Researchers are not giving up on genetic engineering, though. The production of THC from yeast is desirable as it makes THC affordable and easy to obtain, clearly a win-win situation for both patients and scientists. Patients who need THC could purchase the less expensive form of the chemical derived from yeast instead of opting for chemically synthesized pills, which tend to be expensive for consumers. It also spares patients and scientists from the complicated issue of growing and obtaining medical marijuana plants. Yeast production also may improve access to THC and marijuana’s other medically-important constituents, making it possible to test the medical effectiveness of THC, cannabidiol, and other chemicals in both animal and human studies.
