IN PRELIMINARY GROUP
The preliminary study of the 5 volunteer subjects had for its purpose the establishment of methods of procedures to be followed for the main group, and the obtaining of a general picture of the physical and mental effects induced by the drug. Having no knowledge of the safe limits of marihuana dosage, the dosage given to this group was restricted to from 1 to 4 cc. of the concentrate, and for smoking from 1 to 3 cigarettes.
When ingested, 1 cc. of marihuana was slightly effective, the multiples of this more so. There was noted in all subjects some increase in pulse rate and in blood pressure, dilated and sluggish pupils, dryness of the mouth and throat, ataxia, and some clumsiness and incoordination of movement. Symptoms distinctly disagreeable were dizziness in 3 subjects, a sense of heaviness of the extremities in 2, nausea in 2 and faintness in 2. Three showed motor restlessness. A state classed as euphoria, characterized by laughter, witticisms, loquaciousness, and lowering of inhibitions occurred in 3 subjects. This was not sustained but alternated with periods during which disagreeable symptoms were dominant. In one of the subjects (V.C.) there was no euphoric state, but a feeling of discomfort and depression throughout. Finally in one of the 5 (A.V.) with 2 cc. There was a state of depression with anxiety and with 4 cc. a psychotic episode with fear of death.
With the exception of the one individual during his psychotic episode, the subjects gave no evidence of abnormal mental content at any stage of the drug action, the only change noted being a delay in focusing attention on questions asked and difficulty in sustaining mental concentration. While there was objection at times to carrying out repetitious tests, there was no definite refusal. There was no sexual stimulation giving rise to overt expression.
With the cigarette smoking, ataxia and charges in the pulse rate, blood pressure, and pupils corresponded to those following oral administration. In only one of the subjects, however, was there definite euphoria. The common symptoms were dizziness and drowsiness. Two of the subjects found it difficult to concentrate.
The duration of the effects of marihuana was variable. When it was ingested, the effects usually passed off in from two to four hours, but in one instance persisted for seven hours and in another for fourteen hours. After smoking, the duration of effects was from one to three hours.
IN MAIN GROUP
The evidence of the effects of marihuana was obtained by the subject's statement of symptoms and sensations, by the nurses' reports and by the examiner's observations and interpretation of changes in the subject's mental state and behavior.
The dosage of the marihuana concentrate ranged from 2 to 22 cc. and in each subject the effects of more than one dose were studied. Dosage ranging from 2 to 5 cc. was used for the largest number of subjects, and that from 14 to 21 cc. on only seven occasions. It is known that marihuana intoxication may bring about a comatose state, but no attempt was made to determine the dosage required for this. The number receiving each of the selected doses is shown in Table 2.
While the duration of action and its intensity tended to increase with dosage, this was not always the case and equal doses did not bring about uniform effects in all those receiving them. Thus, 3 cc. produced a striking effect in one individual, much less in another in still another, 10 cc. produced less effect than S cc. Such variations are to be explained by differences in the mental make-up of the subject, and the particular state of his responsiveness at the time when marihuana is taken.
The number of cigarettes smoked ranged from one to eleven. The smoking of a single cigarette took about ten minutes and up to eight could be smoked in an hour. In smoking, increasing the number of cigarettes usually increased the sensation described as "high," but here also there was no uniformity in individuals or groups.
When marihuana was ingested, in dosages from 2 cc. up, its actions became evident in from one half to one hour. The maximum effects were seen in from two to three hours. These subsided gradually, but the time of disappearance was variable, usually three to five hours, in some instances twelve hours or more.
When marihuana cigarettes were used the effects appeared almost immediately. After one cigarette, these had usually disappeared in an hour. After several cigarettes had been smoked the effects increased progressively in intensity and reached a maximum in about an hour. In most instances they disappeared in from three or four hours.
