The city of Chelsea, Massachusetts has a population of approximately 39,690 people, and is located in Suffolk County, just across the Mystic River from the city of Boston. This location means that a Chelsea methadone clinic can serve a large number of people, even though, at only 2.21 square miles, it is Massachusetts’s smallest city. Methadone clinics in Massachusetts are certified by SAMHSA ( the Substance Abuse and Mental Health Services Administration) and are required to be run by medical professionals who make sure that each patient receives an appropriate dosage. Methadone relieves opioid cravings and withdrawals, while also blocking the intoxicating effects of opioids, so that relapse becomes much less likely. The medication assistance offered by methadone allows patients to fully benefit from counseling and cognitive behavioral therapies designed to guide individuals through the process of creating long-term positive change. Recovering from opioid addiction has a much greater chance of success when it is paired with methadone treatment.
