Addiction is a chronic relapsing disorder, which comprises impulsive and compulsive elements. Chronic drug consumption leads to long-term neuroadaptive changes in the brain thus result in an addictive state. However, development of addiction is a complex interaction between genetic, epigenetic and environmental factors. The resulting cellular and molecular changes mediate the transition from controlled drug use to the loss of control over drug-taking and drug-seeking. The human association studies helped us to identify some important genetic factors responsible for the susceptibility to addiction. However, social, environmental circumstances highly influence the development of addiction. Using animal models helps us to examine the underlying neuronal/molecular processes under standardised conditions. The aim of this Research Topic is to summarize our knowledge about the neuroplastic changes, which contribute to the maintenance of drug taking. Data presented in this Research Topic should also provide evidences how acute and long-term neuronal changes during withdrawal result in relapse. How different neuromodulators like endocannabinoids and endogenous opioids contribute to molecular mechanisms that mediate the transition from the controlled, occasional drug consumption to the uncontrolled, escalating drug use and seeking.

NEW YORK TIMES BESTSELLER • From a renowned behavioral neuroscientist and recovering addict, a rare page-turning work of science that draws on personal insights to reveal how drugs work, the dangerous hold they can take on the brain, and the surprising way to combat today's epidemic of addiction. Judith Grisel was a daily drug user and college dropout when she began to consider that her addiction might have a cure, one that she herself could perhaps discover by studying the brain. Now, after twenty-five years as a neuroscientist, she shares what she and other scientists have learned about addiction, enriched by captivating glimpses of her personal journey. In Never Enough, Grisel reveals the unfortunate bottom line of all regular drug use: there is no such thing as a free lunch. All drugs act on the brain in a way that diminishes their enjoyable effects and creates unpleasant ones with repeated use. Yet they have their appeal, and Grisel draws on anecdotes both comic and tragic from her own days of using as she limns the science behind the love of various drugs, from marijuana to alcohol, opiates to psychedelics, speed to spice. With more than one in five people over the age of fourteen addicted, drug abuse has been called the most formidable health problem worldwide, and Grisel delves with compassion into the science of this scourge. She points to what is different about the brains of addicts even before they first pick up a drink or drug, highlights the changes that take place in the brain and behavior as a result of chronic using, and shares the surprising hidden gifts of personality that addiction can expose. She describes what drove her to addiction, what helped her recover, and her belief that a “cure” for addiction will not be found in our individual brains but in the way we interact with our communities. Set apart by its color, candor, and bell-clear writing, Never Enough is a revelatory look at the roles drugs play in all of our lives and offers crucial new insight into how we can solve the epidemic of abuse.

Through the vivid, true stories of five people who journeyed into and out of addiction, a renowned neuroscientist explains why the "disease model" of addiction is wrong and illuminates the path to recovery. The psychiatric establishment and rehab industry in the Western world have branded addiction a brain disease. But in The Biology of Desire, cognitive neuroscientist and former addict Marc Lewis makes a convincing case that addiction is not a disease, and shows why the disease model has become an obstacle to healing. Lewis reveals addiction as an unintended consequence of the brain doing what it's supposed to do-seek pleasure and relief-in a world that's not cooperating. As a result, most treatment based on the disease model fails. Lewis shows how treatment can be retooled to achieve lasting recovery. This is enlightening and optimistic reading for anyone who has wrestled with addiction either personally or professionally.

People use drugs for many different reasons, including the pursuit of "high," social factors and self-medication of other conditions. Many millions of people are addicted to at least one substance, and the cost of addiction is immense, at both the individual and societal levels. Neurocircuitry of Addiction is the first book of its kind, with a focus on addiction neuroscience from a neural circuit perspective. This book begins with a primer on circuit-based neuroscience that equips the reader with an understanding of the applications described throughout the book. Each subsequent chapter positions a different brain region at the "center" of addiction neurocircuitry and goes on to describe the anatomical connectivity of that brain region, how those circuits are affected by drug exposure, and the role of those circuits in controlling addiction-related behaviors. All chapters of this book are written by content experts for a target audience that has some basic neuroscience background, but no prior in-depth knowledge regarding the neurocircuitry of addiction. - Reviews the circuit-based tools that are used by scientists to investigate neural circuit function - Describes how acute and chronic alcohol and drug exposure affect neural circuit function - Describes the state of the science regarding the role of specific neural circuis in drug addiction - Chapters include data from both human neuroscience and animal models

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.

Drug addiction is a chronically relapsing mental illness involving severe motivational disturbances and loss of behavioral control leading to personal dev- tation. The disorder af?icts millions of people, often co-occurring with other mental illnesses with enormous social and economic costs to society. Several decades of research have established that drugs of abuse hijack the brain’s natural reward substrates, and that chronic drug use causes aberrant alterations in these rewa- processing systems. Such aberrations may be demonstrated at the cellular, neu- transmitter, and regional levels of information processing using either animal models or neuroimaging in humans following chronic drug exposure. Behaviorally, these neural aberrations manifest as exaggerated, altered or dysfunctional expr- sion of learned behavioral responses related to the pursuit of drug rewards, or to environmental factors that precipitate craving and relapse during periods of drug withdrawal. Current research efforts are aimed at understanding the associative and causal relationships between these neurobiological and behavioral events, such that treatment options will ultimately employ therapeutic amelioration of neural de?cits and restoration of normal brain processing to promote efforts to abstain from further drug use. The Behavioral Neuroscience of Drug Addiction, part of the Springer series on Current Topics in Behavioral Neurosciences, contains scholarly reviews by noted experts on multiple topics from both basic and clinical neuroscience ?elds.