The effects on the general behavior of the subjects taking the concentrate were variable. If left undisturbed some remained quietly sitting or lying, showing little interest in their surroundings. Others were restless and talkative. Under the heading "Euphoria" there are listed those marihuana effects which give rise to pleasurable sensations or experiences. These are a sense of well-being and contentment cheerfulness and gaiety, talkativeness, bursts of singing and dancing, daydreaming, a pleasant drowsiness, joking, and performing amusing antics. The drowsiness, daydreaming and unawareness of surroundings were present when the subject was left alone. Other euphoric expressions required an audience and there was much contagiousness of laughing and joking where several of the subjects under marihuana were congregated. The occurrence of a euphoric state, in one or another form, was noted in most of the subjects. But except for those who were allowed to pass the time undisturbed, the pleasurable effects were interrupted from time to time by disagreeable sensations.
Quite commonly seen, as with the preliminary group, was a difficulty in focusing and sustaining mental concentration. Thus, there would occur a delay in the subject's answers to questions and at times some confusion as to their meaning. There was, however, except in a few isolated instances, no abnormal mental content evident and the responses brought out by the examiner were not different from those in the pre-marihuana state.
Altered mental behavior which would give rise to more concern was seen in a relatively small number of subjects. In some this took the form of irritation at questioning, refusal to comply with simple requests and antagonism to certain of the examiners. There was, however, only verbal and no active opposition in any of these behaviors, caused by the subject's desire to be left undisturbed and his disinclination to carry out certain tests which in his pre-marihuana period he had considered tiresome and meaningless. With this came antipathy to those conducting the tests.
The occurrence of the disagreeable physical symptoms accompanying marihuana action would naturally lead to a feeling of disquietude and some alarm as to significance and consequences.
This, however, was a prominent feature in relatively few instances. A pronounced state of anxiety reaching a panic stage, associated usually with fear of death or of insanity, was observed only in those subjects experiencing psychotic episodes and here the anxiety state led to pleas for escape and not to acts of aggression. Even in the psychotic states there were no uncontrollable outbursts of rage or acts of violence.
Some evidence of eroticism was reported in about 10 per cent of the 150 instances in which marihuana was administered to the group. The presence of nurses, attendants and other women associated with the study gave opportunity for frank expression of sexual stimulation, had this been marked. There was no such expression even during the psychotic episodes.
In some isolated instances there was evidence of marked lowering of inhibitions such as loud discharge of flatus, urinating on the floor instead of in the vessels supplied, and in one instance frank exhibitionism. In the last instance the subject, who was not a regular marihuana user, had been arrested on three occasions for indecent exposure.
The frequency with which significant changes in behavior occurred is indicated in Table 3
As used in Table 3, anxiety means the subject's expressed worry concerning what might happen to him. Excitement, shown by physical restlessness, muscular twitchings and jerky movements, and loud talking, and some degree of antagonism are known to be expressions of an "alarm" or "fear" state.
It is seen from this table that, except for euphoria, the effect of marihuana was definitely more pronounced on the nonusers. This might be taken as evidence of a persisting tolerance to the drug in the user group, but, on the other hand, it may have as its basis a feeling of greater apprehension in the nonusers. Such a feeling would undoubtedly arise among those who have had no previous experience with marihuana and are in a state of uncertainty as to its possible harmful effects.
Of the subjective symptoms, a feeling described as lightness, heaviness, or pressure in the head, often with dizziness, was one of the earliest and occurred in practically all subjects, irrespective of dose. Dryness of the mouth and throat were reported by over half of the subjects as was also a floating sensation. Unsteadiness in movement and a feeling of heaviness in the extremities were commonly experienced as was a feeling of hunger and a desire for sweets especially. Less commonly noted were nausea, vomiting, sensations of warmth of the head or body, burning of the eyes and blurring of vision, tightness of the chest, cardiac palpitation, ringing or pressure in the ears, and an urge to urinate or defecate.
From observation by the examiner, tremor and ataxia were present in varying degrees in practically all instances and in all dosages used, as were also dilatation of the pupils and sluggish response to light.
