1. History of smoking
1.1. Early use
Smoking has been practiced in one form or another since ancient times. Tobacco and various hallucinogenic drugs were smoked all over the Americas as early as 5000 BC in shamanistic rituals and originated in the Peruvian and Ecuadorian Andes.[2] Many ancient civilizations, such as the Babylonians, Indians and Chinese, burnt incense as a part of religious rituals, as did the Israelites and the later Catholic and Orthodox Christian churches.
In Ancient Greece, smoke was used as healing practice and the Oracle of Delphi made prophecies while intoxicated by inhaling natural gases from a natural bore hole. The Greek historian Herodotos also wrote that the Scythians used cannabis for ritual purposes and, to some degree, pleasure.
Smoking in the Americas probably originated in the incense-burning ceremonies of shamans, and was later adopted for pleasure or as a social tool.[5] The Maya employed it in classical times (at least from the 10th century) and the Aztecs included it in their mythology. The Aztec goddess Cihuacoahuatl had a body consisting of tobacco, and the priests that performed human sacrifices wore tobacco gourds as symbols of divinity. Even today certain Tzeltal Maya sacrifice 13 calabashes of tobacco at New Year.[3] The smoking of tobacco and various other hallucinogenic drugs was used to achieve trances and to come into contact with the spirit world. Reports from the first European explorers and conquistadors to reach the Americas tell of rituals where native priests smoked themselves into such high degrees of intoxication that it is unlikely that the rituals were limited to just tobacco. No concrete evidence of exactly what they smoked exists, but the most probable theory is that the tobacco was much stronger, consumed in extreme amounts, or was mixed with other, unknown psychoactive drugs.
