Maine lawmakers have given final approval to legislation that would revise testing requirements for adult-use marijuana products, sending the measure to Governor Janet Mills for her signature.
LD 1488, sponsored by State Senator Michael Tipping (D), was approved by both chambers following the adoption of several amendments that narrowed the bill’s original scope. The final version focuses exclusively on adult-use marijuana testing requirements.
As amended, the bill clarifies that using marijuana concentrates in the production of edible marijuana products does not constitute additional “processing” — a designation that would otherwise trigger separate testing requirements. Products would still be required to undergo standard testing for potency, homogeneity, and cannabinoid profile to ensure accurate labeling for consumers.
Lawmakers stripped earlier provisions addressing broader manufacturing and regulatory issues, keeping the legislation tightly focused on testing-related changes.
The Maine Senate approved the measure 26-8, with the House subsequently concurring before sending it to the governor’s desk. (RELATED: Flip-Flop Or Political Play? Governor Mills Embraces Millionaires Tax She Once Opposed Amid Senate Primary Bid)
If signed into law, the changes are expected to streamline the testing process for certain marijuana products while preserving existing consumer safety and labeling accuracy requirements. The bill would apply to Maine’s adult-use marijuana market, which has grown significantly since voters approved legalization in 2016.
Governor Mills has not yet indicated whether she will sign the measure.
