The United Nations International Narcotics Control Board (INCB) has published on their website their annual report about the world situation on drugs in 2010. In this report, the INCB has included the preoccupying recommendation towards governments to outlaw  traditional plants such as Ayahuasca (a decoction made with botanicals like Banisteriopsis Caapi and Psychotria Viridis) and Tabernanthe Iboga among others, neglecting their important role as traditional medicine, as a sacrament and as therapeutic tool. These are the primary uses of these plants found in societies all over the world.   link
