La educación ambiental para la conservación de la vida silvestre

LA EDUCACION AMBIENTAL Y CONSERVACION DE LA VIDA SILVESTRE

La conservación de la vida silvestre es un aspecto del problema ambiental que requiere la especial atención de todos los seres humanos de este planeta (Morales, 1998). La vida silvestre es un recurso valioso de los pueblos, constituyendo un recurso para la investigación y la recreación.

El manejo y conservación de la fauna silvestre incluye cuatro aspectos importantes: investigación, ecología y manejo, legislación, cumplimiento, educación y participación (Jacobson, 1995) La educación a todos los niveles debe ser desarrollada para el conocimiento de las interrelaciones entre los humanos y el ambiente, ya que es fundamental encontrar soluciones viables para el manejo y conservación de la vida silvestre y del medio ambiente en general (Millán, 1998).

La vida silvestre en Latinoamérica ha estado sometida durante las últimas cinco décadas a un uso intensivo, sin métodos de conservación y manejo establecidos. La sobrexplotación de especies de plantas y de animales a llevado al borde de la extinción a muchos de estos. La destrucción de hábitat, la colonización descontrolada y la contaminación ambiental han aumentado el riesgo de extinción de muchas especies. Por lo tanto, si se realizan esfuerzos educativos que muestren los efectos negativos que estos factores producen, podemos ayudar a restaurar el ambiente y las especies que lo conforman.

Existen ejemplos de esfuerzos educativos a nivel mundial, sobre el uso de diversas especies de animales muy amenazados para levantar conciencia sobre los graves problemas ambientales que confronta el planeta. En diversos países se han seleccionado especies banderas como estrategias de educación ambiental para la conservación de la biodiversidad local. Una especie bandera es aquella cuya conservación in situ resulta en la conservación de un número significativo de otras especies y el mantenimiento de los ecosistemas naturales en buen estado de funcionamiento.

Estas medidas educativas han sido un fuerte insumo a la conservación mundial del ambiente. Dentro de los ejemplos que podemos mencionar tenemos: la campaña para salvar el oso panda en China, los gorilas de la niebla en Kenia, el rinoceronte negro y los chimpancés africanos, el lince español, la cotorra puertoriqueña, la cotorra margariteña, el pufín canadiense, el búfalo norteamericano, el lobo mejicano, el mono aullador beliceño, la guacamaya verde y roja y el mono tití de Costa Rica, la chinchilla chilena, y el mono tití rosado de Brasil, etc.

Este último caso del mono tití rosado (Leontopithecus rosalia) de Brasil ejemplifica un esfuerzo de casi veinte años de programas de educación ambiental desarrollados con la finalidad de conservar la especie en si y los hábitat y ecosistemas de los cuales es parte. La situación crítica a la que llegó esta especie se debió principalmente a la destrucción de sus hábitat, debido que los ciudadanos residentes en las áreas boscosas de las tierras bajas del Atlántico del estado de Río de Janeiro, por falta de educación ambiental, no estaban conscientes de la importancia de los ecosistemas naturales en el mantenimiento de su propia calidad de vida y del resto de las especies, a largo plazo. Los resultados obtenidos hasta ahora son halagadores y representan un ejemplo de esperanza en este tipo de iniciativas para conservar especies y ambientes en todo el mundo.

En el ámbito nacional han habido intentos de implementación de campañas de protección de algunas especies como el águila arpía, la rana dorada, el conejo pintado y la iguana verde, pero no han sido estructurados como programas de educación ambiental como tal.

La Ley 24 del 7 de julio de 1995 establece la legislación de Vida Silvestre contiene en el título segundo, capítulo tercero, realiza el mandato, exclusivamente a la educación, capacitación y extensión.

En términos generales, la educación ambiental para la conservación de la vida silvestre es importante porque favorece metas integrales (Jacobson, 1995), tales como:

1. El incremento de conocimiento del público y consecución de apoyo para el desarrollo de una apropiada política de conservación y manejo.

2. El fomento a la ética ambiental.

3. Los cambios de patrones de consumo de los recursos naturales.

4. El realce de las capacidades técnicas de los administradores de los recursos naturales.

5. Y la incorporación de los aspectos del manejo de recursos dentro del sector privado y los procesos políticos gubernamentales.

