Abstract
Polydrug use is a very common phenomenon and represents an important public health problem. The definition of the term has varied since its inception, and consequently so have forms of self-report evaluation. The aim of this review is to offer an overview of how the concept has evolved and its forms of evaluation through self-reporting. A search of the term polydrug was conducted on the PubMed portal up to August 2022, with a total of 2076 publications detected containing the word polydrug in their title, abstract or keywords. This includes publications that represent an advance in the definition and assessment of this construct through self-reports, which may be useful for researchers carrying out future studies in the field. The importance of distinguishing between concurrent and simultaneous polydrug use and the need to employ comparable measures in parameters for the frequency, magnitude and combination of psychoactive substances involved in polydrug use are two of the main recommendations emerging from this review.

Does a mindfulness-augmented version of the German Strengthening Families Program reduce substance use in adolescents? Study protocol for a randomized controlled trial. Trials 2020; 21:114.

Abstract
BACKGROUND Mindfulness training (MT) for parents of adolescents has been shown to improve mental health and stress-related outcomes in individuals and their families. Studies of MT among young people are mainly delivered in educational or clinical settings, and there is a need for controlled studies on both parent-directed and adolescent-directed approaches. It is unclear whether MT has preventive effects for substance use outcomes. The primary objective of this trial is to evaluate the effectiveness of family-based MT targeting both adolescents and their parents to prevent adolescent substance use and enhance neurobehavioral self-regulation skills that play a major role in addiction development and mental health. METHODS/DESIGN The trial design is a superiority, two-arm, randomized controlled trial in which families will participate either in the full curriculum of the evidence-based Strengthening Families Program 10-14 (SFP 10-14, German adaptation) or in a mindfulness-enhanced version of this program (SFP-Mind). Both seven-session interventions are highly structured and will each be delivered over a period of approximately 7 weeks. The experimental intervention SFP-Mind is a modified version of the SFP 10-14 in which some elements were eliminated or changed to enable the inclusion of additional parent-directed and adolescent-directed mindfulness components. The primary outcome is adolescent self-reported alcohol use based on an alcohol initiation index at 18-month follow-up. Dispositional mindfulness, impulsivity, and emotion regulation will be included as secondary outcomes and potential mechanisms of action. The study will recruit and randomize 216 adolescents, aged 10-14 years, and their parents who will be followed up for 18 months. DISCUSSION This trial aims to evaluate the effectiveness of SFP-Mind for family-based prevention of substance use and promoting mental health in adolescence.

Abstract
PURPOSE To examine cigarette use and the tobacco-related environment among adolescents living in metropolitan and nonmetropolitan areas. METHODS Data from adolescents ages 14-17 that completed the 2012 Florida Youth Tobacco Survey were analyzed (n = 40,746). This includes a representative sample of middle and high school students throughout the state. RESULTS Nonmetropolitan adolescents were more likely than metropolitan adolescents to report lifetime smoking, past 30-day smoking, daily smoking, initiating smoking at younger ages, having smoked a greater number of cigarettes in their lifetime and in the past 30 days, friend acceptance of adult smoking, a parent offering them a cigarette, living with a smoker, and that smoking was allowed in their home. Nonmetropolitan adolescents were also more likely to have seen tobacco ads the last time they visited convenience marts, gas stations, grocery stores, and big box stores, and flavored tobacco products or ads for them. These differences persisted after controlling for demographics. CONCLUSIONS The present results suggest vast differences in smoking behavior among nonmetropolitan and metropolitan adolescents and that targeting social and environmental factors may be beneficial for reducing tobacco disparities among nonmetropolitan adolescents.

Abstract
Aims New trends in drug consumption reveal increasing polydrug use. Epidemiological indicators in the current use are based on the prevalence and the associated potential harm of a single “main” substance. We propose new indicators to evaluate frequency and potential harm of polydrug use. The indicators are used to compare drug use among countries based on survey data on adolescents' substance use in 38 European countries. Methods The approach is based on analysis of the frequency of use in the various population samples: lifetime use, twelve months use or last thirty days, depending on available data, and on the risk of harm for the substances used. Two indicators are provided: the frequency of use score (FUS) by summing the frequency of use of each substance, and the polydrug use score (PDS) that weight all the substances used by their risk. Results The indicators FUS and PDS were calculated and the distribution functions were used to characterise substance use across ESPAD countries. The analysis shows important differences in poly-substance use severity among countries presenting similar prevention policies. Conclusions Systematic analysis of substance use and the related risk are of paramount interest. The proposed indicators are designed to better monitor and understand consequences of polydrug use and to measure the resulting risk at country or population level. The indicators may also be used to assess the effects of policy interventions.

