Introduction: The National Survey on Drug Use and Health
The Substance Abuse and Mental Health Services Administration's National Survey on Drug Use and Health (NSDUH) is the primary source of national data on substance use, substance use disorders, and mental health in the United States. Conducted annually since 1971, the NSDUH surveys approximately 67,500 individuals aged twelve and older, using a nationally representative sampling design that enables precise estimates of substance use prevalence across demographic groups, geographic regions, and over time. The comprehensiveness and methodological rigor of the NSDUH make it an indispensable resource for researchers, policymakers, and clinicians seeking to understand the scope of the addiction crisis.
The most recent NSDUH results paint a complex picture of substance use in America. While some trends are encouraging, such as continued declines in cigarette smoking among youth, other indicators remain deeply concerning, including persistently high rates of opioid misuse, escalating stimulant use, and a widening treatment gap that leaves the vast majority of individuals with substance use disorders without professional help. Understanding these data is essential for identifying where clinical resources are most needed and for making the case for expanded treatment investment.
At Trust SoCal in Orange County, we track SAMHSA data carefully to ensure our programs address the most pressing clinical needs in our community. The data described in this article reflects national trends, but Orange County faces its own specific challenges related to substance use, including high rates of prescription opioid misuse and stimulant use disorders. Our clinical team at 16537 Elm Cir, Fountain Valley, CA 92708 uses this epidemiological information to continuously refine our treatment offerings.

Prevalence of Substance Use Disorders: The Scale of the Crisis
The NSDUH data reveals that substance use disorders affect a staggering proportion of the American population. An estimated 48.7 million Americans met DSM-5 criteria for a substance use disorder in the past year, representing 17.3 percent of the population aged twelve and older. This figure represents a meaningful increase from pre-pandemic estimates and reflects the substantial disruption that COVID-19 wrought on mental health and substance use patterns across the country. The pandemic accelerated several concerning trends, including increased alcohol consumption, heightened opioid overdose mortality, and reduced access to treatment services.
Alcohol use disorder remains the most prevalent specific substance use disorder, with SAMHSA estimating that 29.5 million Americans meet criteria for this condition. This substantial prevalence reflects alcohol's unique status as a legal, widely available, and socially normalized substance, factors that simultaneously increase exposure and reduce treatment-seeking due to stigma. Cannabis use disorder affects an estimated 8.9 million Americans, a figure that has grown substantially over the past decade alongside increased cannabis legalization and declining perceptions of risk. Opioid use disorder affects approximately 6.1 million Americans, with the majority of this burden attributable to illicit opioids, primarily heroin and illicitly manufactured fentanyl.
The co-occurrence of substance use disorders and other mental health conditions is documented at high rates in SAMHSA data. Approximately 21.5 million Americans had co-occurring mental illness and substance use disorders in the past year, a group that faces particularly poor outcomes without integrated treatment. SAMHSA data consistently shows that individuals with co-occurring disorders are more likely to experience serious functional impairment, require higher levels of care, and have worse treatment outcomes when their psychiatric conditions are not adequately addressed.
SAMHSA data reveals that only 13 percent of people with a substance use disorder received specialty addiction treatment in the past year, meaning approximately 42 million Americans who need treatment are not receiving it.
Substance-Specific Prevalence Statistics from SAMHSA
The following prevalence estimates from the most recent NSDUH data illustrate the relative burden of different substance use disorders across the American population.
- Alcohol Use Disorder: 29.5 million Americans (10.5% of those 12+), making it the most common substance use disorder despite being socially normalized.
- Cannabis Use Disorder: 8.9 million Americans (3.2%), with rates increasing substantially over the past decade, particularly among young adults aged 18-25 in states with recreational legalization.
- Opioid Use Disorder: 6.1 million Americans (2.2%), including both prescription opioids and heroin; overdose deaths from opioids have exceeded 80,000 annually in recent years.
- Stimulant Use Disorder: 1.9 million Americans for methamphetamine and 1.4 million for cocaine, with methamphetamine rates rising sharply in Western states including California.
- Sedative, Hypnotic, or Anxiolytic Use Disorder: Approximately 700,000 Americans, a figure that may underestimate true prevalence given high rates of benzodiazepine misuse.
The Treatment Gap: Why Most People Do Not Receive Help
Perhaps the most clinically significant finding in SAMHSA data is the persistent and enormous gap between the prevalence of substance use disorders and the proportion of affected individuals who receive treatment. Only approximately 13 percent of the 48.7 million Americans with a substance use disorder received specialty addiction treatment in the past year. This treatment gap represents one of the most significant public health failures in contemporary American medicine, as effective treatments exist but are not reaching the vast majority of those who need them.
