Drug Addiction Statistics in the United States

Drug addiction statistics measure drug exposure, substance use disorder, treatment participation, and overdose harm across different populations. In 2024, SAMHSA estimated that 28.2 million people aged 12 or older had a drug use disorder, while final CDC data recorded a 26.2% decline in the age-adjusted drug overdose death rate from 2023 to 2024. Use does not establish a disorder, a disorder does not establish overdose, and an overdose count does not measure treatment need by itself.

How Many Americans Have a Drug Use Disorder?

SAMHSA estimated that 28.2 million people aged 12 or older had a drug use disorder in 2024. The National Survey on Drug Use and Health covers the civilian noninstitutionalized population and applies DSM-5 criteria to respondents who reported using the relevant drug during the previous year.

2024 measure	People aged 12+	Meaning
Any substance use disorder	48.4 million	Alcohol use disorder, drug use disorder, or both
Drug use disorder	28.2 million	A disorder involving at least one covered drug
Marijuana use disorder	20.6 million	Disorder among past-year marijuana users
Opioid use disorder	4.8 million	Heroin or prescription-opioid use disorder
CNS stimulant use disorder	4.3 million	Cocaine, methamphetamine, or prescription-stimulant disorder
Tranquilizer or sedative use disorder	2.1 million	Prescription tranquilizer or sedative disorder

How Common Is Drug Use in the United States?

About 73.6 million people aged 12 or older used an illicit drug during the previous year in 2024, representing 25.5% of that population. NSDUH includes marijuana, cocaine, heroin, hallucinogens, inhalants, methamphetamine, and misuse of prescription psychotherapeutic drugs. Prevalence counts exposure; impaired control, risky use, social impairment, and pharmacologic effects distinguish drug addiction and substance use disorder.

How Many People Receive Addiction Treatment?

Among people with a past-year substance use disorder, 5.9 million received substance use treatment in 2024 and 42.4 million did not. The 12.3% treatment rate identifies an access gap but does not explain why an individual entered or did not enter care.

Clinical severity, withdrawal risk, medical stability, and daily functioning determine the appropriate level of rehabilitation. A professional assessment connects those factors to treatment for alcohol and drug use disorders after treatment need is established.

What Do the Latest Drug Overdose Statistics Show?

The age-adjusted U.S. drug overdose death rate fell from 31.3 deaths per 100,000 people in 2023 to 23.1 in 2024, a 26.2% decline. The decrease was substantial, the 2024 burden remained severe, and national improvement did not eliminate differences by drug or population.

Call 911 immediately for suspected overdose, stopped or irregular breathing, unconsciousness, blue or gray skin, or inability to wake. Administer naloxone when opioid exposure is known or suspected, repeat the dose according to product instructions, and remain with the person until emergency responders arrive.

Death certificates frequently list more than one drug, so opioid, cocaine, and psychostimulant categories overlap. Drug overdose statistics separate polysubstance involvement and provisional counts from final mortality data.

Long-term comparisons require consistent drug categories and reporting periods. The historical heroin statistics series separates heroin-specific use, treatment, and mortality measures from current all-opioid totals.

How Do Drug Statistics Differ by Age?

Past-year substance use disorder affected 25.9% of adults aged 18 to 25, 16.4% of adults aged 26 or older, and 7.8% of adolescents aged 12 to 17 in 2024. Age changes prevalence, substance patterns, and care access; it does not determine an individual's diagnosis or recovery outlook.

How Should Drug Addiction Statistics Be Interpreted?

A reliable comparison names the measure, population, period, and source. NSDUH surveys households, CDC mortality data use death certificates, hospital datasets count encounters, and justice datasets count arrests or incarcerated people.

Social anxiety statistics by state report normalized Google search interest; they measure relative search behavior rather than diagnosed prevalence or treatment demand.

• Use prevalence measures reported consumption.
• Disorder prevalence measures diagnostic criteria.
• Treatment participation measures receipt of care, not effectiveness.
• Overdose mortality measures deaths, not all overdoses.
• Justice data reflect enforcement and court outcomes as well as behavior.

Drug-related crime statistics distinguish arrests, convictions, incarceration, and diversion.

Workplace addiction statistics separate prevalence, missed workdays, recovery, and FMLA protection.

What Are Common Questions About Drug Statistics?

Common questions distinguish drug use from a disorder, provisional overdose counts from final data, and population estimates from individual treatment decisions.

What Is the Difference Between Drug Use and Drug Addiction?

Drug use records exposure. Drug addiction describes a substance use disorder marked by clinically significant impairment or distress and at least two DSM-5 criteria within 12 months.

Which Drug Use Disorder Affected the Most People in 2024?

Marijuana use disorder affected an estimated 20.6 million people aged 12 or older, the largest drug-specific estimate in the 2024 NSDUH summary.

Did Drug Overdose Deaths Decline in 2024?

Yes. Final CDC data show that the age-adjusted overdose death rate declined 26.2%, from 31.3 deaths per 100,000 people in 2023 to 23.1 in 2024.

Do National Statistics Diagnose an Individual?

No. Population statistics describe groups, screening identifies possible risk, and a qualified clinician evaluates an individual.
