More drivers testing positive for pot: Washington State PatrolBy Jonathan Kaminsky OLYMPIA, Washington (Reuters) - Significantly more drivers pulled over by police in Washington state are testing positive for marijuana since legalization of the drug's recreational use took effect in January, according to figures released this week by the Washington State Patrol. The increase comes despite the fact that recreational-use pot stores will not open in Washington state until next year. Washington State Patrol spokesman Bob Calkins said the findings, while preliminary, indicate more people may be driving impaired than was the case before Washington and Colorado in January became the first states to legalize recreational use of the drug. Some 20 states and the District of Columbia allow medical marijuana use.
