SEATTLE - Washington voters have made their state the first in the nation to legalize recreational pot use, setting up a showdown with a federal government that backs the drug's prohibition.
The outcomes of related measures in Colorado and Oregon were uncertain.
The Washington measure sets up a system of state-licensed marijuana growers, processors and retail stores, where adults over 21 can buy up to an ounce. It also establishes a standard blood test limit for driving under the influence.
Estimates have showed pot taxes could bring in hundreds of millions of dollars a year, but the sales won't start until state officials make rules to govern the legal weed industry.
