What Is Addiction?

Addiction is a chronic medical condition involving the continued use of alcohol or other drugs despite harmful consequences. It can affect a person’s health, relationships, work, education, and daily life.

Addiction is not caused by a lack of character, morality, or willpower. Genetics, brain chemistry, mental health, trauma, environment, substance exposure, and access to care can all influence a person’s risk.

Like other chronic conditions, addiction may involve periods of improvement and recurrence. With appropriate treatment and ongoing support, many people successfully manage substance use disorders and lead healthy, productive lives.

Signs of Addiction

The signs of addiction can vary depending on the person and the substance involved. Possible signs of a substance use disorder may include:

• Difficulty reducing or controlling alcohol or drug use
• Strong cravings or spending significant time obtaining, using, or recovering from a substance
• Continuing to use a substance despite physical, emotional, social, work, or school-related problems
• Needing more of a substance to experience the same effects
• Experiencing withdrawal symptoms when use is reduced or stopped
• Giving up important activities or responsibilities because of substance use
• Using alcohol or drugs in situations where doing so may be dangerous

No single behavior confirms that someone has an addiction. A qualified healthcare professional can evaluate patterns of substance use, related health concerns, and other factors to determine whether additional assessment or treatment may be appropriate.

Signs of Alcohol or Drug Use Among Teens

Alcohol and drug use during adolescence remains a public health concern. Early substance use is associated with a greater risk of later problems, particularly because the brain continues developing into early adulthood.

Possible warning signs in a teenager may include changes in:

• Physical health: fatigue, frequent illness, or red or glazed eyes
• Mood or behavior: irritability, withdrawal, secrecy, or sudden personality changes
• School engagement: declining grades, absences, or loss of interest
• Social relationships: changes in peer groups, isolation, or legal problems

No single sign confirms alcohol or drug use. Patterns and significant changes over time may warrant a supportive conversation with the young person and guidance from a qualified healthcare professional.

Genetic Risk for Addiction

Genetics can influence vulnerability to addiction, but genes do not determine a person’s future. Environment, stress, trauma, mental health, substance exposure, and access to support also affect risk.

Protective factors—including stable relationships, emotional support, prevention education, and early intervention—may help reduce the likelihood of substance-related problems.

Understanding Risky Drinking

No level of alcohol use is completely free from health risk. For adults who choose to drink, current public-health guidance defines moderate drinking as no more than two drinks in a day for men and no more than one drink in a day for women. Drinking less or not drinking reduces health risks.

Some people should not drink alcohol, including people who:

• Are pregnant or may be pregnant
• Are younger than 21
• Take medications that interact with alcohol
• Have certain medical conditions
• Are unable to control the amount they drink
• Are recovering from an alcohol use disorder
• Plan to drive or participate in activities requiring coordination and alertness

If you are concerned about your drinking, consider whether you have felt a need to cut down, whether others have expressed concern, whether drinking has caused guilt or regret, or whether you use alcohol to cope with stress or discomfort.

Answering yes to one or more of these questions does not establish a diagnosis, but it may be helpful to speak with a healthcare professional.

Addiction Treatment and Recovery

Addiction treatment works, particularly when care is individualized and sustained for an appropriate length of time. People who participate in treatment may reduce or stop substance use, improve their physical and mental health, strengthen relationships, and improve daily functioning.

Effective addiction treatment may include:

• Behavioral therapies delivered individually, in groups, or with families
• Medications for certain substance use disorders, when appropriate
• Medical support for withdrawal and other health complications
• Treatment for co-occurring mental and physical health conditions
• Social, family, peer, and recovery support

Many people with substance use disorders also experience depression, anxiety, trauma-related symptoms, or other health conditions. Coordinated care that addresses the whole person can be an important part of treatment and recovery.

How Long Does Addiction Treatment Take?

There is no single treatment timeline that works for everyone. The appropriate length and level of care depend on the person’s health, substance use, circumstances, treatment response, and available support.

Recovery is an ongoing process rather than a single event. Continued care and follow-up—whether formal or informal—can help people maintain progress and respond to changing needs.

Can Someone Get Treatment Without Health Insurance?

Yes. Addiction treatment options may be available to people who do not have health insurance.

California residents can contact the California Department of Health Care Services for information about Medi-Cal and publicly funded behavioral health services.

The SAMHSA National Helpline also provides free, confidential treatment referrals at 1-800-662-HELP (4357). Some treatment programs may offer sliding-scale fees or payment plans.

How Do Mutual-Support Groups Fit Into Treatment?

Mutual-support groups such as Alcoholics Anonymous and Narcotics Anonymous can offer peer support, community connection, and accountability during and after formal treatment.

Different approaches work for different people. Mutual-support groups may be one part of a broader recovery plan, but they do not replace medical or behavioral healthcare when professional treatment is needed.

Relapse and Ongoing Care

A return to substance use does not necessarily mean addiction treatment has failed. Because addiction is a chronic condition, symptoms can recur, just as they can with conditions such as diabetes, asthma, or high blood pressure.

Relapse or a return to use can indicate that treatment needs to be adjusted, resumed, or strengthened. It should be approached as a health and safety concern—not as a moral or personal failure.

Ongoing care may involve changes to medications, counseling, recovery supports, the level of care, or the treatment plan. A healthcare professional can help reassess current needs and recommend appropriate next steps.

How to Support Someone With Addiction

Supporting someone with addiction can be difficult. Begin by approaching the person with compassion and without judgment. Addiction is a medical condition, and stigma can make it harder for people to ask for help.

Helpful ways to offer support may include:

• Listening without blaming, threatening, or shaming
• Learning about substance use disorders and available treatment
• Encouraging an evaluation by a qualified healthcare professional
• Offering practical help with finding care or attending an appointment
• Setting healthy boundaries that protect your own safety and well-being
• Seeking support for yourself from a healthcare professional, counselor, or family-support resource

You cannot force another person to recover, but compassionate support and access to evidence-based care can make a meaningful difference.

If someone may be experiencing an overdose or another medical emergency, call 911 immediately.

Finding an Addiction Medicine Doctor

An addiction medicine doctor can assess substance use disorders, explain evidence-based treatment options, address withdrawal and medical complications, and coordinate care across medical, behavioral health, and social services.

When choosing a doctor, consider asking about the physician’s addiction medicine training, board certification, experience treating the relevant substance use disorder, treatment approach, and ability to coordinate care for other health conditions.

Addiction FAQs

What are common signs of addiction?

Common signs may include difficulty controlling substance use, strong cravings, withdrawal symptoms, increasing tolerance, and continued use despite health, relationship, work, school, or legal consequences. Because the signs vary, a healthcare professional should conduct a complete assessment before diagnosing a substance use disorder.

Is addiction a disease?

Yes. Addiction, also called a substance use disorder, is a chronic and treatable medical condition. Biological, psychological, environmental, and social factors can all contribute to its development. Addiction is not caused by a lack of character or willpower.

Does addiction treatment work?

Yes. Evidence-based addiction treatment can help people reduce or stop substance use, improve their health, and regain stability in their daily lives. Treatment is most effective when it is tailored to the individual and adjusted as their needs change.

Does relapse mean treatment failed?

No. A return to use can occur during recovery and may indicate that treatment should be resumed, adjusted, or strengthened. It does not mean that the person or the treatment has failed.

How do I choose an addiction medicine doctor?

Look for a physician with appropriate addiction medicine training and experience who offers evidence-based, respectful, and individualized care. You may also want to ask about board certification, available treatment options, care coordination, and experience addressing co-occurring medical or mental health conditions.
