Each year, the World Health Organisation (WHO) observes 31st May as ‘World No Tobacco Day’ to emphasize the lethal health risks associated with tobacco.
To fight against the global tobacco epidemic, this year, the movement will stress on defying the tobacco industry’s bold and increasingly dangerous efforts to dilute the WHO Framework Convention on Tobacco Control (WHO FCTC).

What is tobacco?
Tobacco is a name for any plant of the genus Nicotiana of the Solanaceae family (nightshade family) and for the product manufactured from the leaf and used in cigars and cigarettes, snuff, and pipe and chewing tobacco.
What are the substances found in tobacco?
2000- 4000 chemicals, 250- highly toxic chemicals and >50carcinogens.
Polycyclic aromatic hydrocarbons: Carcinogenic
Types of tobacco products:
|Smoke form||Smokeless form|
Which tobacco product has the most nicotine?
What does nicotine do to our health? And who is likely to become addicted to cigarette smoking?
Nicotine is an alkaloid present in tobacco, binds to the receptors present in the brain and leads to the release of catecholamines which causes -
Increase in heart rate
Increase in BP
Increase in cardiac contractility and output
People who start cigarette smoking at young age are likely to become addicted to smoking.
Effects of smoking while pregnant:
Effects of smoking while pregnant are-
Premature rupture of membranes
Increased risk of spontaneous abortion
Increased risk of perinatal mortality
Small for gestational age
Increased risk of infant respiratory distress syndrome
Does smoking affect fertility?
Yes, smoking is detrimental to your health, so it can severely affect your fertility:
The tar content of the tobacco damages the tunica intima of the blood vessels leading to plaque formation and then the plaque obstructs the lumen of blood vessels.
Nicotine is a vasoconstrictor. If it constricts coronary arteries that leads to heart attacks; similarly if it constricts penile arteries that leads to erectile dysfunction, leading to male impotence.
Tobacco is harmful to ovaries. Nicotine and other harmful chemicals in tobacco reduce the production of estrogen, a harmone that regulates folliculogenesis and ovulation. It also interferes with embryo transport, endometrial receptivity, endometrial angiogenesis, and uterine blood flow.
What is the prevalence of tobacco consumption and how many people die from smoking in the world each year?
Prevalence of tobacco use among adolescents, by sex and WHO region:
|WHO Region||Current smokers||Currently used tobacco products other than cigarettes|
| ||Total %||Boys %||Girls %||Total %||Boys %||Girls %|
|Eastern Mediterranean Region||4.9||7.3||2.0||12.0||14.3||9.1|
|South East Asian Region||5.9||9.5||2.0||10.1||12.5||7.1|
|Western Pacific Region||13.4||18.5||8.4||6.6||7.2||6.1|
Nearly 5 million deaths occurred each year in the world because of smoking.
If I smoke for a while and then I quit, is there any danger?
Yes, smoking for any amount of time is always dangerous.
How dangerous is second hand smoke/ environmental tobacco smoke (ETS) to the human health?
Second hand smoke is composed of side stream smoke (the smoke released from the burning end of a cigarette) and exhaled mainstream smoke (the smoke exhaled by the smoker). Because side stream smoke is generated at lower temperatures and under different conditions than mainstream smoke, it contains higher concentrations of many of the toxins found in inhaled cigarette smoke. Second hand smoke contains at least 250 toxic chemicals.
The contents of second hand smoke/environmental tobacco smoke (ETS) are same as that of first hand active smoke and so the effects are same as that of first hand active smoking. It mainly increases the risk of lung cancer.
How does tobacco use affect the country`s economy?
Direct medical costs of treating tobacco related diseases in India amounted to $907 million for smoked tobacco and $285 million for smokeless tobacco. The indirect morbidity costs of tobacco use, which include the cost of caregivers and value of work loss due to illness, amounted to $398 million for smoked tobacco and $104 million for smokeless tobacco. The total economic cost of tobacco use amounted to $1.7 billion.
Tuberculosis accounted for 18% of tobacco-related costs ($311 million) in India. Of the total cost of tobacco, 88% was attributed to men. The cost of tobacco use was many times more than the expenditure on tobacco control by the Government of India and about 16% more than the total tax revenue from tobacco. The tobacco-attributable cost of tuberculosis was also three times higher than the expenditure on tuberculosis control in India. The economic costs estimated here do not include the costs of premature mortality from tobacco use, which is known to comprise roughly 50% to 80% of the total economic cost of tobacco in many countries.
