The Three Legal Layers
Cannabis in Detroit lives at the intersection of three legal layers: federal prohibition (still Schedule I, despite the December 18, 2025 executive order directing the Attorney General to expedite a move to Schedule III), Michigan’s voter-passed legalization regime (MRTMA), and Detroit’s hard-fought municipal ordinance. Understanding which rules govern which conduct is the difference between a $0 ticket and a federal lifetime travel ban.
The MRTMA Floor
Under MRTMA (codified at MCL 333.27951 et seq.), an adult age 21 or older in Detroit may legally:
| Conduct | Limit | Authority |
|---|---|---|
| Public possession (cannabis) | Up to 2.5 oz | MRTMA / MCL 333.27951 |
| Concentrate within 2.5 oz | Up to 15 g | MRTMA |
| At-home storage | Up to 10 oz; anything above 2.5 oz must be in a locked container | MRTMA |
| Home cultivation | Up to 12 plants per residence (household cap, not per-person) | MRTMA |
| Sharing (no remuneration) | Up to 2.5 oz to another adult 21+ | MRTMA |
| Public consumption | Prohibited (sidewalks, parks, vehicles, sports venues, K-12, federal property) | MRTMA / Detroit ordinance |
Adults must be 21+. Cultivation must be in a secured enclosed area not visible from a public place “without the use of binoculars, aircraft, or other optical aids.”
The Cannabis Regulatory Agency (CRA)
The Michigan Cannabis Regulatory Agency, formerly the Marijuana Regulatory Agency (renamed in 2022), sits within the Department of Licensing and Regulatory Affairs and is the sole licensing authority for commercial cannabis businesses statewide. As of the CRA’s September 2025 statistical report, Michigan had 851 licensed adult-use retailers and 107 licensed medical provisioning centers, with 40,446 registered cannabis employees statewide. The state has surpassed $12.5 billion in cumulative adult-use sales since recreational sales began December 1, 2019.
A Detroit dispensary needs both a CRA state operating license and a City of Detroit local license issued by the Office of Cannabis Affairs (OCA, formerly the Office of Marijuana Ventures & Entrepreneurship).
Detroit-Specific Local Control: MCL 333.27956
MRTMA’s Section 6 — codified at MCL 333.27956 — is the single most important provision for understanding Detroit’s late, lawsuit-laden rollout. It allows a municipality to “completely prohibit or limit the number of marihuana establishments” within its boundaries, and to adopt “ordinances governing the time, place, and manner” of operation. That delegation of local-control power is what allowed Detroit to delay adult-use licensing by more than three years after Michigan voters legalized — and what created the legal vacuum the equity ordinance was designed to fill.
Where Federal Law Still Applies
Federal cannabis prohibition still applies on every parcel of federal land in Detroit:
- Theodore Levin U.S. Courthouse, Patrick V. McNamara Federal Building
- Detroit Metro Airport (Romulus, Wayne County)
- U.S. Coast Guard station on the Riverwalk
- The Detroit River channel itself (federal maritime / international border)
- The Detroit-Windsor Tunnel and Ambassador Bridge Ports of Entry (CBP)
- Selfridge Air National Guard Base (Macomb County)
- U.S. Army TACOM at the Detroit Arsenal (Warren)
- John D. Dingell VA Medical Center

Federal Schedule III — The December 2025 EO
On December 18, 2025, President Trump issued an executive order directing the Attorney General to expedite cannabis’s move from Schedule I to Schedule III. As of April 2026, cannabis remains Schedule I — the rescheduling has not been completed. Schedule III status, when it occurs, would unlock several practical changes (research access, tax treatment for cannabis businesses under IRC § 280E) but would not legalize cannabis at the federal level.
