Agreed. I think the value of results like this is to challenge selection biases. I have family in Colorado where marijuana was recently legalized, an action I support despite never smoking it nor having desire to. They're worried about the legalization resulting in everyone driving high, and they constantly cite 1 incident where someone rear-ended a cop while high. It's illogical to take anything from a single incident simply because it was relevant enough to make headlines and ignore all the other different incidents that don't make headlines because there's nothing novel about them.