Abstract
As part of an ongoing investigation, data were collected on behaviors and attitudes about substance abuse and general knowledge about substances for high school students ( N = 1,103) during the 2002–2003 and 2003–2004 academic years. In preliminary analyses no meaningful sex differences were found for type or frequency of use, attitudes about substance use, or knowledge about substances. Lack of meaningful sex differences were evident even when comparisons by sex group were made within this ethnic minority population as well as within school Grades 10, 11, and 12. It is suggested that being a boy or a girl may have little to do with the American middle-class adolescents' choice to use substances. Findings should be understood to suggest possible cohort effects.

Abstract
We report long-term effects of the PROSPER delivery system for universal evidence-based preventive interventions on adolescent conduct problem behaviors (CPBs). A cluster randomized trial included 28 school districts assigned to PROSPER or a control condition. Community-based teams in PROSPER condition school districts selected evidence-based interventions-a family-focused intervention in sixth grade and a school-based intervention the next year; follow-up assessments were conducted through 12th grade. CPBs were measured with 12 self-report items derived from the National Youth Survey. Intervention-control differences were tested via a multi-level Zero-Inflated Poisson (ZIP) model. Differences were significant from 9th through 12th grades; Relative Reduction Rates were between 10.1% and 14.5%. The intervention group was delayed in reaching a 10th grade reference level of CPBs by 10.7 months. Moderation analyses indicated stronger effects for early substance initiators. Findings suggest that the PROSPER delivery system has the potential to reduce CPBs in general populations.

Abstract
OBJECTIVE For many substances, more frequent and problematic use occurs in young adulthood; these types of use are predicted by the timing of initiation during adolescence. We replicated and extended an earlier study examining whether delayed substance initiation during adolescence, resulting from universal preventive interventions implemented in middle school, reduces problematic use in young adulthood. METHOD Participants were middle school students from 36 Iowa schools randomly assigned to the Strengthening Families Program: For Parents and Youth 10-14 (Molgaard, Spoth, & Redmond, 2000) plus Life Skills Training (LST; Botvin, 1995, 2000), LST-only, or a control condition. Self-report questionnaires were collected at 11 time points, including 4 during young adulthood. The intercept (average level) and rate of change (slope) in young adult frequency measures (drunkenness, alcohol-related problems, cigarettes, and illicit drugs) across ages 19-22 were modeled as outcomes influenced by growth factors describing substance initiation during adolescence. Analyses entailed testing a 2-step hierarchical latent growth curve model; models included the effects of baseline risk, intervention condition assignment, and their interaction. RESULTS Analyses showed significant indirect intervention effects on the average levels of all young adult outcomes, through effects on adolescent substance initiation growth factors, along with Intervention × Risk interaction effects favoring the higher risk subsample. Additional direct effects on young adult use were observed in some cases. Relative reduction rates were larger for the higher risk subsample at age 22, ranging from 5.8% to 36.4% on outcomes showing significant intervention effects. CONCLUSIONS Universal preventive interventions implemented during early adolescence have the potential to decrease the rates of substance use and associated problems into young adulthood.

Abstract
Considering the prevalence and consequences of health-risking sexual behaviors (HRSBs) and STDs among young adults, their prevention is a public health priority. Emerging etiological and prevention outcome literatures suggested study of the long-term effects of universal family-focused interventions on young adult HRSBs and STDs. Although earlier studies have demonstrated intervention impact on adolescent substance misuse, no study has examined universal family-focused intervention effects on young adult HRSBs and STDs via reductions in adolescent misuse. Sixth grade students and their families enrolled in 33 rural Midwestern schools were randomly assigned to experimental conditions. Self-report questionnaires provided data at pretest (Ns = 238, 221, and 208 for the Iowa Strengthening Families Program [ISFP], Preparing for the Drug Free Years [PDFY], and control groups, respectively), with seven data points through young adulthood (age 21). In latent growth modeling, three young adult HRSB measures (number of sexual partners, condom use, substance use with sex) and lifetime STDs were specified as distal outcomes mediated by adolescent substance initiation growth factors (average level and rate of change). Results showed that the models fit the data and, except for condom use, there were significant indirect effects, with a higher frequency of significant findings for ISFP. The model additions of direct intervention effects on young adult outcomes generally were not supported, consistent with a model positing that long-term intervention effects on young adult HRSBs and STDs outcomes are indirect. As an indication of the practical significance of long-term effects, analyses revealed relative reduction rates ranging from 6% to 46% for significant outcomes.

