ME LD104

Establishes mandatory testing program for medical cannabis requiring all harvested cannabis be tested for contaminants (pesticides, metals, molds, harmful microbes, residual solvents) and cannabinoid profiles before sale to qualifying patients

Creates registration requirements for cannabis testing facilities, which must either hold a license under the adult-use cannabis program or obtain ISO/IEC 17025 accreditation and Maine CDC certification

Specifies different testing requirements based on product type (matrix): cannabis flower/trim, solvent-extracted concentrates, solventless concentrates, and cannabis products each have distinct mandatory testing panels

Requires registrants to submit inventory tracking information to a statewide system by 11:59 p.m. daily, including complete inventory records and all mandatory test results, with records retained for 6 years (increased from 4 years)

Allows cannabis testing facilities licensed under the adult-use program to receive no-fee registration certificates to also test medical cannabis, streamlining operations across both markets
