Substance use disorders (SUDs) are the most common psychological disorders in the United States. They involve the misuse of alcohol, prescription medications, or illicit drugs, leading to significant impairment in daily life. According to the National Institute on Drug Abuse (NIDA) and the Substance Abuse and Mental Health Services Administration (SAMHSA), millions of Americans struggle with substance use disorders each year.
Prevalence of Substance Use Disorders
In the U.S., alcohol use disorder (AUD) is particularly widespread. The National Survey on Drug Use and Health (NSDUH) reports that nearly 29 million Americans aged 12 and older had an alcohol use disorder in recent years. Additionally, opioid use disorder (OUD) and stimulant abuse (such as cocaine and methamphetamine) are major concerns.
Factors Contributing to Substance Use Disorders
Several factors contribute to the high prevalence of substance use disorders, including:
- Genetics – A family history of addiction increases the risk.
- Environmental influences – Peer pressure, trauma, and stress can lead to substance abuse.
- Mental health conditions – Anxiety, depression, and PTSD often co-occur with substance use disorders.
Impact on Society
Substance use disorders contribute to:
- Increased healthcare costs
- Higher crime rates
- Workplace absenteeism
- Strained relationships and family conflicts
Comparison with Other Disorders
While mood disorders (such as depression and bipolar disorder) and personality disorders are common, substance use disorders affect a broader population and have a significant impact on public health. Schizophrenia, though severe, is much less common.
Thus, substance use disorders are the most prevalent psychological disorders in the U.S.
