Cohoba is an old Spanish transliteration for a ceremony in which psychedelic ground seed of the cojóbana tree was smoked in twin nasal Y-shaped pipes also called Cohoba. The cojóbana tree is believed by some to be Yopo, Anadenathera peregrina http://www.quake-art.com/docs/Hallucinogenic%20Plants%20-%20A%20Golden%20Guide.pdf although perhaps it may have been a generalized term for psychotropics including various quite toxic Datura and related genera (Solanacea). The corresponding ceremony using cohoba-laced tobacco is transliterated as cojibá.
