Lawrence Davis-Hollander cited potential security requirements as an issue. And he pointed to one rule, which would require all aspects of cultivation take place out of the public eye.

“In comparison, what are the security requirements for liquor stores, for pharmacies, for tobacco?” Davis-Hollander said. “Do we hide tobacco, a toxic substance, a deadly substance, out in the fields? No, we don’t.”

Brandon Pollock heads Berkshire County’s only medical marijuana dispensary. He said he disagrees about one draft regulation — which would require a physical barrier between where medical and recreational purchases would take place.

“If companies have to build out separate demising walls, separate entrances just to serve patients, market forces will, I would presume, lead to some companies not serving patients anymore,” Pollock said.

The commission is also taking comments in writing through the middle of February, and must have final regulations ready by mid-March.
