Minn. R. 4770.3030 - POTENCY TESTING OF DRIED RAW CANNABIS
Subpart
1.
Cannabinoid content.
A. Before being packaged, a representative
sample from each batch of dried raw cannabis must be tested to establish the
concentration of cannabinoid analytes, reported as the percentage content by
weight for:
(1) Delta-9-tetrahydrocannabinol
(THC);
(2)
Delta-9-tetrahydrocannabinolic acid (THCA);
(3) Cannabidiol (CBD); and
(4) Cannabidiolic acid (CBDA); and
(5) any other cannabinoid determined by the
commissioner.
B. The
commissioner must maintain a list on the Office of Medical Cannabis website
(http://mn.gov/ medicalcannabis) of all
cannabinoids required to be analyzed by the testing laboratory. In addition to
publication on the Office of Medical Cannabis website, updates to the list must
be communicated by e-mail to each registered manufacturer and to each approved
laboratory.
C. In addition, the
testing laboratory must calculate and report the total THC content and total
CBD content:
(1) Total THC content is
calculated:
Total THC = %THC + (%THCA x 0.877).
(2) Total CBD content is calculated:
Total CBD = %CBD + (%CBDA x 0.877).
Subp. 2.
Triple
preparation; sample potency.
A. The
testing laboratory must use a triple preparation to determine the potency of
the sample. If multiple preparations are used, the reported potency must be the
mean value of the results. The relative standard deviation between the tested
samples must be ten percent or less.
B. The testing laboratory must notify in
writing both the manufacturer and the commissioner if it requires a sample of
more than two grams of dried raw cannabis to conduct the testing before the
testing begins.
