Colorado, which legalized medical marijuana in 2000, has seen increased numbers of DUIC cases and is considering a 5-ng/mL blood THC per se law.
DUIC is more common among people who also drive drunk (70).
Drunk driving (with or without cannabis) produced a higher single-vehicle accident incidence (62%) than did DUIC (34%).
Regular smokers who had previously DUIC emphasized that publicity campaigns would not deter them from future DUIC (74).
Our study found that men with self-reported DUIC
tend to be associated with an increased risk of being involved in a car accident," said lead author Isabelle Richer, a PhD candidate at the Universite de Montreal's Department of Psychology
