Purpose: Examine tobacco use on college campuses by assessing: (1) types of tobacco products used, (2) where they are most commonly used, and (3) the sociodemographic characteristics of students most likely to use on campus. Method: Participants were a convenience sample of 3,575 18- to 25-year-old enrolled in 14 Texas colleges during Spring 2021…

Objective: This article tests the substance use behaviors of college students before and during COVID-19 pandemic. Methods: In-depth assessment and nightly survey data was used from a longitudinal study (n = 675) which examined student substance use during the 2019-2020 academic year, both before and during the onset of the COVID-19 pandemic.…

Adolescent substance misuse is a persistent concern in the USA and student substance possession on campus presents as an increasing challenge for administrators. This study seeks to understand how students are differentially disciplined for substance possession based on substance type and student race/ethnicity in US schools. Based a national…

In the summer of 2020, SARS-CoV-2 infection rates among the U.S. population aged 20-39 years exceeded other age groups, with the largest increases occurring in the southern US. As many colleges reopened for in-person instruction in August and September, these trends continued among campuses across the country. Our study aimed to identify risk…

This study investigated the extent to which adolescent social network positions are associated with the risk of lifetime daily smoking and nicotine dependence (ND), and whether these associations differ by gender. Using data from the National Longitudinal Study of Adolescent to Adult Health (N = 6,267), this study estimated multinomial logistic…

Polysubstance use is associated with myriad short- and long-term health outcomes. Although prior research has documented differences in polysubstance use between lesbian, gay, bisexual, transgender, queer/questioning, and other sexual and gender minoritized (LGBTQ +) youth and their heterosexual/cisgender counterparts, as well as between subgroups…

Objective: The purpose of this study was to examine patterns of concurrent cannabis and other substance use and their differential associations with cannabis-related problems and academic outcomes in college students.

On March 7, 1962 the Royal College of Physicians published a report entitled "Smoking and Health" that made the causal link between smoking and lung cancer clear and explicit. Using a historical data set that contains information on smoking from 1958 to 1965, I find a decrease in smoking for those with more schooling after the report's…

A later school start time policy has been recommended as a solution to adolescents' sleep deprivation. We estimated the impacts of later school start times on adolescents' sleep and substance use by leveraging a quasi-experiment in which school start time was delayed in some regions in South Korea. A later school start time policy was implemented…

We examined the prevalence and correlates of anticipated responses to hypothetical cigar price increases. Data are from a 2021 representative sample of U.S. adults who reported past-30-day cigar use (n = 454; mean age = 39.8 years). Weighted multivariable logistic regressions assessed the correlates of behavior change responses. If cigar price…

Current use of vaping products has increased in recent years among youth in the United States. We conducted cross-sectional surveys of vaping product users aged 15-17 in New York in 2017 and 2019 to assess vaping frequency, reported nicotine content of vaping products used, risk perceptions of vaping and openness to vaping cannabis (2019 survey…

Completely switching from cigarette smoking to electronic nicotine delivery systems (ENDS) reduces exposure to toxic substances. Yet, many smokers believe that ENDS are at least as harmful as smoking, making them less likely to switch from cigarettes to ENDS. Effectively communicating reduced-exposure information is critical, but such messages…

Background: Health policies are key social determinants of health, but may cause inequalities if their implementation does not match local needs and if resources are misallocated. This study tests the inverse prevention law on school tobacco policies, assessing inequity in their implementation and identifying contributing factors. Methods: A…

Objective: Electronic cigarette use represents an important college health concern. This investigation assessed demographic and behavioral correlates associated with actual and perceived e-cigarette use among a national sample of American college students. Methods: Respondents (n = 19,861) comprised college students from over 40 distinct American…

Public health campaigns have the potential to correct vaping misperceptions. However, campaigns highlighting vaping harms to youth may increase misperceptions that vaping is equally/more harmful than smoking. Vaping campaigns have been implemented in the United States and Canada since 2018 and in England since 2017 but with differing focus: youth…
