Marihuana: licenses; number of marihuana retailer licenses; place limit on. Amends secs. 7, 8, 9 & 9a of 2018 IL 1 (MCL 333.27957 et seq.) & adds sec. 9b.

Michigan Senate Bill 597 (SB0597) proposes to amend the Michigan Regulation and Taxation of Marihuana Act by introducing a cap on the number of marihuana retailer licenses that can be issued. Specifically, the bill seeks to limit the total number of these licenses statewide, aiming to control the proliferation of marihuana retail establishments. The bill was introduced on October 2, 2025, by Senators Samir Singh and Jeremy Moss and has been referred to the Senate Committee on Regulatory Affairs for further consideration.

Supporters of SB0597 argue that implementing a cap on marihuana retailer licenses will help prevent market oversaturation, ensuring a balanced and sustainable industry. They believe that such regulation can protect small businesses from being overshadowed by larger corporations and maintain the integrity of local communities. Additionally, proponents suggest that limiting the number of licenses could enhance regulatory oversight and public safety by making it easier to monitor and enforce compliance among a manageable number of retailers.

Opponents of SB0597 contend that imposing a cap on marihuana retailer licenses could stifle competition and limit consumer access to legal cannabis products. They argue that such restrictions may inadvertently encourage the persistence of the black market, as consumers seek alternatives due to limited availability. Critics also express concern that the cap could hinder economic growth and job creation in the burgeoning cannabis industry, potentially depriving the state of additional tax revenue generated by a more expansive market.