These effects were often present on the day following marihuana administration.
The frequency of the more common subjective symptoms and their relation to dosage is shown in Table 4. The figures are taken from the subject's reports.
There is a tendency for the symptoms to be more frequent in the non-users than in the users but the differences are variable and in general not striking.
The Marihuana Cigarette
(Look for the Jack Benny Jello Hour)
Smoking. When marihuana is smoked, there is, as has been stated, no such accuracy in dosage as is the case when it is ingested. The marihuana user acquires a technique or art in smoking "reefers." This involves special preparation of the cigarette and regulation of the frequency and depth of inhalations. In a group of smokers, a cigarette circulates from one to another, each in turn taking one or more puffs. The performance is a slow and deliberate one and the cigarette, held in a forked match stick, is smoked to its end.
When the smoke comes in contact with the respiratory mucous membrane, the absorption of the active principle is rapid and the effects are recognized promptly by the subject. He soon learns to distinguish the amount of smoking which will give pleasant effects from the amount which will give unpleasant ones and so regulates his dosages. Providing there are no disturbing factors, as is the case in gatherings of small friendly groups or parties in "tea-pads," the regulated smoking produces a euphoric state, which accounts for continued indulgence.
The effect from smoking marihuana cigarettes was studied in 32 subjects. Of these, 20 were classed as users, that is, prior to their arrest they had had more or less extensive experience in smoking. In the study the smoking was repeated by each subject several times, the number of cigarettes smoked within an hour ranging from one to eight.
In all of the user group the smoking produced a euphoric state with its feeling of well- being, contentment, sociability, mental and physical relaxation, which usually ended in a feeling of drowsiness. Talkativeness and laughing and the sensation of floating in the air were common occurrences. These effects were of short duration, from one to three or four hours after the smoking was concluded. In none of these subjects was there an expression of antagonism or antisocial behavior.
In the non-user group the effects were similar except that in one subject a state of mental confusion occurred and in another the main effect was a feeling of dizziness, unsteadiness, and muscular weakness. Finally one subject showed effects entirely different from the others. He smoked one cigarette and became restless, agitated, dizzy, fearful of his surroundings, afraid of death. He had three short attacks of unconsciousness. At one period he had visions of angels, and for a few minutes a euphoric state. The entire episode lasted a little over an hour, after which he went to sleep. This subject had a similar psychotic episode after taking 120 mg. of tetrahydrocannabinol. On seven other occasions he had been given the marihuana concentrate or tetrahydrocannabinol with no unusual effects.
Of the physical symptoms occurring with smoking, dryness of the mouth and throat, dizziness, and a sensation of hunger were the most common. None of these or other symptoms seemed to lessen materially the pleasurable effects.
The effect of smoking on the 7 females, 6 of whom were classed as users, corresponded to that on the male group. All showed euphoric effects. One of the subjects was nauseated and another was restless, irritable, and contrary. These effects were observed in both of the subjects when marihuana was taken by stomach. One of the users, euphoric after smoking 6 and 10 cigarettes, had a psychotic episode after 8 cc. of marihuana concentrate.
Tea-Pad Parties. (This section on "Tea-Pad Parties" was prepared by Mrs. Halpern.) In addition to the quantitative data regularly obtained from the subject during the course of the testing program, the examiner had opportunity to make diverse observations of the subject's global reactions, which threw interesting light on the general effect of the drug on the individual personality.
When the subject became "high," his inclination was to laugh, talk, sing, listen to music, or sleep, but the requirement that he solve problems, answer questions, or remember drawings created an artificial situation, tending to bring him "down" and spoil his pleasure. In order, therefore, that the influence of the drug might be observed in less formal circumstances and in a set-up more nearly like the customary "tea-pad," two groups of men were given "parties" on the last night of their hospital sojourn. The men were consulted beforehand, and the stage was set according to their desires. They requested that nothing be done until it was really dark outside. They brought the radio into the room where the smoking took place and turned it to soft dance music. Only one shaded light burned, leaving the greater part of the room shadowy. The suggestion was made that easy chairs or floor cushions be procured but the party progressed without these.
