Boldsky | 17th Feb, 2020 08:00 PM
  • 1. Cancer

    Smoking is the number one cause of cancer and death from cancer. Lungs, mouth, throat and gullet cancer are caused by the carcinogens or cancer-causing agents present in cigarettes. Smoking causes almost 90 per cent of lung cancer cases [4]. It also causes bladder, pancreas, cervical, kidney and oesophagus cancer [5].

    Smoking is the number one cause of bladder cancer, and increases the risk of developing liver cancer and cervical cancer. Studies also point out that those who smoke are more likely to die from colorectal cancer [6][7].


  • 2. Chronic Obstructive Pulmonary Disease (COPD)

    Chronic obstructive pulmonary disease (COPD) which includes chronic bronchitis and emphysema are caused by smoking. It blocks the airflow and causes difficulty in breathing. If you are a long-term smoker, the greater your risk will be of affecting severe COPD. The final stage of COPD is death from being unable to breathe [8].


  • 3. Cardiovascular Diseases

    Smoking results in death caused by diseases affecting the heart, blood vessels of the heart and other blood vessels [9]. Smoking increases cholesterol levels, causing cholesterol and other fats to be deposited in the arteries. This blocks the arteries and causes blood clots, increasing the risk of cardiovascular diseases [10].


  • 4. Reproductive Health Issues

    Smoking also adversely affects reproductive health, causing infertility, pre-term delivery, miscarriage, stillbirth and sudden infant death syndrome (SIDS) [11]. Men who frequently smoke have a greater risk of suffering from erectile dysfunction [12].


  • 5. Cataracts

    An ophthalmological condition, cataracts develop when the lens of the eye becomes opaque over time, resulting in loss of vision [13]. Studies link smoking with this condition and assert that smoking can increase the risk of cataracts [14].


  • 6. Type 2 Diabetes

    Reports and studies suggest that smoking is a direct cause of type 2 diabetes. Individuals who smoke have a 30-40 per cent increased risk of developing the condition [15]. Also, diabetics who smoke will find it difficult to manage the condition, which may lead to increased chances of heart disease, ulcers, infections and amputations [16].


  • 7. Increased Infections

    The risk of infections affecting your upper respiratory tract and lung increases. Smoking prevents bacteria and debris from being cleared from the lungs and respiratory tracts, resulting in sinusitis, bronchitis and pneumonia [17].


  • 8. Rheumatoid Arthritis

    Studies have pointed out that smoking increases your chances of developing rheumatoid arthritis [18]. The condition causes inflammation in the joints, pain, deformities and immobility [19].


  • 9. Aortic Aneurysm

    Aortic Aneurysm is an abnormal bulge in the wall of the major blood vessel (aorta) that carries blood from your heart to your body [20]. Aneurysms are more common in men than in women and the risk for an aortic aneurysm increases even more in men who smoke [21].


  • On A Final Note

    Inhaling secondhand smoke also causes lung disease in non-smoking adults, and raises the risk of heart disease by 25-30 per cent [22]. Children exposed to cigarette smoke are at a greater risk of SIDs, severe asthma, bronchitis and passive smoking even decrease the growth of their lungs.

    Quitting can help reduce the risk of suffering from diseases caused by smoking, as well as improving your overall health. Researches have found that every 7 minutes, a death is caused due to tobacco use [23].

Despite several measures taken up by the government and other non-governmental organizations to curb tobacco usage, still, its usage has remained all-time high.

The nicotine content in the cigarettes gets absorbed and penetrates the bloodstream via lungs and stimulates the electrical activity in the brain and also has a soothing effect especially when stressed. Of all the forms of tobacco, studies have shown that smoking accounts for almost 25 per cent of deaths annually in the age group of 30-60 years globally [1][2].

That is, smoking claims the lives of over seven million people each year and those around 900,000 non-smokers die each year, due to the exposure to the second-hand smoke. It should be understood that tobacco use, especially smoking is one of the major risk factors for various diseases [3].
