Drugged driving: increased traffic risks involving licit and illicit substances

Area of Science:

• Drug and Alcohol Studies
• Traffic Safety Research
• Forensic Toxicology

Background:

• Driving under the influence of drugs (DUI) presents significant traffic safety hazards.
• Research has primarily focused on alcohol, illegal substances, and high-abuse potential prescription drugs.
• Understanding patterns of drug use among DUI offenders is crucial for effective interventions.

Purpose of the Study:

• To identify drug types used by convicted DUI offenders on their arrest day.
• To determine the prevalence of poly-substance use among this population.
• To explore offender characteristics linked to various drug use patterns.

Main Methods:

• Analysis of data from 6,339 individuals in Mississippi's Alcohol Safety Education Program.
• Self-reported substance use on the day of arrest.
• Statistical examination of drug prevalence and poly-substance use patterns.

Main Results:

• Alcohol was the most prevalent substance, followed by cannabis.
• Sedative medications and prescription analgesics were also frequently reported.
• A significant majority (78.4%) of poly-substance users combined alcohol with other drugs.

Conclusions:

• Cannabis is a prevalent drug used by DUI offenders, second only to alcohol.
• Combining alcohol with other drugs is common among DUI offenders, exacerbating impairment.
• Findings can inform public education, law enforcement training, and highway safety policies.
