Current law says that if municipal officials want to stop a particular type of establishment for example, marijuana cultivation facilities or all retail pot establishments, they must go to their voters. Local officials also need to hold a referendum if they want to sharply limit the number of marijuana shops. If a city has 100 retail stores that sell alcohol, for example, it will need to go to voters if it wants fewer than 20 marijuana retailers. But the powerful Massachusetts Municipal Association wants lawmakers Marijuana Stocks to amend the statute so a community doesnt have to hold a referendum to restrict pot facilities. Local legislative bodies, such as the Boston City Council, should have final say on whether or how many pot shops can come to town, just like they do over other major zoning decisions, said Geoffrey C. Beckwith, the associations executive director and chief executive. Jehlen disagrees. She supports clarifying the specifics of how communities can put such questions to a vote, but wants to leave the laws structure in place. I dont think it needs to be any easier; I think it needs clarification, she said. Her reasoning: If the law makes it too easy for a municipality to prohibit pot shops, the black market never goes away. She pointed to Colorado, where counties had to opt in to having pot shops, and about two-thirds declined.
