The longer you smoke, the more vulnerable you become to dying early.
In the US, a predominant percentage of lung cancer deaths is due to smoking. Secondhand smoke also claims thousands of lives every year in the US by causing lung cancer. Smoking also increases the risk of contracting cancers of the esophagus, larynx (voice box), throat, oral cavity, lips, bladder, kidney and pancreas. Women become more vulnerable to cervix and uterus cancers.
Besides lung cancer, smoking can also cause chronic bronchitis, emphysema and chronic obstructive pulmonary disease (COPD).
Other Health Complications
Smoking can narrow blood vessels and restrict blood circulation to the brain, heart and other vital organs. Smoking also increases the viscosity of blood, increasing the risk of blood clot formation in the lungs and legs. You can also become more susceptible to stroke and heart attack.
Pregnant women who smoke increase the risk of preterm delivery, babies with low weight and even stillbirth.