Para el logro satisfactorio de las metas arriba mencionadas, es necesario tomar en consideración según Hollingsworth y Nagagata (1995) un modelo de sistemas: la definición de los problemas ambientales más notables y las prioridades de conservación; la identificación y evaluación de la población involucrada, los recursos y los escenarios para construir una relación positiva de hechos para luego pasar a la etapa de selección, desarrollo y prueba de métodos, luego la implementación de las actividades y finalmente la evaluación y mejoramiento de los métodos educativos aplicados.

En resumen, el uso de educación ambiental para la conservación de la vida silvestre es un método práctico para aplicar esfuerzos coherentes de conservación de los recursos naturales como fin ultérrimo, porque implica un uso de manera directa e indirecta e integral de conceptos ambientales.

Marihuana, flora tropical y disciplina militar

Marihuana, flora tropical y disciplina militar

por: Ariel R. Rodríguez V.

Universidad de Panamá

El ejército norteamericano nunca pudo controlar en Panamá, la manía de sus soldados de fumar marihuana. Es muy probable que los soldados de hoy sigan siendo tan consumidores como lo fueron en Panamá hace muchos años sus abuelos. En la monografía de historia militar: Guarding the Gates The History of Fort Clayton… de los autores Susan I. Enscore y colaboradores del año 2000, se encuentra un interesante segmento que nos registra la historia de la influencia de la marihuana en la disciplina militar y en la política y la creación de leyes para controlar el uso de plantas psicotrópicas en Panamá. Ojalá, también, el tabaco hubiese sido incluido en esos tiempos en la lista de plantas non gratas para el consumo humano. Muchas muertes hubiesen sido evitadas o mejor dicho, muchas vidas hubiesen sido salvadas.

La historia nos dice que “al menos un planta nativa a la Zona del Canal», provocó cambios en la disciplina militar en Fuerte Clayton y en otros sitios durante los primeros años. La marihuana o mariguana o Cannabis sativa, crecía silvestre por todo Panamá y también era cultivada en muchas áreas. Algunos científicos indican que es una de las plantas cuyo cultivo, se considera, dio origen a la agricultura y que más se ha extendido por el mundo.

La marihuana posee diversas cualidades medicinales y terapéuticas, y además se ha utilizado en cultos religiosos en casi todo el mundo, desde los antiguos chinos y persas, hasta los griegos. Hoy en día, innumerables estudios realizados en el mundo, confirman las cualidades terapéuticas de esta, como analgésico, estimulante del apetito, anticonvulsionante, antiespasmódico, antidepresivo, tranquilizante, anestésico local, broncodilatador, entre otras, además de que no origina una dependencia física notable, si es utilizada correctamente y con fines meramente terapéuticos. Su principio químico activo, el D9-Tetrahidrocannabinol, es el principal componente psico-activo de esta planta, que posee una actividad analgésica y anti-inflamatoria.

Ante estas bondades terapéuticas no nos extraña que haya sido la planta favorita de los soldados norteamericanos en Panamá desde los albores de su llegada a Panamá, tal y como lo relata el ensayo arriba mencionado.

El cultivo y venta de la marihuana en Panamá no fue ilegal durante las primeras décadas del siglo veinte. Se estima que un buen porcentaje de soldados norteamericanos fumaban esta planta desde los primeros años de la presencia militar de Estados Unidos en el Istmo.

Opiniones médicas y populares durante las décadas de 1910 y 1920 indicaban que el consumo de la droga no presentaba problemas de adicción a largo plazo. Sin embargo, jefes del ejército norteamericano acantonados en Panamá, se quejaron ante sus superiores que la marihuana causaba problemas en la conducta de los soldados que la fumaban, ya que hacía que las tropas se volvieran incorregibles e inmanejables cuando estaban bajo su influencia.

Para 1923 el jefe del comando militar en Panamá, tomó medidas y dispuso que el consumo de esta droga por los soldados fuera castigado y considerado un delito militar. La República de Panamá actuando por la presión de los jefes militares estadounidenses pasó una ley ese mismo año, donde se castiga con prisión máxima de un año a quien vendiera o consumiera marihuana en el territorio nacional.