SAMHSA data identifies several primary reasons why individuals with substance use disorders do not seek or receive treatment. The most commonly cited reason across surveys is that the individual did not perceive a need for treatment, which reflects both minimization of the problem and persistent stigma that prevents accurate self-assessment. Other frequently cited barriers include cost and lack of insurance coverage, lack of transportation or program availability, fear of stigma from employers or family members, and concerns about confidentiality.
Racial and ethnic disparities in treatment access are clearly documented in SAMHSA data. Black Americans are significantly less likely than white Americans to receive treatment for equivalent rates of substance use disorders, reflecting systemic barriers including differential access to insurance coverage, geographic concentration in underserved communities, and cultural stigma around help-seeking. Hispanic Americans also face significant treatment access barriers, including language differences, immigration-related concerns, and cultural norms. Trust SoCal is committed to reducing these disparities by providing culturally responsive, accessible care to all communities in Orange County.
SAMHSA data shows that the annual economic cost of substance use disorders in the United States exceeds 740 billion dollars, including costs related to crime, lost work productivity, and healthcare. Expanding treatment access is both a public health imperative and an economic necessity.
Emerging Trends in Substance Use: What SAMHSA Data Reveals
SAMHSA's longitudinal data enable identification of emerging trends in substance use patterns that have critical implications for treatment planning. The most alarming recent trend is the rise of polysubstance use involving fentanyl, an illicitly manufactured synthetic opioid that is now ubiquitous in the illicit drug supply. NSDUH data, combined with CDC overdose mortality statistics, reveals that fentanyl is now present in counterfeit pills sold as stimulants, sedatives, and other substances, dramatically increasing overdose risk for individuals who do not intend to use opioids.
Methamphetamine use has increased substantially in recent years, with SAMHSA data documenting rising rates of past-year methamphetamine use across demographic groups. The current methamphetamine supply in the United States is of substantially higher purity than that available in previous decades, producing more severe addiction and a higher rate of psychosis and other psychiatric complications. The absence of FDA-approved medications for stimulant use disorder makes the rising methamphetamine burden particularly challenging for treatment providers.
Youth substance use trends documented in SAMHSA data show both encouraging and concerning patterns. Rates of alcohol and cigarette use among adolescents have declined substantially over the past two decades, reflecting the success of evidence-based prevention programs. However, vaping among youth remains at historically high levels, and cannabis use rates have plateaued at elevated levels. SAMHSA data also suggests increases in prescription drug misuse among college-age young adults, including non-medical use of stimulants for academic performance.
Key Trends Shaping the Substance Use Landscape
SAMHSA data highlights several critical trends that treatment providers must address in designing and delivering effective care.
- Fentanyl Contamination: Synthetic opioids now drive the majority of overdose deaths; harm reduction strategies including fentanyl test strips and naloxone distribution are critical evidence-based responses.
- Rising Stimulant Use: Methamphetamine and cocaine use disorder rates are increasing, particularly in western states, creating urgent need for expanded behavioral treatment options.
- Polysubstance Use: SAMHSA data shows increasing rates of individuals using multiple substances simultaneously, requiring assessment and treatment protocols addressing complex presentations.
- Mental Health-Substance Use Convergence: Co-occurring rates are rising, with pandemic-related mental health deterioration contributing to increased substance use as a coping mechanism.
- Post-Pandemic Treatment Surge: Demand for addiction treatment services has increased substantially since 2020, straining treatment capacity across the country.
SAMHSA Data on Treatment Outcomes and Recovery
In addition to prevalence and treatment access data, SAMHSA collects information on recovery status and treatment outcomes that provide a more complete picture of the addiction and recovery landscape. SAMHSA's definition of recovery encompasses a process of change through which individuals improve their health and wellness, live self-directed lives, and strive to reach their full potential. This definition explicitly acknowledges that recovery is a journey rather than a destination and includes multiple pathways.
SAMHSA data on recovery prevalence reveals encouraging findings about the scope of addiction recovery in America. Surveys estimate that approximately 22.5 million Americans aged twelve or older consider themselves to be in recovery from a drug or alcohol problem, representing roughly 9 percent of the adult population. This finding directly challenges nihilistic narratives about addiction being untreatable and provides compelling evidence that recovery is achievable for a substantial proportion of individuals who struggle with substance use disorders.
Treatment outcome data collected by SAMHSA through the Treatment Episode Data Set (TEDS) provides insights into who is receiving treatment, what types of care are being utilized, and how treatment utilization patterns have changed over time. TEDS data consistently documents that opioids account for the plurality of treatment episodes nationally, reflecting the severity of the opioid crisis. SAMHSA has advocated strongly for the evidence-based shift toward outpatient and community-based care delivery.
