The decade of life at which the opium habit is most common is between

thirty and forty. But it may be developed at any age. Even infants are

not rarely made the subjects of chronic opium narcotism by the use of

soothing syrups and other poisonous nostrums.

Sex in itself exerts very little influence as a predisposing cause.

Owing to collateral circumstances, the number of women addicted to

opium is greater than the number of men. Kane[5] states that females

more frequently fall victims to these drugs than males, in the

proportion of three to one, and attributes this excess to the fact

that women more often than men are afflicted with diseases of a

nervous character in which narcotic remedies are used for long

periods. This observer suggests as an additional explanation the

occasional preference on the part of women for opium as a stimulant in

place of alcohol, its effects being less noticeable and degrading. On

the other hand, Levinstein observed in 110 cases 82 men and 28 women.

He does not, however, regard the conclusion that the use is more

common among men as warranted by these figures. The habit resulted in

these 110 cases from the following causes: In 20 men and 6 women after

acute affections; in 46 men and 17 women after chronic affections,

these diseases being in each instance accompanied by great pain. One

man began to use morphine as an antiaphrodisiac. Either to produce

mental excitement simply or to cause forgetfulness of the ordinary

cares of daily life, 15 men and 5 women indulged to an uncontrollable

extent.

[Footnote 5: _Drugs that Enslave_, Philadelphia, 1881. I refer with

pleasure to the early labors of this observer. His later publications

tell their own story.]

Occupation has in some respects much to do in favoring the development

of the opium habit. Familiarity with the use of drugs exerts a

powerful influence. Of Levinstein's 110 cases, 47 occurred in persons

belonging to the medical profession or dependent upon it; thus, 32

physicians, 8 wives of physicians, 1 son of a physician, 4 nurses, 1

midwife, and 1 student of medicine.

A predisposing influence of more importance than would at first sight

appear is found in sensational popular writings upon the subject. As

Kane has well said, “At the time in which De Quincey, Coleridge, and

Southey lived the people and the profession knew little of the opium

habit save among foreign nations. The habitués were few in number, and

consequently when De Quincey's article appeared it created a most

decided impression upon the popular mind—an impression not yet

effaced, and one which bore with it an incalculable amount of harm.

Men and women who had never heard of such a thing, stimulated by

curiosity, their minds filled with the vivid pictures of a state of

dreamy bliss and feeling of full content with the world and all about,

tried the experiment, and gradually wound themselves in the silken

meshes of the fascinating net, which only too soon proved too strong

to admit of breaking.” There can be no question that a percentage of

cases of the opium habit, small though it be, is even in our day to be

attributed to this cause.

Somewhat analogous in its etiological importance is the influence of

example upon persons of idle and luxurious habits. Nowhere in Western

countries, with the exception of the opium-smoking dens of the {651}

Chinese and their depraved associates, are there public places of

resort devoted to the practice of the opium and morphine habits, as

there are in Turkey and the East. According to Jouet—whose statements

are corroborated by occasional statements in French newspapers—the

habitual injection of morphine is to-day, in France at least, almost a

matter of fashion. Landowski states that friendship is occasionally

pushed to the extent of the exchange of pretty syringes in silver

cases as presents, and that a patient received upon his birthday a

hypodermic syringe as a present from his sister. Zambaco, whose

observations were made at Constantinople, states that among the

Moslems the opium habitués prefer the crude drug, either alone or

associated with certain aromatic substances, such as ambergris,

canella, or saffron, which are used for their aphrodisiac effect.

These mixtures are prepared openly in the family, and carried upon the

person in the form of pills in rich boxes of gold and enamel among the

better classes. This observer further says that the ladies of the

better classes carry jewelled cases containing hypodermic syringes and

artistic flaçons for the seductive solution, and that they avail

themselves of favorable opportunities to take an injection of morphine

even when together.

In addition to the predisposing influences already mentioned, it has

been customary to regard insanity as a cause of the opium habit.

Laehr[6] and Fidler[7] have gone so far as to class the morphine habit

among the psychoses. This view appears to be no longer tenable. The

opium habit must be classed with the taste for alcohol, gambling,

avarice, and lust as among human passions. That nervous subjects,

invalids, and individuals wanting in moral and physical tone are

specially prone to it is obvious. It constitutes in these cases,

however, an expression of the morbid constitution rather than a

substantive affection in itself. In the same manner, the opium habit

in insane persons must be looked upon as an epiphenomenon of the

morbid mental condition.

[Footnote 6: _Allgemeine Zeitschrift für Psychiatrie_, 1872.]

[Footnote 7: _Jahresb. der Gesellschaft für Natur und Heilkunde_,

Dresden, 1876.]

