Legal notice: This page is informational only and not legal advice. Laws and rules change. Always verify on official Michigan websites linked below and follow the strictest rule that applies to you. See our Legal Disclaimer & No-Warranty and Terms of Use.
Federal Context (Still Applies)
Under U.S. federal law, cannabis remains a Schedule I controlled substance. Do not take cannabis onto federal property or across state/national borders. See United States (Federal & State Overview) and the Responsible Use Guide.
Michigan Overview
Michigan operates adult-use (non-medical) and medical cannabis programs regulated by the Cannabis Regulatory Agency (CRA). Program specifics (licensing, possession, retail operations, home cultivation rules, product testing/packaging, and local ordinances) are published and updated by CRA. Always confirm current requirements on the official portal.
Medical Program
Michigan’s medical program outlines patient eligibility, physician certifications, caregiver rules, product forms, and purchase limits. Patients should follow the official CRA/DOH resources for current processes and documentation.
Adult-Use Program
Michigan’s adult-use market is mature with statewide licensing and local opt-in/opt-out authority. Local ordinances and CRA rules affect where and how businesses operate, as well as practical access for consumers. Verify retail availability and any local restrictions before purchasing.
Driving & Impairment (DUIC)
Driving under the influence of cannabis is illegal. Enforcement approaches and evidentiary standards differ from alcohol. Do not drive while impaired and consult state resources for current guidance.
Local Rules & Employers
Municipalities may limit or condition adult-use businesses; employers may maintain workplace policies regarding cannabis. Confirm local ordinances and employer rules as needed.
Travel & Borders (Important)
- Do not transport cannabis across state lines or international borders.
- Do not carry cannabis onto federal property (airports, federal buildings, national parks).
