> At what levels of THC concentrations is driving empirically impaired and is this measurement consistent across everyone? What evidence do you have to support that THC impairs driving? The Government of Canada has already legislated [0] that THC impairs driving and that the per-se limit is 2ng of THC per ml of blood. I'm certain this YC company had nothing to do with lobbying for that legislation and that it would have been passed with or without them. Surely if there is someone to blame for setting nonsensical limits, you should blame the government and the hysterical voters who elect them.