Levinstein has with reason insisted upon the essential difference

between the disturbances resulting from chronic poisoning by alcohol,

lead, arsenic, etc., and that produced by morphine. In the former

group the mental conditions are expressions of physical and chemical

alterations of the central nervous system, which, once established,

persist for an indefinite period, whereas in morphinomania the

troubles of the nervous system are chiefly functional and of a

transitory character. He regards the nervous disorders developed from

the prolonged use of morphine as the result simply of depression of

the nervous system, and the extreme suffering experienced on the

withdrawal of the regular dose to which the subject has been

accustomed as a trouble of innervation rather than as a psychical

derangement. This physical suffering and the mental depression which

accompanies it have their analogues in the angina occasionally seen in

paroxysmal affections of the heart, the blood-vessels, and the

respiratory organs. Certain it is that individuals addicted to opium

and morphine excesses in a high degree not only frequently retain full

possession of their intellect, but occasionally achieve and maintain

great distinction in professional and scientific life. Furthermore,

subjects of the opium habit, notwithstanding the gravest mental

disturbance manifested during the {652} continuance or upon the

cessation of the habit, usually exhibit when cured no further

indication of mental disorder.

_B_. The Exciting Cause.—In addition to the usual constituents of

vegetable substances, mucilage, albumen, proteids, fat, volatile

substances, and salts of ammonium, calcium, and magnesium, opium

contains a number of alkaloids, two neutral substances, and meconic

acid. Some of the alkaloids are probably derivatives from morphia. The

three most important alkaloids are morphine, codeine, and thebaine.

The neutral substances are meconin and meconiasin. Morphinæ

hydrochloras, acetas, and sulphas, codeina, and apomorphinæ

hydrochloras are officinal in the United States Pharmacopœia. Opium

and its alkaloids act principally on the central nervous system, and

in mammals on the brain. The functions of the nervous system, as

Brunton has pointed out, are abolished in the order of their

development, the highest centres being the first affected. In man the

action of opium is chiefly manifested upon the brain. With small doses

a stage of excitement, attended by increased activity of the

circulation, augmented nervous energy, and under favorable

circumstances an agreeable languor, followed by quiet sleep,

constitute the effects of the drug; with larger doses, of from one to

two grains, the transient stage of excitement is followed by deep

sleep, the awakening from which is marked by headache, nausea, and

evidences of gastro-intestinal catarrh; with still larger doses, of

three grains or more, deep sleep is produced, which speedily passes

into coma. The drug has an especial action on the vaso-motor system,

which is manifested in its power to diminish congestion and relieve

inflammation. With the exception of the urine and the sweat, the

secretions of the body are diminished by opium. The action of the drug

upon the intestines varies with the dose. In moderate doses it

diminishes peristalsis and causes constipation; in very small doses it

increases peristalsis; in large doses peristaltic action ceases.

Morphine is eliminated unchanged by the kidneys. It is eliminated also

by the gastro-intestinal mucous membrane, having been found in the

stomach after hypodermic injection. The action of opium and its

derivatives, as that of other narcotics, is much influenced by habit.

In those accustomed to the drug large (and sometimes enormous)

quantities are required to induce the characteristic manifestations.

Not rarely these manifestations are much retarded. The enormous amount

of two pints of tincture of opium has been taken in the course of a

day; a female patient afterward successfully treated by the writer

took habitually for a long period of time from ten to twelve grains of

morphine per diem, hypodermically. Diedriech[8] assumes that a portion

of the morphine introduced into the organism is converted into

oxydimorphine or other analogous substances which have the property of

counteracting to some extent the toxic effects of the morphine.

[Footnote 8: _Ueber oxydimorphine_, Inaug. Diss., Göttingen, 1883.]

Levinstein concludes as a result of experiments upon animals that

morphine, besides its influence upon the nervous system, exerts an

especial action upon two sets of organs: first, upon the digestive

tube; and second, upon the sudoriferous glands. Taken by the mouth, it

irritated the gastric mucous membrane. Whether taken by the mouth or

hypodermically, it diminishes the secretion of gastric juice and the

peristaltic movements of the intestine. These disturbances serve to

explain not {653} only certain of the phenomena of the opium habit

itself, but even more fully some of the symptoms manifested upon its

discontinuance. The nausea, vomiting, and constipation occurring

during the continuance of the habit must be looked upon as a result of

the derangement of function of the gastro-intestinal glandular

apparatus and the chronic catarrh which accompanies it. The abrupt

discontinuance of the drug is followed by the sudden return of

functional activity, hence salivation, persistent vomiting, anorexia,

and diarrhœa.

