Smoking is something which is really common nowadays, many people smoke from various age groups, from teenagers to adults. Recently there has been a band on where the public are allowed to smoke, for example individuals are not allowed to smoke in pubs anymore even though up until recently you could this shows the positive steps which are being taken in order to help this problem of smoking. There are also many health risks which are involved with smoking. Cigarettes contain more than 4000 chemical compounds and at least 400 toxic substances. When you inhale, a cigarette burns at 700°C at the tip and around 60°C in the core. This heat breaks down the tobacco to produce various toxins. As a cigarette burns, the residues are concentrated towards the butt. The products that are most damaging are: tar, a carcinogen (substance that causes cancer)
nicotine is addictive and increases cholesterol levels in your body carbon monoxide reduces oxygen in the body components of the gas and particulate phases cause
chronic obstructive pulmonary disorder (COPD).The damage caused by smoking is influenced by: the number of cigarettes smoked whether the cigarette has a filter how the tobacco has been prepared. http://www.netdoctor.co.uk/health_advice/facts/smokehealth.htm. Research has shown that smoking reduces life expectancy by seven to eight years. Of the 300 people who die every day in the UK as a result of smoking, many are comparatively young smokers. The number of people under the age of 70 who die from smoking-related diseases exceeds the total figure for deaths caused by breast cancer, AIDS, traffic accidents and drug addiction. http://www.netdoctor.co.uk/health_advice/facts/smokehealth.htm. Another factor which has risen to mind is about passive smoking and the effects passive smoking have on people. This is also a rising concern for people, who inhale passive smoking. The 'side-stream' smoke that comes off a cigarette between puffs carries a higher risk than directly inhaled smoke.Children who grow up in a home where one or both of their parents smoke have twice the risk of getting asthma and asthmatic bronchitis. They also have a higher risk of developing allergies.Infants under two years old are more prone to severe respiratory infections and cot death. For adults, passive smoking seems to increase the risk of lung cancer, but the evidence for an increased risk of heart disease is not yet conclusive. http://www.netdoctor.co.uk/health_advice/facts/smokehealth.htm.
