In 2012 Massachusetts passed legislation that expands legalized gambling to include resort-style casinos and a slots parlour. Although gambling through the lottery and other mechanisms was already widespread, the new legislation will significantly alter the Commonwealth’s gambling landscape. The legislation called for the establishment of a Public Health Trust Fund, part of which will be used to prevent harms associated with problem gambling. Connection Lab coordinated the state’s development of a Strategic Plan to Mitigate the Harms of Expanded Gambling in Massachusetts, a blueprint for the establishment of prevention intiatives across the prevention continuum from primary preventon through recovery support.
