Bill Summary · HB 6163

Overview

  • Bill: HB 6163 (Michigan, 2025-2026)
  • Purpose: Amend the Medical Marihuana Facilities Licensing Act (2016 PA 281) to address marihuana plant waste, transportation, and disposal, including transportation and disposal of marihuana plant waste. Tie-in with HB 6162 (as noted in title).
  • Introduction: July 3, 2026. Referred to Committee on Regulatory Reform.
  • principal focus: specify roles, responsibilities, and allowed/regulated activities for licensees (growers, processors, provisioning centers,安全 compliance facilities, secure transporters, and marihuana disposers) in relation to plant waste and waste handling, plus related regulatory framework.

Main purpose and intent

  • Modernize and clarify the handling of marihuana plant waste and waste disposal within the licensed system.
  • Establish and codify rules around the transport of marihuana plant waste between facilities.
  • Ensure safety, security, and traceability of waste-related activities through the statewide tracking system.
  • Align disposal and waste management practices with environmental protections and environmental regulation when applicable.

Key provisions and changes

  • Definitions (Sec. 102):

    • Clarifies terms used across the act, including “marihuana plant waste,” “marihuana disposer,” “secure transporter,” and “statewide monitoring system.”
    • Establishes roles for different license types (grower, processor, provisioning center, safety compliance facility, secure transporter) and related activities.
    • Introduces “marihuana plant waste” handling concepts and related regulatory expectations.

  • Protections and exemptions (Sec. 201):

    • Licensees and their agents are shielded from certain penalties and prosecutions for activities within the scope of a state operating license, subject to act compliance.
    • Activities protected include growing, transferring, transporting, processing, testing, and other licensed operations.

  • Plant waste disposal rights (Sec. 202):

    • A marihuana disposer and its agents are protected when disposing of marihuana plant waste and transporting plant waste, provided activities comply with the act and rules (and, where applicable, environmental protections).

  • Regulatory authority and rulemaking (Sec. 206):

    • The Cannabis Regulatory Agency (CRA) must promulgate rules and emergency rules necessary to implement, administer, and enforce the act.
    • Rules must cover:
    • Facility standards, insurance requirements (subject to 408), operating regulations, and qualifications/restrictions for participants.
    • Testing standards and procedures for products sold at provisioning centers.
    • Fees, statewide monitoring system usage, and funding for the system.
    • Quality control, chain of custody, and waste disposal/storage standards for facilities.
    • Labeling/packaging, safety and health standards, and advertising restrictions.
    • Additional provisions on sale limits, information pamphlets, and appointee approvals for facility operation.
    • Note: CRA cannot require certain practices related to waste (e.g., mixing plant waste with other products or rendering waste unusable/unrecognizable).

  • Grower licenses (Sec. 501):

    • Plant counts by class: Class A (500), Class B (1,000), Class C (1,500) marihuana plants.
    • Transfers: Growers may sell/transfer seeds, seedlings, or tissue cultures to other growers outside secure transporters.
    • In-location transfers (no road access required) between grower and processor/provisioning center allowed if at the same location and entered into the statewide monitoring system.
    • Transfers of marihuana (excluding seeds, seedlings, tissue cultures, and cuttings) require secure transporter, except specified in-location exceptions.
    • Plant waste transfer: Growers may transfer marihuana plant waste to a marihuana disposer (but cannot transport plant waste themselves).

  • Processor licenses (Sec. 502):

    • Processors can purchase from growers and sell marihuana-infused products or marihuana to provisioning centers or other processors.
    • Transfers generally require secure transporters, with in-location exceptions similar to growers (same-location transfers on private property and statewide system entry).
    • Plant waste transfer to a disposer is allowed, but processors cannot transport plant waste themselves.

  • Secure transporter licenses (Sec. 503):

    • Stores and transports marihuana and money between facilities for a fee; cannot transport to registered patients/caregivers.
    • Eligibility restrictions: must not have interests in other license types and must avoid patient/caregiver status.
    • Must enter transactions into the statewide monitoring system; drivers and staff have specific conduct requirements (fitness/criminal history) and two-person crew with route plans.

  • Provisioning centers (Sec. 504):

    • May purchase/transfer marihuana only from grower or processor; transfers to provisioning centers from other facilities generally require a secure transporter unless located on the same property and transferred via private property.
    • Must have testing, labeling, and tracking for products; must verify patient/caregiver registry IDs and daily/monthly purchase limits.
    • Prohibitions: no alcohol/tobacco on premises; no physician medical certification on-site for registry cards.
    • Plant waste transfers to disposers allowed; cannot transport plant waste themselves.

  • Safety compliance facilities (Sec. 505):

    • Authorized to take, test, and return marihuana to facilities; permissible to collect random samples for testing.
    • Must be accredited; others restrictions apply on ownership interests.
    • Must test for pesticide residues, cannabinoids, microbial content, mycotoxins, and other GMP-related metrics; must maintain secure lab space and staff with advanced degrees.
    • Plant waste transfers to disposers allowed; cannot transport plant waste.

Affected entities

  • Growers, processors, provisioning centers, secure transporters, and safety compliance facilities operating under Michigan’s medical marihuana regime.
  • Marihuana disposers (new/explicit role for waste disposal) and agents.
  • Law enforcement and state agencies via the statewide monitoring system and reporting requirements.
  • Property owners hosting licensed facilities (with protections for owners who are not aware of violations).
  • Financial institutions and service providers, given protections for providing financial services to licensees.

Procedural and timeline aspects

  • Rulemaking: CRA to issue rules and emergency rules as needed to implement the act, with rules to be established for waste disposal, facility operations, testing, labeling, marketing, and safety.
  • Tie-in: The bill is designed to tie with HB 6162 (as indicated in the title) for broader regulatory alignment.
  • Effective date: Enacting section notes that the act does not take effect unless HB 6162 is enacted into law. Specific implementation dates for new licensing rules and system changes would follow the act becoming law and the CRA publishing regulations.

Summary of potential impact

  • Strengthened regulation and oversight of marihuana plant waste handling and disposal, including explicit transportation rules for plant waste.
  • Expanded compliance requirements for all license categories, with enhanced recordkeeping and use of the statewide monitoring system to track waste and product movements.
  • Enhanced safety and quality controls for products, including testing standards and labeling requirements.
  • Additional operational considerations for in-location transfers to reduce roadway transport when feasible, potentially lowering public road traffic exposure.
  • Clearer penalties and protections under the act for licensees complying with rules, while maintaining enforcement through CRA rules and environmental protections.
