Mass. and Cass

Mass. and Cass, also known as Methadone Mile or Recovery Road, is an area in Boston, Massachusetts, located at and around the intersection of Melnea Cass Boulevard and Massachusetts Avenue. Due to its concentration of neighborhood services providing help, the area around Mass. and Cass has long attracted a large number of people struggling with homelessness and drug addiction, especially after the closure of facilities on Long Island in Boston Harbor. It has been characterized as "the epicenter of the region's opioid addiction crisis".

It was, for many years, a tent city and open air drug market. The tents were removed in the fall of 2023. As of September 2024, the tents were mostly gone but it was still a gathering place for the homeless and drug users. It is located in the area of Newmarket, an industrial part of Boston that includes some of Dorchester, South Boston, Roxbury, Boston, and the South End.
