Tobacco, taken in any form, can lead to many diseases, including cancers. According to the data collected from the Global Adult Tobacco Survey, in low and middle-income countries (including India), 41% of men and 5% of women are smokers.

Tobacco is used in the form of smoking, chewing, sniffing, and dipping. Among them, smoking is the most prevalent form. There are many diseases caused by smoking, like peripheral arterial disease, stroke, heart disease, and lung diseases like chronic obstructive pulmonary disease

(COPD); however, the most dreaded and frightening disease is cancer.

  • Lung.

  • Bladder.

  • Cervix.

  • Colon and rectum.

  • Kidney.

  • Larynx.

  • Liver.

12. Blood Clots - Blood clots are commonly seen in people who smoke. It increases the risk of heart attack, pulmonary embolism, and stroke.

13. Accelerates Aging - Less blood flow due to constricted vessels results in poor nutrition supply to the skin. This stimulates the occurrence of wrinkles and fine lines and makes the individual look older.

14. Yellow Fingers and Teeth - Nicotine stains can make your nails and teeth look dirty and yellow, resulting in an unpleasant smile. Apart from this, smoking increases the deposition of tartar, making the gums weaker and ultimately losing the tooth.

15. Loss of Appetite- Overall general health gets affected because the person feels less hungry.

16. Vision Problems - It increases the risk of eye problems like cataracts, glaucoma, and macular degeneration.

17. Early Menopause - Women who smoke enter menopause earlier.

Extending support and addressing the addiction and habit of smoking can help prevent smoking. Enforcement of strict laws, regulating tobacco products, and having smoke-free policies are some ways to prevent smoking.


To What Extent Does Smoking Increase the Chances of Death?

A smoker loses at least 11 minutes of their life with every cigarette. In addition, smoking remains one of the significant risk factors for lung cancer. According to the Centers for Disease Control (CDC), quitting smoking before the age of 40 can reduce the risk of dying from cancer by 90 %.


Cessation of Smoking Is Categorized in Which Type of Prevention?

Smoking cessation is a primary prevention type related to preventing smoking initiation. Primary prevention is achieved by reducing exposure to risk factors, such as age-limit purchasing, smokeless zones, and restrictions at the school, especially among the youth and lower-income people.


What Makes People Smoke?

Smoking tobacco releases dopamine in the brain, which makes the person feel good. Unfortunately, over time the brain starts to crave the same feeling and tempts them to take more and more tobacco. Nicotine in cigarettes is the main ingredient to make one addicted to smoking. Other factors may include peer pressure, parental influence, stress factors, and influence by the media.


What Makes a Person Choose Smoking?

Smoking is a voluntary decision that many smokers report to increase their focus. Smokers claim smoking speeds up their action and concentration and thereby enjoy the ritual of smoking. Often smoking is seen as a lifestyle choice along with drinking alcohol, as it has a powerful influence on an individual's perception.


Who Are More Vulnerable to Smoke?

Smoking is primarily reported in the age group of 18 to 28 years, who usually start smoking to get a feel for it or presume it is an incredible act. Poor people living in stressful conditions often turn to smoking. Smoking cigarettes and using other tobacco products is more evident in men than women.


Does Smoking Justify as a Human Right?

Smoking tobacco is a personal decision of a person. However, smoking in public places can pollute the environment. It creates unhealthy air for non-smokers, violating their fundamental rights per the constitutional provisions. Furthermore, smoking increases the risk of cancer of second-hand smokers and should be discouraged.


Is It Okay to Have Ten to Twelve Cigarettes a Day?

Smoking cigarettes can increase the risk of cancer when compared to non-smokers. Smoking excessively (ten to twelve cigarettes) increases the risk of coronary heart disease and stroke by 40 percent. It also increases the risk of lung cancer and lung diseases, such as emphysema and chronic obstructive pulmonary disease (COPD). In addition, chemicals inhaled during smoking can cause irreparable damage to the mind and body.


Does Smoking Relieve Tension and Stress?

Nicotine in the cigarette is a mood-altering drug that camouflages frustration, anger, and anxiety. It affects the dopamine release in the brain resulting in the person experiencing positivity and calm. However, the increase in dopamine is short–lived and can cause withdrawal symptoms.

Is It Possible for Smokers to Have Healthy Lungs?

Mutations in specific patients' DNA (deoxyribonucleic acid) can enhance their lung function and mask the impact of smoking. In addition, the genetic variants of these people allow them to have a healthy life despite long-term exposure to carcinogens that do not develop cancers or other lung diseases.


What Is More Dangerous, Obesity or Smoking?

Obesity rates put people at higher risk of many life-threatening diseases, including cancer and heart problems. Obese patients are at increased risk for other chronic conditions that may further weaken the immune system, leaving the body unable to fight infections or diseases.


Can Smoking Affect Running?

Smoking cigarettes decreases lung capacity or affects performance. Running requires more oxygen. The increased tissue inflammation and narrow airways result in less oxygen supply to the lungs, resulting in decreased energy and strength. A smoker fails to have better blood circulation and low oxygen levels.
