RESUMO

Introducción : Para estudiar el efecto de cualquier producto natural, aunque sea de uso habitual de la medicina tradicional, es necesario establecer previamente los márgenes de seguridad para su utilización en humanos. En el caso de Erythroxylum coca, para trazar sus perspectivas de uso como fitofármaco o de producto industrial, es necesario conocer si tiene algún grado de toxicidad o si es completamente inocuo, no obstante, su larga tradición de consumo. Objetivo : Explorar el efecto de un extracto hidro-alcohólico de E. coca sobre granulocitos y mononucleares de voluntarios donadores humanos, en condiciones de cultivo celular. Se examinó, por un lado, el efecto sobre la viabilidad celular y la actividad del sistema mitocondrial/citoplasmático de óxido-reductasas y, por otra parte, se exploró su efecto sobre la funcionalidad celular a través de la determinación de la capacidad fagocítica, la quimiotaxis, la endocitosis y la actividad microbicida, en el ámbito de la inmunidad innata, y la capacidad de liberación o estimulación de citoquinas en el ámbito de la respuesta inflamatoria. Materiales y Métodos : Se evaluó la viabilidad por Azul Tripan, la actividad de oxido reductasas por reducción de MTT, la capacidad endocitica de levaduras, quimiotaxis en gel de agarosa hacia el péptido Fmlp y actividad microbicida sobre S.aureus. Las liberaciones de citoquinas se evaluaron por ELISA. Resultados : Se encontró que a las dosis equivalentes a la del consumo habitual humano, los leucocitos conservan su viabilidad (0,13µg/ml), la que se mantiene hasta dosis relativamente altas (130µg/ml). En esta franja de seguridad se encontró que E. coca no altera la capacidad de las enzimas mitocondriales y citoplasmáticas de óxido- reducción, al contrario, en dosis bajas es capaz de estimular dicha actividad. La actividad quimiotactica no es afectada por el extracto hidroalcoholico de coca por el contrario a dosis intermedias esta actividad se eleva de manera ostensible. La capacidad endocitica no se ve afectada y por el contrario se pudo observar un estímulo de la misma; en la actividad microbicida no existe cambios significativos. Conclusiones : Se concluye que, este producto a las dosis equivalentes a las recomendadas por la medicina tradicional no tiene efectos deletéreos sobre la viabilidad y funcionalidad de los leucocitos humanos. En lo que respecta a la actividad del extracto sobre la producción de citoquinas, se encontró que E. coca tiene efecto de estimulación en la liberación de TNF e inhibición de IL-10 modulando así mayor actividad proinflamatoria.


Introduction : In order to study the effect of any natural product, even if it is commonly used in traditional medicine, it is necessary to previously establish the safety margins for its use in humans. In the case of Erythroxylum coca, in order to trace its prospects of use as a phytopharmaceutical or industrial product, it is necessary to know if it has any degree of toxicity or if it is completely innocuous, despite its long tradition of consumption. Objective : To explore the effect of a hydro-alcoholic extract of E. coca on granulocytes and mononuclear cells of human donor volunteers, under cell culture conditions. We examined, on the one hand, the effect on cell viability and the activity of the mitochondrial/cytoplasmic oxidoreductase system and, on the other hand, it was explored its effect on cellular functionality through the determination of phagocytic capacity, chemotaxis, endocytosis and microbicidal activity, in the field of innate immunity, and the capacity of release or stimulation of cytokines in the field of inflammatory response. Materials and Methods : Viability by Trypan Blue, oxidoreductase activity by MTT reduction, endocytic capacity of yeast, chemotaxis in agarose gel towards Fmlp peptide and microbicidal activity on S.aureus were evaluated. Cytokine release was evaluated by ELISA. Results : It was found that at doses equivalent to the usual human consumption, leukocytes retain their viability (0.13µg/ml), which is maintained up to relatively high doses (130µg/ml). In this safety range it was found that E. coca does not alter the capacity of mitochondrial and cytoplasmic oxidation-reduction enzymes, on the contrary, at low doses it is able to stimulate such activity. The chemotactic activity is not affected by the hydroalcoholic extract of coca, on the contrary, at intermediate doses this activity is ostensibly elevated. The endocytic capacity is not affected and, on the contrary, a stimulus of the same was observed; in the microbicidal activity there are no significant changes. Conclusions : It is concluded that this product, at doses equivalent to those recommended by traditional medicine, has no deleterious effects on the viability and functionality of human leukocytes. Regarding the activity of the extract on the production of cytokines, it was found that E. coca has a stimulating effect on the release of TNF and inhibition of IL-10, thus modulating greater proinflammatory activity.

