What effect do drugs have on people’s driving abilities? | Shapiro, Washburn & Sharp
  • Cocaine and Meth: These drugs often lead to reckless and/or aggressive driving behaviors.
  • Marijuana: A driver’s cognitive functions, perception of distance, coordination, and reaction time can be affected. 
  • Opioids: These drugs include prescription painkillers and illicit substances, such as heroin. Opioids can cause a driver to become drowsy and experience memory loss and impairment to thinking and judgment.
