Sukia stone figurines like this one are common in Costa Rica.  The figurines depict an individual, likely a shaman, smoking or blowing a substance through a snuff tube. Consumption of hallucinogenic drugs were thought to bring one closer to the spirit world. The act depicted by may relate to a curing ritual performed to heal the sick and possessed.  These figures were possibly mass-produced and placed in homes and burials for protection of the living and the dead, much like how religious objects are placed in modern homes for a similar reason.
