Maine lawmakers have given final approval to a bill that would revise how marijuana products are tested, sending the measure to Governor Janet Mills for consideration.

LD 1488, sponsored by State Senator Michael Tipping (D), was approved by both the House and Senate following the adoption of multiple amendments that reshaped the proposal’s scope. The final version focuses specifically on adult-use marijuana testing requirements.

As amended, the bill clarifies that the use of marijuana concentrates in the production of edible marijuana products does not count as additional “processing” that would otherwise trigger separate testing requirements. Instead, these products would still need to undergo standard testing for potency, homogeneity and cannabinoid profile to ensure accurate labeling.

Lawmakers also removed earlier provisions that would have addressed broader manufacturing and regulatory issues, narrowing the legislation to testing-related changes.

The Senate approved the measure by a vote of 26 to 8, with the House subsequently concurring and sending it to the governor’s desk.

If signed into law, the changes are expected to streamline aspects of the testing process for certain marijuana products while maintaining existing requirements tied to product safety and labeling accuracy.
