B. Staggered implementation:

(1) The division may within its discretion delay implementation of sample collection and testing requirements of this section, in whole or in part.

(2) In determining the start date of an individual testing requirement, the division shall consider whether a cannabis testing laboratory has validated a method for conducting the test.

(3) In determining the date on which a cannabis establishment must have its samples collected by an employee or contractor of a cannabis testing laboratory, the division shall consider the capacity of cannabis testing laboratories to collect and transport samples.

(4) The division may establish different implementation dates for sample collection requirements for:

(a) cannabis producer microbusinesses and integrated cannabis microbusinesses located up to 100 miles by automobile from the nearest licensed cannabis testing laboratory location;

(b) cannabis producers, cannabis manufacturers, and vertically integrated cannabis establishments located up to 200 miles by automobile from the nearest licensed cannabis testing laboratory location;

(c) cannabis producer microbusinesses and integrated cannabis microbusinesses located more than 100 miles by automobile from the nearest licensed cannabis testing laboratory location;

(d) cannabis producers, cannabis manufacturers, and vertically integrated cannabis establishments located more than 200 miles by automobile from the nearest licensed cannabis testing laboratory location; and

(e) cannabis establishments for which travel to a licensed cannabis testing laboratory location requires passing through a United States border patrol checkpoint.

C. Collection and transportation of samples: A cannabis testing laboratory is responsible for the collection of samples for the performance of any required test, re-test after a failing result, re-test after remediation, or test for the purposes of labeling.

(1) A cannabis testing laboratory may perform sample collection using:

(a) Laboratory employees with requisite training, as specified in 16.8.2.26 NMAC; or

(b) Contractors who have completed the sampling agent training offered by the U.S. department of agriculture’s domestic hemp production program and sign an affidavit that they have no ownership interest in, and are not employed by, any cannabis establishment that produces or manufactures cannabis. The contractor shall obtain necessary training to comply with the cannabis testing laboratory’s protocols, and the cannabis testing laboratory may reject any sample that it suspects was collected outside of its protocols.

(2) A cannabis testing laboratory may transport samples using:

(a) Laboratory employees with requisite training, as specified in 16.8.2.26 NMAC; or

(b) Contractors who sign an affidavit that they have no ownership interest in, and are not employed by, any cannabis establishment that produces or manufactures cannabis. Transporting cannabis for a cannabis establishment on a contractual basis does not preclude a person or entity from transporting samples in secure containers for cannabis testing laboratories.

(3) Nothing in these rules shall be interpreted to require a cannabis testing laboratory to collect samples from or transport samples on behalf of any cannabis establishment.

(4) If the division has delayed implementation of the requirement that the cannabis testing laboratory collect the sample from a cannabis establishment, based on its distance from the nearest cannabis testing laboratory or location beyond a U.S. border patrol checkpoint, then any person collecting or transporting samples for required testing must receive training in sample collection and transportation protocols.

(a) Nothing in these rules shall be interpreted to require a cannabis testing laboratory to accept samples from a cannabis establishment.

(b) The cannabis testing laboratory may reject any sample that it suspects was collected outside of its protocols.

(5) A cannabis establishment may specify reasonable precautions prevent the contamination of batches of cannabis, except that the cannabis establishment must provide access to the entire batch of cannabis product. Precautions may include, but are not limited to:

(a) requiring the use of gloves and other personal protective equipment

(b) inspecting tools and containers prior to their use;

(c) specifying the location within the cannabis establishment at which the samples will be collected;

(d) specifying locations within the cannabis establishment to which laboratory employees or contractors do not have access; and

(e) the right to refuse entry to any laboratory employee or contractor not in compliance with the precautions

(6) Nothing in these rules shall be interpreted to require routine testing of cannabis products before the cannabis establishment segregates cannabis products into batches and places the batches into containers for storage while awaiting test results.

D. Compliance with all rules and applicable laws required: Passage of testing does not relieve an establishment of its obligation to comply with the Cannabis Regulation Act, the Lynn and Erin Compassionate Use Act, the Pesticide Control Act, division rules, or other local, state, and federal laws not in conflict with the Cannabis Regulation Act or the Lynn and Erin Compassionate Use Act.

(1) A cannabis establishment shall waste and dispose of any cannabis product to which a pesticide has been applied in violation of division rules or the Pesticide Control Act or any product manufactured using an unapproved solvent.

(2) Nothing in this rule shall be interpreted as precluding regulatory activities by other state agencies that do not conflict with the Cannabis Regulation Act or the Lynn and Erin Compassionate Use Act.

E. Exceptions to required testing:

(1) A cannabis establishment shall not be required to have tested for pesticide residue any cannabis product made from cannabis concentrate or cannabis extract with verified pesticide residue test results, so long as the establishment can demonstrate that the resulting product will not exceed action levels for that type of cannabis product.

(2) A cannabis establishment shall not be required to have tested a cannabis product acquired from another cannabis establishment if the batch, in present form, was previously determined to have passed the testing requirements of this rule and is accompanied by a Certificate of Analysis issued by a licensed cannabis testing laboratory within the previous ninety days.

(3) If additional testing requirements take effect after a cannabis testing laboratory obtains a sample of a cannabis product for required testing, the laboratory is required to perform only those tests required at the time the sample was obtained.