The effects of habitual excesses in opium and morphine upon the

nervous system are in essential particulars the same. Upon the

functions of the digestive system and upon nutrition they differ to a

considerable extent. Opium, as a rule, soon produces gastro-intestinal

derangements of a marked kind. These derangements consist in loss of

appetite, enfeebled digestion, nausea, vomiting, and constipation

alternating with occasional diarrhœa. The anorexia is usually

persistent and of a high degree, and has much to do with the

development of the wasting which is so common and so marked. The

occasional excessive appetite for food manifested by opium-eaters is

of brief duration. Its gratification aggravates the functional

disturbances, provokes gastro-intestinal catarrh, and thus tends to

increase the general malnutrition. On the other hand, morphine is much

better borne. At the present time almost all morphine habitués use the

hypodermic syringe, and, notwithstanding the elimination of the drug

in part by the gastric mucous membrane, thus escape in part its evil

effects upon the organs of digestion, and remain for a long time,

often despite enormous excesses, free from the nutritive disturbances

which are almost characteristic of the habitual abuse of crude opium.

SYMPTOMATOLOGY.—The symptoms of the confirmed opium habit may be

divided into two principal groups: first, the symptoms of chronic

opium- or morphine-poisoning; and second, the symptoms due to the

withdrawal of the drug.

I. Symptoms of Chronic Poisoning.—A considerable percentage of the

individuals addicted to the opium habit preserve for a longer or

shorter period of time the appearance of health; indeed, it is

possible for very large doses of opium to be occasionally taken by

certain individuals without appreciable impairment of the functions

either of the body or the mind. These cases must, however, be looked

upon as exceptional. It is estimated that from one-fourth to

three-tenths of the entire population of China are addicted to the

habit of opium-smoking. The statements of travellers concerning the

effect of this habit are somewhat conflicting. When practised within

bounds it appears to resemble in its effects the moderate use of

alcoholic stimulants, increasing the ability to endure fatigue and

diminishing for a time the necessity for food. In moderation it

appears to have little injurious effect upon the general health. On

the other hand, in the greater number of individuals the confirmed

opium habit causes in a variable period of time symptoms of the most

decided character; the appetite and general nutrition fail; emaciation

is often rapid, commonly marked, and sometimes extreme. There are

thirst and anorexia; a little later the patient begins to suffer from

nausea with occasional vomiting. At this time a loathing for food

alternates with boulimia. These occasional excesses in food are

followed by epigastric {654} distress, heartburn, and great mental

depression. The skin becomes relaxed, inelastic, and dull.

Exceptionally, especially in women who use morphine hypodermically,

embonpoint is preserved and the skin retains its normal tension and

appearance. The countenance is pale, muddy, and sometimes slightly

cyanotic. There is increased tendency to perspiration. Acne and

urticaria are common. Herpes zoster is encountered with considerable

frequency among opium subjects. In cases in which morphine is

administered by means of the hypodermic syringe the resulting lesions

of the skin are of importance. If the habit be concealed or denied,

they are of diagnostic value. Not rarely they constitute serious

affections in themselves. They are of all grades, from mere

inflammatory points to coarse infiltration and ulceration. The wounds

are frequently so thick set over the greater part of a limb as to

present the appearance of a continuous eruption. In other cases

scattered points of ulceration occur or extensive surfaces are

occupied by a series of ulcerations varying in size from a split pea

to an inch or more in diameter. Purulent inflammation of the

subcutaneous tissues, with burrowing, also occurs. Numerous scars bear

witness to the duration and extent of the habit. These lesions are

usually due to unclean needles and impure solutions; in certain cases

they are to be explained by the peculiarities of the individual as

regards the tendency to inflammation of the integumentary structures;

finally, instances are related in which immunity from skin lesions has

existed in spite of rusty needles and carelessly kept solutions.

The expression of the countenance is sometimes dull, much more

frequently furtive and timid. The repetition of the dose renders it

eager and bright. The pupils are commonly contracted, sometimes

enlarged, and occasionally unequal. Diminished power of accommodation

is common, and diplopia has been occasionally observed.

The action of the heart is often irregular and weak. Disturbances of

the vaso-motor system give rise to flushing of the face, irregular

sensations of heat over the body, and sweating. It is probable that

the albuminuria hereafter to be described is due to disturbance of the

circulation in the kidneys. The pulse is variable; it is sometimes

tense and full, sometimes small and thready, often irregular. The

volume, tension, and rhythm of the pulse depend largely upon the state

of the vaso-motor and general nervous systems. They vary according to

the periods of stimulation, following doses or the periods of

depression characterizing the intervals between the doses.

Palpitations occasionally occur. Respiration is, as a rule, normal.

