Cocaine and methamphetamine use in the U.S. fell significantly in 2007, but abuse of prescription drugs increased fairly dramatically.
The 2007 National Survey on Drug Use and Health, which included about 67,500 Americans, found that between 2006 to 2007, cocaine use among adults ages 18-25 decreased 23 percent. Methamphetamine use fell by a third.
However, the abuse of prescription pain relievers by young adults rose 12 percent.