RESUMO

In Putumayo, a jungle borderland in southern Colombia, thousands of farmers derive their livelihood from the cultivation and processing of coca leaf, exposing themselves to fertilizers, pesticides, and other toxic chemicals on a daily basis. In this article, we show how the coca growers' relationship with chemicals and the health risks to which they are exposed, are politically and institutionally structured. We discuss the specific impact of anti-narcotics policy in a broader context of deep inequalities and document the emergent and adaptive day-to-day attempts of the farmers to navigate the structural risk environment.

RESUMO

As the world's second largest coca producer, Peru has a flourishing market for coca for non-narcotic uses. With more than 20,000 hectares and approximately 35,000 officially registered farmers in the Peruvian legal scheme for coca cultivation and commercialization, this market is formally under the monopoly of the National Enterprise of Coca (ENACO). Nonetheless, ENACO only captures 2% of all coca produced nationally and has experienced a sustained reduction of farmers' participation and coca purchases within the legal trade. At different times, these problems have opened the way to demands from left-wing political parties, subnational governments, coca growers' organizations and even Peru's central drug control institutions to reform the legal coca market in Peru. However, none of these attempts have succeeded. Based on a policy analysis of the legal coca trade and analysis of official data, together with a case study of Peru's main legal coca valley (La Convención) this article seeks to understand the current crisis of the legal coca trade as well as the repeated failures of reform. Peru's political centralism and the historical marginalization of Andean culture help to explain the successful blocking of reform attempts to the legal coca trade.

RESUMO

Chewing coca leaves is a habit still practiced in Bolivia, Peru and Argentina. There is scarce evidence in the relationship between this habit and development of oral squamous cell carcinoma (OSCC), some authors have found oral epithelial changes in coca chewers. This study aimed to present a case series of patients with a coca chewing habit that developed OSCC, in the absence of risk factors for oral cancer. Patients were evaluated in Hospital Señor del Milagro, Salta, Argentina. None of them had a relevant morbid history and presented intraoral tumors, with an ulcerated surface on the gingivobuccal complex. Coca chewing habit was recorded in all cases. Present cases could start discussions and new lines of researches focusing on the habit of coca leaves chewing as a risk factor for OSCC. It would be very useful to know the underlying mechanisms between this habit and a possible role in oral carcinogenesis.

RESUMO

BACKGROUND: Acute mountain sickness (AMS) may occur after rapid ascents to altitudes >2500 m. Cusco (3350 m) in Peru is a popular destination for altitude inexperienced travellers. This study aimed at evaluating the incidence and risk factors for AMS among a cohort of foreign Spanish language students in Cusco. METHODS: We performed a cohort study among young healthy foreign Spanish language students arriving to Cusco between 2012 and 2016. Consenting students answered an enrollment questionnaire on demographics, travel history and intended AMS preventive behaviour within 48 h of arrival. At 4-5 days after enrollment participants answered a second questionnaire about actual preventive behaviour before symptoms and the development of symptoms compatible with AMS during their first 48 h in Cusco. We used the 2018 Lake Louise Scoring System for AMS diagnosis. Participants with headache and a score ≥ 3 were considered to have AMS. RESULTS: We enrolled 142 language students, the median age was 21 years (interquartile range 20-25) and 57% were female. Participants decreased physical activity (38%), increased fluid intake (34%), drank coca leaf tea (34%), took acetazolamide (16%) and acclimatized at a lower altitude (6%) to prevent AMS. Thirty-nine percent had AMS. In the multivariate analysis, obesity [odds ratio (OR) 14.45 (2.33-89.6)] and female sex [OR 4.32 (1.81-10.28)] were associated with increased risk of AMS. Taking acetazolamide [OR 0.13 (0.03-0.56)] was associated with decreased AMS risk. Consumption of coca leaf tea was not associated with decreased risk of AMS. CONCLUSIONS: In our cohort, AMS affected two out of five travellers. Obesity and female sex were associated with increased risk. Drinking coca leaf tea for prevention did not decrease the risk of AMS. Acetazolamide prophylaxis was associated with decreased risk of AMS.

