That makes it the second most common form of illegal drug use in the U.S. after marijuana, according to Doctor Richard Miech, lead author of the study. "Prescription drug use is the next big epidemic," Miech said. "Everyone in this field has recognized that there is a big increase in the abuse of nonmedical analgesics but our study shows that it is accelerating among today's generation of adolescents."
It drew on data from the National Survey on Drug Use and Health, a series of annual, nationally representative, cross-sectional surveys of U.S. drug use. The analysis used data from 1985 through 2009.
According to Miech, the prevalence of prescription pain medication abuse among the current generation of youth is "higher than any generation ever measured." This finding was present among subgroups of men, women, non-Hispanic whites, non-Hispanic blacks and Hispanics.
"The increasing availability of analgesics in the general population is well documented, as the total number of hydrocodone and oxycodone products prescribed legally in the U.S. increased more than fourfold from about 40 million in 1991 to nearly 180 million in 2007," the study said. "Higher prevalence of analgesics makes first-time NAU among contemporary youth easier than in the past because more homes have prescription analgesics in their medicine cabinets."
Miech said parents often model drug use behavior for their children. "Youth who observe their parents taking analgesics as prescribed may come to the conclusion that any use of these drugs is OK and safe," he added.
Yet the consequences are often severe. Miech said there are now more deaths due to accidental overdoses of these drugs than deaths due to overdoses of cocaine and heroin combined. Most people who abuse prescription pain relievers report that they obtained them from family or friends.
According to the study:
• Nonmedical analgesic use accounted for an increase in emergency room visits of 129 percent between 2004 and 2009.
• Between 1997 and 2007, NAU accounted for more than a 500 percent increase in the number of Americans seeking treatment for prescription opioid dependency.
• Prescription drug abuse led to a threefold increase in unintentional overdose mortality from the 1990s to 2007.
