BOSTON (AP) — Massachusetts marijuana regulators have scheduled a vote on the licensing of two independent testing labs, which if approved could move the state closer to its first recreational pot sales.

License applications from CDX Analytics, of Salem, and MCR Labs, of Framingham, are on the agenda for Thursday's meeting of the Cannabis Control Commission.

The panel has already approved retail licenses for several medical marijuana dispensaries, but none can begin selling recreational marijuana products until they're tested for potential contaminants by a licensed independent lab.

It's among several factors that have been holding up the opening of retail pot shops in Massachusetts, something that had originally been supposed to happen around July 1.

The state's voters legalized recreational marijuana for adults in November 2016.
