			<content:encoded><![CDATA[<p>History of tobacco began apparently 50,000 B.C.E. Humans may have begun chewing tobacco species.<br />
There is evidence in history of tobacco that it has been consumed as a drink, in the form of an infusion; it has been chewed; and it has been taken in powder form in the mouth and as a nasal preparation.<br />
Tobacco leaves have been consumed in many ways, all of which, with the exception of the modern cigarette, were known in the Americas before the arrival of Christopher Columbus at the end of the fifteenth century.<br />
So tobacco had already long been used in the Americas when European settlers arrived and introduced the practice to Europe, where it became popular.<br />
Jean Nicot, France’s ambassador to Portugal, writes of tobacco’s medicinal properties. In that period of history of tobacco nicotine was describing as a panacea. Nicot sends rustica plants to French court. In 1561 Nicot sends snuff to Catherine de Medici, the Queen Mother of France, to treat her son Francis II’s migraine headaches.<br />
In long history of tobacco remarkable fact is that nicotine was first isolated from the tobacco plant in 1828 by German chemists Posselt &amp; Reimann. Its chemical empirical formula was described by Melsens in 1843, its structure was discovered by Adolf Pinner in 1893, and it was first synthesized by A. Pictet and Crepieux in 1904.<br />
New history of tobacco begun from 1938 when  Dr. Raymond Pearl of Johns Hopkins University reports to the New York Academy of Medicine that smokers do not live as long as nonsmokers. Then in 1950 five important epidemiological studies show that lung cancer patients are more likely to be smokers than are other hospital patients.<br />
In our days in spite of advertising and promotion bans history of tobacco continues.</p>
