Pro-marijuana advocates have spent the last few weeks at the Massachusetts State House, waiting for lawmakers to emerge with a re-write of the pot law passed by voters in November.

But if there's an impasse and a re-write never makes it to Gov. Charlie Baker's desk, the advocates say they're okay with that, since that would mean the law they crafted is spared an overhaul.

State senators proposed a light re-write, while top lawmakers in the Massachusetts House are seeking more of a repeal-and-replacement of the law approved by 1.8 million voters.

A group of House-Senate negotiators have been meeting behind closed doors to reach a compromise, but they've blown their own deadline to get a bill to the governor by June 30.

"The way it's looking now - I have no insight into what's going on - my guess is that neither side is budging much and if nothing happens the law stays on the books as is," Jim Borghesani, spokesman for the group that worked to pass the legalization law, told reporters. "That's fine with us."

Under current law, the governor has to appoint an advisory group by August and the state treasurer must pull together a Cannabis Control Commission by September. Earlier this year, the governor and lawmakers approved a delay in retail pot shops, pushing their opening to July 2018.

Baker and the lawmakers said the delay was necessary because they needed to work on a larger re-write of the law approved by voters. Advocates would prefer no changes, but favor the Senate's proposed light touch.

But lawmakers have been unable to agree on what the re-write will entail, and differ on the tax rate and who gets a say in banning local pot shops.

Current law calls for an overall marijuana tax rate of 12 percent and voter referendums.

"At some point we are going to have to go forward with the law as it was written," Baker told reporters on Tuesday, according to the Associated Press.

"Remember, they can still make changes," Borghesani said while visiting the State House. "They can change this anytime. This idea that we have go get everything right out of the gate, it's not true. In fact we have the Cannabis Control Commission mandated to give legislative recommendations to the Legislature each year on taxes, on everything."
