Nevada's medical marijuana dispensaries have stockpiled one to two months worth of pot sales, Commission Chairman Steve Sisolak said Thursday, in preparation for the start of legal recreational sales at 12:01 a.m. Saturday.

So the Nevada Dispensary Association, in conjunction with local law enforcement, is working with the Las Vegas Valley's 37 dispensaries permitted to sell recreational marijuana to increase safety measures at those locations.

"We've been very fortunate in Nevada. We haven't seen many serious security issues thus far," said Andrew Jolley, Nevada Dispensary Association president. "However, we are very vigilant and very concerned about public safety and our employees' safety."

Association officials joined Sisolak and Sen. Tick Segerblom, D-Las Vegas, at a press conference to emphasize their hope that opening legal recreational sales would kill illegal marijuana dealing.

"Our goal as an industry is to bring it out of the black market into a safe, tested, regulated market in the most professional way we can," Jolley said, adding that it could take time to realize that goal.
