Description
Marijuana is currently the mostly widely used illicit drug in the U.S., and has been for multiple decades (Johnston et. al., 2016). Despite a growing belief that marijuana use is not harmful, over 4 million Americans have met criteria for marijuana use disorders in the past year alone (CBHSQ, 2015). According to marijuana trajectory studies, about a third of marijuana users will end up quitting later in life, but some \u2014 such as those who meet criteria for dependence \u2014 have a much greater difficultly quitting. Therefore, by looking at marijuana users who were successful in quitting, and comparing them to ongoing adult marijuana users, factors that may assist in helping an individual quit \u2014 such as certain motivations for quitting \u2014 may be identified. To study these issues, data was collected from 507 participants from the Pittsburgh Youth Study. It was found that adolescents who used marijuana weekly for at least one year were likely to be ongoing marijuana users in adulthood and that adolescents who had a warm relationship with their primary caretaker were likely to have quit marijuana by adulthood. It was also found that Black participants were more likely to have legal, monetary, and religious reasons for quitting than were White participants. Furthermore, participants who used regularly in adolescence were likely to list legal reasons, as well as a concern that marijuana use was needed to feel normal. Finally, it was found that not a single motivation for quitting marijuana was associated with a shorter period of abstinence. The implications of these findings for motivations to quit marijuana are the focus of the discussion.

Description
This study explores the relationship between the use of different substances and different kinds of stress from before and after the COVID-19 pandemic. The substances looked at were: alcohol, marijuana, caffeine, vape or nicotine use, and the use of prescription pills that were not prescribed to the user. The different kinds of stress that were examined were: academic, social, financial, and stress caused by the outbreak of COVID-19.

Description
The primary goal of this study was to investigate whether youth from an affluent community showed elevated rates of substance use and associated problems in young adulthood relative to national norms. The secondary goal was to determine if parents’ “containment,” or stringent disciplinary action, of adolescent substance use as measured in Grade 12 could help predict substance use in senior year of college, over and above other parenting factors. The final goal was to assess trends of substance use over time for stability based on categories of participants’ overall levels of use in Grade 12, (low, medium, high). Results indicated that substance use remained elevated into young adulthood, relative to national norms, consistent with extant research involving upper middle class youth. In regression analyses, high parents’ containment was associated with low substance use in senior year of college; however, the inclusion of Grade12 use as a covariate reduced this association with containment such that it was no longer statistically significant. Such results suggest a mediated effect, with Grade 12 substance use mediating the effects of Grade 12 Containment on college senior year substance use. Finally, upper middle class youth were found to remain in their relative substance use group (low, medium, high) as determined at Grade 12 through all four years of college. Taken together, these results emphasized the importance of high school substance use behaviors as a notable risk factor for problematic substance use over time.

Description
Adolescent substance use is a complex and significant public health concern that has received considerable attention among researchers and practitioners (Gray & Squeglia, 2018). The purpose of this dissertation was to examine factors associated with substance use intervention effects and to develop subgroups of risk factors for Mexican adolescents. This dissertation utilizes secondary data from a randomized controlled trial of the school-based substance use universal prevention program, keepin’ it REAL (kiR). The dissertation included two studies. Study 1: This study tested a model on the efficacy of the school-based substance use universal prevention program, keepin’ it REAL, among a sample of Mexican adolescents (N = 3,742, 11-17 years old). Study 1 analysis included Structural Equation Modeling and results demonstrated that participation in kiR positively predicted alcohol resistance strategies and those alcohol resistance strategies were negatively and significantly associated with alcohol use. Further, depressive symptomology was a moderator of intervention effects as the effects of kiR on resistance strategies increased as the level of depressive symptomology increased. Study 2: this study explored subgroups (classes) of Mexican adolescents (N = 5,520, 11-14 years old) based on their experiences with violence (witnessing, victimization, and perpetration), depressive symptomology, and substance use (alcohol, tobacco, and marijuana). Using Latent Class Analysis (LCA) four empirically, well-differentiated classes emerged representing adolescents various risk typologies (Moderate Risk-Violence at 55% of the sample, Low Risk at 35%, High Risk at ~8%; and Moderate Risk-Substance Use at ~2%) Implications for research and practice are discussed across both studies.

Description
Despite the established co-prevalence of substance use (SU) and disordered eating (DE), few longitudinal studies have sought to examine their shared development. Findings have been inconsistent within the extant literature. This may be attributable in part to several methodological aspects, including overlooking distinct psychopharmacological properties of common substances of abuse, examining only between-person relations, and failing to account for shared risk factors. The current study sought to address these gaps by applying latent curve models with structured residuals (LCM-SR) to a preexisting, national sample of adolescent girls followed into adulthood, Add Health. In Aim 1, between-person effects examined the simultaneous development of alcohol, tobacco, and marijuana use and DE behaviors in substance-specific models. In Aim 2, bivariate latent curve models were expanded to account for within-person effects (LCM-SR) in order to examine the potentially bidirectional, prospective relationship between use of a specific substance and DE. Lastly, models accounted for shared developmental risk factors. Findings of the current study demonstrate preliminary evidence of substance-specific effects with DE emerging in adolescence. Across model-building steps, DE engagement in early adolescence was significantly associated with growth in tobacco use and marginally associated with marijuana use. Appetitive side-effects of both substances may link use with DE behaviors and enhance instrumental use for weight control. Significant associations did not emerge between alcohol and DE, and results of the conditional model indicate this co-occurrence is best explained by third variable mechanisms. Implications for prevention are discussed.
