A hemp plant genetically engineered to produce lower levels of the cannabinoids THC and cannabichromene (CBC) “may be safely grown and bred in the United States,” the U.S. Department of Agriculture (USDA) has announced.
The hemp plant was genetically modified and submitted for review by Growing Together Research, a biotechnology firm headquartered in Fort Wayne, Indiana. The company announced earlier this year that it had achieved “the first known stable transformation and regeneration of multiple THC-free hemp cultivars” and in June announced it would work to increase THC production in cannabis plants.
“We reviewed the modified hemp plant to determine whether it posed an increased plant pest risk as compared to cultivated hemp,” USDA’s Animal and Plant Health Inspection Service (APHIS) said in a notice last week. “APHIS found this modified hemp is unlikely to pose an increased plant pest risk compared to other cultivated hemp.”
It its request for the USDA review, Growing Together Research said the changes are intended to make the engineered plants free of THC and CBC and also boost resistance to the herbicide bialaphos. It says genes in the new hemp plants came from multiple donor organisms, including plants, bacteria, a virus and at least one artificial sequence.
The company said in the request that it believes the intended resistance to the herbicide “is not expected to result in any other material changes to metabolism, physiology or development of the plant.”
The APHIS review focused on whether the new hemp plant poses a “plant pest risk.” The process, according to the agency, “examines the plant pests and diseases that are known to be associated with a commodity, identifies those pests that are likely to remain on the commodity upon importation into the United States, and evaluates the mitigations that may be required to avoid, reduce, or eliminate the risk of pest introduction into the United States.”
