BOSTON - The lack of any licensed independent testing laboratories for recreational marijuana remains a key stumbling block to opening pot shops in Massachusetts.
The state's Cannabis Control Commission holds its next meeting Thursday but has yet to receive any completed applications for testing facilities.
Massachusetts requires all marijuana products sold commercially to bear a seal showing they've been independently tested for contaminants.
The state targeted July 1 for the start of recreational marijuana sales but that has yet to happen.

Three laboratories have been registered by state health officials to test medical marijuana, but they must apply for a separate license from the CCC to test for the retail market.
One of them, MCR Labs of Framingham, says it hopes to complete its application and begin testing recreational marijuana within weeks.
