After taking weeks to come together, a six-person conference committee is now fully in place and ready in the new year to begin hashing out final details of Massachusetts legislation overhauling cannabis laws.

The Senate on Wednesday assigned Sens. Adam Gomez of Springfield, Joanne Comerford of Florence and Peter Durant of Spencer as conferees. The House last week named Reps. Daniel Donahue of Worcester, Carlos Gonzalez of Springfield and Michael Soter of Bellingham as negotiators. Donahue and Gomez are co-chairs of the Committee on Cannabis Policy and will serve as the lead negotiators on behalf of their branches.

On Nov. 19, the Senate voted 30-7 to approve its cannabis bill (S 2749). The House passed its version (H 4206) on a 153-0 vote in June. The bills reconfigure the Worcester-headquartered Cannabis Control Commission in different ways and make other marijuana law changes. The conference committee will attempt to forge a consensus bill.

As negotiations begin, a proposed ballot initiative to repeal adult-use recreational marijuana is moving forward in the process. Also, the commission this month passed long-awaited regulations governing sites where people could consume marijuana products socially. The regulations are expected to be promulgated Jan. 2 and cities and towns must opt in to allowing social consumption businesses and develop their own standards of practice.

Both chambers’ bills remove the treasurer’s appointing authority and shrink the Cannabis Commission from five members to three. Under the Senate bill, two members would be appointed by the governor and one by the attorney general. The House bill would give the governor full control over commission appointments.

Both bills also raise the amount of marijuana a person can legally possess from one to two ounces.
