Pennsylvania Marijuana Testing License

Does Pennsylvania Require Testing for Marijuana and Marijuana Products?

The State of Pennsylvania requires all medical marijuana and medical marijuana products produced and sold in the state to be tested to ascertain that:

There are no harmful contaminants in the product
The labels on the packaging of the products accurately reflect the content and the concentration of the active components of the medical marijuana products.

Section 29(C) of Title 28, Chapter 1171 of the Pennsylvania Code mandates that prescribed tests by the Pennsylvania Department of Health are performed by approved laboratories. The prescribed tests by the Pennsylvania Department of Health include tests of samples from:

A harvest batch or harvest lot before they are used for the production of medical marijuana products.
Medical marijuana products from either a harvest batch or a harvest lot before they are offered for sale to other medical marijuana organizations.

The Pennsylvania Department of Health provides a guide for quality testing and sampling by approved laboratories. The guide requires harvest batches, harvest lots, and production batches of medical marijuana products in Pennsylvania to do a chemical profile and contaminant analysis of the marijuana in their possession. Other tests for chemical profiles of marijuana and marijuana products include tests conducted on:

Terpenes
Pesticide residues
Residual solvents
Heavy metals
Moisture content and water activity
Significant microbiological contents.

Some of the significant contaminants in medical marijuana harvest and final medical marijuana products that require a chemical profile are:

Metals such as Arsenic, Cadmium, Lead, and Mercury
Mycotoxins such as Aflatoxin B1, Aflatoxin B2, Aflatoxin G1, Aflatoxin G2, and Ochratoxin A
Microbes such as Salmonella, E. Coli, Mold, and Yeast, Total viable Aerobic Bacteria
Bile tolerant gram-negative bacteria
Solvents such as Butane and Ethanol
Pesticides that are not among the list of acceptable pesticides published in the Pennsylvania Code.

The chemical profile of acceptable chemicals used by the Pennsylvania Pesticide Control Act will also be tested to ascertain that their presence in the marijuana is within acceptable limits. The Department of Health may also require samples for certain tests to be taken at different stages of the production of marijuana or marijuana products. Below are some tests and the points of sample collection for the tests required by the Department of Health.

What Accreditations Do Marijuana Testing Facilities Need in Pennsylvania?

Every medical marijuana testing facility in the State of Pennsylvania is required to obtain an ISO/IEC 17025 accreditation. Chapter 1171.23 (b)(4) of Title 28 of the Pennsylvania Code mandates prospective medical marijuana testing laboratories to submit copies of their most recent ISO/17025 certificates of accreditation with their applications. The ISO/IEC 17025 certificate is a document issued by the American National Standards Institute (ANSI) National Accreditation Board as evidence of compliance with required laboratory operation standards. It affirms that the testing facility is competent to carry out tests, calibrations, sampling, etc. It also affirms that the laboratory has a quality management system and that their test results are reliable.

To obtain an ISO/IEC 17025 accreditation, a medical marijuana testing facility will be required to:

Participate in appropriate proficiency testing (PT)/Inter-laboratory comparison (ILC) that represents the parameters, test technologies, and methods described in the scope of the accreditation. Proficiency testing is a term used to describe an evaluation of participants’ performance in relationship with established criteria using inter-laboratory comparisons.
Maintain a documented plan of how they want to ensure they carry out representative sampling of all activities identified in the scope of the accreditation for at least a minimum of three years. There must also be an evaluation of the risk associated with the scope of the accreditation, and the risk management plan should be incorporated in the proficiency testing plan.
Demonstrate a commitment to investigate test results that fall outside predefined performance criteria, such as unsatisfactory results. Some of the actions that the testing laboratory shall take are:
- Promptly notify the ANSI National Accreditation Board of the unsatisfactory result. This is typically done by sending an email to the board using the ANAB FM 2830 Client Notification form.
- Specify a stated time frame within which corrective actions shall be taken
- Maintain a record of the investigation summary and the conclusion on every case of unsatisfactory results.
Ensure that it is not the same staff that always undertakes performance testing activities for the testing laboratory if there are other qualified persons in the organization that can perform the same work.
