(Olympia, WA)  --  The first legal sales of recreational marijuana in Washington are set to begin tomorrow after the state issues the first wave of retail licenses today.  The "Seattle Times" reports growers and processors are racing to have their product packaged and ready to be sold.  After the state Liquor Control Board notifies the first newly-licensed retailers by email, the retail outlets will be entered into the computer system that will track the entire process from seedlings to consumer sales.  Pot supply is expected to be limited initially, as many licensed growers haven't yet harvested their crops.
