As of 2010, approximately 5.5 trillion cigarettes are produced globally each year and are smoked by over 1.1 billion people or greater than one-seventh of the world population. While smoking rates have leveled off or declined in developed nations, they continue to rise in developing parts of the world. Smoking rates in the United States have dropped by half from 2006 to 2012 falling from 42% to 20.8% of adults. In the developing world, tobacco consumption is rising by 3.4% per year. On average, each cigarette that is smoked is estimated to shorten life by 11 minutes. Starting smoking earlier in life and smoking cigarettes higher in tar increases the risk of these diseases.
Nicotine, the primary psychoactive chemical in cigarettes, is addictive. The resulting use of tobacco is the single greatest cause of preventable death globally. Smoking leads most commonly to diseases affecting the heart, liver and lungs, being a major risk factor for heart attacks, strokes, chronic obstructive pulmonary disease including emphysema and chronic bronchitis, and cancer--particularly lung cancer, cancers of the larynx and mouth, and pancreatic cancer. It also causes peripheral vascular disease and hypertension. The World Health Organization (WHO) estimates that tobacco caused 5.4 million deaths in 2004 and 100 million deaths over the course of the 20th century. There are, however, some potential health benefits to smoking: According to a review of epidemiological studies “cigarette smokers are 50% less likely to have PD or AD than are age- and gender-matched nonsmokers." "Ulcerative colitis is a condition of nonsmokers in which nicotine is of therapeutic benefit."
Cigarettes affect people's health, at this time, electronic was produced. Electronic cigarettes, commonly called e-Cigarettes, are nicotine delivery devices which, may or may not, resemble cigarettes, and produces vapor rather than smoke. These devices are illegal in some countries, such as Singapore and Malaysia. In other countries, these devices require government approval before these products can be sold, such as Canada and Denmark. Because they contain no tobacco, e-cigarettes aren't subject to U.S. tobacco laws, which mean they can be purchased without proof of age, especially online. This raises concerns that e-cigs may be particularly appealing to kids and may encourage nicotine addiction among young people. And while manufacturers of the e-cigarette claim that it's the cigarette you can "smoke" anywhere, regulatory agencies around the world are taking a close look at these gadgets and instituting a range of restrictions on their use.
Most "e-cigs" are similar enough in appearance to be mistaken for regular cigarettes, but one look inside and you'll see the main difference: E-cigarettes don't contain tobacco. Instead, there's a mechanism that heats up liquid nicotine, which turns into a vapor that smokers inhale and exhale. Manufacturers and satisfied customers say that this nicotine vapor offers many advantages over traditional cigarette smoke. But regulatory agencies and some health experts aren't sure.
