SEATTLE — Pete O’Neil saw Washington’s legalization of marijuana in 2012 as a path to retirement, or at least to his kids’ college tuition.

He’s paid tens of thousands of dollars in rent on possible locations for a pot-shop chain, hired lawyers and picked out flooring. But now the nation’s second legal recreational marijuana industry is about to start without him.

O’Neil struck out in Washington’s lottery for coveted pot-shop licenses. He has unsuccessfully tried to buy companies that scored a lucky number. In frustration, he’s turning what would have been his Seattle retail store into a medical marijuana dispensary.

“Our company is bleeding money, and I haven’t sold a single joint,” O’Neil says.

As Washington plows toward the legal pot promised land, it’s finding that getting the cannabis market off the ground has been even tougher than anyone imagined.

Among the frustrated are growers who have been waiting months for permission to start raising their bar-coded plants; advocates who wish more public health messaging had been done by now; and would-be pot vendors like O’Neil who say bad luck, minor oversights on their applications, or errors by state officials have torpedoed otherwise promising efforts.

Washington’s Liquor Control Board expects to issue the first 15 to 20 marijuana retail licenses July 7, months later than first expected, but it’s not clear how many of those shops are ready to open. Board staff said last week only one shop in Seattle is prepared for its final inspection.

Randy Simmons, the board’s legal pot project manager, predicts “a bumpy road,” with an initial shortage of stores and marijuana alike. Many businesses that got lucky in the pot-shop lottery in April have since been disqualified, such as by being too close to schools or playgrounds. Others haven’t finished building or made deals to buy pot from licensed growers.

“This is a gold-rush mentality and everybody wants to get rich,” Simmons says. “Some people just don’t have an idea what they’re doing — no clue at all. It slows down the process.”

Pot shortages are certain. More than 2,600 people applied last fall to grow marijuana, but those applications are being reviewed glacially by the board’s 18 swamped licensing investigators. Only about 80 growers have been approved, and some won’t harvest by early July. Hundreds of applicants haven’t even been assigned an investigator.

Prices could run more than $25 a gram for the heavily taxed pot — about twice what the state’s unregulated medical dispensaries charge — until more growers are licensed, Simmons says.

There will be no edibles available. People who want to make brownies, cookies or other pot-infused treats must have their kitchens inspected by the state. Of the two tested so far, one failed — it didn’t even have a hand-washing sink. The report on the other hasn’t been completed.
