(Newser) – Smoking marijuana three hours or less before getting behind the wheel nearly doubles your chance of a major car crash, a study suggests. It's the first study to look at the link between cannabis and crash risk, the Canadian researchers believe. They examined study data for more than 49,000 collision victims, limiting their research to crashes that didn't involve alcohol, CBC reports. "The level of impairment might not be as severe as alcohol intoxication, but it's there and it does require a public health response," says an expert.

"it does require a public health response, says an expert." What response would that be? OFFICER: are you high? DRIVER: no i have allergies? stalemate - driver wins

It's okay because your only going 5mph when you crash.

It is entirely plausible that marijuana use leads to a big risk increase for collisions. But the problem is that this research is correlational and doesn't take into account pre-existing differences between people who smoke and drive and those who don't.
