Massachusetts is about to become home to the largest cannabis cultivation center in the United States. In October, Denver-based AmeriCann (OTC: ACAN) purchased a 53-acre production facility from Boston Brewing Company (NYSE: SAM) for $4.5 million in cash. Today, ACAN is in the early stages of building a 1.1 million square foot cultivation facility that will be the largest in the United States. The bold move comes at a great time. Massachusetts and Maine both voted to legalize recreational cannabis in November. This production facility should position ACAN to be a major supplier to the North East cannabis market.
