Tobacco has a long history from its usages in the early Americas. Increasingly popular with the arrival of Spain to America, which introduced tobacco to the Europeans by whom it was heavily traded. Following the industrial revolution, cigarettes were becoming popularized in the New World as well as Europe, which fostered yet another unparalleled increase in growth. This remained so until scientific studies in the mid-1900s demonstrated the negative health effects of tobacco smoking including lung and throat cancer.
Tobacco was first discovered by the native people of Mesoamerica and South America and later introduced to Europe and the rest of the world.
Tobacco had already long been used in the Americas by the time European settlers arrived and took the practice to Europe, where it became popular. Eastern North American tribes have historically carried tobacco in pouches as a readily accepted trade item, as well as smoking it in pipe ceremonies, whether for sacred ceremonies or those to seal a treaty or agreement. Tobacco is considered a gift from the Creator, and tobacco smoke is seen as carrying one's thoughts and prayers to the spirits.
In addition to its use in spiritual ceremonies, tobacco is also used in ethnobotany for medical treatment of physical conditions. As a pain killer it has been used for earache and toothache and occasionally as a poultice. Some indigenous peoples in California have used tobacco as one ingredient in smoking mixtures for treating colds; usually it is mixed with the leaves of the small desert sage, Salvia dorrii, or the root of Indian balsam or cough root, Leptotaenia multifida (the addition of which was thought to be particularly good for asthma and tuberculosis). In addition to its traditional medicinal uses, tobacco was also used as a form of currency between Native Americans and Colonists from the 1620s on.
