Pot vending machines may be coming to Washington’s pot stores.They’re apparently rolling into Colorado, or at least into one Colorado shop. The Denver Post, in its “The Cannabist blog,” reported that an “automated, age-verifying, climate-controlled” vending machine is being installed inside a Colorado medical-marijuana dispensary.Washington state is considering allowing such machines in its recreational-pot shops, according to Randy Simmons, deputy director of the state Liquor Control Board, the agency implementing the state’s legal-pot law.“At first blush, it seems feasible that they could be used in a licensed retail store, but I would need more internal discussion to say yes for sure,” Simmons said.“I think it would be workable, basically the customer is simply bypassing the cash register,” Simmons continued in an email. “They can’t get access to the product unless they purchase it, it is prepackaged, and only the retailer feeds the machine. Seems like a viable option.”Expected to open in July, recreational-pot shops in Washington will not allow anyone under 21 inside. So minors using the vending machines is not a concern.
