Public health touches all aspects of a person's life and their sense of wellness. This relates to a person's physical well-being, such as mental health or oral health, but also to the environments, behaviors and other elements that shape where we live, work and play. Public health law impacts these facets by passing laws or policies that ensure equitable access to quality care, encourage us to practice healthy eating and exercise habits and avoid abusing substances, that prevent injuries and violence, and mitigate or remove dangers or hazards in our surroundings. Public Health Law Research (PHLR) approaches public health law holistically, and has research and evidence available for all the topics listed below. The topic pages offer a glimpse at what we know (evidence), projects we have funded, and LawAtlas maps available to illuminate the current state of the law.
