What is the most common drug besides alcohol found in crashes involving impaired drivers?

• A. Cocaine
• B. Methamphetamine
• C. Opioids
• D. Marijuana

Answer: (D)

Marijuana is the most frequently detected non-alcohol drug in crash-involved drivers because its use is widespread and it shows up most often in post-crash testing. It impairs key driving skills such as reaction time, tracking, and lane position, and these effects are particularly noticeable when combined with alcohol, which many drivers do. While other drugs like cocaine, methamphetamine, and prescription opioids can contribute to crash risk, they appear less often in crash data than marijuana. So, marijuana stands out as the most common drug found in crashes involving impaired driving.
