Estimated Number of Persons in the US with a Substance Use Disorder
"NSDUH’s overall estimates of SUD [Substance Use Disorder] include people who met the DSM-IV criteria for either dependence or abuse for alcohol or illicit drugs. In 2018, approximately 20.3 million people aged 12 or older had an SUD in the past year, including 14.8 million who had an alcohol use disorder and 8.1 million who had an illicit drug use disorder (Figure 42). Among the 8.1 million people who had an illicit drug use disorder, the most common disorders were for marijuana (4.4 million) and misuse of prescription pain relievers (1.7 million).
"The estimated 14.8 million people aged 12 or older in 2018 who had an alcohol use disorder in the past year correspond to nearly 3 out of 4 people who had an SUD (73.1 percent) (Figure 43).23 The 8.1 million people who had an illicit drug use disorder correspond to about 2 out of 5 people who had an SUD (40.0 percent). An estimated 2.7 million people had both an alcohol use disorder and an illicit drug use disorder in the past year, or about 1 in 8 people who had a past year SUD (13.1 percent).
"In 2018, the 20.3 million people with a past year SUD correspond to 7.4 percent of people aged 12 or older (Figure 44). This percentage of people who had an SUD corresponds to about 1 in 14 people aged 12 or older. The percentage of the population in 2018 with an SUD was similar to the percentages in 2015 to 2017."