The men were allowed as many cigarettes as they wanted. When the "reefers" were passed out they crowded around with their hands outstretched like little children begging for candy. The number of cigarettes the men smoked varied, the range being from two to twelve or thirteen. There were both users and non-users in these two groups. The users of course were highly elated at the prospect of getting much free "tea," and some of the non-users also smoked with genuine enjoyment.
In the beginning the men broke up into little groups of twos and threes to do their smoking, or in some instances went off by themselves. Smoke soon filled the atmosphere and added to the general shadowy effect. After the initial smoking there was some moving about- some men laughed and joked, some became argumentative, while some just stared out of the window. The arguments never seemed to get anywhere, although they often dealt with important problems, and the illogical reasoning used was never recognized or refuted by the person to whom it was addressed. Gradually, as though attracted by some force, all restlessness and activity ceased, and the men sat in a circle about the radio.
Occasionally they whispered to one another, laughed a little, or swayed to the music, but in general they relaxed quietly in their chairs. A feeling of contentment seemed to pervade, and when one man suddenly got a "laughing jag" they were annoyed at the interruption.
In general, they gave the impression of adolescent boys doing something which was forbidden and thereby adding spice to the indulgence. Many of the adolescent personality patterns as they appear in group activities were clearly observable here. There was the eternal "wisecracker," the domineering "important" individual who tried to tell everyone what to do, the silly, giggling adolescent and the shy, withdrawn introvert. One forgot that these were actually adults with all the usual adult responsibilities. One could not help drawing the conclusion that they too had forgotten this for the time being.
Although urged to smoke more, no subject could be persuaded to take more than he knew or felt he could handle. After about an hour and half of smoking, the men were given coffee and bread and jam and the party broke up. They all went to bed and reported the next day that they had slept very well.
Another attempt at evaluating the effect of marihuana in less formal situations was made in the following manner. The examiner, one of the police officers and the subjects listened to Jack Benny on the Jello Program at 7 o'clock Sunday evening. The police officer noted the number of times the audience laughed, and the length of time the laughter lasted. The examiner checked these items for the subjects. The first time this was done without marihuana; the following week the subjects were given several "reefers" about fifteen minutes before the radio program started. The results were as follows:
Without drug, the subjects laughed 42 times as against 72 laughs in the radio audience. The total time for all laughs was 63 seconds as compared with 139 seconds for the radio audience. With cigarettes the subjects laughed 43 times as compared with 47 laughs in the audience, the total laugh time being 129 seconds as compared with 173 seconds of laughter in the audience. Without drug, the subjects laughed, roughly speaking, only half as often and as long as the audience- while under the drug they laughed almost as often and the laugh time was about 75 per cent that of the audience.
It is obvious that under marihuana the subject laughs more readily and for longer time intervals. This is probably due both to the fact that things seem funnier to him and because when under the influence of the drug he is less inhibited.
Differences Between Concentrate and Cigarette
When marihuana was ingested, it was in the form of the concentrate, containing all the active principles which are soluble in the medium used. The relative proportions of the principles present are unknown, and the effects can be assumed to give a composite picture of different actions, the dominating one being that of tetrahydrocannabinol. There is no information available concerning the principles present in marihuana smoke, and it is possible that some of those found in the concentrate have been destroyed by the heat of combustion. The effects from smoking correspond to those induced by tetrahydrocannabinol taken by stomach, so it may be assumed that this principle is present in the smoke. The rapidity with which effects occur after smoking demonstrates the quick absorption of the cannabinol from the respiratory tract and the short duration of these effects indicates its prompt excretion or detoxification. When the concentrate is taken, the absorption from the intestinal tract is slower and more prolonged. For these reasons it is not possible to make a precise comparison between the effects of the two forms of administration.
