Smoking tobacco is a popular drug-consumption method wherein tobacco smoke in inhaled to uptake the nicotine. can lead to dangerous addictions that cause cancer or death. Every year, about four hundred forty thousand people die in the United States because of tobacco addictions, which is about twenty percent of all deaths in the United States. Cigarettes kill more Americans than AIDS, homicide, alcohol, car accidents, suicide, and illegal drugs combined. Tobacco is formed with over four thousand chemicals, none of them beneficial one's health. The possibility of lung cancer increases with the amount of tobacco smoked, duration of smoking, degree of inhalation, and tar and nicotine levels of the cigarettes. First used by North Americans, tobacco has been Europeans' favorite drug for many centuries. Tobacco quickly became famous due to its addictive chemical, nicotine. Nicotine disables the function of the brain, and therefore, smokers usually lose their sense. Cigarette flavors have gone through many changes since cigarettes were first made. At first, tobacco did not filter the tar coming through. Although fliters are now developed, they do not remove enough tar to make cigarettes any less dangerous.

Compositions
The compositions in tobacco delivered to smoker depends on the length of the column of tobacco, the amount of compositions packed, characteristics of the filter and the paper, and the temperature of the fire at which the tobacco is burned. There are over four thousand chemicals in a cigarette, which includes 43 known toxic compounds that cause cancer, and 400 other toxins. Most of these chemicals stay in the lungs when inhaled. The gaseous phase components in tobacco are carbon monoxide, carbon dioxide, nitrogen oxides, ammonia, volatile nitrosamines, hydrogen cyanide, volatile sulfur containing compounds, volatile hydrocarbons, alcohols and aldehydes and ketones. They preclude the ciliary movement of the lungs. Nicotine, highly addictive chemical, reaches the brain in just six seconds. Nicotine is a colorless and volatile liquid alkaloid. Nicotine stimulates the brain, and therefore, calms those who smoke tobacco. Once this lethal poison reaches the brain, it affects the heart, blood vessels, and hormones. Although smoking more makes it feel better, but it leaves great damage in the lungs and health of the body. The other significant chemical in a cigarette is tar, which forms a sticky mass in the lungs. The amount of tar inhaled increases as a cigarette is smoked, therefore, the last puff of smoke contains more than twice as much tar as the first puff of smoke.



Just one cigarette leaves noticeable amount of tar in the lungs. Tar contains over four thousand chemicals, and smoking daily for a year leaves one quart of tar in the lungs.

Bidis are rolled in a tendu or temburi leaf, plants native to Asia, and tied with strings on the end.

In 1612, when first settlers came to North America, tobacco was the main source of making money for settlers. Money made by selling tobacco helped settlers pay for the American Revolution. The first president of the U.S., George Washington, grew tobacco also. By the 1800's, more people learned and started smoking. They used pipe generally while some chewed. People smoked about forty cigarettes in a year back at the time. In 1881, James Bonsack invented the machine that produced cigarettes, which let the world pay attention to tobacco. First cigarette brand was called Duke of Durham, and was packed with baseball cards. He worked with Washington duke's son, James Buck Duke. Together, they made about 10 million cigarettes per a year, and about one billion cigarettes in their next five years. During World Wars, soldiers were given free cigarettes every day. Although tobacco was mainly sold to men, women became to know smoking while their husbands were away. Women smoked during their work time when their husbands went to fight. By 1944, cigarette was produced up to three-hundred billion per year. It was 1964 when smoking was proven harmful. The Surgeon General of the U.S., the chief doctor of the country, wrote how a cigarette can influence one's health. He stated that nicotine and tar in cigarettes cause lung cancer. Therefore, in 1965, every cigarette must have a warning sign, "Cigarette may be hazardous to your health." Later in 1980's, tobacco companies reduced the amount of nicotine and tar in a cigarette to keep their customers from their fear of smoking. "Tar wars" was called for this period of time, because many companies aggressively competed making low tar cigarettes.
