The Board shall establish a testing program for marijuana and marijuana products. Except as otherwise provided in this subtitle or otherwise provided by law, the program shall require a licensee, prior to selling or distributing marijuana or a marijuana product to a consumer or to another licensee, to submit a representative sample of the marijuana or marijuana product, not to exceed an amount of the total harvest or batch as established by the Board, to a licensed marijuana testing facility for testing to ensure that the marijuana or marijuana product does not exceed the maximum level of allowable contamination for any contaminant that is injurious to health and for which testing is required and to ensure correct labeling. The Board shall adopt regulations (i) establishing a testing program pursuant to this section; (ii) establishing acceptable testing and research practices, including regulations relating to testing practices, methods, and standards; quality control analysis; equipment certification and calibration; marijuana testing facility recordkeeping, documentation, and business practices; disposal of used, unused, and waste marijuana and marijuana products; and reporting of test results; (iii) identifying the types of contaminants that are injurious to health for which marijuana and marijuana products shall be tested under this subtitle; and (iv) establishing the maximum level of allowable contamination for each contaminant.
