Top 10 Ingredients in Cigarettes that are Harmful

2. Tar

Tar is a particulate matter created by burning tobacco and other substances in a cigarette. It contains a mixture of harmful chemicals which are toxic to the lungs. When cigarette filters were added to cigarettes, they were expected to stop the tar from going into the lungs, but it wasn’t very effective. The effects of tar are not restrained to smokers; it may be left behind in closed environments where smoking took place, exposing other people to its harmful effects. The characteristic brown stains on the teeth and fingers of consistent smokers come from tar. Not only is it responsible for several lung diseases, the compounds that it contains are carcinogenic in nature and increase chances of lung cancer.
