Federal agriculture officials have approved hemp production plans last week for one additional state and one American Indian Tribe.
However, lawmakers have recently ramped up pressure on the USDA, asking the agency to delay implementation of the final hemp production rules, with the 2014 pilot expiration quickly approaching on Oct. 31.
Maryland announced in January that it would continue operating under the 2014 pilot research program for the 2020 season.
The state legalized hemp production in April 2018, with no limits on how the plant can be used.
Maryland also has an established medical marijuana market.
