This is knowledgeable and theoretical research on the habitual attitudes of smokers when they are exposed to the social environment. It provides arguable theories and knowledge to authenticate all data collection and findings. A lot of research has gone into discovering the hazards of cigarettes. Every day many new discoveries add to the list of the yet-not-complete catalogue of cigarettes hazards. Cancer, one of the most deadly diseases, has been confirmed to have an association with cigarette smoking. Especially the lungs and stomach are at high risk to develop cancer due to smoking. Many skin diseases have been identified to be triggered by smoking, like infectious eczematoid dermatitis and Hidradenitis suppurativa are to name a few. The most important part of the human body – the brain is affected too by cigarettes.
Nicotine which is present in cigarettes is researched to be responsible for the death of brain cells and nervous system abnormal functionality. Smokers are more likely to develop heart diseases and heart strokes as compared to non-smokers. The throat and respiratory canal are directly exposed to the harmful fumes of tobacco. Hence they get potentially at an even greater risk of developing cancer. The mouth and teeth are other parts that receive the smoke directly, and hence they too are at risk of developing abnormalities due to cigarettes. Smoking is the major risk factor in the development of cancer and heart diseases. Smoking not only affects the smoker but also makes environmental pollutants causing passive smoke in non-smokers.
