Nevada has broken a logjam that threatened to cut off the supply of legal recreational marijuana.

The state, which officially began selling legal marijuana on July 1, only issued its first license to actually transport the product from the farm to the store on Wednesday.

The move will give some dispensary managers relief while officials sort out a larger distribution issue.

Five states allow legal recreational marijuana sales, but Nevada limits which companies can participate in its supply chain. The rules led to worries among dispensary managers that they wouldn't be able to restock following better than expected demand during the first two weeks of legal sales.

But the first license was awarded to Blackbird Logistics Corporation, which began shipping almost immediately. A second license was issued to liquor distributor Rebel One, and the state is getting ready to issue a third.

"The dam has been broken and stuff is starting to trickle in," said Al Fasano, COO of the Las Vegas dispensary ReLeaf, who had been worried that his shelves may run dry without a shipment of new product.

Blackbird has operated primarily as a logistics and delivery company for medical marijuana, which has been legally sold in Nevada since 2014.

Medical marijuana does not carry restrictions on its supply chain under state law and anyone can transport it. Recreational marijuana, however, can be shipped only by liquor distributors.

Blackbird teamed up with liquor distributor Crooked Wine to begin transporting legal weed.

The Nevada Tax Commission voted unanimously Thursday to approve "emergency regulations" to analyze whether there are enough liquor distributors to supply the state's 47 legal dispensaries. The commission will then decide whether to let non-liquor companies be distributors.

Demand for legal marijuana has been huge in Las Vegas where tourists are lining up in triple-digit heat to get some. Dispensary managers who talked to CNNMoney said the demand was almost double what they anticipated and that they worried their stores might run out of inventory. None of the dispensaries seem to have completely run out of stock, so these state licenses might be coming in the nick of time, they said.

Blackbird CEO and co-founder Tim Conder told CNNMoney he has plans to double his 30-employee workforce by the end of the month to handle a dramatic increase in work.

Blackbird is only one company, however, and more help is likely needed to keep the burgeoning industry afloat.

The Nevada Department of Taxation, which oversees the industry, reached out earlier this year to liquor distributors and found no takers, blaming either a lack of interest or a failure to meet application requirements.

The department subsequently invited non-liquor companies to participate in the supply chain, and was promptly sued by the Independent Alcohol Distributors of Nevada, a liquor industry group.

Last month, a Carson City judge ruled in favor of the liquor distributors, giving them the exclusive right to deliver recreational weed, at least for now. The Taxation Department appealed that decision.

Kevin Benson, a lawyer representing the liquor industry in its lawsuit, blamed the Taxation Department for the holdup in issuing licenses.

"This is not the fault of the distributors," he said. "It is because the licensing process was badly delayed due to the Department's initial, erroneous, determination back in March that alcohol distributors were insufficient."

In addition to Nevada, retail sales for recreational marijuana are legal in Alaska, Oregon, Washington and Colorado. Recreational marijuana is also legal in California, Massachusetts, Maine and the District of Columbia, but there is no legal market in those places yet.

Medical marijuana is legal in 29 states, but the drug remains illegal in the eyes of the federal government.
