About five weeks since the first non-medical marijuana stores opened in Massachusetts, the chairman of the Cannabis Control Commission said it is still too early to determine what, if any, changes need to be made to the law or regulations.

During a Monday appearance on Boston Herald Radio, CCC Chairman Steven Hoffman said the five retail marijuana stores now open are doing “blockbuster business,” but the only thing that can be determined for sure about the fledgling industry is that the drug is in high demand.

“The daily and weekly [sales] totals haven’t trickled down, they’re pretty much constant at a high level and the lines at places like NETA in Northampton really haven’t diminished much as far as we’ve been able to tell,” he said. “It’s strong demand but with five stores open it’s just too early to form any judgments other than there’s a lot of demand out there.”

Hoffman said the CCC is in a “rhythm” now that could result in four to eight new retail stores coming online each month. He said the industry will look “more mature” in a few months and said the CCC will discuss at its Jan. 10 meeting a timeline to review and possibly revise the regulations that govern the adult-use and medical marijuana programs in 2019.

“To the extent that we make any changes to our adult-use regs they will be tweaks, things that we just didn’t quite get right,” he told Herald Radio host Hillary Chabot. “I don’t foresee major changes to those regulations.”
