Voters initially approved medical cannabis access by passing a statewide initiative in November 2016.
Under the law, qualified patients may obtain both herbal preparations of cannabis and infused cannabis products from state-licensed dispensaries.
Products must be derived from plants harvested by one of five state-licensed cultivators. To date, only one cultivator is operational.
Two additional cultivators are expecting to harvest their initial crops this summer.
Nearly 12,000 patients are licensed in the state to participate in the medical cannabis access program.
Arkansas is one of 33 states that permits medical cannabis access.
