Jeff Brubacher from Vancouver General Hospital published “Cannabis use as a risk factor for causing motor vehicle crashes: a prospective study.” The study has earned a great deal of press due to his finding that there was no increased risk of crash responsibility in the driver pool he studied for drivers with a blood THC level between 2 and 5 ng/ml. There was an increased risk of crash responsibility for drivers over 5 ng/ml, but … READ MORE
Colorado’s HB18-1258 that would have permitted marijuana “tasting rooms” passed the legislature but was vetoed by Governor HIckenlooper. The Governor cited concerns with increased impaired driving as a reason for his veto.

The thrust of the op-ed is that, since marijuana is unlike alcohol chemically and metabolically, an impairment-based per se limit like we have for alcohol just doesn’t work for marijuana’s THC. There is no scientific support for any THC per se limit. In particular, the 5 ng/ml THC … READ MORE
