Research has found mixed results when comparing the extent of substance use among Hispanic youths with use among non-Hispanic youths. The National Survey on Drug Use and Health (NSDUH) asks persons aged 12 or older about their use of illicit drugs and alcohol, including binge alcohol use, in the past month. Binge alcohol use is defined as drinking five or more drinks on the same occasion (i.e., at the same time or within a couple of hours of each other) on at least 1 day in the past 30 days. NSDUH defines illicit drugs to include marijuana/hashish, cocaine (including crack), inhalants, hallucinogens, heroin, or prescription-type drugs used nonmedically. This report examines the prevalence of alcohol and illicit drug use among Hispanic youths aged 12 to 17. All findings presented in this report are annual averages based on combined 2002 and 2003 NSDUH data.
