The purpose of this collection is to provide a forum to integrate pre-clinical and clinical investigations regarding the long-term consequences of adolescent exposure to drugs of abuse. Adolescence is characterized by numerous behavioral and biological changes, including substantial neurodevelopment. Behaviorally, adolescents are more likely to engage in risky activities and make impulsive decisions. As such, the majority of substance use begins in adolescence, and an earlier age of onset of use (<15 yr) is strongly associated with the risk for developing a substance use disorder later in life. Furthermore, adolescent drug use may negatively impact ongoing neurological development, which could lead to long-term cognitive and emotional deficits. A large number of clinical studies have investigated both the acute and long-term effects of adolescent drug use on functional outcomes. However, the clinical literature contains many conflicting findings, and is often hampered by the inability to know if functional differences existed prior to drug use. Moreover, in human populations it is often very difficult to control for the numerous types of drugs, doses, and combinations used, not to mention the many other environmental factors that may influence adult behavior. Therefore, an increase in the number of carefully controlled studies using relevant animal models has the potential to clarify which adolescent experiences, particularly what drugs used when, have long-term negative consequences. Despite the advantages of animal model systems in clarifying these issues, the majority of pre-clinical addiction research over the past 50+ years has been conducted in adult animals. Moreover, few addiction-related studies have investigated the long-term neurocognitive consequences of drug exposure at any age. In the past 10 years of so, however, the field of adolescent drug abuse research has burgeoned. To date, the majority of this research has focused on adolescent alcohol exposure using a variety of animal models. The results have given the field important insight into why adolescents are more likely to drink alcohol to excess relative to adults, and the danger of adolescent alcohol use (e.g., in leading to a persistence of excessive drinking in adulthood). More recently, research regarding the effects of adolescent exposure to other drugs of abuse, including nicotine, cocaine, and cannabinoids has expanded. Therefore, we are at unique point in time, when emerging results from carefully controlled pre-clinical studies can inform the sometimes confusing clinical literature. In addition, we expect an influx of prospective clinical studies in response to a cross-institute initiative at NIH, known as the ABCD grant. Several institutes are enrolling children prior to adolescence (and the initiation of drug use), in order to control for pre-existing neurobiological and neurobehavioral differences and to monitor the age of initiation and amount of drug used more carefully than is possible using retrospective designs.

Adolescent substance abuse is the nation's #1 public health problem. It originates out of a developmental era where experimentation with the world is increasingly taking place, and where major changes in physical self and social relationships are taking place. These changes cannot be understood by any one discipline nor can they be described by focusing only on the behavioral and social problems of this age period, the characteristics of normal development, or the pharmacology and addictive potential of specific drugs. They require knowledge of the brain's systems of reward and control, genetics, psychopharmacology, personality, child development, psychopathology, family dynamics, peer group relationships, culture, social policy, and more. Drawing on the expertise of the leading researchers in this field, this Handbook provides the most comprehensive summarization of current knowledge about adolescent substance abuse. The Handbook is organized into eight sections covering the literature on the developmental context of this life period, the epidemiology of adolescent use and abuse, similarities and differences in use, addictive potential, and consequences of use for different drugs; etiology and course as characterized at different levels of mechanistic analysis ranging from the genetic and neural to the behavioural and social. Two sections cover the clinical ramifications of abuse, and prevention and intervention strategies to most effectively deal with these problems. The Handbook's last section addresses the role of social policy in framing the problem, in addressing it, and explores its potential role in alleviating it.

The papers in these proceedings of the September 2003 conference examine this key period in life and its associated behavioral and emotional problems. General paper topics include risk taking and novelty seeking, brain and cognitive development, the interrelationships between hormones and behavior, nicotine and alcohol use, sleep and arousal, and the regulation of behavior and emotion. The volume includes short papers on human and animal studies. Papers include their own references. Annotation ©2004 Book News, Inc., Portland, OR (booknews.com).

The period of transition from childhood to adulthood is called adolescence. It is accompanied by various psychological and physical changes in an individual. In terms of behavior, the probability of adolescents making rash and impulsive decisions is high. Therefore, it has been noted that drug use begins during adolescence and is connected to later problems with drug addiction related disorders. The usage of drugs during this sensitive period can have a negative effect on the neurological development which takes place during this period. This in turn can lead to long-term cognitive and emotional deficits. Some of the substances commonly abused by adolescents are cannabis, alcohol and tobacco. This book unfolds the innovative aspects of research on adolescent drug use which will be crucial for the progress of this field in the future. Also included herein is a detailed explanation of the recent patterns and consequences which have been observed. The extensive content of this book provides the readers with a thorough understanding of the subject.

When developmental psychologists set forth the theory that the roots of adult psychopathology could be traced to childhood experience and behavior, the idea quickly took hold. Subsequently, as significant research in this area advanced during the past decade, more sophisticated theory, more accurate research methodologies, and improved replication of empirical findings have been the result. The Third Edition of the Handbook of Developmental Psychopathology incorporates these research advances throughout its comprehensive, up-to-date examination of this diverse and maturing field. Integrative state-of-the-art models document the complex interplay of risk and protective factors and other variables contributing to normal and pathological development. New and updated chapters describe current refinements in assessment methods and offer the latest research findings from neuroscience. In addition, the Third Edition provides readers with a detailed review across the spectrum of salient topics, from the effects of early deprivation to the impact of puberty. As the field continues to shift from traditional symptom-based concepts of pathology to a contemporary, dynamic paradigm, the Third Edition addresses such key topics as: Early Childhood disorders, including failure to thrive and attachment disorders. Aggression, ADHD, and other disruptive conditions. Developmental models of depression, anxiety, self-injury/suicide, and OCD. The autism spectrum and other chronic developmental disorders. Child maltreatment and trauma disorders. The Third Edition of the Handbook of Developmental Psychopathology is a discipline-defining, forward-looking resource for researchers, clinicians, scientist-practitioners, and graduate students in such fields as developmental psychology, psychiatry, social work, child and school psychology, educational psychology, and pediatrics.“p>

All across the United States, individuals, families, communities, and health care systems are struggling to cope with substance use, misuse, and substance use disorders. Substance misuse and substance use disorders have devastating effects, disrupt the future plans of too many young people, and all too often, end lives prematurely and tragically. Substance misuse is a major public health challenge and a priority for our nation to address. The effects of substance use are cumulative and costly for our society, placing burdens on workplaces, the health care system, families, states, and communities. The Report discusses opportunities to bring substance use disorder treatment and mainstream health care systems into alignment so that they can address a person's overall health, rather than a substance misuse or a physical health condition alone or in isolation. It also provides suggestions and recommendations for action that everyone-individuals, families, community leaders, law enforcement, health care professionals, policymakers, and researchers-can take to prevent substance misuse and reduce its consequences.
