Inimical Interaction of Tobacco with Drugs

Consumption of tobacco in any form is bad as it has inimical interaction with a majority of drugs/medicines in addition to its other bad effects and health hazards. There are thousands of chemical substances in the tobacco and the smoke of its products like cigarette and bidi. Nicotine, tar and carbon monoxide are three most damaging chemical substances present in the smoke of cigarette and bidi. Smoking and chewing of tobacco would affect your metabolism and physiology. Like cocaine and morphine; nicotine causes addiction to tobacco. Cigarette smoking speeds up your heart beat and increases blood pressure. It is major cause of emphysema (chronic obstructive lung disease leading to damage of alveoli), chronic bronchitis, coronary heart disease (CHD) and lung cancer. Carbon monoxide along with nicotine increases the prevalence of heart attack in smokers.

The tar present in the smoke of cigarette or bidi damages the delicate epithelial lining of lungs. The brown and sticky deposit produced by the tar is a cause of lung cancer in smokers. The nicotine content per cigarette has been estimated to 20-30 mg. The carbon monoxide remains in the blood of a smoker for 5-6 hours after he finishes a cigarette and keeps interacting with body metabolites and drugs. The tobacco that is chewed, kept in the mouth or snuffed has equally bad effects. The consumption of tobacco is like ‘slow motion suicide’ due to its bad effects and inimical interaction with large number of drugs taken for various health ailments:


Tobacco has been found to reduce the effectiveness of pain killers (analgesics), anti-asthma drugs, anti-coagulants and drugs used to treat heart ailments. The risk of cardiovascular diseases increases in women taking oral contraceptives.
