The Washington State Patrol says outdoor marijuana growing operations continued to decline in 2013.
The Yakima Herald-Republic reports eradication teams pulled about 39,000 plants this year across the state. That compares with the peak of 609,000 plants in 2009. In 2012, 216,000 plants were eradicated.
State Patrol Chief John Batiste says the goal of authorities is to keep Washington from being a source of marijuana. He says the illegal drug trade attracts violence.
In 2012, Washington state voters legalized the recreational use of marijuana, and state-regulated stores are expected to open sometime next year.
