The Tobacco Master Settlement Agreement (MSA) was entered on November 23, 1998, originally between the four largest United States tobacco companies (Philip Morris Inc., R. J. Reynolds, Brown & Williamson and Lorillard – the "original participating manufacturers", referred to as the "Majors") and the attorneys general of 46 states. The states settled their Medicaid lawsuits against the tobacco industry for recovery of their tobacco-related health-care costs.[1]: 25 In exchange, the companies agreed to curtail or cease certain tobacco marketing practices, as well as to pay, in perpetuity, various annual payments to the states to compensate them for some of the medical costs of caring for persons with smoking-related illnesses. The money also funds a new anti-smoking advocacy group, called the Truth Initiative, that is responsible for such campaigns as Truth and maintains a public archive of documents resulting from the cases.
The settlement also dissolved the tobacco industry groups Tobacco Institute, the Center for Indoor Air Research, and the Council for Tobacco Research. In the MSA, the original participating manufacturers (OPM) agreed to pay a minimum of $206 billion over the first 25 years of the agreement.
