More drivers tested positive for marijuana in Washington in 2013 - the first full year after the state legalized pot - but officials so far say there's been no obvious, corresponding jump in car accidents. The Washington State Patrol says 1,362 drivers tested positive for having active marijuana in their system - a jump of just under 25 percent from the year before.
Of those, 720 had levels high enough to lead to an automatic drugged driving conviction under the state's legal pot law. Nevertheless, a preliminary tally counts 99,690 crashes reported to law enforcement in 2013, an increase of just 72 from the year before. Of those, 443 were fatal - about the same as the previous two years.
