Basis and Purpose - 4-115
The statutory authority for this rule includes but is not limited to sections 44-10-202(1)(c), 44-10-203(1)(a), 44-10-203(1)(c), 44-10-203(1)(g), 44-10-203(1)(k), 44-10-203(2)(d), 44-10-203(2)(f), 44-10-203(3)(d), 44-10-203(3)(e), 44-10-501(6), 44-10-502(3), 44-10-503(8), 44-10-504(1)(b), 44-10-504(2), 44-10-601(4), 44-10-602(4), 44-10-603(6), 44-10-604(1)(b), and 44-10-604(2), C.R.S. Authority also exists in the Colorado Constitution at Article XVIII, Subsection 16(5)(a)(VII). The purpose of this rule is to establish the portion of the Division's mandatory testing and sampling program that is applicable to Regulated Marijuana Businesses, and specifically Medical Marijuana Testing Facilities and Retail Marijuana Testing Facilities. While the Marijuana Code requires the State Licensing Authority to establish acceptable limits of potential contaminants, it also requires the State Licensing Authority to enact a plus or minus 15 percent potency variance, which is also included in this rule. This Rule 4-115 was previously Rules M and R 712, 1 CCR 212-1 and 1 CCR 212-2.
