This study assesses the associations of child salivary cotinine, parent-reported smoking, and child tobacco smoke exposure with the number of child healthcare visits and hospital admissions over a 6-month period. This study also assesses the relationships between participant characteristics and child cotinine. ⋯ Routine biochemical screening could identify children who are in need of intensive tobacco smoke exposure reduction interventions.

E-cigarette use increased dramatically among U.S. students during 2017-2019, and school plays an important role in preventing and reducing youth substance use. This study examines the prevalence and correlates of self-reported youth observation of e-cigarette use on school grounds. ⋯ E-cigarette use is common on school grounds, and youth observation of vaping in schools may increase the risk of initiating tobacco use in the future. School vaping policy and education programs are needed to curb youth e-cigarette use.

The advent of direct-acting antiviral agents for treating hepatitis C virus infection has made hepatitis C virus elimination possible. Rural patients with hepatitis C virus infection may be less likely to access direct-acting antiviral agents, but the real-world evidence is scarce on urban-rural disparities in direct-acting antiviral agent utilization. ⋯ This study reveals important gaps in hepatitis C virus treatment and suggests increasing urban-rural disparities in direct-acting antiviral agent utilization. Enhancing direct-acting antiviral agent uptake in rural populations with hepatitis C virus infection will help reduce hepatitis C virus‒related health disparities and reach the national goal of eliminating hepatitis C virus infection.

The trends in e-cigarette prevalence and population count of users according to cigarette smoking histories are unknown. These data are needed to inform public health actions against a rapidly changing U.S. e-cigarette market. ⋯ The continuous increase among younger-adult never smokers suggests a rise in primary nicotine initiation with e-cigarettes. The concomitant increase among near-term quitters of all age groups suggests continuing e-cigarette use among smokers who may have switched from cigarettes previously.

Vaping has become an increasingly common mode of administration for marijuana among youth, but there are limited data on its prevalence. There is a need to better understand youth prevalence of past 30-day marijuana vaping and its predictors. ⋯ Past 30-day marijuana vaping is prevalent among U.S. students, and there are robust associations between use and school- and substance-related risk behaviors. These results suggest that the emergence of vaping products might redefine populations at risk, which should be taken into account by marijuana regulatory policies or prevention programs.
