MIND AND BODY: DRUGS
Man is the only animal that likes to take medicine but he brings the average very high. Arguments about this fact are usually of the all or none type. Dr. Oliver Wendell Holmes is frequently credited with saying, “If the whole materia medica could be sunk to the bottom of the sea it would be all the better for mankind – and all the worse for the fishes.” Dr. Holmes liked to give out smart sayings, but he was a clear thinker and an able physician and actually he carefully modified his statement. Before sinking the drugs he excluded opium and anesthetics and specifics: such things as quinine for malaria and mercury for syphilis and iodine for lack of thyroid secretion. Then he was willing to drop overboard most of the other things which could be useful but more often were harmful. At the present time he would not so dispose of antibiotics, although there is more and more evidence that as they are now they cause much trouble. Unfortunately a large proportion of the populace are not like Dr. Samuel Johnson, who said that he could be abstemious, but resemble him closely in their inability to be temperate.
One cardinal rule in taking drugs is that any, active enough to help out the body, are powerful enough to injure it. A poison is usually a comparatively large dose of a substance which in proper doses is helpful. Few things in nature have been more of a blessing to man than opium. Yet you all know that the normal person can be killed by it or ruined if he habituates himself to taking it in large doses. In some states cyanide gas is used to execute criminals. In small amounts cyanides are pleasing and harmless flavorings; almond, for instance.
A drug may have varying effects on different people. De Quincey said that opium stimulated him and I have seen that he was right. Barbiturates, which are delightfully quieting for most people, may at times cause a delirium, especial in the elderly. This change may develop fairly quickly in one who over a period of years has taken them infrequently but always with soothing effect. We get fairly well acquainted with the idiosyncrasies of the drugs which we have lived with for some time, but we never can be perfectly sure of the idiosyncrasies of the patients on whom they are used. The allergic reactions are examples of this. With the present-day enthusiasm for treatment and the extravagant publicity which every new drug and treatment gets as soon as it is announced, it is more and more necessary to counsel caution.
Fortunately some useful drugs cause, with large or long continued doses, such unpleasant symptoms that they have to be discontinued before they do serious harm. Digitalis, so valuable in certain heart conditions, irritates the stomach at times, causing nausea and vomiting, so that the patient cannot continue taking it any longer. Ipecac’s value is dependent on the nausea and vomiting it produces and must have been used much in the days when puking and purging were standard procedures. Many of you have doubtless experienced an excessive flow of saliva when you were nauseated. This increase of fluid is what makes ipecac in small amounts valuable as a cough medicine. The fluid increase occurs in the lungs, diluting the sticky secretions there and making them easier to cough up. I have a physician friend who has long had the foolish habit of tasting medicines. He sat at his desk one day advising mothers and occasionally sampling a bottle of syrup of ipecac. Later as he drove across the city he noticed that he was taking deep yawns. At his first place of call he leaned over to listen to a baby’s chest and suddenly all went black. You see, ipecac causes not only nausea, salivation, bronchial secretions, but also anemia of the brain. As many medicines are made up of a combination of drugs it ought to be evident to you that there are possibilities of many unpleasant effects when you dose yourselves.
