Chapter 6. Testing Laboratories

Article 5. Laboratory Testing and Reporting

§15719. Residual Pesticides Testing.

  1. (a) The licensed laboratory mustshall analyze at minimum 0.5 grams of the representative sample of cannabis and cannabis products to determine whether residual pesticides are present.
  2. (b) The licensed laboratory mustshall report whether any Category I Residual Pesticides are detected above the limit of detection (LOD) and shall report the result of the Category II Residual Pesticides residual pesticide testing in unit micrograms per gram (μg/g) on the COA. The laboratory mustshall indicate “pass” or “fail” on the COA.
  3. (c) Until April 1, 2028:

    1. (1) For each pesticide listed in Table 1 below, the The licensed laboratory mustshall establish a limit of quantitation (LOQ) of 0.10 μg/g or lower for all Category I Residual Pesticides at or below the indicated action level for that pesticide.
    2. (d)(2) A sample passes residual pesticide testing if pesticide residues found in the sample do not exceed the indicated action levels in Table 1 below. The sample shall be deemed to have passed the residual pesticides testing if both of the following conditions are met:

  4. (d) Beginning April 1, 2028:

    1. (1) For each pesticide listed in Table 2 below, the licensed laboratory must establish an LOQ as follows:

      1. (A) At or below 0.10 μg/g if the action level is ≥0.10 μg/g.
      2. (B) At or below the indicated action level if the action level is <0.10 μg/g.

      (2) A sample passes residual pesticide testing if pesticide residues found in the sample do not exceed the indicated action levels in Table 2 below.

    2. (1) The presence of any residual pesticide listed in the following tables in Category I are not detected, and
    3. (2) The presence of any residual pesticide listed in the following tables in Category II does not exceed the indicated action levels.

    5. (e) If the sample fails residual pesticide testing, then the batch from which the sample was collected fails residual pesticide testing and may not be released for retail sale.

§15731. Limits of Detection (LOD) and Limits of Quantitation (LOQ) for Quantitative Analyses.

  1. (a) The licensed laboratory shall must calculate the LOD for chemical method analyses according to any of the following methods: using the standard

    1. (1) Signal-to-noise ratio of between 3:1 and 2:1;
    2. (2) Standard deviation of the response and the slope of calibration curve using a minimum of 7 spiked blank samples calculated as follows;
      LOD
      =
      (
      3.3
      x
      standard deviation of the response
      )
      /
      slope of the calibration curve

      .; or

    3. (3) A method published by the United States Food and Drug Administration (USFDA) or the United States Environmental Protection Agency (USEPA).
  2. (b) For chromatographic analyses, the LOD must have a minimum signal-to-noise ratio of 3:1, which must be verified by visual inspection. For non-chromatographic analyses, the LOD must have a minimum signal-to-noise ratio of 3:1, which must be verified by software analysis or mathematical calculation.
  3. (c) The licensed laboratory shall must calculate the LOQ for chemical method analyses according to any of the following methods: using the standard

    1. (1) Signal-to-noise ratio of 10:1, at minimum;
    2. (2) Standard deviation of the response and the slope using a minimum of 7 spiked blank samples calculated as follows:
      LOQ
      =
      (
      10
      x
      standard deviation of the response
      )
      /
      slope of the calibration curve

      .; or

    3. (3) A method published by the USFDA or the USEPA.
  4. (d) For chromatographic analyses, the LOQ must have a minimum signal-to-noise ratio of 10:1, which must be verified by visual inspection. For non-chromatographic analyses, the LOQ must have a minimum signal-to-noise ratio of 10:1, which must be verified by software analysis or mathematical calculation.
