Associations between driving under the influence or riding with an impaired driver and future substance use among adolescents.

ABSTRACT: Objective: Risky driving behaviors among adolescents, such as riding with a drinking or impaired driver (RWID) or driving while under the influence (DUI) of alcohol or drugs, are significant public health concerns. Few studies have examined associations of RWID and DUI with future substance use and problems after controlling for baseline substance use. Given that the DUI/RWDD event may be a teachable moment to prevent future consequences (e.g., when injured or arrested), it is important to understand how this risk behavior relates to subsequent use and problems. This study therefore examined characteristics of adolescents who reported DUI and RWID and assessed their risk of future alcohol and marijuana use and consequences 6 months later. Methods: Participants were 668 adolescents aged 12 to 18 (inclusive) recruited at 1 of 4 primary care clinics in Pittsburgh and Los Angeles as part of a larger randomized controlled trial. They completed surveys about their health behaviors at baseline and 6 months after baseline. We examined baseline characteristics of adolescents who reported DUI and RWID and then assessed whether past-year DUI and RWID at baseline were associated with alcohol and marijuana use and consequences 6 months after baseline. Results: Fifty-eight percent of participants were female, 56% were Hispanic, 23% were Black, 14% were White, 7% were multiethnic or other, and the average age was 16 years (SD?=?1.9). At baseline, participants who reported RWID or DUI were more likely to be older, report past-year use of alcohol and marijuana, and more likely to have an alcohol use disorder or cannabis use disorder versus those who did not report RWID or DUI, respectively. At 6-month follow-up and after controlling for baseline demographics and baseline alcohol use, RWID was associated with more frequent drinking episodes in the past 3 months and greater number of drinks in the past month when they drank heavily. DUI at baseline was associated with more frequent heavy drinking episodes and alcohol and marijuana consequences 6 months later. Conclusions: RWID and DUI are significantly associated with greater alcohol and marijuana use over time. This study highlights that teens may be at higher risk for problem substance use in the future even if they ride with someone who is impaired. Prevention and intervention efforts for adolescents need to address both driving under the influence and riding with an impaired driver to prevent downstream consequences.

Project description:AimThe main objective of this study was to evaluate the effects of the COVID-19 pandemic on the pattern of alcohol use in drivers.Materialsand methods. At the National Institute of Legal Medicine from Bucharest, we performed a retrospective study on toxicology reports between January 1st, 2019 and December 31st, 2020. Breath alcohol concentration (BrAC) was tested using Dräger breathalyzers by police units at the scene, and blood alcohol concentration (BAC) was evaluated using headspace gas chromatography. Most drivers gave two blood samples, separated by a one-hour interval, case in which they could request a retrograde extrapolation of the BAC at the time when they were stopped in traffic.ResultsThe distribution of the number of cases depending on the month showed a sharp decline in the first six months of the lockdown, with a slow upward trend afterward. Mean overall values for BrAC were 0.49 +/- 0.40 mg/L, for 1st sample BAC - 1.15 +/- 0.99 g/L and for 2nd sample BAC - 1.29 +/- 0.81 g/L. Mean values obtained for BrAC were 0.48 +/- 0.39 mg/L before the pandemic and 0.52 +/- 0.43 mg/L during the pandemic. The increase was similar in absolute numbers in both male and female drivers (0.03 versus 0.04 mg/L respectively for BrAC and 0.02 g/L for both genders for 1st sample BAC). However, the percentage increase was significantly higher in women. There were 253 cases in which BrAC had values between 0.01 and 0.05, of which 138 occurred before the pandemic and 115 during the pandemic, the increase being highly statistically significant. The percentage of drivers with BAC levels below and above 0.8 g/L (the threshold value for which DUI is a felony in Romania) were similar before and during the pandemic.ConclusionsDuring the lockdown, the number of alcohol tests in traffic has decreased significantly. This reduction was not associated with statistically significant changes in BrAC or BAC. We have seen a substantial increase in the number of minimally elevated BrAC and negative BAC cases, changes that could be caused by an increased use of alcohol-based hand sanitizers.

Project description:AimsMedical marijuana law (MML) enactment in the United States has been associated with increased cannabis use but lower traffic fatality rates. We assessed the possible association of MML and individual-level driving under the influence of cannabis (DUIC) and also under the influence of alcohol (DUIA).Design and settingThree cross-sectional U.S. adult surveys: The National Longitudinal Alcohol Epidemiologic Survey (NLAES; 1991-1992), the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC; 2001-2002), and the NESARC-III (2012-2013).ParticipantsThe total n was 118 497: 41 764, 41 184, and 35 549 from NLAES, NESARC, and NESARC-III, respectively.MeasurementsAcross the three surveys, similar questions in the Alcohol Use Disorder and Associated Disabilities Interview Schedule assessed DUIC and DUIA. Ever-MML states enacted MML between 1991-1992 and 2012-2013 (overall period). Early-MML states enacted MML between 1991-1992 and 2001-2002 (early period). Late-MML states enacted MML between 2001-2002 and 2012-2013 (late period). MML effects on change in DUIC and DUIA prevalence were estimated using a difference-in-differences specification to compare changes in MML and other states.FindingsFrom 1991-1992 to 2012-2013, DUIC prevalence nearly doubled (from 1.02% to 1.92%), increasing more in states that enacted MML than other states (difference-in-differences [DiD] = 0.59%; 95% CI = 0.06%-1.12%). Most change in DUIC prevalence occurred between 2001-2002 and 2012-2013. DUIC prevalence increased more in states that enacted MML 2001-2002 to 2012-2013 than in never-MML states (DiD = 0.77%; 95% CI = -0.05%-1.59%), and in two early-MML states, California (DiD = 0.82; 95% CI = 0.06-1.59) and Colorado (DiD = 1.32; 95% CI = 0.11-2.53). In contrast, DUIA prevalence appeared unrelated to MML enactment.ConclusionsMedical marijuana law enactment in US states appears to have been associated with increased prevalence of driving under the influence of cannabis, but not alcohol.
