The Effects of Drug Addiction on the Brain and Body

Signs of drug addiction, effects of drug addiction.

Drug addiction is a treatable, chronic medical disease that involves complex interactions between a person’s environment, brain circuits, genetics, and life experiences.

People with drug addictions continue to use drugs compulsively, despite the negative effects.

Substance abuse has many potential consequences, including overdose and death. Learn about the effects of drug addiction on the mind and body and treatment options that can help.

Verywell / Theresa Chiechi

Drug Abuse vs. Drug Addiction

While the terms “drug abuse” and “drug addiction” are often used interchangeably, they're different. Someone who abuses drugs uses a substance too much, too frequently, or in otherwise unhealthy ways. However, they ultimately have control over their substance use.

Someone with a drug addiction uses drugs in a way that affects many parts of their life and causes major disruptions. They continue to use drugs compulsively despite the negative consequences.

The signs of drug abuse and addiction include changes in behavior, personality, and physical appearance. If you’re concerned about a loved one’s substance use, here are some of the red flags to watch out for:

• Changes in school or work performance
• Secretiveness 
• Relationship problems
• Risk-taking behavior
• Legal problems
• Aggression 
• Mood swings
• Changes in hobbies or friends
• Sudden weight loss or gain
• Unexplained odors on the body or clothing

Drug Addiction in Men and Women

Men and women are equally likely to develop drug addictions. However, men are more likely than women to use illicit drugs, die from a drug overdose, and visit an emergency room for addiction-related health reasons. Women are more susceptible to intense cravings and repeated relapses.

People can become addicted to any psychoactive ("mind-altering") substance. Common addictive substances include alcohol , tobacco ( nicotine ), stimulants, hallucinogens, and opioids .

Many of the effects of drug addiction are similar, no matter what substance someone uses. The following are some of the most common effects of drug addiction.

Effects of Drug Addiction on the Body

Drug addiction can lead to a variety of physical consequences ranging in seriousness from drowsiness to organ damage and death:

• Shallow breathing
• Elevated body temperature
• Rapid heart rate
• Increased blood pressure
• Impaired coordination and slurred speech
• Decreased or increased appetite
• Tooth decay
• Skin damage
• Sexual dysfunction
• Infertility
• Kidney damage
• Liver damage and cirrhosis
• Various forms of cancer
• Cardiovascular problems
• Lung problems
• Overdose and death

If left untreated drug addiction can lead to serious, life-altering effects on the body.

Dependence and withdrawal also affect the body:

• Physical dependence : Refers to the reliance on a substance to function day to day. People can become physically dependent on a substance fairly quickly. Dependence does not always mean someone is addicted, but the longer someone uses drugs, the more likely their dependency is to become an addiction.
• Withdrawal : When someone with a dependence stops using a drug, they can experience withdrawal symptoms like excessive sweating, tremors, panic, difficulty breathing, fatigue , irritability, and flu-like symptoms.

Overdose Deaths in the United States

According to the Centers for Disease Control and Prevention (CDC), over 100,000 people in the U.S. died from a drug overdose in 2021.

Effects of Drug Addiction on the Brain

All basic functions in the body are regulated by the brain. But, more than that, your brain is who you are. It controls how you interpret and respond to life experiences and the ways you behave as a result of undergoing those experiences.

Drugs alter important areas of the brain. When someone continues to use drugs, their health can deteriorate both psychologically and neurologically.

Some of the most common mental effects of drug addiction are:

• Cognitive decline
• Memory loss
• Mood changes and paranoia
• Poor self/impulse control
• Disruption to areas of the brain controlling basic functions (heart rate, breathing, sleep, etc.)

Effects of Drug Addiction on Behavior

Psychoactive substances affect the parts of the brain that involve reward, pleasure, and risk. They produce a sense of euphoria and well-being by flooding the brain with dopamine .

This leads people to compulsively use drugs in search of another euphoric “high.” The consequences of these neurological changes can be either temporary or permanent. 

• Difficulty concentrating
• Irritability 
• Angry outbursts
• Lack of inhibition 
• Decreased pleasure/enjoyment in daily life (e.g., eating, socializing, and sex)
• Hallucinations

Help Someone With Drug Addiction

If you suspect that a loved one is experiencing drug addiction, address your concerns honestly, non-confrontationally, and without judgment. Focus on building trust and maintaining an open line of communication while setting healthy boundaries to keep yourself and others safe. If you need help, contact the SAMHSA National Helpline at 1-800-662-4357.

Effects of Drug Addiction on an Unborn Child

Drug addiction during pregnancy can cause serious negative outcomes for both mother and child, including:

• Preterm birth
• Maternal mortality

Drug addiction during pregnancy can lead to neonatal abstinence syndrome (NAS) . Essentially, the baby goes into withdrawal after birth. Symptoms of NAS differ depending on which drug has been used but can include:

• Excessive crying
• Sleeping and feeding issues

Children exposed to drugs before birth may go on to develop issues with behavior, attention, and thinking. It's unclear whether prenatal drug exposure continues to affect behavior and the brain beyond adolescence.  

While there is no single “cure” for drug addiction, there are ways to treat it. Treatment can help you control your addiction and stay drug-free. The primary methods of treating drug addiction include:

• Psychotherapy : Psychotherapy, such as cognitive behavioral therapy (CBT) or family therapy , can help someone with a drug addiction develop healthier ways of thinking and behaving.
• Behavioral therapy : Common behavioral therapies for drug addiction include motivational enhancement therapy (MET) and contingency management (CM). These therapy approaches build coping skills and provide positive reinforcement.
• Medication : Certain prescribed medications help to ease withdrawal symptoms. Some examples are naltrexone (for alcohol), bupropion (for nicotine), and methadone (for opioids).
• Hospitalization : Some people with drug addiction might need to be hospitalized to detox from a substance before beginning long-term treatment.
• Support groups : Peer support and self-help groups, such as 12-step programs like Alcoholics Anonymous, can help people with drug addictions find support, resources, and accountability.

A combination of medication and behavioral therapy has been found to have the highest success rates in preventing relapse and promoting recovery. Forming an individualized treatment plan with your healthcare provider's help is likely to be the most effective approach.

Drug addiction is a complex, chronic medical disease that results in compulsive use of psychoactive substances despite the negative consequences.

Some effects of drug abuse and addiction include changes in appetite, mood, and sleep patterns. More serious health issues such as cognitive decline, major organ damage, overdose, and death are also risks. Addiction to drugs while pregnant can lead to serious outcomes for both mother and child.

Treatment for drug addiction may involve psychotherapy , medication, hospitalization, support groups, or a combination.

If you or someone you know is experiencing substance abuse or addiction, contact the Substance Abuse and Mental Health Services Administration (SAMHSA) National Helpline at 1-800-662-4357.
