Federal Study: Marijuana Use Doesn't Increase Auto Crash Rates

An anonymous reader writes: After the legalization of marijuana in multiple states around the U.S., many are worried about a corresponding uptick in car crashes as people drive while under the influence of pot. But according to a new federal study (PDF) commissioned by the National Highway Traffic Safety Administration, those fears seem unfounded. They report that after adjusting for other factors (people who tend to drive after using marijuana also tend to be more crash-prone in general), there was no statistically significant increase in crash rates by drivers who tested positive for the drug. It's still a bad idea to drive high, but driving drunk is far, far worse: "One substance was shown to have a major influence on crashes: alcohol. The study confirmed the enormous danger of drinking and driving, even after age and sex adjustment: drivers with a 0.05% blood-alcohol level were found to be twice as likely to be in a crash. For a person weighing 180 to 190 pounds, that could be a single can of beer, glass of wine, or shot of liquor. At 0.08% (two drinks), the likelihood is quadrupled, and at .20% (four drinks or more), the risk is higher by 23 times."

Drunk drivers run through stop signs.
High drivers wait for the stop signs to turn green.

Any time someone responds to a study with the general statement "They are wrong, I have an anecdote to prove it!" should be tagged and forever prohibited from participating in discussions or weighing in on decisions on the topic.

I knew a guy once who agreed completely with you. I do too.