En 1926 el Gobernador de la Zona del Canal nombró un comité para investigar el uso de la marihuana y dar recomendaciones. Basados en una sesión donde estudiaron la conducta de cuatro policías que fumaron hojas de marihuana llegaron a la conclusión que la influencia de la marihuana cuando es fumada es incierta y que parecía haber sido grandemente exagerada. Concluyeron que no había evidencias médicas que indicaran que el consumo produjera demencia o locura y que no era una droga que producía narco-dependencia y recomendaron no prevenir la venta y consumo. Consecuentemente los delitos militares por posesión y uso fueron eliminados.

A pesar de los hallazgos del gobernador, los comandantes del ejército continuaron presionando por soluciones a los problemas con la disciplina militar ante el rápido incremento de tropas fumando marihuana. En 1928 el jefe del ejército ordenó una investigación adicional del problema. Un estudio de un año se llevó a cabo y consistió en remitir a todos los soldados sospechosos de fumar marihuana, pero al final se llegó a las mismas conclusiones del primer estudio de 1926 y por tanto se siguió permitiendo el uso de la planta como psicotrópico. Sin embargo, el 1 de diciembre de 1930, después de la llegada de un nuevo jefe militar del ejército, el consumo de marihuana fue completamente prohibido.

De acuerdo a un estimado para este período, un 20% de las tropas de Clayton consumían marihuana, seguido de Fort Davis con un 5%. Así una vez más en mayo de1931, el comandante del ejército le solicitó al Gobernador como máxima autoridad civil en la zona canalera que reinvestigara el uso de la marihuana por las tropas de los Estados Unidos. Así, un nuevo comité formado por personal médico militar y civil del Hospital Gorgas fue conformado para conducir la investigación.

Este esfuerzo incluyó estudios científicos dedicados usando marihuana cultivada y cosechada bajo condiciones controladas en los Jardines Experimentales del Canal de Panamá y observaciones de soldados voluntarios usando marihuana. Los hallazgos de esta investigación fueron mucho más amplios que los primeros hallazgos. Entre los hallazgos se determinó que el consumo de la marihuana entre los soldados era más común de lo que se pensaba y que la droga no era adictiva. El comité no encontró deterioro físico, ni mental en los soldados que la fumaban. Sin embargo, el comité concluyó (por conocimientos médicos y prácticos) que el uso habitual de cualquier estimulante o intoxicante causaba detrimento de la salud de una persona y recomendó mantener las restricciones de uso de esta droga en el personal militar. También el panel indicó que los jefes militares habían sobre enfatizado los efectos de la marihuana en la creación de soldados delincuentes.

No se tomaron acciones adicionales para el personal civil de la Zona del Canal. Muchos soldados siguieron fumando marihuana a pesar de las restricciones legales del ejército al respecto. Esta situación persistió sin mucho cambio hasta 1942 cuando el gobierno civil zoneíta prohibió la producción y venta de marihuana en lo que un día se denominó la Zona del Canal.

Esta historia patria es interesante, dado que no todo es como uno lo piensa o como creemos. Resulta que nuestros abuelos fueron chicos rebeldes y traviesos y muchos también fueron marihuaneros, como los jóvenes de ahora. En ese tiempo, se estudió el problema y se buscó una solución. Ahora en Panamá, la solución para los jóvenes con algún tipo de mala conducta social, sólo parece ser una: la cárcel, pero para los pobres, porque los niños ricos no serán tocados por la mano de la injusticia.

Así es Panamá, y sólo nos queda decir con desaire como dice un amigo catedrático universitario: Martín Torrijos Presidente, Vivian primera dama.

MARIAJUANA SMOKING IN PANAMA

Taken from: The Military Surgeon Volume 73 – July-December 1933

---

IN JUNE, 1931, at the request of the Commanding General, Panama Canal Department, a committee was designated to reinvestigate the effect of the smoking of mariajuana on military personnel, with a view to securing additional evidence that might possibly be used as a basis for the formulation of regulations forbidding the cultivation, possession, or sale of mariajuana in the Canal Zone. The Governor designated three members to serve on the committee (Health Department officials) ; the Army two members (officers of the Medical Corps) ; and the Commandant, 15th Naval District, one member (medical officer of the Navy).The committee concluded that the principal and most practicable method of securing reliable information would be to hospitalize a considerable number of soldiers who were known to be users of mariajuana, permit them to use it, then withdraw it and have the patients observed and studied throughout the period of hospitalization by a psychiatrist of high professional standing. The mariajuana used was grown at the Canal Zone Experiment Gardens, assuring uniformity of product. Thirty-four soldiers were observed.

