CommCan – The Commonwealth Cannabis Co. – is a Massachusetts registered marijuana dispensary with state and local approvals to operate in the communities of Medway, Millis, Mansfield and Southborough. CommCan is Massachusetts’​ premier “home grown”​ cannabis company, financed, owned and operated by lifelong Massachusetts residents. CommCan’s home is the largest new-construction marijuana cultivation facility in Massachusetts. Solar powered, climate controlled with a fully automated well-water fed irrigation and fertigation system, our plants are exposed to only perfect growing conditions every day of their lives. This is possible because we designed and built this world class facility from the ground up. Construction of our 60,000 sq/ft building was completed in November 2017.
