THCa in Michigan: Restricted
MRTMA (MCL 333.27953) defines THC to include THCA, so THCA flower above 0.3% total THC is marijuana and sells only through CRA-licensed retailers, not hemp shops. The CRA has issued advisory guidance saying so directly.
Separately, the federal hemp definition changes on November 12, 2026, when total THC replaces delta-9 as the test and finished products are capped at 0.4 mg of total THC per container. That applies nationwide regardless of state law.
Status reviewed July 30, 2026. Hemp rules are changing quickly and several are in litigation — verify against your state's statute or agency rule before you buy or sell. This is not legal advice. See all 51 jurisdictions .
