Estimated Prevalence of Non-Medical Use of Pain Relievers in the US, 2014

"Overall estimates of current nonmedical use of prescription psychotherapeutic drugs among the population aged 12 or older that were described previously have largely been driven by the nonmedical use of prescription pain relievers. In 2014, about two thirds of the current nonmedical users of psychotherapeutic drugs who were aged 12 or older reported current nonmedical use of pain relievers (Figure 5).
"The estimated 4.3 million people aged 12 or older in 2014 who were current nonmedical users of pain relievers represent 1.6 percent of the population aged 12 or older (Figures 5 and 6). The percentage of people aged 12 or older who were current nonmedical users of pain relievers in 2014 was lower than the percentages in most years from 2002 to 2012, but it was similar to the percentage in 2013."
