Purpose: Adverse childhood experiences (ACEs) are common in Puerto Rican youths. Few large longitudinal studies of Latine youth examined what predicts co-use of alcohol and cannabis in late adolescence and young adulthood. We investigated the prospective association between ACEs with alcohol/cannabis co-use in Puerto Rican youth.
Methods: Participants from a longitudinal study of Puerto Rican youth (n = 2,004) were included. Using multinomial logistic regressions to test associations between prospectively reported ACEs (11 types, reported by parents and/or children, categorized as 0-1, 2-3, and 4+ ACEs) with young adult alcohol/cannabis use patterns in the past month (i.e., no lifetime use, low-risk [no binge drinking and cannabis use < 10], binge-drinking only, regular cannabis use only, and alcohol/cannabis co-use). Models were adjusted for sociodemographic variables.
Results: In this sample, 27.8% reported 4+ ACEs, 28.6% endorsed binge drinking, 4.9% regular cannabis use, and 5.5% alcohol/cannabis co-use. Compared to individuals with no lifetime use, those reporting 4+ (vs. 0-1) ACEs had greater odds of low-risk use (adjusted odds ratio [aOR] 1.60, 95% confidence interval [CI] = 1.04-2.45), regular cannabis use (aOR 3.13 95% CI = 1.44-6.77), and alcohol/cannabis co-use (aOR 3.57, 95% CI = 1.89-6.75). In relation to low-risk use, reporting 4+ ACEs (vs. 0-1) was associated with 1.96 odds (95% CI = 1.01-3.78) of regular cannabis use and 2.24 odds (95% CI = 1.29-3.89) of alcohol/cannabis co-use.
Discussion: Exposure to 4+ ACEs was associated with the occurrence of adolescent/young adulthood regular cannabis use and alcohol/cannabis co-use. Importantly, ACEs exposure differentiated young adults who were co-using compared to those engaged in low-risk use. Preventing ACE or interventions for Puerto Rican youth experiencing 4+ ACEs may mitigate negative consequences associated with alcohol/cannabis co-use.

: Despite associations between sleep problems and substance use, many adults use alcohol and cannabis as sleep aids. However, little is known about the potential reciprocal relations among problems with sleep, alcohol use, cannabis use, and their co-use over time. : This is a secondary analysis from a nationally representative adults (N[unweighted] = 26,072) from the first four waves (2013-2018) of the Population Assessment of Tobacco and Health (PATH) Study.

The purpose of the present study was to examine (1) differences in descriptive and injunctive norms for alcohol, cannabis, and co-use, (2) whether descriptive and injunctive norms for alcohol, cannabis, and co-use were associated with co-use frequency, and (3) whether co-use descriptive and injunctive norms were associated with co-use consequences. Participants were 209 college students who were required to have engaged in only alcohol, only cannabis, and co-use in the past year. Participants completed an online survey about their substance use.

Introduction: Young adulthood constitutes a period of substance use risk and many young adults engage in use of more than one substance. While existing work has examined young adult co-use of substances at the day-level, there has not been a comprehensive investigation of day-level substance use that considers mode and intensity of use in a national sample of U.S.

Background: Previous work has linked substance use to intimate partner violence (IPV) perpetration, but the extent to which patterns of substance use influence patterns of IPV perpetration is unclear.

Introduction: The salience network may be linked to addiction. Evidence suggests less salience network resting state functional connectivity (rsFC) from heavy alcohol use, but higher rsFC within and between brain networks from regular cannabis use. Given the rise in alcohol-cannabis co-use, the present study sought to elucidate rsFC between regions within the salience network and regions across the whole brain in individuals who use no drugs regularly, those who use alcohol only heavily, and those who co-use alcohol-cannabis.
