The practice of consuming fungi and other psychoactive plants among ancient Central American civilizations are not well known. However a recent study of archeological artifacts and records revealed that not only were mind-altering plants such as tobacco, fungi and morning glory commonly used in Pre-Columbian Costa Rica territory, but it was also deeply ingrained in their culture and everyday lives.
The study conducted by the University of Costa Rica was based on collections from the Museums of the Central Bank of Costa Rica and the National Museum of Costa Rica. Some of the fascinating discoveries the team found were stone sculptures depicting figures smoking in what appears to be cigars as well as anthropomorphic ceramic inhalers which were used during celebrations or shamanistic rituals.
