Minnesota cannabis events, conventions & dates
Conferences and trade shows held in Minnesota, the state’s regulatory, licensing and tax dates, and — because they apply here too — the nationwide retail sales days and federal policy dates. Subscribe to the Minnesota feed and it all lands in your own calendar.
Minnesota is one of the newest adult-use states — legalized in 2023, regulated by the Office of Cannabis Management (OCM), with the market's rules still being written: the 2026 cannabis omnibus bill took effect August 1, 2026, and a medical-combination-to-microbusiness conversion option opens January 1, 2027. That makes Minnesota's calendar unusually regulatory for its size, and it is why applicants and license holders watch it.
On the convention side there are three dated shows for 2027: Lucky Leaf Expo Minneapolis, February 26–27, 2027, with its pre-show crash course on February 25; the NECANN Minnesota Cannabis Convention at the Minneapolis Convention Center on May 14–15, 2027; and CannaCon Midwest in St. Paul on July 15–17, 2027 — all confirmed on the organizers' sites. Anyone searching for a cannabis convention in MN in 2027 has those three dates; the Minnesota feed below adds the state's rule dates and the nationwide sales days.

Federal hemp status ends for non-naturally-producible cannabinoid products
First of two federal hemp dates now fixed in statute. H.R. 6500 (the Continuing Appropriations and Extensions Act, 2027, signed September 2, 2026) delayed most of the November 2025 hemp redefinition to December 11, 2026 — but products containing cannabinoids "not capable of being naturally produced by a Cannabis sativa L. plant" lose federal hemp status on the original date, November 12, 2026. Cannabinoids the plant can produce but that are converted or synthesized outside it (much of the delta-8 market) stay covered until December 11. See the December 11 entry for the main effective date.

Federal 0.4 mg total-THC cap on hemp-derived products takes effect
Statutory effective date for the federal hemp redefinition (Sec. 781 of Public Law 119-37, as delayed by Sec. 2019 of H.R. 6500, signed September 2, 2026). "Hemp" switches from a delta-9 THC test to a total-THC test that captures THCA, and finished consumer products are capped at 0.4 mg per container of total THC and similarly acting cannabinoids — expected to remove most intoxicating hemp-derived products (delta-8, THCA flower, hemp-THC beverages) from interstate commerce. Fiber, grain and compliant CBD products remain hemp. Products with cannabinoids the plant cannot naturally produce exit a month earlier (November 12). Congress could still amend the date or enact a regulatory framework before it lands; the same law funds the government only through December 11, so the next appropriations deadline falls on the same day.