Abstract
The aim of this study was to examine sexual risk behavior among adolescents in the United States classified as early initiators of sexual intercourse. Secondary analyses were carried out with data from the 2007 Youth Risk Behavior Survey (n=14,041). Only adolescents 16-18 years old who reported being sexually experienced were selected for analyses (n=5315, 48% female). Of sexually experienced adolescents, 11% were classified as early initiators of sexual intercourse. Based on prior research it was expected that early initiators of sexual intercourse would demonstrate increased sexual risk behavior when compared to adolescents who initiated sexual intercourse at later ages and that there would be ethnic and gender differences in risk behavior. Early initiators were significantly more likely to report multiple sex partners in their lifetime and were more likely to drink or use drugs before the last time they had sex. Overall, the findings did not demonstrate differences in sexual risk based on gender and ethnicity.

Abstract
Project SUCCESS is a selective and indicated substance use prevention program that targets high risk students in secondary school settings. We evaluated the effects of Project SUCCESS on adolescents' substance use immediately following program implementation, and again one year later. Two successive cohorts of alternative high schools were randomly assigned to an intervention or control group, yielding seven schools per condition. Main outcomes included 30-day use of alcohol, marijuana, and illegal drugs excluding marijuana, and drinking to intoxication. We conducted exploratory analyses on 30-day cigarette use. Using Hierarchical Linear Modeling, we found that students in the control schools reported significantly less use of illegal drugs excluding marijuana than those in the intervention group at the first posttest; however, this effect did not persist one year later. There were no other outcome effects of even a marginal nature. While results of this study do not provide evidence of Project SUCCESS' effectiveness, students' program exposure was low. It is possible that Project SUCCESS would perform better in schools with higher and more regular rates of attendance.

Abstract
Patterns of substance use are examined in a sample of over 1,200 youth in a non-metropolitan region of New England. Self-reported history and frequency of alcohol, tobacco, marijuana, inhalants, pain medications, and other hard drug use was assessed for 9th and 10th grade students. Latent class analyses identified four patterns of substance use: non-users (22%), alcohol experimenters (38%), occasional polysubstance users (29%), and frequent polysubstance users (10%). Contextual risk and protective factors in the individual, family, peer, and community domains predicted substance use patterns. Youth report of peer substance use had the largest effects on substance use class membership. Other individual characteristics (e.g., gender, antisocial behavior, academic performance, perceived harm from use), family characteristics (e.g., parental drinking, parental disapproval of youth use), and community characteristics (e.g., availability of substances) demonstrated consistent effects on substance use classes. Implications for prevention are discussed from a social-ecological perspective.

Abstract
In this article, the authors examine whether delayed substance initiation during adolescence, achieved through universal family-focused interventions conducted in middle school, can reduce problematic substance use during young adulthood. Sixth-grade students enrolled in 33 rural midwestern schools and their families were randomly assigned to 3 experimental conditions. Self-report questionnaires provided data at 7 time points for the Iowa Strengthening Families Program (ISFP), Preparing for the Drug Free Years (PDFY), and control groups through young adulthood. Five young adult substance frequency measures (drunkenness, alcohol-related problems, cigarettes, illicit drugs, and polysubstance use) were modeled as distal outcomes affected by the average level and rate of increase in substance initiation across the adolescent years in latent growth curve analyses. Results show that the models fit the data and that they were robust across outcomes and interventions, with more robust effects found for ISFP. The addition of direct intervention effects on young adult outcomes was not supported, suggesting long-term effects were primarily indirect. Relative reduction rates were calculated to quantify intervention-control differences on the estimated proportion of young adults indicating problematic substance use; they ranged from 19% to 31% for ISFP and from 9% to 16% for PDFY.

Abstract
This paper examines the relationship between ethnic identification and substance use for 1,346 Mexican-heritage preadolescents in a National Institute on Drug Abuse-funded study in Phoenix, Arizona (2004-2005). Participants ranged from 9 to 13 years old, 49% reported their gender as male, 33% self-identified as Mexican, and 67% as Mexican American, and 91% of the students reported taking part in the free or reduced-price lunch program. Questionnaire responses were analyzed by fitting regression models. Analyses showed that ethnic identification may play a protective role, with stronger ethnic identification related to more antidrug norms, less positive drug expectations, stronger refusal efficacy, and less intent to use substances. While gender did not significantly moderate the relationships, ethnic identification appears more broadly related to antisubstance-use norms for Mexican-born than U.S.-born participants. This study presents important implications for substance-use prevention research among Mexican heritage preadolescents. Finally, limitations of the study are noted.

