OLYMPIA — Officials have processed more than 6,600 marijuana business license applications in Washington state, including 291 in Clark County, and they still have more to go.The state Liquor Control Board issued updated figures Tuesday for applications to grow, process and sell pot under Washington’s legal marijuana law, passed by voters in 2012. The total so far: 6,619.Some 2,666 of those are growing license applications, and 1,918 are processing applications. In Clark County, there are 36 applications to grow pot and 99 have applied to process it so farThe board at least initially is limiting the number of stores to 334 statewide, including 15 in Clark County. There have been 2,035 retail applications received by the state, with 156 retail applicants from Clark County. This means there could be lotteries to decide which applicants will become licensed stores, where adults older than 21 will be able to buy up to an ounce of marijuana under Initiative 502.A few potential Clark County pot businesses submitted multiple applications to sell marijuana from more than one site.Board spokesman Mikhail Carpenter says some incomplete applications are still being processed by the state and that officials are working with those applicants.“The ones we have left are people who have not supplied all of the information necessary,” he said.Carpenter said the board expects to begin issuing licenses in late February or March, at which point it will be up to the newly legalized industry to provide supply for the private pot market and open retail stores.
