OLYMPIA, Wash. -

Washington state will hold lotteries this month for its coveted legal marijuana retail licenses.

The state Liquor Control Board on Wednesday adopted a plan for the lotteries, which will be held for any cities or counties where there are more pot-shop applicants than licenses allotted.

The board says the lotteries, to be held April 21-25, will be double-blind to ensure security, and the board itself will play no role in picking winners. Instead, a random order will be generated by Washington State University, with the assistance of the accounting firm for the Washington Lottery.

The winners will be given priority in the issuance of licenses, but they'll still have to pass financial investigations and meet other requirements before the board actually issues any licenses. The first retail sales are expected to begin in July.
