PORTLAND, Maine — The American Civil Liberties Union of Maine started making its case in federal court on Monday against the ban on medication-assisted treatment in county jail amid the opioid crisis. Democratic Gov. Janet Mills recently lifted the Maine Department of Corrections’ ban on medication-assisted treatment. The ACLU’s lawsuit filed in September argued that it’s unconstitutional and harmful for Maine jails to prohibit such treatment. Madawaska resident Brenda Smith sued, asking to continue using medication-assisted treatment to keep her opioid use disorder in remission.
