SEATTLE — 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, even though the patrol had fewer troopers on the road and there was no overall rise in intoxicated driving arrests.
