Green Dragon, one of Colorado’s largest cannabis companies, is preparing to cease operations. The company said in a notice to the state labor department last week that it plans to lay off all 59 workers at its 92,000-square-foot grow facility at 830 Wyandot St. in Denver by year end. Cory Azzalino, CEO of Eaze, a California-based cannabis delivery firm that is also Green Dragon’s parent company, told BusinessDen Friday morning that all 17 Green Dragon retail locations in Colorado will close by then too. ‘We didn’t have to file a WARN in Colorado for those,” he said, citing the employee count at each store being under a 50-worker threshold.
