Estimated Prevalence of Substance Use Dependence or Addiction in the US by Race/Ethnicity, According to NSDUH

"In 2015, approximately 20.8 million people aged 12 or older had an SUD in the past year, including 15.7 million people who had an alcohol use disorder and 7.7 million people who had an illicit drug use disorder (Figure 27). An estimated 2.7 million people aged 12 or older had both an alcohol use disorder and an illicit drug use disorder in the past year (Figure 28). Thus, among people aged 12 or older in 2015 who had an SUD in the past year, nearly 3 out of 4 had an alcohol use disorder, and about 1 out of 3 had an illicit drug use disorder. About 1 in 8 people aged 12 or older who had SUDs in the past year had both an alcohol use disorder and an illicit drug use disorder.
"Of the 7.7 million people aged 12 or older who had a past year SUD related to their use of illicit drugs, 4.0 million had a past year disorder related to their use of marijuana, and 2.0 million people had a disorder related to their misuse of prescription pain relievers (Figure 27). Smaller numbers of people in 2015 had disorders in the past year related to their use of cocaine or heroin.
"The 20.8 million people who had SUDs in 2015 (Figure 27) represent 7.8 percent of people aged 12 or older (Figure 29). This percentage of people in 2015 who had SUDs corresponds to about 1 in 13 people aged 12 or older. An estimated 1.2 million adolescents aged 12 to 17 had SUDs in 2015, which represents 5.0 percent of adolescents, or about 1 in 20 adolescents. In 2015, 5.3 million young adults aged 18 to 25 had SUDs; this number of young adults with SUDs represents 15.3 percent of young adults, or about 1 in 7 young adults. An estimated 14.2 million adults aged 26 or older in 2015 had SUDs, which represents 6.9 percent of adults aged 26 or older, or about 1 in 15 adults in this age group."
