In 2010, an estimated 22.6 million Americans aged 12 or older were current (past month) illicit drug users, meaning they had used an illicit drug during the month prior to the survey interview. This estimate represents 8.9 percent of the population aged 12 or older. Illicit drugs include marijuana/hashish, cocaine (including crack), heroin, hallucinogens, inhalants, or prescription-type psychotherapeutics used nonmedically.

The rate of current illicit drug use among persons aged 12 or older in 2010 (8.9 percent) was similar to the rate in 2009 (8.7 percent), but higher than the rate in 2008 (8.0 percent).

Marijuana was the most commonly used illicit drug. In 2010, there were 17.4 million past month users. Between 2007 and 2010, the rate of use increased from 5.8 to 6.9 percent, and the number of users increased from 14.4 million to 17.4 million.
