This report summarizes a national survey of drug use and related attitudes among American secondary school students. All of its data came from an ongoing national research and reporting program entitled, "Monitoring the Future: A Continuing Study of the Lifestyles and Values of Youth." These surveys address two major topics: (1) the prevalence of drug use among American students in 8th, 10th, and 12th grades; and (2) drug use trends by those students. Distinctions were drawn among demographic subgroups, incidence of first use recorded, trends in use at lower grade levels, and intensity of drug use. Also included were key attitudes about illicit drug use--incorporating perceptions of the social environment--as potential explanatory factors. The research focused on frequent drug use rather than analyzing everyone who has ever used drugs. This strategy serves to differentiate levels of seriousness, or extent, of drug involvement. Survey results indicate that the last decade witnessed an appreciable decrease in the use of numerous illicit drugs among seniors. However, eighth-graders exhibited a significant increase in some drug use, such as marijuana, cocaine, and LSD. This latter evidence may indicate that younger cohorts have less opportunity to learn though informal means about the dangers of drugs. Two appendixes present the prevalence and trend estimates adjusted for absentees and dropouts, and definitions of background and demographic subgroups. (RJM)

Significant changes have taken place in the policy landscape surrounding cannabis legalization, production, and use. During the past 20 years, 25 states and the District of Columbia have legalized cannabis and/or cannabidiol (a component of cannabis) for medical conditions or retail sales at the state level and 4 states have legalized both the medical and recreational use of cannabis. These landmark changes in policy have impacted cannabis use patterns and perceived levels of risk. However, despite this changing landscape, evidence regarding the short- and long-term health effects of cannabis use remains elusive. While a myriad of studies have examined cannabis use in all its various forms, often these research conclusions are not appropriately synthesized, translated for, or communicated to policy makers, health care providers, state health officials, or other stakeholders who have been charged with influencing and enacting policies, procedures, and laws related to cannabis use. Unlike other controlled substances such as alcohol or tobacco, no accepted standards for safe use or appropriate dose are available to help guide individuals as they make choices regarding the issues of if, when, where, and how to use cannabis safely and, in regard to therapeutic uses, effectively. Shifting public sentiment, conflicting and impeded scientific research, and legislative battles have fueled the debate about what, if any, harms or benefits can be attributed to the use of cannabis or its derivatives, and this lack of aggregated knowledge has broad public health implications. The Health Effects of Cannabis and Cannabinoids provides a comprehensive review of scientific evidence related to the health effects and potential therapeutic benefits of cannabis. This report provides a research agendaâ€"outlining gaps in current knowledge and opportunities for providing additional insight into these issuesâ€"that summarizes and prioritizes pressing research needs.

Bringing together leading experts, this book demonstrates the unique value of brief motivational interventions for addressing adolescent alcohol and other substance use in a range of clinical contexts. It presents cutting-edge knowledge on the etiology and developmental context of adolescent addictive behaviors and reviews exemplary treatment approaches. Effective strategies are described for intervening with diverse populations, such as college students, youth in the justice system and in foster care, those with co-occurring substance abuse and psychiatric problems, LGBT youth, and Latino and American Indian adolescents. This book replaces the editors' influential earlier work, Adolescents, Alcohol, and Substance Abuse, with an expanded focus on practical applications. Most of the chapters are completely new.

Does success in school protect teenagers from drug use? Does drug use impair scholastic success? This book tackles a key issue in adolescent development and health - the education-drug use connection. The authors examine the links and likely causal connections between educational experiences, delinquent behavior, and adolescent use of tobacco, alco
