Washington Attorney General Bob Ferguson visited the Yakima Valley Wednesday, talking with city and county officials and meeting with local law enforcement about the state's recent legalization of recreational marijuana.

Ferguson says the new pot law is creating some concerns, since it goes against federal law.

As the attorney for the state of Washington, my job is defend the will of voters who passed that initiative. But of course it raises all kinds of legal issues that directly impact law enforcement, so I want to make sure I’m talking to them about that.

It was Ferguson's legal opinion that gave the city of Yakima and other cities in the state the legal right to ban marijuana sales.

Ferguson’s opinion has yet to be adjudicated by the courts. He assumes his opinion will be upheld based on language in the original law.
