SEATTLE – After a year of requests, the U.S. Justice Department said Thursday it is giving Washington state access to an FBI database so it can conduct nationwide background checks on people who apply to run legal marijuana businesses.

In a statement provided to the Associated Press, the department said allowing the checks is consistent with its priorities in letting legal marijuana experiments in Washington and Colorado move forward, including keeping people with troublesome criminal histories out of the industry.

Washington state officials started asking last April for permission to run the checks.

Without explanation, the federal agency declined to respond, even though it had allowed similar checks on medical marijuana licensees in Colorado. Washington eventually started issuing licenses without the nationwide background checks.

The discrepancy highlighted the difficulty the feds face as they allow the states to experiment with regulating a drug that’s long been illegal under federal law.

The Obama administration has said it wants the states to make sure pot revenue doesn’t go to organized crime and that state marijuana industries don’t become a cover for the trafficking of other illegal drugs. At the same time, federal authorities don’t want to actually help the states violate federal law.

Responding to an inquiry on the topic last month, the DOJ said only that it was reviewing its background check policy “to ensure a consistent national approach.”

The DOJ’s statement Thursday emphasized that while the FBI maintains the database, states that want to license medical or recreational marijuana operations will be doing the checks themselves.

It also stressed that the nationwide background checks don’t give the businesses or the states that regulate them a free pass: They’re still expected to meet eight federal law enforcement priorities the DOJ outlined in a memo last summer.

Jaime Smith, a spokeswoman for Gov. Jay Inslee, said in an email that the decision was “certainly helpful in our efforts to move forward and establish a strong regulatory framework.”

Alison Holcomb, a Seattle lawyer who drafted Washington’s pot law, called the change a relief.

“It’s an issue of consistency,” she said. “The DOJ set forth a specific set of goals it expected Washington to meet, and the refusal to perform nationwide background checks appeared to be an obstacle to allowing the state to meet those goals.”

The state’s Liquor Control Board said Thursday it will conduct nationwide background checks on people who have already received licenses as well as those whose applications are still being processed.

In Washington, officials use a point system to determine whether someone’s criminal history is too concerning to grant a license to grow, process or sell marijuana under the state law passed by voters in 2012. A felony within the past 10 years normally disqualifies an applicant, as does being under federal or state supervision for a felony conviction.

In the absence of national background checks, officials have relied on the Washington State Patrol to find any in-state arrests or convictions.

Applicants are required to disclose their entire criminal history; omissions are punishable by license rejection.
