Smoking is one of the leading global causes of preventable deaths, triggering the development of numerous types of cancer, particularly in the throat, lungs and mouth, cardiovascular disease, and respiratory disease. Initially, smokers or those living with smokers, may only develop mild, short-term health issues such as persistent coughing, throat irritation, heartburn or signs of asthma or allergy. But over time these conditions can easily develop into more serious health problems both in the lungs such as bronchitis and emphysema, and in the heart such as high blood pressure, narrowing or thickening of the blood vessels and clots which lead to stroke.
These health problems are not just affecting the adults who smoke, but are also causing similar developments in many of the children who are exposed to smoke in the air or even in the walls or from clothing of smokers around them or living in the same household. Second-hand smoke is what the smoke exhaled by a smoker is called along with the smoke that comes from the tip of burning cigarettes, pipes, and cigars. This smoke contains about 4,000 chemicals out of which at least 50 of them are known to cause cancer, and most of the rest are known to be highly dangerous. Anyone exposed to second-hand smoke are also exposed to these chemicals and will suffer the same health risks as the smoker.

Children are affected by not only second-hand smoke, but in households with one or more smokers, the residue of smoke remains in any fabrics, furniture and even the walls and floors, causing third-hand smoke risks that is harmful for health and development. Exposure to second or third-hand smoke can cause low birth weight, Sudden Infant Death Syndrome (SIDS), asthma, bronchitis, pneumonia, middle ear infection, and other diseases in both infants and older children.
