Americans have many controversial topics on their minds in today's society such as abortion, the use of handguns, and one of the most controversial topics is smoking in public. There are many things that can happen when you smoke, for example, causing air pollution, causing diseases in nonsmokers, and finally causing harm to smokers themselves. In some countries, smoking is already banned in a few of these public places such as bars, restaurants, clubs, toilets, sporting stadiums, cinemas, work, street shops, schools, and transports. The U.S. food and drug administration (FDA) has asserted that cigarettes and smokeless tobacco should be considered nicotine delivery devices.
The active ingredient in tobacco is nicotine that is inhaled into the lungs where most of it stays. The rest passes into the bloodstream, reaching the brain in about ten seconds and dispersing throughout the body in about twenty seconds. Nicotine, by itself, increases the risk of heart disease. However, when a person smokes, he or she is ingesting a lot more than nicotine. Smoke from a cigarette, pipe, or cigar is made up of many additional toxic chemicals including tar and carbon monoxide. Tar is a sticky substance that forms into deposits in the lungs, causing lung cancer and respiratory distress. Carbon monoxide limits the amount of oxygen that the red blood cells can convey throughout your body. Also may damage the inner walls of the arteries, which allows fat to build up in them.
Tobacco smoke is killing thousands of people every year and injuring hundreds of thousands more every day like children. Smoking is recognized as the leading preventable cause of death, causing or contributing to the deaths of 430,700 Americans each year. Anyone with a smoking habit has an increased chance of lung, cervical, and other types of cancer; respiratory diseases such as emphysema, asthma, and chronic bronchitis; and cardiovascular disease, such as heart attack, high blood pressure, stroke and arteriosclerosis.
