5 Dangers of Smoking

1. Smoking is addictive. Nicotine is a drug that is naturally present in the tobacco plant and is primarily responsible for a person’s addiction to tobacco products, including cigarettes. The addiction to cigarettes and other tobacco products that nicotine causes is similar to the addiction produced by using drugs such as heroin and cocaine.

2. One cigarette reduces your life by 11 minutes. Smoking has been found to harm nearly every organ in the body and reduces a person’s overall health.

3. Smoking is a leading cause of cancer and death from cancer. It causes cancers of the lung, esophagus, larynx, mouth, throat, kidney, bladder, liver, pancreas, stomach, cervix, colon, and rectum.

4. Smoking causes heart disease, stroke, chronic obstructive pulmonary disease (COPD), emphysema, diabetes, osteoporosis, rheumatoid arthritis, age-related macular degeneration and cataracts, and worsens asthma symptoms in adults. Smokers are at higher risk of developing pneumonia, tuberculosis, and other airway infections, and smoking weakens the immune system.

5. Smoking makes it harder for a woman to get pregnant. A pregnant smoker is at higher risk of miscarriage, having an ectopic pregnancy, having her baby born too early and with an abnormally low birth weight, and having her baby born with a cleft lip and/or cleft palate. A woman who smokes during or after pregnancy increases her infant’s risk of death from Sudden Infant Death Syndrome (SIDS). Men who smoke are at greater risk of erectile dysfunction.
