Minnesota Marijuana Testing License

Does Minnesota Require Testing for Marijuana and Marijuana Products?

Yes, the State of Minnesota requires manufacturers of medical marijuana products to test all their products before making them available for public consumption. Section 9(b) of the Minnesota Session Laws-2014 requires manufacturers of medical marijuana to contract with marijuana testing laboratories to test products manufactured for public consumption. Medical marijuana products in Minnesota are required to be tested to:

  • Ascertain what the product contains
  • Ascertain that they do not contain contaminants
  • Ascertain that they are consistent with the state’s requirement for medical cannabis. Subdivision 6 of the Minnesota Statutes 2020 defines medical marijuana as any of the species of the genus cannabis plant, their mixture, preparation, whole plant extract, or resins packaged for consumption in any of the following forms:
    • As oil, or other forms of liquid
    • As pill
    • As a vaporized delivery product that can be used with oil or other forms of liquid, this excludes dried marijuana leaves or other plant forms.
    • As any form or package of marijuana suitable for medical uses, excluding smoking, however, the forms must be approved by the Minnesota Commissioner of Health.

Section 4770.0550 of the draft rules regulating medical cannabis laboratory requirements in Minnesota require all medical marijuana products to undergo the following tests and for the following reasons:

  • General testing: The Minnesota Department of Health requires manufacturers of medical marijuana products to submit documents defining the content of each of their finished goods to the Commissioner for Health. This will be compiled in the registered finished goods list of the Minnesota Department of Health. The marijuana testing laboratory that took the test must complete a final test report after conducting the test on the samples. The testing facility must include a description of the tests they conducted, the methods used, and the results obtained from the tests. These must be included in the final report and forwarded to the Minnesota Commissioner for Health and the manufacturer.

  • Safety testing: The Minnesota Department of Health requires that a medical marijuana product formulation passes safety testing conducted by an approved third-party laboratory. A full spectrum safety testing must be conducted to determine all substances in the product. This must be done before a product formulation can be used to formulate a finished good.

  • Contaminant testing: Contaminant testing focuses on the presence of some specific analytes and their concentration. Here are the focus contaminants in medical marijuana products and the maximum acceptable concentration.

    • Metals
      • Arsenic: 1.5 ppm (ppm is parts per million)
      • Cadmium: 0.3 ppm
      • Lead: 1 ppm
      • Mercury: 0.5 ppm
    • Toxins
      • Aflatoxin B1: 5ppb (ppb is parts per billion)
      • Aflatoxin B2, Aflatoxin G1, and Aflatoxin G2: There is no specific maximum limit for each of these three toxins, but the concentration summation of three must not exceed 15 ppm)
    • Microbials
      • Salmonella: must be absent
      • E. coli: 7 CFU/g (CFU is Colony Forming Units)
      • Mould and Yeast: 1000 CFU/g
      • Aerobic Bacteria:100000 CFU/g
      • Bile tolerant gram-negative bacteria: 150 CFU/g
    • Solvents
      • Pentane: 3000ppm
      • N-hexane: 290ppm
    • Pesticides: The manufacturer of a medical marijuana product must inform the marijuana testing laboratory if they used pesticides in the production process of the marijuana. The maximum concentration of pesticide in the product depends on the pesticide named by the manufacturer.
  • Potency testing: The Minnesota Department of Health requires that potency testing be conducted on all medical marijuana products in the state. The permissible potency variance for product contents measured by mg of cannabinoid/product weights are as follows:

    • Primary cannabinoids: +/-10%
    • Secondary cannabinoids: +/-25%
    • Cannabinoids found in trace amounts do not have a potency limit except for tetrahydrocannabinol (THC) and tetrahydrocannabinolic acid (THCA). Cannabinoids found in trace amounts should be less than 1% of the total cannabinoid content, and they are required to be listed in the final testing report.
  • Stability testing: The Minnesota Department of Health requires that stability tests be conducted on every batch of medical marijuana products produced in the state. This is to ascertain that the product will be safe and effective until its expiration. The test must be conducted before the product is released to the market (the initial time). The test must also be conducted every three months for the first twelve months after the initial time and every six months after the first twelve months.

Does Minnesota License Independent Marijuana Testing Facilities?

Yes, the Minnesota Department of Health licenses independent marijuana testing facilities to ascertain the safety of medical marijuana products for human consumption. Medical marijuana testing laboratories can apply for licenses anytime as the license application is open all through the year. There are two independent medical marijuana laboratories approved in Minnesota. The state does not have a government agency conducting medical marijuana testing.

What Accreditations Do Marijuana Testing Facilities Need in Minnesota?

The Minnesota Department of Health requires all approved medical marijuana testing facilities in the state to have an ISO/IEC 17025 accreditation. In the Sales of Certain Cannabinoid Products Workgroup Report, medical marijuana manufacturers and growers must perform sampling and testing according to the ISO/IEC 17025 standard. The ISO/IEC accreditation is a formal recognition of the competence of a testing laboratory granted by the American National Standards Institute (ANSI) National Accreditation Board. The accreditation can be obtained when a testing laboratory meets the laboratory operation standards of the board. Laboratory test results obtained from an ISO/IEC accredited laboratory are deemed reliable.

The American National Standards Institute (ANSI) National Accreditation Board requires marijuana testing facilities to:

  • Submit a document showing how the testing laboratory plans to perform representative sampling of all activities specified within the scope of the accreditation for a period not less than three years. The document submitted is expected to contain an evaluation of the possible risks associated with the processes of laboratory operations. Planned procedures to curtail these risks are also expected to be contained in the document.
  • Prove to the ANSI National Accreditation Board their commitment to investigate any test results that fall outside of the predefined performance range. Actions expected of a marijuana testing facility in situations of unsatisfactory results include:
    • The marijuana testing laboratory shall promptly notify the ANSI National Accreditation Board of any case of unsatisfactory results. The notification to the board can be done through email, using the ANAB FM 2830 Client Notification form.
    • The testing facility shall have a documented time frame within which corrective actions will be taken in cases of unsatisfactory results.
    • The testing facility shall have a record of the summary of all cases of unsatisfactory results. This shall consist of a briefing on the investigation and conclusion of all cases of bad results that occurred in the testing laboratory.
  • Participate in proficiency testing (PT)/Inter-laboratory comparison(ILC), covering the processes defined in the scope of the accreditation. These include test technologies and other parameters. The term proficiency testing (PT) evaluates participants’ performance as they relate to established criteria.