In general the subject's consciousness of unpleasant symptoms is more marked when the concentrate is taken and this may interrupt or obscure the pleasant effects. The long duration of action and the inability of the subject to stop it serve to accentuate the physical symptoms and to cause apprehension concerning what may happen.
The result of all this readily accounts for the irritability, negativism and antagonism occurring. The lessening of inhibitions is not peculiar to marihuana, for in a few subjects who were given alcohol in intoxicating doses the behavior corresponded to that induced by marihuana.
After smoking the main effect was of a euphoric type. Some dizziness and dryness of the mouth were generally present but were not pronounced enough to distract from the pleasant sensations. The condition described as "high" came on promptly and increased with the number of cigarettes smoked, but it was not alarming or definitely disagreeable, and did not give rise to antisocial behavior.
On the contrary it prompted sociability. The marihuana was under the subject's control, and once the euphoric state was present, which might come from only one cigarette, he had no inclination to increase it by more smoking. When a considerable number of cigarettes were smoked, the effect was usually one of drowsiness and fatigue.
The description of the "tea-pad parties" brings out clearly the convivial effect on the groups and the absence of any rough or antagonistic behavior.
What has been referred to as psychotic episodes occurred in 9 subjects, 7 men and 2 women. A description of the happenings in each instance is given. (2)
(2) Throughout this section fictitious initials are used to avoid any disclosure of the subjects' identities.
A.V. Male. Non-user. Given 4 cc. of marihuana concentrate. About three hours later he became restless, tremulous, agitated, fearful of harmful effects, suspicious of examiners. For short periods he was euphoric. At one time he had visual hallucinations of figures making gestures suggesting harm. He talked continuously, mainly expressing fear. His answers to questions were delayed but intelligent.
W.P. Male. Occasional user. Given 3 cc., repeated two hours later. At first there was a euphoric state; later he became resistant and negativistic. He showed antagonism to the examiner, demanding to be left alone. He vomited twice. Throughout he was highly excited and talked to himself. The effects in general resembled those seen in a maniacal state. He returned to his normal state in about three hours after the second dose.
F.D. Male. Occasional user. Given 4 cc. Five hours later he became confused, disoriented and slow in answering questions. There were periods of elation and depression with laughter and weeping. The effects passed off in six hours.
R.W. Male. Non-user. Given 5 cc. Three hours later he became disoriented with continued talkativeness and rapid shifting of thought. He had fits of laughter and weeping, grandiose ideas, some paranoid trends. He answered questions clearly but without perseveration. He returned to normal after six hours.
I.N. Female. Occasional user. Also heroin addict for many years. Given 8 cc. Three hours later she became confused and anxious with periods of laughing and weeping. There were several short episodes resembling hysterical attacks and dyspnea, pallor and rapid pulse during which she felt that she was dying and screamed for the doctor and for a priest. Throughout, her response to questioning was intelligent but delayed. There was a return to her normal state in three hours.
E.C. Male. Non-user. Given 6 cc. Two hours later he developed a marked state of anxiety accompanied by a sensation of difficulty in breathing. This began during a basal metabolism test. In the Sanborn equipment used there is a nose clip occluding nasal breathing and a rubber mouthpiece through which the air is inspired and expired. During the test the subject became confused, panicky and disoriented as to time. The anxiety over breathing continued for four hours but could be interrupted by distraction. He was then given 4 cc. more. The breathing difficulty lasted five hours more. The condition here had features seen in claustrophobia. Before the episode, the subject had taken marihuana on five occasions in 2, 4, 5, 5, and 2 cc. dosage, without any symptoms of respiratory distress. However, after the episode he took marihuana on three occasions in 2, 5, and 6 cc. dosage and each time the respiratory symptoms occurred. A certain degree of nervousness was present but there was no mental confusion. The subject realized that there was no physical obstruction to his breathing and had learned that by concentrating his thought on other lines he could keep his respiratory difficulties in abeyance and would not suffer from real anxiety. Smoking up to as many as thirteen marihuana cigarettes did not bring about the respiratory effect. It appeared then that the respiratory symptoms were precipitated by the wearing of the apparatus while under the influence of marihuana, and through suggestibility there resulted a conditioning to the marihuana concentrate which was given subsequently.
