Alcohol and Marijuana Use Patterns Associated with Unsafe Driving Among U.S. High School Seniors: High use Frequency, Concurrent Use, and Simultaneous Use

This article expands on the knowledge of individual risk factors associated with unsafe driving among United States (US) teens. The efforts to educate US high school students (especially substance users), parents, and individuals involved in prevention programming and driver's education about the increased risks associated with various forms of drug use status are presented. The article will examine noncausal associations between high school seniors' alcohol and marijuana use status and rates of self-reported unsafe driving over the past 12 months. Data from 72,053 students collected through annual surveys of nationally representative cross-sectional samples of US 12th-grade students from 1976 to 2011 are analyzed. Two aspects of past-12-month alcohol and marijuana use were examined using frequency and status as a nonuser, single substance user, concurrent user, or simultaneous user. Measures of past-12-month unsafe driving included any tickets/warnings or accidents, as well as tickets/warnings or accidents following alcohol or marijuana use. Analyses explored whether an individual's substance use frequency and simultaneous use status had differential associations with their rate of unsafe driving and higher substance use frequency (primarily alcohol use frequency) was significantly and positively associated with unsafe driving. The rate of engaging in any unsafe driving was also significantly and positively associated with simultaneous use status, with the highest rate associated with simultaneous use, followed by concurrent use, followed by alcohol use alone. Individuals who reported simultaneous use most or every time they used marijuana had the highest likelihood of reporting unsafe driving.