It was deemed advisable as a matter of interest and for purposes of record to incorporate in the report a resume of the general information available relative to the cultivation, preparation, uses, and effects on human beings of mariajuana (Cannabis sativa L.) in various parts of the world, including its use as a stimulant and intoxicant on the Isthmus.

Mariajuana, mariahuana, marihuana, marijuana, Indian hemp, .Cannabis sativa L., Cannabis indica, and Cannabis americana are synonymous, and in this report the term mariajuana will be understood to apply to all the above terms.

It appears that mariajuana is not a correct term in the Spanish language but that it is a provincialism common to Panama and derived from the word «maraguango» The latter mentioned term is a general one and is interpreted to mean smoking, drinking, or snuffing of any substance that produces the loss of clear mentality, hallucinations, delusions, or disturbed sleep. The plant mariajuana, grown locally, is synonymous with Cannabis sativa L. or Cannabis indica and Indian hemp. Hemp is cultivated all over the world, its culture probably originating in China from whence it spread. It is cultivated for three purposes; for the fibre, out of which rope, twine, cloth, and hats are made; for the seed, from which a rapidly drying oil is obtained that is used in the arts and as a commercial substitute for linseed oil; and for the narcotic principle contained in the resin of the dried flowering tops of the pistillate plant. The seed is also sold as a constituent of commercial bird seed. It is not known when the plant was introduced into Mexico and the southwestern part of the United States, but probably along with the early Spanish settlers. It was introduced into Chile in the sixteenth century. The early cultivation of hemp in the United States was of the small European variety but this has been replaced since 1857 by the larger Chinese hemp. Practically all the seed for the present day American hemp culture is grown in the Kentucky River valley. Hemp is found growing wild in the’ , slough’, district of the Illinois River valley, especially in Tazewell County, where the gathering of the flowering tops is a local industry. The harvest is sold to the pharmaceutical trade. There is no evidence that the smoking of hemp or other abuse respecting this plant is practiced or known to those engaged in this occupation. Formerly, the majority, if not all, of the imports of Cannabis sativa into the United States was from India where hemp was largely cultivated for its narcotic principle. The menace of habit formation which its culture made possible led to the imposition of such drastic restrictions to its cultivation that the supply of Cannabis indica required by the United States had to be sought elsewhere. To meet requirements for pharmaceutical use in the United States the cultivation of Cannabis sativa became an industry in the United States, principally in the valleys of the Kentucky and the Illinois rivers.

Mariajuana is designated as a «narcotic» in the laws of several states. It is one of several drugs included in the anti-narcotic laws of sixteen states.

In India the plant is grown to some extent .for the fibre but also, and in some parts exclusively, for its narcotic principle. There are three principal forms in which it is prepared but of these there are many modifications. The first is that known as charas; the second, ganga; and the third, bhang. Charas is the resinous exudate found in the bark, the leaves and on the pistillate or female flowers, and even on the fruits. Ganga is an agglomeration of the pistillate flowering , stems with the exuded resin. Bhang consists of the dried mature leaves and to some extent the fruit but not the twigs.

Charas, the resinous substance which exudes naturally from the bark, leaves and pistillate flowers, is smoked for its stimulating, intoxicant, and narcotic effects.

Ganga is prepared from the pistillate flowering heads which must not be allowed to form fruit if the best quality of ganga is desired. The resin is pressed out and the mass of agglomerated flowers and resin is pressed into the desired shapes. Ganga, also is used for smoking for its stimulating, intoxicant, and narcotic effects.

Bhang consists of the dried leaves and to some extent the dried fruits of the plant. The resin is not extracted from this product; it is used directly in the preparation of the products which furnish the effect. One of these products is «hashish,» an intoxicating beverage. Another is a sweetmeat known in India as «majun» or «majum.» Bhang is made chiefly from the wild plants which grow abundantly as an escape from cultivation. Bhang is reported to be much weaker than ganga or charas and is supposed to be less injurious. The cultivation of mariajuana as a source of the active principle is a highly specialized one in India, and the plants are given special attention.

The plants are sexually distinct. The male plants yield little or no resin and are not allowed to remain in the field after their male characters have become apparent. It is endeavored to rid the field of all male (staminate) plants, which, if allowed to remain, fecundate the flowers of the female (pistillate) plants, causing the formation of fruits, in which process the pistillate plants .themselves rapidly deteriorate as sources of the desired active principle.

