In the late 1990s, in an effort to dispute the link between secondhand smoke and lung cancer, Philip Morris initiated a campaign to legislate “sound science.” The campaign involved enacting data access and data quality laws to obtain previously confidential research data in order to reanalyze it based on industry-generated data quality standards. Philip Morris worked with other corporate interests to form coalitions and workgroups, develop a “data integrity” outreach program, sponsor symposia on “research integrity,” and draft language for the new acts. The tobacco industry played a role in establishing laws that increase corporate influence on public health and regulatory policy decisions.