The description of these six psychotic episodes fits in with many others found in marihuana literature. They are examples of acute marihuana intoxication in susceptible individuals which comes on shortly after the drug has been taken and persists for several hours.
The main features of the poisoning are the restlessness and mental excitement of a delirious nature with intermittent periods of euphoric and an overhanging state of anxiety and dread.
Three other subjects presented the features of marihuana psychosis.
R.H. Male. White. Age 23. Non-user. In prison for the offense of living on prostitution. The family history was bad. His father never supported his wife or family and there was continual discord at home. When the subject was 9 years old the father deserted the family. Three brothers received court sentences, one for stealing a taxi, one for rape, and one for striking a teacher. R.H. was a problem child at school and on account of truancy and waywardness he was sent to the Flushing Parental School.
He ran away from this school several times and was transferred to the House of Refuge on Randall's Island. At the age of 16 he was discharged. Since that time he had had two jobs, one for three months in a factory, the other for four and one-half months in the W.P.A. When he was 16 he was run over by a truck and was unconscious for a time. After his return to the Riker's Island Penitentiary from Welfare Hospital further questioning concerning his past revealed that he was subject to "fits" occurring once or twice every two months. During the attacks his body became rigid and his mouth felt stiff.
The subject was admitted to Welfare Hospital for the marihuana study on February 20th. After the usual program of examinations he was given 2 cc. of the concentrate on February 27th and February 28th. These doses brought on the symptoms of dizziness and tremor and heaviness of the head and the state called "high" which is characterized by periods of laughter and talkativeness. These effects passed off in a few hours and were followed by drowsiness and a sense of fatigue. On March 1st at 1 p.m. he smoked one marihuana cigarette. Immediately afterwards he became agitated and restless and suddenly lost consciousness. He recovered quickly and stated that he had had visions of angels and had heard choirs singing. Later he had a second short period of unconsciousness. During the afternoon he continued to be agitated and restless and had periods of laughing and weeping. After he was given phenobarbital he went to sleep. On the next day his only complaint was that he felt dizzy. Following this episode he was given 4 cc. Of marihuana concentrate on March 3rd and 2 cc. on March 10th and 2 cc. of tetrahydrocannabinol on March 5th and 4 cc. on March 8th. The effects corresponded to those seen after the earlier administrations of 2 cc. doses of the concentrate.
On March 11th R.H. was given 5 cc. (75 mg.) of the tetrahydrocannabinol at 11 a.m. and 3 cc. at 2 p.m. No unusual effects were noted during the afternoon and he ate his supper with appetite at 4:30 p.m. At 6 p.m. he became restless, apprehensive and somewhat belligerent. He felt that something had happened to his mother, that everybody was acting queerly and picking on him. He continued to be agitated and fearful, refused medication and slept poorly. This condition persisted and on March 13th he was returned to Riker's Island. After four days there he became quiet and composed. The psychotic state cleared up completely. The resident psychiatrist's report was: Impression 1. Psychosis due to drugs. (Marihuana experimentally administered.) Acute delirium, recovered. 2. Convulsive disorder, idiopathic epilepsy. Petit mal on history.
H.W. Female. White. Age 28. Non-user. Drug peddler, serving three years' indefinite sentence for unlawfully possessing a drug. Her parents died when she was about 10 years old and she was raised in an orphanage. At the age of 19 she entered a training school for nurses, but gave this up after four months and supported herself by prostitution. Her sister and her sister's husband were drug addicts and through them she began taking morphine and heroin, being, according to her account, depressed and dissatisfied at the time. She continued using these drugs up to the time of her arrest, a period of eight years. In 1938 she married a man who was also a drug addict, and engaged in the drug traffic.
