Abstract

Background: Most recent research on adolescent drug use has focused on alcohol, tobacco, and marijuana. Less is known about the recent epidemiology of adolescent cocaine use, which has serious health consequences.

Purpose: To describe recent trends in cocaine use by U.S. high school students, and identify differences in lifetime and repeated use across sex and racial/ethnic groups.

Methods: We used data from the national Youth Risk Behavior Surveys (YRBS) from 1999 to 2015. We estimated the prevalence of lifetime cocaine use (LCU) and repeated lifetime cocaine use (RLCU) across years by race/ethnicity and sex and tested for linear and quadratic trends.

Results: The prevalence of LCU decreased from 1999 to 2015 (9.54%-5.19%). RLCU also decreased (5.13%-2.84%). Despite the overall decline, LCU and RLCU both rose between 2009-2015 (LCU:2.78%-5.19%, RLCU:1.58%-2.84%). Boys had higher rates of LCU and RLCU than girls (LCU:6.42% vs 4.65%; RLCU:3.69% vs 2.18%). American Indian/Alaskan Native, Native Hawaiian/Pacific Islander, and Hispanic adolescents had the highest overall prevalence of LCU. Black adolescents' LCU patterns differed from other racial/ethnic groups. The prevalence of LCU among Black boys increased over time, while the prevalence for Black girls remained consistently low.

Conclusions: Adolescent cocaine use is less common today than in the 1990s. However, rates of adolescent cocaine use have risen across all racial/ethnic groups in the past few years. Public health efforts should address at risk groups with particularly high or rising rates of cocaine use.

Keywords: Adolescents; Cocaine; Race/ethnicity; Sex differences.
