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…

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…

Cannabis legalization has rapidly spread throughout the United States and is associated with multiple public health outcomes, including driving under the influence of cannabis (DUIC). To improve understanding of the relationship between legalization and DUIC, we tested two potential mediators of this relationship: perceived safety and perceived…

Despite growing evidence to the contrary, researchers continue to posit causal links between cannabis, crime, psychosis, and violence. These spurious connections are rooted in history and fueled decades of structural limitations that shaped how researchers studied cannabis. Until recently, research in this area was explicitly funded to link…

Objective: This qualitative study explored post-secondary students' perceptions of cannabis use on students' health, academic pursuits, and social lives, and investigated how these issues have been impacted by the legalization of recreational cannabis. Participants: 20 undergraduate students at a small liberal arts university in Atlantic Canada…

Background: High cannabis use rates among American Indian (AI) adolescents necessitate the identification of factors that protect against early cannabis initiation. Methods: Data collected from 279 AI middle school students attending reservation-based schools in 2018 and 2019 were analyzed. Three waves of data, with approximately 6 months between…

Little research has examined mechanisms driving cannabis use disparities among sexual minority (SM; versus heterosexual) young adults (YAs). Participants were US YA women (N = 1345; 24.8% bisexual, 6.1% lesbian) and men (N = 998: 8.9% bisexual, 13.8% gay). Bivariate analyses examined associations between sexual orientation (heterosexual,…

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.,…

Objective: To examine the prevalence and correlates of lifetime cannabis use (i.e., experimental [use 1-5 times] and non-experimental [use [greater than or equal to] 6 times]) in relation to interpersonal trauma (IPT) above and beyond relevant covariates. Participants: A large (n = 9,889) representative sample of college students at an urban…

Few studies have compared knowledge of the specific health risks of cannabis across jurisdictions. This study aimed to examine perceptions of the health risks of cannabis in Canada and US states with and without legal non-medical cannabis. Cross-sectional data were collected from the 2018 and 2019 International Cannabis Policy Study online…

Background: The 2018 legalisation of cannabis in Canada sparked concern and conversation about the potential negative impacts of youth cannabis use. It is clear that young people are already engaging in cannabis use for a variety of reasons; therefore, youth cannabis education is desirable to promote harm reduction and reduce the risk of adverse…

Objective: The current study examined the unique predictive ability of tolerance of specific negative affective states in relation to frequency of past-month cannabis use and coping-oriented cannabis use motives. Participants: 416 undergraduates who reported past 30 day cannabis use (65.1% female; M[subscript age] = 19.46, SD = 2.56). Methods:…

This review analyzed the effectiveness of mandated substance use interventions in reducing future cannabis or other illicit drug use. Findings indicated that early decreases in cannabis and other drug use are commonly reported among students participating in mandated interventions. The longer time elapses post-intervention, the more likely…

Objective: Cannabis policies are rapidly evolving in the US. This study's purpose was to examine relationships between cannabis harm perceptions, substance use, and demographic characteristics on attitudes toward cannabis policies. Participants: Participants were 619 undergraduate students in a Mid-Atlantic state where cannabis use was illegal.…

Research has begun to investigate the reliability of cannabis-intoxicated eyewitnesses; however, no studies have evaluated eyewitness memory among chronic cannabis users after a minimum 24-h abstinence. This study compared cannabis users' (n = 23) and nonusers' (n = 26) eyewitness recall/identification and investigated the relationship between…