F. Visual inspection: A sample shall pass visual inspection if, under a minimum of 40X magnification, laboratory personnel detect in a one gram sample:

(1) no living or dead insects, hair, eggs, or feces; and

(2) no more than two percent sand, soil, mold, or rocks.

G. Microbiological testing: A sample shall pass microbiological testing if the sample contains concentrations of target microbes not exceeding the action levels set forth in Table 2, Microbiological Testing Requirements, below.

(1) The division may require required testing for additional microbes if quality control or inspection testing conducted by cannabis testing laboratories, NMDA, the department of health, or the division identifies their presence, in a quantity or amount that poses a threat to public health, in a cannabis product produced, manufactured, or sold by any cannabis establishment. The division shall provide written notice to licensees 30 days before requiring required testing for additional pesticide residues, except that such notice is not required when human illness is linked to contaminated cannabis products.

(2) The cannabis testing laboratory may report a collective total of the four Aspergillus strains listed without distinguishing individual totals.

(3) The test results shall be reported as “Present,” “Absent,” or in colony forming units (CFU) per one gram sample.

I. Potency and homogeneity testing:

(1) Potency testing requires determining the quantity of tetrahydrocannabinol (THC), tetrahydrocannabinolic acid (THCA), cannabidiol (CBD), cannabidiolic acid (CBDA) per gram of sample and the calculation of THC potency and CBD potency, according to Table 4, Potency Testing Requirements, below.

(2) Batch-level homogeneity testing is performed by testing for total THC potency. The number of samples to be tested shall be based on the size of the batch according to the method validated by the cannabis testing laboratory; however, the total number of samples tested shall be not less than three for any batch of material five pounds or less.

(3) Product-level homogeneity testing is performed by segregating a single retail package or an identical quantity of a solid or semi-solid and testing for total THC potency a minimum of three randomly selected increments of the product.

(4) A set of samples shall pass homogeneity testing if the relative standard deviation of total THC potency of the samples is no more than twenty percent.

K. Release of batch after testing: A cannabis establishment may release an entire batch of cannabis product for immediate manufacture, sale, or other use, provided that the sample taken from the batch passes the tests required in this section.

L. Procedures for testing: A cannabis establishment shall adhere to the following procedures:

(1) After collection of samples, a batch of cannabis product shall be segregated in a secure container and stored under controlled environmental conditions (temperature, humidity, light) designed to limit microbial growth or other spoilage until the cannabis establishment receives a certificate of analysis indicating the batch meets the testing requirements of this rule.

(2) The secured container shall be labeled with the identification number used in the track and trace system, the name of the cannabis testing laboratory, the date on which the samples were taken, and, in minimum 12-point font, all capital letters, “AWAITING TEST RESULTS. DO NOT TRANSER.”

(3) The cannabis testing laboratory and the cannabis establishment submitting samples each shall appropriately document in the track and trace system the sampling and testing of cannabis product.

(4) A cannabis establishment shall maintain all results of laboratory tests conducted on cannabis products produced or manufactured by the cannabis establishment for a period of at least two years and shall make those results available to consumers or cannabis retailers upon request.

M. Re-testing: If a sample fails any test, the cannabis establishment may request re-testing by the same cannabis testing laboratory or another cannabis testing laboratory. If the repeated test is within acceptable limits, then the batch may be sold, transferred, or further manufactured.

N. Remediation: Within 120 days of a failed test, a cannabis establishment may remediate and retest the batch according to the procedures described in this subsection. A cannabis establishment shall adopt and maintain on the premises protocols regarding remediation consistent with this rule.

(1) A cannabis establishment may remediate dried cannabis or cannabis concentrates that fail microbiological testing by means of extraction using an approved volatile solvent. Other products that fail microbiological testing may not be remediated.

(2) A cannabis establishment may remediate any cannabis product that fails homogeneity testing through any approved manufacturing process, including extraction, chopping, melting, mixing, infusing, or otherwise combining the batch.

(3) A cannabis establishment may remediate any cannabis product that fails residual solvent testing by evaporating solvent using heat, vacuum pressure, or a combination of methods.

(4) A cannabis establishment may remediate cannabis that fails visual inspection for the presence of mold by means of extraction using an approved volatile solvent.

(5) A cannabis establishment may remediate cannabis that fails visual inspection for the presence of insects, hair, eggs, or feces by removing the contaminants, followed by extraction using an approved volatile solvent.

(6) A cannabis establishment may remediate cannabis that fails visual inspection for the presence of soil or rocks by removing the contaminants.

(7) Cannabis product that has been remediated must undergo any test that was previously failed.

(8) Cannabis product that has been remediated with the use of volatile solvents must additionally undergo residual solvent testing.

O. Notice and destruction: Any cannabis product that fails a test and cannot be remediated, including any remediated cannabis product that fails any test after remediation, is subject to destruction in accordance with the wastage requirements of 16.8.2.15 NMAC. The cannabis establishment shall notify the division within 24 hours and shall confirm the wastage and disposal of the usable cannabis in accordance with this rule. The wasted product shall be removed from inventory, and the removal from inventory shall be noted in the track and trace system.

P. Interpretation of differing results: Results produced by a cannabis testing laboratory are valid only for the sample tested. A differing result produced by quality control or inspection testing of a different sample pursuant to 16.8.2.16 NMAC is not grounds for action against the cannabis testing laboratory that produced the original testing result.

[16.8.7.8 NMAC – N, 03/01/2022]
