Bloom has not verified which seed-to-sale system the state requires for Michigan yet. Nothing is asserted here in its place.
Check the regulator directly: Cannabis Regulatory Agency (Department of Licensing and Regulatory Affairs) rules, Cannabis Regulatory Agency, Michigan Medical Marijuana Program rules, Michigan Legislature site.
An adult-use licensee may sell or transfer marihuana only to an individual 21 years of age or older, and must verify that the individual appears to be 21 or older by government-issued photographic identification containing a date of birth before the sale.
Block any single adult-use transaction that exceeds 2.5 ounces of marihuana, of which not more than 15 grams may be in the form of marihuana concentrate.
Verify in the statewide monitoring system before every medical sale that the transfer will not exceed 2.5 ounces of marihuana or marihuana equivalent per day per patient (per connected patient for a caregiver) nor 10 ounces of marihuana product per month to that patient directly or through the caregiver.
An adult-use retail sale carries the 10 percent MRTMA excise plus the 6 percent Michigan sales tax, and a product subject to the 10 percent excise may not be bundled in a single transaction with a product or service that is not subject to it unless a Treasury rule allows it.
A 24 percent excise on the wholesale price applies from January 1 2026 to the first sale or transfer of adult-use marihuana from a marihuana establishment to a retail licensee, to provisioning center transfers to a retail licensee, and to marihuana a retail licensee cultivates or processes for its own retail sale; the wholesaler owes and remits it quarterly and may pass it through on the invoice.
A marihuana business may not hold or sell product that is not identified and recorded in the statewide monitoring system or that lacks a batch number, identification tag or label, and every transaction, current inventory and other required information must be entered accurately into that system.
A sales location may not sell or transfer marihuana until it has been tested in accordance with the sampling and testing rules and bears the label required for retail sale.
Before selling or transferring, the licensee must verify in the statewide monitoring system that the product is not on administrative hold, recalled or ordered destroyed, and is not past the printed expiration date; expired product must be destroyed except that a retailer may return it to the processor that produced it.
Product sold or transferred must be sealed and labeled with the cultivator or producer name and license number, package tag, harvest date, strain, net weight, THC and CBD concentration with the 10 percent variance statement, activation time, testing laboratory and analysis date, the universal symbol, the impaired driving warning, the poison control number, the age or patient use statement and the boxed pregnancy warning, and the customer must be offered the required 3.5 by 5 inch safety pamphlet at the time of sale.
No marihuana retailer may sell or transfer marihuana that is not in an opaque, resealable, child-resistant package meeting 16 CFR 1700.20 (1995), and no processor may make and no retailer may sell edible marihuana-infused candy in shapes or packages attractive to children or easily confused with ordinary candy.
A route plan and manifest must be entered into the statewide monitoring system and carried in the transporting vehicle, the transporter may not possess product that is not on the manifest and must follow it, product rides in locked, secured and sealed containers that are not accessible in transit with money locked separately, and the receiving business must begin acceptance within 30 minutes of arrival.
Every inventory change must be entered accurately into the statewide monitoring system and supported by comprehensive financial and source records, so the POS must capture a reason and a source document on each adjustment.
Product to be destroyed must be ground or otherwise rendered unusable and unrecognizable and mixed with non-consumable solid waste so the mixture is at least 50 percent non-marihuana, recorded in the statewide monitoring system, disposed of in a secured receptacle through an approved landfill, composting facility, anaerobic digester or permitted incinerator, and destroyed within 90 calendar days of the licensee becoming aware it must be destroyed.
A sales location may accept a return only of product reported to have caused an adverse reaction or determined to be defective; returned product must be tracked in the statewide monitoring system as waste, destroyed within 90 calendar days, may never be re-sold, re-packaged or transferred to another customer or business, and may not be brought back by way of a delivery driver.
Trade samples and internal product samples may never be sold or transferred to a consumer or to another licensee; a sales location may only pass them to its own employees, capped at 1 ounce of marihuana, 6 grams of concentrate and 2000 mg total THC of infused product per employee in any 30 day period, and every trade sample must be recorded in the statewide monitoring system and labeled TRADE SAMPLE NOT FOR RESALE.
