World No Tobacco Day is observed around the world every year on May 31st. The member states of World Health Organisation (WHO) created No Tobacco Day in 1987.

The day aims to reduce the 5.4 million yearly deaths from tobacco-related health problems from 1988. WHO has preented World No Tobacco Day (WNTD) awards to organisations or individuals who made exceptional contributions in reducing tobacco cosumption.

Cigarette Smonking

Tobbaco smoking is the practice where tobacco is burned and the vapours either tasted or inhaled Smoking is the most common method of consuming tobacco, and tobacco is the most common substance smoked.

Pathophysiological effects of smoking

While smoking, harmful substances quickly and effectively deliver into the bloodstream by absorption through the alevoli in the lungs. Some amount of the active substances will be lost in the process of combustion and Pyrolysis.

The inhaled substances trigger chemical reactions in nerve endings. The cholinergic receptiors are often triggered by the naturally occurring neurotransmitter acetylcholine. Acetylcholine and Nicotine have chemical similarities; these nicotinic acetylcholine receptors are located in the central nervous system and the nerve-muscle junction of skeleal muscles; whose activity increases heart rate, alertness, and faster reaction times. Nicotine acetylcholine stimulation is not directly addictiv. Dopamine is released in the process and this release of dopamine, which is associated with pleasure, is reinforcing and may also increase working memory.

There is also a fromation of acetaldehyde in tobacco smoke. This seems to play an important role in nicotine addiction; probably by fcilitating a dopamine release in the nucleus acumens as a response to nicotine stimuli.


Dangerous effect of tobacco

The World Health Organisation estimates that tobacco caused 5.4 million deaths in 2004 and 100 million deaths over the couse of 20th century. Similarly, the United States Center for Disease Control and Prevention describes tobacco use as "the single most important preventable risk to human health" in developed countries and an important cause of premature death worldwide.

Smoke contains several carcinogenic pyrolytic products that bind to DNA and cause many genetic mutations.

Use of tobbaco is a significant factor in miscrarriages among pregnant smokers, and also causes premature births, low birth weight and Sudden Infant Death Syndrome (SIDS).

Chemical contents of Cigrette smoke

Tobacco smoke contains over 4,000 different chemicals. At least 50 are known carcinogens (cause cancer in humans) and many are poisonous.

Poly nuclear aromatic hydro carbons - causing genetic mutation.

Acrolein - causing mutation in genetic copying process.

Lead-210, Polonium-201 - There are radioactive carcinogens.

Benzene (Petrol additive) - It is a known carcinogen and is associated with leukaemia.Chemical Contents of Cigrette Smoke

Formaldehyde (embalming fluid) - Known to cause cancer, respiratory, skin and gastrointestinal problems.

Ammonia (toilet cleaner) - Used as a dry cleaning fluid.

Acetone (Nail polish remover)- Fragrant volatile liquid ketone used as a solvent.

Tar - Particulate matter drawn into lungs when you inhale on a lighted cigrette. Once inhaled, smoke condenses and about 70 percent of the tar in the smoke is deposieted in the smoker's lungs.

Nicotine (Insecticide/addictive drug) - One of the most addictive substances known to man, a powerful and fast acting medical and non-medical poision. This is the chemical which causes addiction. Nicotine inhibits apoptosis, therefore accelerating existing cancers.

Carbon Monoxide (CO) - An odourless, tasteless and main poisonous gas in cigarette smoke.

TSNAs - Tobacco-specific N-nitrosamines (TSNAs) are known to be some of the most potent carcinogens present in smokeless tobacco, snuff and tobacco smoke.

Benzene - Benzene can be found in pesticide and gassoline. It is present in high levels in cigarette smoke and accounts for almost half of all human exposure to this hazardous chemical.

Pesticides - Pesticides are used on our lawns and gardens, which in being inhaled into our lungs through cigarette smoke.

Formaldehyde - Formaldehyde is a chemical used to preserve dead bodies, and is responsible for irritation of the nose, throat and eyes of somkers.

Effects of Smoking on Body

Effects of Smoking on BodyHair - Smoking may cause slow down hair growth, thinning and greying of hair.

Brain - Smoking affects the brain which is highly dangerous in later life. Blockage of the carotid artery may cut off the blood supply to the brain cells, which can lead to a stroke.

Nose - Smoking affects your nose and sense of smell may completely disappear.

Teeth and Gums : Smoking may cause staining of teath & gum bleeding. Loose teeth, gum diease and gingivitis are direct results of smoking.

Mouth and Throat : All cancers associated with the larynx, oral cavity and oesophagus are fatal smoking effects. The less dangerous smoking effects include a reduced sense of taste, sore throat and bad breath.

Hands : Poor blood circulation which leads to cold fingers, tar stained fingers, peripheral vascular disease and gangrene.

Lungs and Respiratory System : Lung cancer, cold and flu, pneumonia, asthma, cough, tuberculosis, chronic obstructive pulmonary disease, chronic bronchitis and emphysema are all harmful smoking effects. These probelms can seriously affect your health in later life.

Heart: An increased heart rate and a sharp rise in blood pressure are two immediate effects of smoking. Long term smoking efects include an increase in the blood cholesterol and fibrinogen level and increase the chances of Heart attack, Coronary heart desease, Aneurysm, Peripheral vascular disease, Strokes etc.

Digestive System : Smoking affects the body's digestive system and causes heartburn, peptic ulcers, Crohn's disease, gallstones and stomach cancer.

Skin : Wrinkles, premature ageing and scarring are just a few smoking effects which shows up on your skin.

Major Diseases caused by Smoking

Cancer -

90% of lung cancer cases happen due to smoking. Smoking may also lead to cancer of mouth, throat, bladder, pancreas, kidneys oesophagus and cervix.

Cardiovascular Diseases

Nicotine present in tobacco increases the cholesterol level in the blood. Cholesterol and other fats get deposited in the arteries, which cuases hardening of arteries. These arteries become narrow, rigid or blocked. Due to atherosclerosis (narrowing of arteries), blood clots are formed, which increases the risk of cardiovascular diseases. Common cardiovascular diseases found in smokers are coronary thrombosis, cerebral thromobosis, coronary heart diseases, blockage in the legs (peripheral vascular disease) and cerebro vascular diseases such as stroke.

  • Stroke risk is reduced to that of a non-smoker, 5-15 years after quitting
  • Risk of cancer of the mouth, throat and oesophagus is half that of a smoker.

10 Years

  • Lung cancer death rates are reduced double the time.
