Drug Addiction and Drug Policy: The Struggle to Control Dependence

The National Institute of Drug Abuse NIDA defines addiction as a chronic, relapsing brain disease that is characterized by compulsive drug seeking and use, despite harmful consequences. Other examples of chronic diseases include asthma, diabetes, and heart disease.

It is critical that treatment simultaneously addresses any co-occurring neurological or psychological disorders that are known to drive vulnerable individuals to experiment with drugs and become addicted in the first place. Learn more about the connection between addiction and mental health. Respected institutions like the American Medical Association and the American Society of Addiction Medicine define addiction as a disease.

A disease is a condition that changes the way an organ functions. Addiction does this to the brain, changing the brain on a physiological level. It literally alters the way the brain works, rewiring its fundamental structure. Although there is no cure for addiction, there are many evidence-based treatments that are effective at managing the illness.

Like all chronic illnesses, addiction requires ongoing management that may include medication, therapy, and lifestyle change.

Once in recovery from substance use disorder, a person can go on to live a healthy and successful life. Addiction is treatable, and recovery should be the expected outcome of treatment. The human brain is wired to reward us when we do something pleasurable.

Exercising, eating, and other pleasurable behaviors directly linked to our health and survival trigger the release of a neurotransmitter called dopamine. It teaches our brains to repeat the behavior. Drugs trigger that same part of the brain—the reward system. But they do it to an extreme extent, rewiring the brain in harmful ways. When someone takes a drug, their brain releases extreme amounts of dopamine—way more than gets released as a result of a natural pleasurable behavior.

The brain overreacts, reducing dopamine production in an attempt to normalize these sudden, sky-high levels the drugs have created. And this is how the cycle of addiction begins. Once the brain has been altered by drug use, it requires more and more drugs just to function at a baseline level. Someone in withdrawal feels absolutely terrible: depressed, despondent, and physically ill.

Brain imaging studies from drug-addicted individuals show physical, measurable changes in areas of the brain that are critical to judgment, decision making, learning and memory, and behavior control.

Scientists believe that these changes alter the way the brain works, and may help explain the compulsive and destructive behaviors of addiction. A promising student might see his grades slip. A bubbly social butterfly might suddenly have trouble getting out of bed. A trustworthy sibling might start stealing or lying. Cravings take over. These cravings are painful, constant, and distracting. Especially given the intensity of withdrawal symptoms, the body wants to avoid being in withdrawal at all costs.

Some of us have the genes that increase our risk of addiction, even after just a few uses. I never knew that when I was raising my son, and I wish that I did. But at some point during use, a switch gets flipped within the brain and the decision to use is no longer voluntary. Anyone who tries a substance can become addicted, and research shows that the majority of Americans are at risk of developing addiction. After initial exposure, no one chooses how their brain will react to drugs or alcohol.

Addiction is not a choice. Harmful consequences, shame, and punishment are simply not effective ways to end addiction. Like other chronic illnesses, such as asthma or type 2 diabetes, ongoing management of addiction is required for long-term recovery. This can include medication, behavioral therapy, peer-support, and lifestyle modifications. Support our work. Science of Addiction. Addiction is a chronic brain disease.

Get the facts about how addiction affects our bodies, our brains, and our behavior, while learning about the biological and psychological factors that often drive addiction. What is addiction? The latest science points to three main factors.

Exactly how genetics factor into addiction, and what we could do to protect against their influence, is something scientists are actively researching right now. Research shows that growing up in an environment with older adults who use drugs or engage in criminal behavior is a risk factor for addiction. Protective factors like a stable home environment and supportive school are all proven to reduce the risk. Addiction can develop at any age.

But research shows that the earlier in life a person tries drugs, the more likely that person is to develop addiction. Introducing drugs to the brain during this time of growth and change can cause serious, long-lasting damage. References 1. National Institute on Drug Abuse. Definition of Addiction.

Drugs, Addiction, and the Brain

Drugs, Addiction, and the Brain explores the molecular, cellular, and neurocircuitry systems in the brain that are responsible for drug addiction. Common neurobiological elements are emphasized that provide novel insights into how the brain mediates the acute rewarding effects of drugs of abuse and how it changes during the transition from initial drug use to compulsive drug use and addiction. The book provides a detailed overview of the pathophysiology of the disease. The information provided will be useful for neuroscientists in the field of addiction, drug abuse treatment providers, and undergraduate and postgraduate students who are interested in learning the diverse effects of drugs of abuse on the brain. He has made contributions to our understanding of the anatomical connections of the emotional systems and the neurochemistry of emotional function.
