What Is Substance Abuse?

Learn More About Substance Abuse

Substance abuse occurs when an individual purposefully and repeatedly ingests a substance for reasons outside of its intended use, or to achieve a high. Abusing substances like drugs or alcohol can lead to addiction, and puts you at risk for what is known clinically as a substance use disorder.

When you continue to engage in substance use, you may soon find yourself unable to control your behavior. You may experience damage to your physical and mental health, difficulty performing at work or school, and instability in your relationships.

Fortunately, substance abuse and addiction are highly treatable. With help from a quality treatment program, you or someone you care about can overcome a substance use disorder and lead a full, healthy life.

Statistics

Statistics on Substance Abuse

The National Institute on Drug Abuse (NIDA) and the Substance Abuse and Mental Health Services Administration (SAMHSA) have reported that as many as 90% of Americans will abuse alcohol or another drug at least once in their lives, and more than 20 million Americans are currently struggling with addiction. The three most commonly abused drugs in the U.S. are alcohol, marijuana, and prescription medications. Sadly, fewer than 2 out of 10 addicted individuals will receive professional treatment for their substance abuse problem.

Causes of Substance Abuse

Causes of Drug & Alcohol Addiction

There is no one definitive reason for why someone struggles with substance abuse. But there are a few factors that are known to contribute to the problem, including:

Genetic: Having a close family member, like a sibling or parent, with a substance use disorder may increase the odds that you’ll develop a problem with addiction.

Brain Structures: There is some research to indicate that there are certain similarities in the brain structures of individuals who struggle with substance abuse that are different from those of people who do not use substances.

Environmental: Being exposed to drug and/or alcohol abuse, especially early in life, may put you at greater risk for abusing drugs or alcohol.

Psychological: Dealing with emotional pain, perhaps due to trauma or untreated mental illness, causes some people to self-medicate with drugs or alcohol.
