> Driving while high should definitely be banned As there's no valid means of determining "while high", this is simply not a rational thing to attempt to do. Additionally, there's no data supporting that driving while high is actually a problem that needs solving, specifically that people don't know they're too high and drive anyway. You should first prove something is a problem before attempting to outlaw it.