Mariajuana as grown among the Chiva.-Chiva Trail farmers in the Canal Zone.–In this locality (Pacific side of the Canal) there is cultivation on a small scale. Apparently some farmers grow only a few plants to supply their own wants, while others evidently have more than can be used by themselves and their families. The surplus is sold to soldiers. The plant is used to make tea; four or five, or more dried leaves are placed in a cup and steeped in boiling water. There is among the colored people great faith in the efficacy of this drink as a mild stimulant which gives a feeling of well being, and also as a preventive of malaria. The smoking of dried leaves and flower heads in the form of cigarettes seems also to be not uncommon.

Little attention is paid by the natives to removing the staminate (male) plants before pollen inaction and their leaves are often mixed with the leaves and flower clusters of the pistillate (female) plants, although it is generally understood that the former are much less potent. For these reasons it will be seen that mariajuana purchased locally is probably of quite variable character and tests of its physiological and mental effects in any experiment may be expected to vary likewise. For this reason the committee felt that the product to be used in its experiments should be specially selected material furnished by the Director of the Canal Zone Experiment Gardens.

No charas or ganga has been found among the military personnel in the Canal Zone, nor has either been found among the civilian personnel.

Uses in medicine–and action. –Mariajuana {Cannabis indica or C. sativa) is described in the Epitome of U. S. Pharmacopoeia, and National Formulary as a «narcotic poison, producing a mild delirium. Used in sedative mixtures, but of doubtful value. Also employed to color corn remedies.»

In the 20th edition of the United States Dispensatory there is the following description:

Aside from the local irritant effect the action of cannabis seems to be limited almost exclusively to the higher nerve centers. In man this is first manifested by a peculiar delirium which is accompanied by exaltation of the imaginative function and later by a remarkable loss of the sense of time. The delirium is often accompanied with motor weakness and diminished reflexes and generally followed by drowsiness. Cannabis is used in medicine to relieve pain, to encourage sleep, and to soothe restlessness.

The drug is used very little in the practice of medicine. It is considered unstable and unreliable and as there are other drugs which can be used to relieve pain and produce sleep the prescribing of this drug for these purposes is falling into disuse.

Mariajuana in the United States.-Recent legislation enacted by the Seventieth Congress, approved January 19, 1929, authorizes the establishment of two United States Narcotic Farms for the confinement and treatment of persons addicted to the use of habit forming narcotic drugs. The act specifically defines the term «habit-forming narcotic drug» and includes in the section which defines these drugs Indian hemp and its various derivatives but it does not appear in the other Federal anti-narcotic laws. The drug is included in the anti-narcotic laws of sixteen states.

In a «Memorandum on ‘dagga’ smoking and its evils» , published by the Department of Public Health, Union of South Africa, 1924, there is found the following report by the Rand Probation Officer :

There is a considerable amount of dagga (mariahuana) smoking amongst European males of the poor white and delinquent type, but I have never met an instance of the habit amongst intelligent or educated Europeans. All the European smokers I have met have acquired the habit during adolescence, though most have dropped it again in early manhood. It is sometimes acquired in boyhood from association with natives while herding stock or in similar occupations in the country.

The type of youth from whom the dagga smoker is recruited is generally of a low standard of intelligence, and the deteriorating effects of the drug react upon this nidus to confirm the habit early and to drag the smoker to the lowest depths.

The memorandum further states that :

The attraction of the drug is greatest for those living dull and monotonous lives, as in barracks, compounds, prisons, reformatories, hostels, etc:, and also for the degenerate or mentally unstable; the latter are especially prone to become addicts once they have experienced the drug.

In certain quarters of the town and in certain schools, «gangs» of lads between the ages of 10 and 16 years daily smoke three or more cigarettes containing dagga. The evil effects of the drug quickly show themselves in these immature youths by their emotional instability while under the influence of the drug and the dull, lack-lustre look that stamps their faces when the effects have passed off.

