization
  • 52.5% support adult-use cannabis legalization

Despite these numbers, Iowa remains one of 24 states that do not allow citizen-initiated ballot measures, making legislative approval the only pathway for reform.

Conclusion

Iowa’s cannabis reform efforts are advancing at a slow but steady pace, with incremental changes likely in 2025. While full adult-use legalization faces strong opposition, medical cannabis expansion efforts—including increased dispensary access and potential flower availability—signal a willingness to modify the state’s restrictive framework. With overwhelming public support for medical cannabis, the coming legislative sessions will determine whether Iowa finally embraces broader reform or continues its historically cautious approach.
