About 6% of US Drivers Aged 16-20 Reported Driving Under the Influence of Cannabis, More Than Double the Rate for Alcohol

In a nationally representative US sample, 6.3% of drivers aged 16-20 reported driving after cannabis use, compared to 2.6% for alcohol, with nearly one in four past-year cannabis users (24.5%) reporting impaired driving.

What This Study Found

DUI-cannabis prevalence was 6.3% in the full sample and 24.5% among past-year cannabis users. DUI-alcohol was 2.6% overall and 6.1% among past-year alcohol consumers. Risk was elevated among older and male youth for both substances. More than one million young drivers per year are estimated to drive after using cannabis and/or alcohol.

Key Numbers

N=12,863 drivers ages 16-20. DUI-cannabis: 6.3% overall, 24.5% among users. DUI-alcohol: 2.6% overall, 6.1% among drinkers. Estimated 1+ million young DUI drivers per year.

How They Did This

Cross-sectional analysis of 2020-2021 NSDUH data for drivers ages 16-20 (N=12,863). Survey-adjusted prevalence estimates and logistic regression weighted for stratified cluster sampling.

Why This Research Matters

Cannabis-impaired driving among underage drivers is more than twice as prevalent as alcohol-impaired driving in this age group. This challenges the traditional focus on alcohol-impaired driving prevention among young people.

The Bigger Picture

The higher rate of cannabis DUI compared to alcohol DUI among young drivers reflects both the normalization of cannabis use and perhaps a lower perceived risk of driving while high compared to driving drunk. This perception gap may be especially dangerous.

What This Study Doesn't Tell Us

Self-reported DUI likely underestimates true prevalence. Cross-sectional design. 2020-2021 data may reflect pandemic-related changes in driving patterns. Cannot assess actual impairment level or crash risk from survey data.

Questions This Raises

  • ?Do young drivers perceive cannabis-impaired driving as less risky than alcohol-impaired driving?
  • ?Would combining cannabis DUI education with alcohol DUI prevention programs be more effective?

Frequently Asked Questions

How common is driving high among young people?

Is cannabis DUI more common than alcohol DUI among teens?

Yes. In this national sample, cannabis DUI (6.3%) was more than twice as prevalent as alcohol DUI (2.6%) among 16-20 year old drivers.