As far as can be ascertained mariajuana was not used for smoking by the personnel engaged in the construction of the Panama Canal, and police records do not show any cases of mariajuana intoxication during that time. In fact, the first information reaching police headquarters that mariajuana was being used here was about 1916 when the Chief of Police was informed that soldiers of the Porto Rican Regiment were smoking a «weed» which caused unusual symptoms. On investigation the officers of the regiment stated that they knew nothing of this and expressed surprise when the subject was brought up. The next reference to mariajuana was on May 26, 1922, when the Provost Marshal, Quarry Heights, Canal Zone, inquired of the Chief of Board of Health .Laboratory, Ancon, concerning the nature of mariajuana. Several months later the Chief of Police also made an inquiry concerning this drug and desired to know whether it was a narcotic drug within the meaning of the Narcotic Drug Act. From the correspondence it is evident that smoking mariajuana had become prevalent among soldiers on duty in the Zone and that there were cases of delinquency attributed to its use.

The first step on record to curb the use of mariajuana by the military authorities was in Circular No.5, Headquarters Panama Canal Department, dated January 20, 1923, which prohibited the possession of mariajuana.

There is no further reference to mariajuana until March 31, 1925, when the Department Commander wrote to the Governor suggesting that a conference of legal, medical, and police officers of the Panama Canal and also of the military authorities be arranged to consider the matter of mariajuana traffic.

A committee was appointed by the Governor on April 1, 1925, to investigate the use of mariajuana, and to make recommendations as to steps that should be taken for prevention of its use, including, if considered necessary, recommendations for special legislation. This committee consisted of the Chief Health Officer of the Panama Canal, the District Attorney, the Chief of the Division of Civil Affairs, and the Chief of the Division of Police and Fire; also, the Department Judge Advocate, the Chief of the Board of Health Laboratory, the Superintendent of Corozal Hospital for the Insane, and a representative from the Medical Corps, U. S. Navy , acting in an advisory capacity.

After an investigation extending from April to December, 1925, the Committee reached the following conclusion:

There is no evidence that mariahuana as grown here is a «habit-forming» drug in the sense in which the term is applied to alcohol, opium, cocaine, etc., or that it has any appreciably deleterious influence on the individuals using it.

The Committee recommended «that no steps be taken by the Canal Zone authorities to prevent the sale or use of mariahuana, and that no special legislation be asked for.»

The committee, in making its investigation, held hearings which were attended by the Post Commanders of Fort Clayton and Fort Davis. These officers were invited to give their opinions on the subject and to cite instances where mariajuana was the direct cause of military delinquency among soldiers. Members of the committee also visited Fort Davis and the Corozal Hospital for the Insane where they observed soldiers smoking mariajuana, and in addition members of the committee observed four physicians and two members of the Canal Zone Police Department who smoked the drug in their presence. Persons who smoked the drug at the request of the committee rendered written reports on the effect. Numerous written and oral statements of opinion were submitted for consideration. Military records of delinquency among the military personnel were also available and the committee found that in only a very small percentage of individuals brought to trial before General Courts Martial, in which there was a record of violence or insubordination, was it possible to attribute the delinquency to mariajuana.

The circular which forbade the possession of mariajuana was rescinded on January 29, 1926. In December, 1928, the law forbidding the possession and use of mariajuana in the Republic of Panama was repealed.

The findings of the Board, however, were not concurred in by most Army officers who exercised command directly over troops. The opinion among them was that mariajuana was a habit-forming drug and tended to undermine the morale of a. military organization when it was used to any extent by the personnel. There is correspondence on me in the Panama Canal expressing such an opinion and also expressing surprise at the findings of the committee.

On June 23,1928, the Department Commander directed that a further study be made of mariajuana. This study was to continue for one year. The circular letter directing the study reads in part as follows:

Par. 4. In pursuance of this study all cases -of suspected mariahuana intoxication and all cases of suspected mariahuana addiction will be sent to the Surgeon for investigation. The Surgeon will keep -a record of all cases sent, whether or not the use of mariahuana is established. Accurate clinical records of positive cases will be kept. Violations of discipline incident to the use- of the drug will be noted and that coincident with the use of alcohol or narcotics. Surgeons will submit monthly reports of all data upon the subject to the Department Surgeon.

Par. 5. It should be understood that only concrete facts are desired. Opinions or hearsay evidence are not wanted. …

On June 17, 1929, the Department Surgeon reported to the Chief of Staff that «the inquiry into the use of mariajuana by soldiers of the Department had been in effect a full year. The reports of the twelve months indicate that the use of the drug is not widespread and that its effects upon military efficiency and upon discipline are not great. There appears to be no reason for reviving the penalties formerly exacted for the possession and the use of the drug.»

