What Is Addiction?
Addiction, clinically referred to as substance use disorder (SUD), is a chronic, relapsing brain disorder characterized by compulsive substance use despite harmful consequences. It is recognized by the American Society of Addiction Medicine (ASAM) and the National Institute on Drug Abuse (NIDA) as a medical condition, not a moral failing. For a deeper look at the neuroscience and clinical framework, see our guide on what addiction actually is.
The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), published by the American Psychiatric Association, is the standard reference used to diagnose substance use disorders. It classifies addiction on a spectrum from mild to severe, based on the number of diagnostic criteria met within a 12-month period.
According to the 2024 National Survey on Drug Use and Health (NSDUH), approximately 48.4 million Americans aged 12 or older had a substance use disorder in the past year. Of those, only about 19.3% received treatment. This highlights the significant gap between those who need help and those who access it.
Common Warning Signs of Addiction
Addiction rarely appears overnight. It typically develops gradually, and early warning signs can be easy to rationalize or overlook. If several of the following patterns apply to you or someone you know, it may indicate a developing or existing substance use disorder.
Loss of Control
Using more of the substance or for longer periods than you originally intended, repeatedly.
Social Withdrawal
Pulling away from family, friends, and activities you once enjoyed in favor of substance use.
Tolerance and Withdrawal
Needing increasing amounts to achieve the same effect, or experiencing physical symptoms when not using.
Risky Behavior
Continuing to use despite legal trouble, health problems, relationship damage, or physical danger.
Failed Attempts to Quit
Wanting to cut down or stop but being unable to do so despite genuine effort and motivation.
Preoccupation
Spending significant time thinking about, obtaining, using, or recovering from the substance.
DSM-5 Self-Assessment Checklist
The DSM-5 defines 11 criteria for diagnosing a substance use disorder. While only a qualified professional can provide a formal diagnosis, reviewing these criteria honestly can help you understand whether your substance use has become problematic.
Consider the past 12 months. How many of these statements apply to you?
Impaired Control
You often use the substance in larger amounts or for a longer period than you originally planned.
You have a persistent desire or have made unsuccessful efforts to reduce or control your substance use.
You spend a great deal of time obtaining, using, or recovering from the effects of the substance.
You experience strong urges or desires to use the substance, sometimes triggered by people, places, or emotions.
Social Impairment
Your substance use results in failure to meet major responsibilities at work, school, or home.
You continue using despite persistent social or relationship problems caused or worsened by the substance.
Important social, occupational, or recreational activities are reduced or abandoned because of substance use.
Risky Use
You repeatedly use the substance in situations where it is physically dangerous. This includes driving or operating machinery.
You continue using despite knowing it is causing or worsening a physical or psychological condition.
Pharmacological Criteria
You need significantly more of the substance to achieve the desired effect, or the same amount produces a noticeably diminished effect.
You experience withdrawal symptoms when not using the substance, or you use the substance (or a similar one) to avoid or relieve withdrawal symptoms.
Understanding Your Results
Even a mild substance use disorder is a medical condition that warrants professional consultation. This checklist is not a substitute for clinical evaluation.
Who Is at Risk?
Addiction does not discriminate, but certain factors make some individuals more vulnerable than others. Understanding these risk factors can help you contextualize your own relationship with substances.
Genetics
Research shows that genetic factors account for 40% to 60% of a person's vulnerability to addiction. Family history of substance use disorders significantly increases risk.
National Institute on Drug Abuse (NIDA)Early Exposure
Using substances during adolescence, when the prefrontal cortex is still developing, dramatically increases the likelihood of developing a disorder later in life.
NIDA, "Drugs, Brains, and Behavior"Mental Health Conditions
Co-occurring mental health disorders, including depression, anxiety, PTSD, and ADHD, are strongly associated with higher rates of substance use. This is clinically known as a dual diagnosis.
SAMHSA, 2024 NSDUH ReportTrauma and Childhood Experiences
Individuals who have experienced childhood trauma, neglect, abuse, or household dysfunction face significantly elevated risks of developing addiction as a coping mechanism.
CDC ACE StudySocial Environment
Peer pressure, social norms, easy access to drugs or alcohol, and lack of parental supervision all contribute to increased vulnerability.
NIDA Risk Factors ResearchMethod of Use
The route of administration matters. Smoking or injecting substances delivers them to the brain more rapidly compared to swallowing, which increases addiction potential.
NIDA, "Principles of Drug Addiction Treatment"How Addiction Changes the Brain
Understanding the neuroscience behind addiction can help remove stigma. It explains why quitting is so difficult, even when a person genuinely wants to stop.
