2-23-3.1. Determination of delta-9-THC concentrations.

For purposes of this chapter, delta-9-THC concentration shall be established by:#

1. (1)

   Identifying the total percentage weight, on a dry weight basis where applicable, of delta-9-THC from a sample that has undergone decarboxylation such that all delta-9-THCA in the sample has been converted to delta-9-THC; or#

2. (2)

   Identifying the sum of the percentage by weight, on a dry weight basis where applicable, of delta-9-THCA multiplied by 0.877 plus the percentage by weight, on a dry weight basis where applicable, of delta-9-THC.#

For purposes of this chapter, when determining whether a tested sample of hemp or hemp products has a total delta-9-THC concentration that exceeds or is within the legal limit, such determination shall take into account the applicable measurement of uncertainty for the test used to establish the total delta-9-THC concentration. The department, by rules or regulations, may specify the method and procedure for determining the applicable measurement of uncertainty for a given test used to determine the total delta-9-THC concentration of a sample of hemp or hemp products.#