On May 7th she was given 2 cc. of marihuana. Aside from a headache and a feeling of muscular weakness and uncoordination, the effect was to make the subject feel gay and very good-natured On May 8th she was given 3 cc. Of the concentrate and became somewhat confused and unsteady, irritated and upset at carrying out tests, and greatly worried about the physical symptoms. Five hours after she had taken the drug the effects had largely passed off. Six hours later, however, she became restless and agitated, moving about constantly, and worried about past conduct. This state continued for a few hours. On other occasions the subject was given marihuana in doses of 2, 3, and 4 cc. Twice after the administration of 3 cc. The general effect was of a euphoric type, and after 4 cc. Had been given a state of sadness set in on two occasions and one of euphoria on a third. Toward the end of her stay the subject became depressed and moody, constantly dwelling on the belief that she had committed unpardonable sins.
She was returned to the House of Detention on June 2nd, transferred to the Psychiatric Division of Bellevue Hospital on June 9th, and from there was sent to Matteawan State Hospital on July 10th. On admission to the State Hospital she appeared confused, retarded, apprehensive, and depressed. She had a marked feeling of guilt. She began to improve in September and was discharged, cured, in January. Since her return to New York she reports at frequent intervals to the parole officer. She has secured employment in a food shop and is to be promoted to the position of manager of the shop.
The diagnosis made at the State Hospital was: Psychosis, due to drugs and other exogenous poisons (morphine and heroin).
D.P. Male. Colored. Age 23. Occasional user. Sentenced for unlawful possession of drugs. Since graduation from high school at the age of 16 he had had no occupation. His criminal record dated from his graduation. He was arrested in 1934 for disorderly conduct and in the same year sentenced to Elmira Reformatory for five years for second-degree assault. He was paroled in 1936, but during the same and the following year was arrested three times for assault or robbery. He was returned to Elmira where he remained until his discharge in 1940. In August 1940 he was arrested for the possession of drugs and sentenced to a three-year indefinite term. He had served eight months of this sentence when he was admitted to Welfare Hospital as a subject for the marihuana study.
During his stay at Welfare Hospital, D.P. was given marihuana in the form of a concentrate and as cigarettes on numerous occasions. His symptoms and behavior corresponded to those usually seen, lasting a few hours with no after-effects. When the time came for his return to Riker's Island he urged that he be allowed to stay at the hospital and assist in the study. Two weeks after his return to the penitentiary he developed a psychosis characteristic of schizophrenia. He was transferred to Matteawan where the diagnosis made was: Psychosis with psychopathic personality.
These three cases are of special interest from the standpoint of the relationship of marihuana to the psychosis. The first subject, R.H., had a definite history of epileptic attacks. After smoking one marihuana cigarette he experienced an acute confusional state which lasted a few hours. In the second episode which lasted six days there was a more prolonged confusional state. Epileptics are subject to such attacks, epileptic or epileptic equivalents, which may be brought on by any number of upsetting circumstances. In this case marihuana is the only known factor which precipitated the attack.
The second subject, H.W., was a heroin addict of long standing. During her stay in the hospital, in her retrospective reports on her marihuana experiences there were usually included expressions of worry and remorse at her failure to answer questions or perform tests honestly, informing on the other women in her group, and denials concerning a syphilitic infection she thought she had had. Prior to this incarceration she had had no prison experience. The mental picture developed from the study at the hospital and at Matteawan and the subject's subsequent history represent a fairly typical example of what is termed a prison psychosis.
The third subject, D.P., did not develop his psychosis until two weeks after he had been returned to the Riker's Island Penitentiary. He had shown no unexpected effects from marihuana and had hoped to be allowed to stay on at the hospital instead of going back to prison to complete more than two years of an unexpired sentence. At Matteawan this subject was considered to have an underlying psychopathic personality. His case also may be taken as an example of prison psychosis. With both the second and third subjects, the exact role of marihuana in relation to the psychosis cannot be stated.
