This is an artist rendering of Haven, a recreational marijuana retailer applying to open in Southwick. “We can’t wait to get it open,” said Mark S. Dupuis, who co-owns the business with Brian Kuchachick. She has a fundamental understanding of the business,” Dupuis said of Hildebrandt. Maura Healey signed new legislation that restructured the CCC and eased restrictions on medical marijuana retailers, such as eliminating the requirement that medical marijuana businesses grow and process the cannabis they sell, according to the governor’s office. Dupuis said Kuchachick recently became affiliated with a 100,000-square-foot grow operation, which will factor into the products Haven offers.
