Nearly 22 million Americans aged 12 and older used illegal drugs in 2009, a rise of 9 percent from 2008, the survey conducted by the Substance Abuse and Mental Health Services Administration (SAMHSA) found.
Some 7 million Americans older than 12 took prescription drugs for nonmedical reasons. The bulk of the abuse of prescription medications involved painkillers, which some 5.3 million Americans used off-label last year — a rise of 20 percent from 2002.
Among teens, the rate of nonmedical prescription painkiller use rose 17 percent year on the year, with most youngsters saying they got the meds from friends, family, or an unsecured medicine cabinet.
The rise in the use of illegal drugs was driven in large part by an increase in the use of marijuana, which 77 percent of the survey respondents said they had used in the past month.
Among teens, marijuana use rose 9 percent in 2009, partly because “discussions of legalization, so-called medical marijuana, and a proliferation of pro-drug messages” have left America’s youth “misinformed about a drug whose potency has tripled in the past 20 years,” SAMHSA said.
Sixty percent more Americans used methamphetamine in 2009 versus 2008, and three-quarters of a million used ecstasy in 2009, the highest number of users since 2002.
“Today’s findings are disappointing but not surprising, because eroding attitudes and perceptions of harm about drug use over the past two years have served as warning signs for what we see today,” said Gil Kerlikowske, director of the Office of National Drug Control Policy.
The economic slump in the United States has also played a role in pushing up the numbers of Americans who take drugs, said SAMHSA administrator Pamela Hyde.
“There is a relationship between economic issues and substance abuse,” she said.
The rate of drug abuse among the unemployed was double that of Americans with full-time jobs — 17 percent versus 8 percent.
On a brighter note, cocaine use among 18-25 year olds has fallen by 18 percent since 2007.