Dr. Peter F. Amoroso, Commissioner of Correction of the city of New York, has given us information concerning the prisoners sentenced to the penitentiary at Riker's Island from whom our subjects were drawn. During the year beginning July 1, 1941, and ending June 30, 1942, there were 1,756 inmates in this institution. They had received an indeterminate sentence, that is, from a minimum of a few months to a maximum of three years. Of this group, 175 were subjected to intensive study by the psychiatrist because they were considered possible psychotic cases, 117 were sex offenders, and 200 were miscellaneous cases referred for mental observation, making a total of 492. Twenty-seven of these cases were committed to state institutions for the criminal insane, namely, 25 to Matteawan and 2 to Dannemora.
Commissioner Amoroso, after reviewing these cases, writes as follows:
"The prison atmosphere may place a most severe strain on those who are physically or mentally abnormal upon commitment . . . Emotionally unstable persons find themselves during incarceration denied the assertion and enjoyment of the basic human urges and impulses and it is natural to expect, therefore, that prison life may result in various types of explosions, such as psychoses, neuroses, sex perversion, and even physical and moral deterioration.'
"I am indeed surprised that we had so little trouble with our volunteers upon completion of their study and sojourn at Welfare Hospital, and the few psychotic episodes that occurred are exactly what we would expect in the whole group without considering the administration and effects of excessive doses of marihuana."
In the study of the actions of marihuana in respect to subjective and objective symptoms and behavior, the marihuana was given a number of times to each of the subjects in the form of the concentrate taken by stomach. The amount given ranged from 2 to 22 cc., in most cases from 2 to 5 cc. After marihuana was taken, the systematic action became evident in from one- half to one hour and the maximum effects were seen in from two to three hours. They passed off gradually, usually in from three to five hours, although in some instances they did not completely disappear until twelve or more hours.
Of the symptoms occurring, a feeling of lightness in the head with some dizziness, a sensation of floating in the air, dryness of the throat, hunger and thirst, unsteadiness and heaviness in the extremities were the most frequent. Tremor and ataxia, dilation of the pupils and sluggishness in responsiveness to light were observed in all subjects.
From observations on the behavior and responses of the subjects, it was found that a mixture of euphoria and apprehension was generally present. If the subjects were undisturbed there was a state of quiet and drowsiness, and unawareness of surroundings, with some difficulty in focusing and sustaining mental concentration. If they were in company, restlessness, talkativeness, laughter and joking were commonly seen. A feeling of apprehension, based on uncertainty regarding the possible effects of the drug and strengthened by any disagreeable sensations present, alternated with the euphoria. If the apprehension developed into a state of real anxiety, a spirit of antagonism was shown. However, any resistance to requests made to the subjects was passive and not physical and there was no aggressiveness or violent behavior observed. Erotic ideas or sensations when present took no active expression.
Six of the subjects developed toxic episodes characteristic of acute marihuana intoxication. The dosage varied from 4 to 8 cc. of the concentrate, and the episodes lasted from three to six hours, in one instance ten hours. The effects were mixtures of euphoric and anxiety states, laughter, elation, excitement, disorientation and mental confusion.
The doses given were toxic to the individuals in question but not to others taking the same or larger ones. Once the drug had been taken the effects were beyond the subject's control. The actions described took unusual expression because for the particular subject at a particular time the dose was unusually effective. A corresponding toxicity did not occur from cigarettes for here the effects came on promptly and on the appearance of any untoward effects, the smoking was stopped.
In three of the subjects a definite psychotic state occurred, in two shortly after marihuana ingestion, in one after a two week interval. Of the first two, one was an epileptic and the other had a history of heroin addiction and a prepsychotic personality. The third was considered a case of prison psychosis. The conclusion seems warranted that given the potential personality make-up and the right time and environment, marihuana may bring on a true psychotic state.
