BACKGROUND AND AIMS: Stimulant drug users have a greater prevalence of risky driving behaviour. This study aimed to assess how far this association remains after adjusting for aggressiveness.
DESIGN: Cross sectional interview study assessing associations between measures of risky driving behaviours as outcomes, measures of stimulant drug use as predictors and a measure of aggressiveness as a covariate. SETTING: USA. PARTICIPANTS: Data were drawn from Wave 3 (2012-2013) of the National Epidemiological Survey on Alcohol and Related Conditions (NESARC-III) (N=36, 309 aged ≥18 years). MEASUREMENTS: Stimulant drug use, past-year DSM-5 Stimulant Use Disorder, aggression and measures of risky driving were assessed using face-to-face interviews conducted using the Alcohol Use Disorder and Associated Disabilities Interview Schedule (AUDADIS-5) and the Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM-5).
FINDINGS: Overall, 2,714 (8.3%) respondents indicated lifetime stimulant use, and 112 (0.3%) met criteria for Past Year DSM-5 Stimulant use disorder. Over 10% of ongoing stimulant users and one-third of respondents with DSM-5 stimulant use disorder reported stimulant-specific Driving Under the Influence of Drugs (DUID) in the past year (both p<0.0001). Adjusted for demographics and independent of aggression, lifetime stimulant users reported increased likelihood of driving [Adjusted odds ratio (AOR) = 3.00, 95%CI= 2.63-3.42] or speeding under the influence of drugs (AOR= 3.39 95%CI= 3.01-3.82) and licence revocation (AOR= 2.16, 95%CI= 1.87-2.50) (all p< 0.0001). Past Year DSM-5 Stimulant use disorder was associated with all outcomes (AOR= 5.48 95%CI= 2.95-10.18, AOR= 3.87 95%CI= 2.23-6.70, respectively, all p< 0.0001), except licence revocation (AOR= 1.72).
CONCLUSIONS: Stimulant use appears to be positively associated with risky driving behaviours after adjusting for aggressiveness.
