Tobacco has long been used in the Americas, with some cultivation sites in Mexico dating back to 1400–1000 BC.[7] Many Native American tribes have traditionally grown and used tobacco. Eastern North American tribes have historically carried tobacco in pouches as a readily accepted trade item, as well as smoking it, both socially and ceremonially, such as to seal a peace treaty or trade agreement.[8][9]Traditionally, tobacco is seen as a gift from the Creator, with the ceremonial tobacco smoke carrying one's thoughts and prayers to the Creator.[10]
