The health risks of smoking include increased risk of heart disease, stroke, lung cancer, and other cancers, as well as respiratory illnesses such as COPD (chronic obstructive pulmonary disease) and bronchitis. It can also lead to a weakened immune system, poor wound healing, and an increased risk of infection. Smoking can also cause fertility problems in women, as well as damage to your teeth and gums. In addition, it is associated with lower life expectancy, higher healthcare costs, and poorer quality of life.