No MRTMA provision or R 420 rule was found restricting retail discounting, coupons, loyalty pricing or nominal-price promotions to consumers; the only price-adjacent constraints are the ban on bundling a taxed marihuana product with an untaxed product or service in one transaction and the bar on giving away product outside the trade sample rules.
Marihuana advertising may not be deceptive, false or misleading, may not make any health or health benefit claim without an FDA Letter of Enforcement Discretion or significant scientific agreement approval, may not be directed at individuals under 21 (or under 18 for medical product) including sponsorships, and may run only where the advertiser has reliable evidence that no more than 30 percent of the audience is reasonably expected to be underage.
Michigan has no tied-house rule; nothing in the MRTMA or R 420 prohibits a grower or processor paying a retailer for shelf space or in-store advertising, and Treasury guidance openly contemplates featured shelf space in exchange for a partner discount, but Bloom requires compliance review before selling such placements because the agreement may need agency approval and the discount cannot reduce the wholesale tax base.
Licensee records, including cash logs, sales records, inventory purchases, invoices, receipts, deposit slips, cancelled checks, employee compensation records and tax records, must be kept for at least 4 years, and longer if the agency is investigating or inspecting, until the agency says they may be destroyed.
Surveillance recordings must be kept a minimum of 30 calendar days (longer during an agency investigation or inspection), at 720p or better, covering point of sale areas, destruction areas, storage, limited access areas, transfers between rooms and every building entrance and exit from indoor and outdoor vantage points, with a failure notification system and a log of who monitors, removes and destroys recordings.
A licensee must notify the agency and local law enforcement within 24 hours of becoming aware, or of when it should have been aware, of the theft or loss of any marihuana product or criminal activity at the marihuana business, and must report delivery vehicle accidents and diversion during delivery.
Everyone at the business other than the licensee's own employees must be logged in as a visitor and escorted at all times in limited access and restricted access areas, product must sit behind a counter or other barrier out of direct customer reach, and the point of sale must be a separate dedicated room.
A marihuana sales location may deliver only after the agency approves the licensee's written delivery procedures, deliveries must occur within the business hours of the sales location, and the approval may be denied, suspended or withdrawn by the agency.
Only an employee of the marihuana sales location may deliver; the delivery employee must meet the employee rules, be at least 21, have passed a criminal history background check, hold an employee identification number in the statewide monitoring system, carry that number plus the licence number, address and contact details of the sales location and the delivery log, and keep a secure means of communication with the licensee at all times.
Michigan does NOT require a second person in the vehicle for retailer home delivery; R 420.207 speaks throughout of a single marihuana delivery employee, and the 2-person crew requirement is imposed only on secure transporter vehicles by R 420.106(3)(b) and R 420.110(4)(c), which are separate licence classes that may not deliver to consumers at all.
A secure transporter vehicle must be operated with a 2-person crew, with at least one individual remaining with the vehicle at all times during the transportation of marihuana, and each driver must hold a Michigan chauffeur's licence.
Michigan caps the value of product in a delivery vehicle but places NO limit on the cash a delivery employee may carry, and expressly allows the delivery employee to take payment on delivery.
The delivery vehicle must carry an active GPS device, affixed permanently or temporarily while the vehicle is in operation and in the delivery employee's possession throughout, so the sales location can locate every delivery vehicle and employee at all times; product rides in a clearly marked, latched or locked secured compartment, and product may not be left in an unattended vehicle unless the vehicle is locked and has an active alarm.
A delivery employee may not leave the sales location with product without at least one already received and processed delivery order, must carry a delivery inventory ledger listing product type, brand, retail value, statewide monitoring system tag number and measure for every item with pre-ordered product clearly identified, must update the ledger after each delivery, and must return to the sales location and restock if no delivery request arises for 30 minutes.
Before a medical sale the provisioning center must inquire of the statewide monitoring system that the patient and, if applicable, the connected caregiver hold a valid, current, unexpired and unrevoked registry identification card, and must view photo identification matching that card.
