It is generally believed that tobacco originated in America. Archaeological findings show that tobacco entered the lives of American residents when human beings were still in primitive society. At that time, when people were gathering food, they would unconsciously pick a plant leaf and put it in their mouth to chew. Because it is irritating, it just plays the role of restoring physical strength and refreshing, so they often pick it and chew it, which becomes a hobby.
Archaeologists believe that the earliest evidence of human use of tobacco so far is the relief in a temple built in 432 AD in Belenke, Chiapas, southern Mexico. It is a semi-relief painting, which shows a Maya with a long pipe and a pipe. At the ancestor worship ceremony, the pipe blows smoke and the head is wrapped with tobacco leaves.
Archaeologists also found tobacco and ash residues in caves inhabited by Indians in northern Arizona, USA. According to textual research, the age of these relics is about 650 AD. According to records, Salvadorans smoked tobacco in14th century.
