Getting behind the wheel while stoned is indeed dangerous but not nearly as much as previously thought, according to a study by two Norwegian researchers.
Published in the journal Addiction, the study investigated how likely drivers who had been using cannabis were to get into a car accident. The researchers looked at 20 studies and two meta-analyses published between 1982 and 2015.
The study reportedly has a more unusual conclusion than previous research because it corrected for perceived methodological flaws of past studies. These methodological inaccuracies mean previous studies overestimated the risk of marijuana use while driving, according to the paper.
