A Public Health Alerts report today notes that cigarette smoking in US adults dropped from 10.8% in 2023 to 9.9% in 2024, while the use of other tobacco products, such as cigars and e-cigarettes, stayed flat, and 18.8% of US adults—or about 48 million—used at least one tobacco product in 2024. Public Health Alerts, a new collaboration between NEJM Evidence and CIDRAP, fills a gap in reliable data, offering expert-reviewed reports that translate frontline observations into actionable public health evidence. An NEJM Evidence editorial explains the initiative further. (Wappes, 3/10)
