Health Effects Of Smoking

1. Affects sexuality and reproductive system

The nicotine in cigarettes disrupts blood flow to the genital areas in both men and women, thereby decreasing sexual performance and causing sexual dysfunction [2] . According to the American Cancer Society, smoking damages a woman's reproductive system which increases the chances of miscarriages, babies with cleft lip or palate, stillbirths, and low birth-weight babies.

2. Causes heart diseases

Lung diseases like chronic obstructive pulmonary disease, chronic bronchitis, emphysema are common among smokers [4] . Smoking also causes lung cancer in both men and women. It also increases the rate of pneumonia and asthma.

Smoking

4. Affects the central nervous system

Nicotine-derived nitrosamine ketone (NNK) is a chemical compound commonly found in tobacco. It is a precarcinogen which becomes a carcinogen after it gets altered by the metabolic process in the body. This compound provokes an exaggerated response from the brain's immune cells, known as microglia cells, which work by attacking the damaged cells. However, when provoked, the microglia cells instigate the white blood cells in the central nervous system to attack the healthy cells, leading to severe neurological depression. [5] .

5. Causes cancer

Smoking increases the risk of various types of cancers such as liver, mouth, pharynx, larynx, kidney, cervix, oesophagus, pancreas, stomach, bladder, colon/rectum, myeloid leukaemia. Smoking also increases the risk of squamous cell carcinoma, a type of skin cancer [6] .

Smoking has a negative effect on insulin levels which makes it more likely to develop insulin resistance and puts you at a risk of getting type 2 diabetes [7] .

The nicotine in smoking disrupts blood flow in the men's genital areas, constricting the blood vessels causing erectile dysfunction [8] .
