The Massachusetts Alcohol and Substance Abuse Center at Plymouth is a truly unique Department of Correction facility. The facility houses two (2) very distinct populations: criminally sentenced, minimum-security, male inmates and civilly committed males participating in an up to 90-day detoxification program. Individuals participating in the program are committed to the facility under MGL 123, Section 35.


Civil Commitment Population

The Massachusetts Alcohol and Substance Abuse Center's mission is to promote public safety by providing a safe, secure and structure treatment environment for court ordered civil commitments. This is accomplished through medically monitored detoxification services, substance abuse treatment and education including the tools to affect positive change and plans for aftercare in order to promote a healthier and more meaningful lifestyle upon reentry to the community.

Minimum-Security Inmate Population

Provide public safety through safe and humane care and custody practices. Promote an atmosphere of increased responsibility and accountability for the offender providing the basis for positive re-integration into society. Create an environment of mutual respect, fostering positive interactions between offenders, staff, and the public.  A small contingent of approximately 24 minimum security inmates will be providing kitchen work and other tasks around the facility as assigned.



Civil Commitment Population

The program services, provided by MPCH staff, include a comprehensive, multi-phase progression of classes in Relapse Prevention Training in conjunction with case management services, twelve-step programming, assistance in aftercare planning, and individual discharge planning for community-based treatment.

The principle component of treatment addresses substance dependence as an accumulation of cognitive, behavioral, and physiological symptoms. These symptoms are manifested by the individual's persistent use (of the substance) despite recurrent negative substance-related consequences. Further, continued use increases the individual's potential for increased tolerance, withdrawal and compulsive drug/alcohol use. At this time, medical detoxification is required to safety treat the physical symptoms of alcohol and drug withdrawal. Once the individual has withdrawn from alcohol and/or drugs, further treatment is required to address the cognitive and behavioral symptoms of the disease and assess for potential mental health issues.

The correctional facility has greatly changed since it was constructed in 1952 as Restoration Camp #1 at the Myles Standish State Forest. It operated as a prison camp into the 1950s when it became MCI-Plymouth. By 1967, work programs were established in the correctional system and its role continues to change and offer unique opportunities for the inmates. Through the years, many construction projects and renovations have led to the Alcohol and Substance Abuse Center that is meeting the needs of the community today.
