Since 1971, a single facility at the University of Mississippi has been in charge of producing cannabis plants for research purposes at the federal level. This monopoly prevented other facilities (public and private-owned) from growing marijuana for experimental reasons. In 2016, the DEA began to remove the monopoly on marijuana for medical research. Finally, they achieved what they set out to do in May 2021. The applications of several cannabis companies were approved by mid-2021. Groff Hemplex and the Biopharmaceutical Research Company revealed that they have been fully registered in the DEA database and have started cultivating cannabis plants. The first phase of harvest, which started about a month ago, will be forwarded to research facilities. Marijuana researchers across the country have commended this development.
