Tobacco addiction:

Tobacco has been used by humans for more than 400 years

• It is smoked, chewed or snuffed.

• Tobacco contains large number of chemical substances including nicotine (an alkaloid).

• Nicotine stimulates adrenal gland to release adrenaline and nor-adrenaline into blood circulation, both of which increase blood pressure and heart rate.

• Tobacco chewing is associated with increased risk of oral cancer.

• Smoking increases carbon monoxide (CO) content in blood and reduces the concentration of haembound oxygen so it causes oxygen deficiency in body and is associated with increased incidence of cancer of lungs, urinary bladder and throat, bronchitis, emphysema, coronary heart diseases, gastric ulcer etc.

• Smoking is very prevalent in society, both among youth and the old. There is a need to spread awareness about its addictive nature and addicts must be given proper medical help and counselling. The cigarette packing also carries a warning "Smoking is injurious to health".