On January 3, 1930, the Department Commander called the attention of all Commanding Officers to the fact that the possession or use of mariajuana was not per se a military offense and that in any trials or other proceedings taken with a view of the separation of individuals from the military service, any proposed defense alleging that wrongful acts or incapacity was the result of the use of mariajuana was not a defense and was not to be so considered.

There is no further reference to the subject until December 1, 1930, when the present Department Commander caused an order to be issued to the effect that «the smoking of mariajuana impairs the efficiency of the soldier and is forbidden. Soldiers smoking mariahuana or using it in any way will be brought to trial for each and every offense.»

There was still considerable traffic in the drug, and Company officers particularly complained of the deleterious effects on the men of their commands who used it. About six months after the publication of the order mentioned in the preceding paragraph (May 22,1931), the Department Commander write the Governor suggesting that the matter be reinvestigated with a view to securing additional evidence which might possibly be used as a basis for the formulation of regulations forbidding the cultivation, possession, or sale of mariajuana on the Canal Zone.

It had been reported that the use of mariajuana was particularly prevalent among soldiers at Fort Clayton and that it was easily obtained in various places along the Chiva-Chiva trail. According to reports it was also being smoked extensively by soldiers at Fort Davis.

On June 30, 1931, the committee first mentioned was designated to investigate the use and effects of mariajuana.

INVESTIGATION BY THE COMMITTEE

The committee at its preliminary meeting decided that its principal objective would be to hospitalize mariajuana smokers at Gorgas Hospital and have them observed by a psychiatrist, a member of the Board. It was considered that this afforded the best and most practicable method of obtaining first hand reliable information concerning the effects of the plant as used in this region. Permission was therefore obtained from the Department Commander to obtain mariajuana smokers from the enlisted personnel for hospitalization and study at Gorgas Hospital.

The committee also considered it desirable to obtain as much information as was practicable as to the extent of mariajuana smoking in military commands and the amount of delinquency caused by its use.

The study of the effects of mariajuana on the individual soldier included a complete neuropsychiatric examination, a clinical-study of the individual after smoking mariajuana, and a clinical study of signs and symptoms following its withdrawal.

The statistical data relating to the extent of mariajuana smoking in military commands and the delinquency that might be considered attributable to its use were secured from military sources by the Army members of the committee.

The problem of the Committee was therefore: 1. Determination of the extent to which mariajuana was being used by military personnel. 2. The physiological effects that result from the smoking of mariajuana. 3. Was military delinquency caused by mariajuana ?

Findings

1. Determination of the extent to which mariajuana is being used by military personnel. — The following figures are estimates only and were obtained from Post Surgeons through Department Headquarters. They represent the percentage of the command that is presumed to be mariajuana habitues :

Per cent Per cent

Fort Amador 0.6
France Field, 2.0
Fort Clayton. 20.0
Fort Randolph. 3.0
Fort Davis 5.4
Fort Sherman 2.6
Post of Corozal 3.1
Quarry Heights 3.0

2. The physiological effects that result from the smoking of mariajuana.–During the period from December, 1931, to October, 1932, for ;In average of six days in each case, thirty-four soldiers, collected from four posts in the Panama Canal Department, were observed in Gorgas Hospital for the effects of smoking mariajuana. These men, all known to be or suspected of being mariajuana smokers, volunteered to enter the hospital, tell all they knew about the use of mariajuana among soldiers in Panama and submit to any tests desired.

A. General facts:

1. The length of service in Panama of these soldiers varied from two months to four and eight-twelfths years, the average being one year and six months.

2. The chronological age varied from nineteen to thirty-three years, the average being 23 years.

3. Mental status : None exhibited psychotic symptoms. Sixty-two per cent were constitutional psychopaths and 23 per cent were morons, a total of 85 per cent mentally abnormal.

4. The length of time mariajuana was used by them varied from two months to four years, average period being one year and two months.

5. The quantity of mariajuana smoked daily varied from one to twenty cigarettes, average being five cigarettes.

B. Common effects of mariajuana described by users:

1. Mild intoxication. (Smokers use different terms to describe their sensations, the most common being «brushed up,» «high,» «happy,» «peppy,» «rosy,» «dopy,» «satisfied.»)

