The cigarette is ignited at one end and allowed to smoulder for the purpose of inhalation of its smoke from the other (usually filtered) end, which is inserted in the mouth. They are sometimes smoked with a cigarette holder. The term cigarette, as commonly used, refers to a tobacco cigarette but can apply to similar devices containing other herbs, such as cannabis. Nicotine, the primary psychoactive chemical in tobacco, is addictive.[2] Cigarette use has also been shown to cause multiple types of cancer, heart disease, respiratory disease, circulatory disease, birth defects (which include mental and physical disability) and emphysema.[3][4] On average, each cigarette smoked shortens lifespan by 11 minutes.[5] Rates of cigarette smoking vary widely. While rates of smoking have leveled off or declined in the developed world, they continue to rise in the undeveloped world. [6][7] A cigarette is distinguished from a cigar by its smaller size, use of processed leaf, and white paper wrapping. Cigars are typically composed entirely of whole-leaf tobacco. Cigarettes are the most frequent source of fires in private homes and European Union wishes to ban in 2011 cigarettes that are not fire-safe[8]. Tobacco is an agricultural product, recognized as an addictive drug, processed from the fresh leaves of plants in the genus Nicotiana. Tobacco has long been in use as a entheogen. However at the arrival of the Europeans, it quickly became popularized as a trade item and as a recreational drug. This popularization led to the development of the southern economy of the United States until it gave way to cotton. Following the American Civil War, a change in demand and a change in labor force allowed for the development of the cigarette. This new product quickly led to the growth of tobacco companies until the scientific controversy of the mid-1900s. There are many species of Tobacco, which are all encompassed by the plant genus Nicotiana. The effects of tobacco on human health is significant depending on the method of which it used and the amount. Of the various methods of consumption the primary health risks pertain to diseases of the cardiovascular system by the vector of smoking, which overtime allows high quantaties of carcinogens to deposite in the moth, throat, and lungs. Because of the addictive properties of nicotine, tolerance and dependence develop. Absorption quantity, frequency, and speed of tobacco consumption are believed to be directly related to biological strength of nicotine dependence, addiction, and tolerance.[1][2] The usage of tobacco, is an activity that is practiced by some 1.1 billion people, and up to 1/3 of the adult population.[3] It is believed to be the second leading cause of death worldwide.[4] Rates of smoking has leveled off or declined in developed countries, however they continue to rise in developing countries. Tobacco is cultivated similar to other argicultural products. Seeds are sown in cold frames or hotbeds to prevent attacks from insects, and then transplanted into the fields. Tobacco is an annual crop, which is usually harvested in a large single-piece farm equipment. After harvest, tobacco is stored to allow for curing, which allow for the slow oxidation and degradation of carotenoids. This allows for the argicultural product to take on properties that are usually attributed to the "smoothness" of the smoke. Following this, tobacco is packed into its various forms of consumption which include smoking, chewing, sniffing, and so on.