Abstract
This article reports adolescent substance use outcomes of universal family and school preventive interventions 5(1/2) years past baseline. Participants were 1677 7th grade students from schools (N=36) randomly assigned to the school-based Life Skills Training plus the Strengthening Families Program: For Parents and Youth 10-14 (LST+SFP 10-14), LST-alone, or a control condition. Self-reports were collected at baseline, 6 months later following the interventions, then yearly through the 12th grade. Measures included initiation-alcohol, cigarette, marijuana, and drunkenness, along with a Substance Initiation Index (SII)-and measures of more serious use-frequency of alcohol, cigarette, and marijuana use, drunkenness frequency, monthly poly-substance use, and advanced poly-substance use. Analyses ruled out differential attrition. For all substance initiation outcomes, one or both intervention groups showed significant, positive point-in-time differences at 12th grade and/or significant growth trajectory outcomes when compared with the control group. Although no main effects for the more serious substance use outcomes were observed, a higher-risk subsample demonstrated significant, positive 12th grade point-in-time and/or growth trajectory outcomes for one or both intervention groups on all measures. The observed pattern of results likely reflects a combination of predispositions of the higher-risk subsample, the timing of the interventions, and baseline differences between experimental conditions favoring the control group.

Abstract
The main objective of this paper is to explore poly-drug use among young adult ecstasy users. This phenomenon of using multiple substances within a specific time period is multi-faceted. In this paper, we focus on the various patterns of poly-drug use and the reasons for combining multiple drugs among ecstasy users. Using a mixed-methods design, we conducted interviews with young adults who used ecstasy and other licit and illicit drugs in the past 90 days. Based on the qualitative analyses, we define three distinct types of poly-drug experiences: separate, synergistic, and indiscriminate use. While separate and synergistic poly-drug use tended to be intentional, indiscriminate poly-drug use often was unintentional. These findings show the importance of recognizing poly-drug use as a common phenomenon. The findings presented here suggest areas for further research aimed at identifying risk and protective behaviors and risk reduction strategies.

Abstract
To examine patterns of mono- versus polydrug abuse, data were obtained from intake records of 69,891 admissions to publicly funded treatment programs in Tennessee between 1998 and 2004. While descriptive statistics were employed to report frequency and patterns of mono- and polydrug abuse by demographic variables and by study years, bivariate logistic regression was applied to assess the probability of being a mono- or polydrug abuser for a number of demographic variables. The researchers found that during the study period 51.3% of admissions reported monodrug abuse and 48.7% reported polydrug abuse. Alcohol, cocaine, and marijuana were the most commonly abused substances, both alone and in combination. Odds ratio favored polydrug abuse for all but one drug category-other drugs. Gender did not affect drug abuse patterns; however, admissions for African Americans and those living in urban areas exhibited higher probabilities of polydrug abuse. Age group also appeared to affect drug abuse patterns, with higher odds of monodrug abuse among minors and adults over 45 years old. The discernable prevalence of polydrug abuse suggests a need for developing effective prevention strategies and treatment plans specific to polydrug abuse.

Abstract
OBJECTIVES We consider gender and ethnic differences in the co-occurrence of adolescent behaviors related to health and well-being. DESIGN Using a nationally representative sample of adolescents in the National Longitudinal Survey of Youth (1997-2000), we examine behavior among students as well as school drop-outs. We use latent class models (LCMs) to identify subpopulations of adolescents with similar patterns of co-occurring behaviors. The generalizability of the findings for African American adolescents in the 1970s is considered using a sample of inner-city youth from the Pathways to Adulthood Survey. RESULTS For all ethnic groups, we find a subpopulation with 'problem behavior' characteristics (in which early sexual initiation, alcohol use, smoking, marijuana use, and truancy are all highly prevalent). This cluster is most common among European American adolescents and among young men. A subpopulation characterized by behaviors often leading to poor social outcomes (e.g. truancy, early sexual initiation and fighting) is most common for African American adolescents, especially young African American men. CONCLUSION Our findings suggest that multi-factorial interventions which address the interrelationships between all of the behaviors are relevant regardless of gender or ethnicity. However, the ethnic and gender differences in the likelihood of specific patterns of interrelationships highlight the importance of considering the ethnic and gender composition of a population when developing future research and interventions.
