Why young people ride with cannabis-impaired drivers and what changes their minds

Young people cited trust in the driver and routine driving contexts as reasons for riding with cannabis-impaired drivers, while legal concerns and growing safety awareness acted as deterrents.

What This Study Found

Among 105 young adults from a national cohort study, two themes facilitated riding with cannabis-impaired drivers: familiarity with driving context and trust in the driver. Legal concerns deterred it during high school, while safety concerns emerged in young adulthood.

Key Numbers

105 participants interviewed; 4 trajectory classes (Abstainer, Escalator, Decliner, Persister); interviews conducted March-September 2020

How They Did This

Qualitative study using in-depth semi-structured Zoom interviews with 105 participants from the NEXT Generation Health Study, a 7-year national cohort. Participants were purposively selected from four previously derived RWI/DWI trajectory classes.

Why This Research Matters

Most cannabis-impaired driving research focuses on the driver. This study examines the often-overlooked passenger perspective, revealing that riding with impaired drivers happens during routine daytime activities rather than just late-night party scenarios.

The Bigger Picture

Prevention programs targeting cannabis-impaired driving may need to address passengers as well as drivers, and interventions may need to account for the everyday, normalized contexts in which these rides occur.

What This Study Doesn't Tell Us

Qualitative design limits generalizability. Interviews conducted during COVID-19 may have affected recall or current driving patterns. Self-reported data subject to social desirability bias.

Questions This Raises

  • ?How do passenger decisions about riding with impaired drivers differ by substance type?
  • ?Would targeted passenger-focused interventions reduce cannabis-impaired driving exposure?

Frequently Asked Questions

Why do young people ride with cannabis-impaired drivers?

Participants cited trust in the driver and familiar, routine driving contexts as the main facilitators. Many rides happened during daytime hours for everyday activities.

What discourages riding with impaired drivers?

In high school, legal concerns were the primary deterrent. Safety concerns emerged later, during young adulthood.
