Misconceptions about Cannabis Use and Driving

New MADD survey details public attitude on marijuana and its influence on traffic safety.

Among the findings of a new Mothers Against Drunk Driving (MADD) survey:

  • One in eight U.S. adults admits to having driven under the influence of marijuana.
  • 76% of the American public believe incidents of driving after consuming marijuana will increase.
  • 27% recall a friend or family member driving within two hours of consuming alcohol sometime during the past three months.
  • 26% think that driving after recent consumption of marijuana is “not too concerning” or “not at all concerning.”
  • 31% of parents and grandparents report discussing the consequences of driving under the influence of alcohol “often." While 43% of parents and grandparents surveyed reported “never” broaching the subject of driving high with the next generation.
  • There is uncertainty whether it is legal to drive impaired by marijuana:
    • 40% view this as a serious crime,
    • 27% say it is only a minor traffic offense,
    • 4% think it is legal, and 27% are unsure.
    • 41% are unsure or incorrectly believe that people who regularly use marijuana are generally not impaired, making it safe to drive.

The cannabis survey was funded by State Farm® and General Motors. It measured the American public’s attitudes and knowledge about the impact of marijuana on traffic safety. The report's publication coincides with the 40th Anniversary of MADD's founding on Sept. 5.
