Objective: Around 40% of US university students use cannabis, 25% of whom present with cannabis use disorder, which endangers health. We investigated the concurrent contribution of reflective processes, which generate action via conscious deliberation, and non-reflective processes, which prompt behavior automatically, to undergraduates' cannabis…

Objective: To explore the feasibility and utility of a tolerance break (T-Break) guide on young adults' cannabis use. Participants: Young adults aged 18--29 (n = 125) who were current cannabis users. Methods: Participants recruited through posters and listservs at various universities were offered the T-Break Guide--daily activities, advice, and…

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…

Given the prevalence of alcohol and cannabis co-use among college students, prevention for co-use is crucial. We examined hypothetical receptiveness to substance-specific interventions among students who reported co-use. Students who use alcohol and cannabis were more receptive to alcohol interventions than cannabis interventions. Campus…

Objective: To investigate the contexts in which college students use e-cigarettes and marijuana, perceptions about the benefits and harms, and health effects of use. Participants: College student e-cigarette and marijuana ever users (n = 20; 18-21 years old) from the Texas Adolescent Tobacco and Marketing Surveillance System (TATAMS). Methods:…

Objective: This study describes beliefs held by college students about cannabis use and examines the association between three specific cannabis beliefs and likelihood of use. Participants: 3,720 undergraduate students ages 18 to 25 attending ten colleges in one state. Methods: Data were gathered via online survey. Results: The majority (80%) of…

Objectives: To assess electronic nicotine delivery system (ENDS) use and vaping behaviors and attitudes in college students. Methods: A student-faculty partnership administered a cross-sectional survey to undergraduate students (N 1/4 339) in 2019. Results: 49.8% of students reported using ENDS or vaping in the past 30 days. 48.9% of students who…

Objective: Electronic Nicotine Delivery System (ENDS) proprietors strategically placed near college campuses and pervasive marketing on social media platforms, such as Facebook, are critical to the tobacco industry's effort to acquire new young adult users. Understanding the themes used on Facebook to promote ENDS products to college students is…

Marijuana use among U.S. college students is the highest since the mid-1980s. Because knowledge about marijuana and confidence in the knowledge are related to changing marijuana laws and marijuana-related messages ubiquitous in college students' information environment, we examined their relationships with use. The Structural Equation Modeling…

Objectives: This study investigates whether recreational marijuana legislation and perceived social norms (descriptive and injunctive) affect college students' propensity to share pro-marijuana messages. We examine which referent group (close friends, typical student, parents) most influence those norms. Participants: A sample of 343 college…

High-risk sexual behaviors (HRSBs; e.g., having sex without protection against pregnancy or sexually transmitted infections) are a public health problem. HRSBs disproportionally impact college students and are associated with numerous negative outcomes, such as unwanted pregnancies. Alcohol use has been strongly linked to HRSBs in college…

Because studies examining youth drug use often have data with a high proportion of zeros, they often do not meet the assumptions for univariate or linear regression analyses that are typically used. We demonstrate the use of zero-inflated negative binomial regression models to address excessive zeros in drug use frequency on perceptions of…

Objective: The purpose of this study is to examine the attitudes and perceptions of college undergraduates regarding cannabis vaping. Participants: Twenty-one, predominantly male (71.4%; M[subscript age] = 22, SD = 2.09), undergraduate college students who reported vaping cannabis in the past 30 days. Methods: Participants were interviewed to…

Perceptions of medical marijuana (MM) use have changed, particularly around its value for chronic illnesses/related symptoms. Social workers are open to questions from clients about use and efficacy of MM. Aims of this study are to assess knowledge and attitudes about MM among graduate social work students. Of the 230 respondents, 88.7% were…

Objective: This study aimed to qualitatively examine how perceptions of cannabis differ among college students in an effort to better understand the changing landscape of cannabis on college campuses. Participants: Forty-six predominantly male (69.9%; M[subscript age] = 23.15, SD = 4.11) college students attending a border state university (i.e.,…