The Reward Circuit
Addictive substances trigger the release of dopamine in the brain's reward center at levels far exceeding natural rewards. This creates an intense sensation of pleasure that the brain is powerfully motivated to repeat.
The Brain Adapts
With repeated use, the brain reduces its natural dopamine production and decreases the number of receptors. As a result, the person needs more of the substance to achieve the same effect. This state is called anhedonia.
Decision-Making Breaks Down
Chronic substance use impairs the prefrontal cortex. This is the brain region responsible for judgment, impulse control, and decision-making. This makes it biologically harder to stop, even when the person understands the consequences.
Cravings Become Automatic
The brain becomes sensitized to environmental cues associated with substance use. Encountering specific people, places, or emotional states can cause intense, involuntary cravings, even after long periods of abstinence.
What to Do If You Think You Have an Addiction
If you recognized yourself in the signs or criteria above, know that acknowledging a problem is one of the most courageous steps you can take. Addiction is a treatable medical condition, and help is available.
Acknowledge Without Shame
Addiction is a medical condition, not a character flaw. Recognizing that your substance use has become problematic is the critical first step, and it takes strength.
Talk to a Healthcare Professional
Contact your primary care doctor, a psychiatrist, or a licensed addiction counselor. They can provide a confidential clinical assessment and recommend appropriate treatment based on your specific needs.
Call a Free Helpline
If you're unsure where to start, the SAMHSA National Helpline (1-800-662-4357) is free, confidential, and available 24/7. They provide referrals to local treatment facilities, support groups, and community-based organizations. You can also call or text 988 for crisis support.
Explore Treatment Options
Treatment is not one-size-fits-all. Options include medical detox, inpatient rehab, outpatient programs, medication-assisted treatment (MAT), and behavioral therapy. The right approach depends on the substance, severity, and your personal circumstances.
Build a Support Network
Recovery is not a solo journey. Consider connecting with support groups such as 12-step programs (AA, NA), SMART Recovery, or faith-based recovery groups. Confide in trusted friends or family members who can support your path.

Find Treatment CentersFrequently Asked Questions
Is addiction a choice or a disease?
Addiction is classified as a chronic brain disorder by the American Society of Addiction Medicine (ASAM) and the National Institute on Drug Abuse (NIDA). While the initial decision to use a substance is voluntary, repeated use causes changes in brain chemistry and structure that impair self-control and the ability to resist cravings. It is not a moral failing or a lack of willpower.
Can I self-diagnose an addiction?
Self-assessment tools, such as the DSM-5 criteria checklist, can help you recognize problematic patterns and decide whether to seek professional help. However, a formal substance use disorder diagnosis can only be made by a qualified healthcare professional. This typically includes a doctor, psychiatrist, or licensed addiction counselor who can properly evaluate your situation.
What is the difference between dependence and addiction?
Physical dependence refers to the body adapting to a substance, leading to tolerance and withdrawal symptoms when stopping. Addiction goes further. It includes compulsive substance-seeking behavior despite harmful consequences. You can be physically dependent on a medication without being addicted, but addiction typically involves dependence.
How many criteria do I need to meet to have a substance use disorder?
According to the DSM-5, meeting at least 2 of the 11 criteria within a 12-month period qualifies as a substance use disorder. The severity is classified as mild (2–3 criteria), moderate (4–5 criteria), or severe (6 or more criteria). Even a mild diagnosis warrants professional consultation.
Can you be addicted to something other than drugs or alcohol?
Yes. Behavioral addictions, such as gambling disorder, are recognized in the DSM-5. Research also suggests that compulsive behaviors related to internet use, gaming, shopping, and food may share similar neurological pathways as substance addictions, though not all are formally classified as disorders yet.
What should I do if I think a loved one has an addiction?
Approach them with compassion, not judgment. Express your concerns using specific examples of how their behavior has affected them and others. Avoid enabling behaviors. Encourage them to speak with a healthcare professional. You can also contact SAMHSA's National Helpline (1-800-662-4357) for free, confidential guidance on how to help.
Is it possible to recover from addiction?
Absolutely. Millions of people achieve long-term recovery from addiction every year. Treatment approaches, including medication-assisted treatment, behavioral therapy, and peer support groups, have strong evidence supporting their effectiveness. Recovery is a process, and many people build fulfilling, substance-free lives with the right support.
Does insurance cover addiction treatment?
Under the Affordable Care Act and the Mental Health Parity and Addiction Equity Act, most health insurance plans are required to cover substance use disorder treatment. This typically includes detox, inpatient and outpatient rehab, therapy, and medication-assisted treatment. Contact your insurer or a treatment center to verify your specific benefits.
