Tobacco is the common name of several plants in the Nicotiana genus and the Solanaceae (nightshade) family, and the general term for any product prepared from the cured leaves of the tobacco plant. More than 70 species of tobacco are known, but the chief commercial crop is N. tabacum. The more potent variant N. rustica is also used around the world.
Tobacco contains the stimulant alkaloid nicotine as well as harmala alkaloids. Dried tobacco leaves are mainly used for smoking in cigarettes, cigars, pipes, shishas as well as e-cigarettes (both rechargeable and disposable), e-cigars, e-pipes and vaporizers. They can also be consumed as snuff, chewing tobacco, dipping tobacco and snus.
Tobacco use is a risk factor for many diseases; especially those affecting the heart, liver, and lungs, as well as many cancers. In 2008, the World Health Organization named tobacco use as the world's single greatest preventable cause of death.
Tobacco has long been used in the Americas, with some cultivation sites in Mexico dating back to 1400–1000 BC. Many Native American tribes have traditionally grown and used tobacco. Eastern North American tribes 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. In some populations, tobacco is seen as a gift from the Creator, with the ceremonial tobacco smoke carrying one's thoughts and prayers to the Creator.
Following the scientific revelations of the mid-20th century, tobacco became condemned as a health hazard, and eventually became encompassed as a cause for cancer, as well as other respiratory and circulatory diseases. In the United States, this led to the Tobacco Master Settlement Agreement, which settled the lawsuit in exchange for a combination of yearly payments to the states and voluntary restrictions on advertising and marketing of tobacco products.
In the 1970s, Brown & Williamson cross-bred a strain of tobacco to produce Y1. This strain of tobacco contained an unusually high amount of nicotine, nearly doubling its content from 3.2-3.5% to 6.5%. In the 1990s, this prompted the Food and Drug Administration to use this strain as evidence that tobacco companies were intentionally manipulating the nicotine content of cigarettes.
In 2003, in response to growth of tobacco use in developing countries, the World Health Organization successfully rallied 168 countries to sign the Framework Convention on Tobacco Control. The convention is designed to push for effective legislation and its enforcement in all countries to reduce the harmful effects of tobacco. This led to the development of tobacco cessation products.
Tobacco is cultivated annually, and can be harvested in several ways. In the oldest method still used today, the entire plant is harvested at once by cutting off the stalk at the ground with a tobacco knife. It is then speared onto sticks, four to six plants a stick and hung in a curing barn. In the 19th century, bright tobacco began to be harvested by pulling individual leaves off the stalk as they ripened. The leaves ripen from the ground upwards, so a field of tobacco harvested in this manner involves the serial harvest of a number of "primings", beginning with the volado leaves near the ground, working to the seco leaves in the middle of the plant, and finishing with the potent ligero leaves at the top. Before this, the crop must be topped when the pink flowers develop. Topping always refers to the removal of the tobacco flower before the leaves are systematically removed, and eventually, entirely harvested. As the industrial revolution took hold, harvesting wagons used to transport leaves were equipped with man-powered stringers, an apparatus that used twine to attach leaves to a pole.
