Drug addiction can often times be hidden in plain sight, making it difficult to identify. Understanding and recognizing the signs, symptoms, risks and more is the first step in the recovery journey.
Learn about drug addiction
The term “substance abuse” refers to the misuse of legal or illicit drugs. The most commonly abused substances in the United States include alcohol, marijuana, and prescription painkillers that contain opioids. Cocaine, methamphetamine, heroin, and a variety of other drugs also contribute to the nation’s substance abuse problem.
Some people engage in substance abuse in an attempt to self-medicate. Others do so solely for recreational purposes. Regardless of the reason, substance abuse can expose you to immediate damage and long-term harm. The risks of substance abuse include physical and psychological distress, overdose, and the development of an addiction.
Drug addiction statistics
The following statistics are from the 2016 National Survey on Drug Use and Health, which was conducted by the Substance Abuse and Mental Health Services Administration (SAMHSA):
- 28.6 million Americans age 12 and above, or 10.6% of the population, used an illicit drug in the past 30 days.
- About 20.1 million people age 12 and above met the diagnostic criteria for a substance use disorder (addiction) in 2016.
- About 25% of young adults ages 18-25 engaged in illicit drug use in the past month. This is the highest rate among all age groups.
- About 11.8 million people abused opioids in 2016. This includes approximately 11.5 million people who reported misusing prescription painkillers and 948,000 people who told researchers they had used heroin.
- 16.3 million Americans age 12 and above reported heavy alcohol use in the past month. SAMHSA defines heavy alcohol use as five or more episodes of binge drinking in a 30-day period.
