On May 25, 1999, MAPS successfully secured Orphan Drug Designation for Marijuana in the treatment of AIDS wasting syndrome. Since it is not possible to obtain a patent on marijuana for use as a prescription medicine, an Orphan Drug Designation makes marijuana available for research and development into a prescription medicine. The Orphan Drug Designation program was developed by congress to facilitate the development of rare drugs. In the years since MAPS obtained permission to study this treatment, the advent of protease inhibitors has largely eliminated AIDS wasting syndrome in the US. As a result, we have not pursued this research.