Transient dyspnœa sometimes occurs after doses a little larger than

usual. Subacute bronchitis is common. The urine is often diminished in

quantity. Its specific gravity varies within extreme limits, being

influenced rather by collateral circumstances than by the dose of

opium or morphine consumed. In grave cases albuminuria occurs. Casts

of various kinds are also encountered. As Levinstein[9] has pointed

out, these changes in the urine are often transitory, disappearing

upon the suppression of the opium habit.

[Footnote 9: _La Morphiomanie_, 2d ed., Paris, 1880.]

In confirmed cases uric acid is increased and urea diminished. The

chlorides are also diminished in amount. Vesical irritation is

likewise common. It is apt to be accompanied by neuralgia of the

urethra and {655} of the rectum. Strangury and retention of urine also

occur in old cases. These complications are often followed by vesical

catarrh.

Derangements of the central nervous system are constant and serious.

The disorders which originally led to the use of opiates are in many

instances intensified. The temper is capricious, fanciful, and

discontented. There are giddiness, headache, and vertigo. Disturbed

sleep, irregular flying neuralgic pains, and hyperæsthesia also occur.

Spinal tenderness is occasionally encountered, with characteristic

painful spots. Reflex excitability is augmented, but in aggravated

cases the tendon reflexes are often impaired. Itching is common and

troublesome. It may be local or general. Trembling of the hands and of

the tongue also occurs. This tremor resembles in all particulars the

tremor of chronic alcoholism, and, as many individuals addicted to the

opium habit also abuse alcohol, it is not always easy to say to which

of these poisons the symptom in question is to be referred: it may be

due to their combined action. Disturbances of speech are not very

uncommon. Sleeplessness is troublesome, but absolute insomnia is rare.

The sleep which is obtained is late, irregular, and unrefreshing. In

several cases that have occurred under the observation of the writer

there has been habitual inability to sleep during the night, the

patients wandering about, occupying themselves in attempts to read or

write until toward morning, and then, under the influence of repeated

doses, falling into a more or less profound slumber, which has often

been prolonged till after midday. The effects of the dose upon the

mind are in the early periods of the habit agreeable exhilaration,

increased activity of imagination, and stimulation of the powers of

conversation. These effects are sometimes manifested for a long

period, and in many instances the most brilliant conversation, and

among professional men and public speakers the ablest efforts, have

followed the taking of large doses of opiates, and been followed in

turn by periods of the most profound physical and mental depression.

In the absence of the necessity for intellectual effort, and in

individuals incapable of it, the mental condition produced by the dose

is one of profound revery, largely influenced by the mental

organization of the subject. This state is described, and in many

particulars much exaggerated, in the writings of De Quincey,

Coleridge, and others.

The voluptuous play of the imagination ascribed to the action of the

drug by Orientals is for the most part absent among opium-takers in

this country. If present at all, it occurs only to a limited degree.

The corresponding fact is also worthy of note—namely, so long as the

habit is continued the depression between the doses is less profound

than that described as occurring in the East. One of the mental

peculiarities of individuals addicted to the opium habit is

secretiveness concerning their vice. Not infrequently, the real cause

of the grave derangements of health thus produced is wholly

unsuspected by the family or friends of the patient. When the habit is

suspected or admitted, the amount and frequency of the dose are rarely

fully known, patients almost invariably deceiving their friends in

regard to the particulars of their indulgence. Individuals above

reproach in other matters, and previously of unquestioned veracity,

lie without any hesitation in this matter. A patient under my care who

had secreted in her room a quantity of morphine when about to undergo

treatment, denied either having taken or then having {656} in her

possession any opium or morphine whatever, using the expression, “I

call God to witness that I neither now have, nor have had since I

began the treatment, any preparation of opium or morphine whatever.”

Within ten minutes sixty quarter-grain pills of morphine were

discovered secreted under the bolster. This patient was a devout,

refined, and, in regard to other matters, a trustworthy person.

The functions of the reproductive organs both in the male and in the

female are seriously deranged. In the male sex enfeeblement of the

sexual function is manifested in all degrees, even to complete loss of

sexual desire and sexual power. In certain individuals opium and

morphine in moderate doses produce some increase of sexual desire and

power, which is, however, speedily lost on the continuance of the

habit. Some doubt exists whether this is of psychical or physical

origin—a question at once difficult to decide by reason of the

reticence of opium-habitués upon this subject, and unimportant in

itself. Levinstein makes the interesting statement that in no cases

coming under his observation did the wives of morphomaniacs who had

injected as high as fifteen grains of morphine a day reach the full

term of pregnancy for two years prior to the treatment,

notwithstanding the fact that they were still young, that they had

borne children before their husbands had become addicted to morphine,

and that they had not, up to the time of the formation of the habit by

their husbands, suffered from premature accouchements.
