Massachusetts is using a controversial civil commitment law to provide treatment for those with drug addiction. As the country grapples with the opioid epidemic, Massachusetts is using a state law created in the 1970s to tackle how some residents there are treated for their addiction. It's among several states that use involuntary commitment to force someone into addiction treatment if they have an alcohol or substance abuse problem and pose a risk of serious harm to themselves or others. But it's the only state to provide that treatment in a correctional facility, and critics say that's no place for those battling addiction who haven't been charged with a crime.