2. Increased appetite.

3. Induction of sleep an hour or two after smoking.

4. Only five, or 15 per cent, stated they missed mariajuana when deprived of it.

5. Twenty-four, or 71 per cent, stated they preferred tobacco to mariajuana.

6. These soldiers stated that mariajuana was cheap and easy to procure in Panama and that they used it for «a pleasant pastime,» usually during hours off duty when they had nothing else to do to amuse themselves. They stated that practically all recruits tried mariajuana and those who like it usually continued its use. Their average estimate of the number of habitual mariajuana smokers in their respective organizations was approximately 10 per cent.

C. Common effects of mariajuana observed in users:

1. No deprivation symptoms were observed even in those who admitted smoking eight to ten cigarettes the day previous to admission to hospital.

2. With the exception of three, all after smoking showed symptoms of mild intoxication. They lost reserve, became animated, laughed without adequate cause, and talked foolishly. During this stage, which lasted for half an hour to an hour or so, neurological and mental tests were performed as well as previously. There was no tendency to combativeness or destructiveness.

3. All stated they were very hungry after smoking and the quantity of food consumed at their subsequent meal confirmed this statement.

4. Pulse rate was markedly increased from a few moments after smoking first cigarette to an hour or more. There was no appreciable variation in blood pressure before and after smoking. There were no other distinctive physiological changes observed, other than a tendency to sleep, in which some indulged for a short while an hour or two after smoking.

5. No ill effects from smoking mariajuana for several days in succession were observed even when the soldiers were given mariajuana ad libitum.

Resume of Observed Cases

1. The smoking of mariajuana is quite common among soldiers in Panama.

2. Morons and psychopaths are believed to constitute the large majority of habitual smokers.

3. Mariajuana as grown and used on the Isthmus of Panama is a mild stimulant and intoxicant. It is not a «habit forming» drug in the sense that the derivatives of opium and cocaine are such drugs, as there are no symptoms of deprivation following its withdrawal.

4. Physiological effects observed in addition to intoxication were a marked increase in pulse rate and in appetite and the induction of sleep.

5. No mental or physical deterioration effects of smoking mariajuana could be demonstrated, but with this statement should be considered the fact that the soldiers observed were all young men who had smoked mariajuana for an average of less than two years.

6. From a medical standpoint the habitual use of mariajuana, as of other stimulants and intoxicants, should be considered detrimental to health.

7. Nothing was learned during the investigation to change our impression that the use of mariajuana by civilians on the Canal Zone is so slight as to be negligible.

8. The evidence obtained suggests that organization commanders in estimating the efficiency and soldierly qualities of delinquents in their commands have unduly emphasized the effects of mariajuana, disregarding the fact that a large proportion of the delinquents are morons or psychopaths, which conditions of themselves would serve to account for delinquency.

The committee had access to the records of the office of the Judge .Advocate of the Panama Canal Department (military headquarters). It was found that during the two year period ending June 30, 1932, of the total military personnel brought to trial before courts martial in only a very small proportion (1.17 per cent) was the soldier charged with having mariajuana in his possession, smoking mariajuana, or on account of other infractions of military discipline combined with the possession or smoking of the plant.

Delinquencies due to mariajuana smoking which result in trial by military court are negligible in number when compared with delinquencies resulting from the use of alcoholic drinks which also may be classed as stimulants and intoxicants.

Of the 51 members of the military personnel (1.17 per cent) in which the use or possession of mariajuana constituted one of the charges, in only 4 instances (0.09 per cent) was a charge of violence or insubordination connected therewith. The specifications in these four cases were as follows :

lst case: Possession of mariajuana ; drunk and disorderly in Colon and without proper pass; striking a military policeman. 2nd case: Possession of mariajuana ; disrespect to a noncommissioned officer. 3rd case: Possession of marlajuana; disobedience of orders. 4th case: Possession of mariajuana ; breaking arrest.

The .Assistant Adjutant General, Panama Canal Department, in a memorandum to the recorder of the committee stated that «During the last two years ninety-four (94) enlisted men were discharged on account of habits and traits of character which made their retention in the service undesirable; and of the cases examined only three (3) were attributable to the use of mariajuana.»

RECOMMENDATIONS

1.The present military regulations prohibiting the introduction, sale, possession, or use of mariajuana on military reservations should continue in force, as they are believed to restrict the use of mariajuana among soldiers.

2. With the evidence obtained and considered by the committee no recommendations for further legislative action to prevent the sale or use of mariajuana in the Canal Zone, Panama, are deemed advisable under existing conditions.
