SEATTLE – People in Washington decided that marijuana, long derided as a dangerous drug that could lead to more harmful addictions, wasn’t so bad after all. Initiative 502, legalizing pot for adults, was easily approved in November and that sweeping change to drug policy was voted the state’s top news story of 2012 by Associated Press member editors. The other top news items of the past 12 months included another vote by Washingtonians, this one affirming gay people’s right to marry, as well as the expensive, hard-fought governor’s race, a local soldier accused of massacring civilians in Afghanistan and large, destructive wildfires in central and Eastern Washington.
