Campus protections are given a 100% smoke-free designation if smoking is not allowed on campus anywhere, at any time; 100% tobacco-free designations extend smoke-free protections to include non-combustible products such as smokeless tobacco.Results 823 accredited, degree-granting institutions (16.7%) representing 1816 individual campuses, sites and schools have either 100% smoke-free or 100% tobacco-free protections. An estimated 14.9 million college students (26.9%) and 8.9 million faculty and staff (25.4%) are protected by campus policies and state laws. Only three states and two territories have 100% smoke-free or 100% tobacco-free protections in over half of their institutions; four states and six territories have no known 100% smoke-free or 100% tobacco-free campus protections.Conclusions In 2017, just 16.7% of accredited, degree-granting institutions in the USA had 100% smoke-free or 100% tobacco-free protections. Despite progress, more efforts can ensure that students and staff benefit from comprehensive 100% smoke-free and 100% tobacco-free protections at US colleges and universities.
