why do they put tar in cigarettes
Like the other scientists have pointed out, tar isnвt actually an ingredient in cigarettes. But I have been asking myself a similar question for a very long time: why are people still smoking cigarettes when we know about the health consequences?! This is a complex issue. People seem to smoke because they think itвs cool and want to impress other people. Another reason is money. The UK government taxes cigarettes. This means that they increase the price of the cigarette packet and keep the profit for themselves. I personally think itвs crazy to think that the government is profiting at the expense of peoplesв health. But one argument is that it would be impossible to ban smoking because there will always be people who want to smoke.
So instead of banning cigarettes, the government just makes it very expensive to smoke.
One of the most known diseases caused by smoking is lung cancer. A few commonly found in tar include, and. Smoking exposes delicate cells inside the lungs directly to these compounds. This causes mutations in the DNA of the cells, which leads to cancer. According to the World Health Organization's report, "Tobacco Smoke and Involuntary Smoking," 90 percent of all cases of lung cancer are attributable to smoking. is residual nicotine and other chemicals left on a variety of indoor surfaces by tobacco smoke.
This residue reacts with indoor pollutants to create a toxic mix. Containing cancer-causing substances, this third-hand smoke poses a potential health hazard to nonsmokers who are exposed to it, especially children. Studies have shown that third-hand smoke clings to many things such as hair, skin, clothes, furniture, drapes, walls, bedding, carpets, dust, vehicles and other surfaces, even long after smoking has stopped. Individuals at risk such as infants, children and nonsmoking adults may suffer tobacco-related health problems when they inhale, ingest or touch substances containing third-hand smoke. Third-hand smoke is a relatively new concept, and researchers are still studying its possible dangers.
Third-hand smoking can be a serious concern, as it affects other people's health. In a house, the tobacco residue of the smoke can build up on surfaces over time. Unfortunately, excess smoke can not be removed just by airing out rooms and opening windows. Scientists have reported that third-hand smoke may cause up to 60 percent of the harm caused by regular exposure to smoke. (SHS) is a combination of (i. e. , smoke emitted from the burning cigarette, pipe, or cigar) and the mainstream smoke exhaled from the lungs of smokers. It contains more than 4,000 chemicals, many of which are known to affect health.
These may include ammonia, acrolein, carbon monoxide, hydrogen cyanide, nicotine, nitrogen oxides, and sulfur dioxide, many of which contain irritants and toxicants to the eye and respiratory tract. Third-hand smoking (THS) consists of residual tobacco smoke pollutants that remain on surfaces and in dust after tobacco has been smoked, are re-emitted into the gas phase, or react with oxidants and other compounds in the environment to yield secondary pollutants. Chemicals of tobacco smoking include nicotine, 3-ethenylpyridine (3-EP), phenol, cresols, naphthalene, formaldehyde, and tobacco-specific nitrosamines (including some not found in freshly-emitted tobacco smoke).
