Molecular Neurobiology of Addiction Recovery


Book Description

Humans are biologically programmed to seek out pleasurable experiences. These experiences are processed in the mesolimbic system, also referred to as the "reward center" of the brain, where a number of chemical messengers work in concert to provide a net release of dopamine in the Nucleus Accumbens. In some genetically predisposed individuals, addiction occurs when the mechanisms of the mesolimbic system are disrupted by the use of various drugs of abuse. Since Alcoholics Anonymous was founded in 1935, it's 12 step program of spiritual and character development has helped countless alcoholics and drug addicts curb their self-destructive behaviors. However, the program was developed at a time when comparatively little was known about the function of the brain and it has never been studied scientifically. This is the first book to take a systematic look at the molecular neurobiology associated with each of the 12 steps and to review the significant body of addiction research literature that is pertinent to the program.​

Dispelling the Myths About Addiction


Book Description

Every year about half a million men, women, and children in the United States die from the effects of using nicotine, alcohol, and illegal drugs: one of every four American deaths. Yet research to solve this terrible problem is often perceived as less important than other types of biomedical investigation. Focusing on four major classes of drugs with the greatest social and economic impactâ€"nicotine, alcohol, opioids, and stimulantsâ€"Dispelling the Myths About Addiction examines what is known about addiction and what is needed to develop a talented cadre of investigators and to educate the public about addiction research. The committee explores these areas: Economic costs of addiction. What has been learned about addiction from research into basic neurobiology and the brain, psychosocial and behavioral factors, and epidemiology. Education and training of researchers and the research infrastructure. Public perceptions and their impact on public policy in this field. This volume outlines the challenges and opportunities in addiction research today and makes recommendations to educators, treatment professionals, public and private institutions, and others for how to build support for addiction research and treatment.

Addiction


Book Description

In a book sure to inspire controversy, Gene Heyman argues that conventional wisdom about addiction—that it is a disease, a compulsion beyond conscious control—is wrong. Drawing on psychiatric epidemiology, addicts’ autobiographies, treatment studies, and advances in behavioral economics, Heyman makes a powerful case that addiction is voluntary. He shows that drug use, like all choices, is influenced by preferences and goals. But just as there are successful dieters, there are successful ex-addicts. In fact, addiction is the psychiatric disorder with the highest rate of recovery. But what ends an addiction? At the heart of Heyman’s analysis is a startling view of choice and motivation that applies to all choices, not just the choice to use drugs. The conditions that promote quitting a drug addiction include new information, cultural values, and, of course, the costs and benefits of further drug use. Most of us avoid becoming drug dependent, not because we are especially rational, but because we loathe the idea of being an addict. Heyman’s analysis of well-established but frequently ignored research leads to unexpected insights into how we make choices—from obesity to McMansionization—all rooted in our deep-seated tendency to consume too much of whatever we like best. As wealth increases and technology advances, the dilemma posed by addictive drugs spreads to new products. However, this remarkable and radical book points to a solution. If drug addicts typically beat addiction, then non-addicts can learn to control their natural tendency to take too much.

Medications for Opioid Use Disorder Save Lives


Book Description

The opioid crisis in the United States has come about because of excessive use of these drugs for both legal and illicit purposes and unprecedented levels of consequent opioid use disorder (OUD). More than 2 million people in the United States are estimated to have OUD, which is caused by prolonged use of prescription opioids, heroin, or other illicit opioids. OUD is a life-threatening condition associated with a 20-fold greater risk of early death due to overdose, infectious diseases, trauma, and suicide. Mortality related to OUD continues to escalate as this public health crisis gathers momentum across the country, with opioid overdoses killing more than 47,000 people in 2017 in the United States. Efforts to date have made no real headway in stemming this crisis, in large part because tools that already existâ€"like evidence-based medicationsâ€"are not being deployed to maximum impact. To support the dissemination of accurate patient-focused information about treatments for addiction, and to help provide scientific solutions to the current opioid crisis, this report studies the evidence base on medication assisted treatment (MAT) for OUD. It examines available evidence on the range of parameters and circumstances in which MAT can be effectively delivered and identifies additional research needed.
