In "the first large-scale [crash risk] study in the United States to include drugs other than alcohol," NHTSA found that, once the data were adjusted for confounding variables, cannabis consumption was not associated with an increased probability of getting into an accident. Further adjusting for alcohol consumption made the crash risk of cannabis consumers equal to that of drivers who tested negative for alcohol and all other drugs. In other words, the study provides no evidence that marijuana use increases crash risk. Furthermore, the authors note, that result is similar to what the best-designed previous studies have found: a small or nonexistent increase in crash risk.
