Cindy Fazey, former Chief of Demand Reduction for the United Nations Drug Control Programme, has pointed out that it would be nearly impossible to loosen international cannabis regulations. Even if the Commission on Narcotic Drugs removed cannabis from Schedule IV of the Single Convention, prohibitions against the plant would remain imbedded in and other parts of the treaty. Fazey cited amendment of the Articles and state-by-state denunciation as two theoretical possibilities for changing cannabis' international legal status, while pointing out that both face substantial barriers.
