Three nurseries rejected by health officials for medical marijuana licenses are challenging the licenses granted to Florida’s first “dispensing organizations,” with possibly more appeals on the horizon.

In a challenge filed Friday, Gainesville-based San Felasco Nurseries argued that the grower was erroneously disqualified because of issues surrounding a background screening of its research and development director. The nursery also alleges that the winner of the license for the state’s Northeast region, Chestnut Hill Tree Farm, is ineligible to be one of the five dispensing organizations, which will grow, process and distribute non-euphoric marijuana legalized last year.