RESUMO

Drug Enforcement Administration's (DEA) Cocaine Signature Program previously identified 19 coca-growing regions within South America and developed methodology to geo-source cocaine using a combination of trace cocaine alkaloids, stable isotopes, and multivariate statistics. Twenty-nine coca leaf samples collected in 2016 and 2019 from a previously unanalyzed coca-growing region located in Puno, Peru, were analyzed with this methodology. Trace cocaine alkaloids and stable isotopes were compared with other Peruvian regions. Minor differences were observed in the extracted cocaine alkaloid profiles when compared with samples collected from the Ucayali-Huallaga Valley and Cusco-Apurimac regions while the stable isotopes of δ2 H (-177.1‰) and δ18 O (23.8‰) were enriched. Puno's alkaloid and stable isotope results are presented in this publication to assist forensic laboratories and enhance their cocaine geo-sourcing capabilities.

RESUMO

This paper compares coca with mainstream agrarian economies in Colombia. It shows that the country's legal and illicit sectors share several fundamental characteristics and processes. Due to its very illegality, coca is endowed with positive characteristics that are not easily found elsewhere: it is a productive - even in the absence of basic public goods -, familial, labor intensive, smallholder agriculture, relatively resistant to monoculture. Furthermore, different processes of social change have mitigated some of the typical problems of agrarian frontiers linked to global markets. In turn, its illegal status also imposes extreme costs over peasants and other social sectors. On the one hand, due to coca producers can escape from the "reproductive squeeze" and extreme pattern of land concentration that affect other peasants; on the other, coca becomes an unending source of risk and distress. This contradiction puts peasants in front of very tough tradeoffs, which in turn demand a careful reconsideration of what "alternative" development can mean in the Colombian context.

RESUMO

Many discussions of mafia and criminal entrepreneurs typically focus on violence and illegality, and less on their possible roles in rural transformation, even when they are located in borderland economies linking the subsistence cultivators of illicit crops to regional and global markets. This paper assesses the life stories of drug lords, the Castaño brothers of Colombia and Roberto Suárez Gomez of Bolivia, to draw inferences into how such rural elites in the illicit drugs trade are not only specialists in crime but are also actors who regulate and manipulate, often coercively, access to land and resources, mobilise labour and shape its divisions, and promote certain forms of capital accumulation. This paper contends that a better understanding of the roles of these rural elites as pioneers for capital, intermediaries in commodity chains, and arbitrageurs between state and borderlands may provide ways of unpacking key challenges to peacebuilding and economic transformation in borderlands where illicit economies thrive.

RESUMO

AIMS: This study aimed to determine the possible clinical and histological periodontal effects of long-term coca leaf chewing habit in habitants of the highland region of Peru. MATERIALS AND METHODS: A total of 100 residents, were recruited for the study. Fifty individuals were habitual coca leaf chewers and 50 were non-users. Eligibility criteria were: 60-80 years old, ≥20 teeth present (excluding third molars), systemically healthy (controlled systemic disease), not using medication affecting the gingiva. Chronic tobacco smokers were excluded. All participants completed questionnaires, received clinical periodontal examination, and had gingival biopsies harvested for histopathological assessment. RESULTS: Most coca leaf chewers reported several oral changes resulting from the habit, such as bitterness, numbness and mouth dryness, while none of the non-chewers reported experiencing such changes. Within the clinical periodontal parameters, it was found that there was a significant difference in terms of clinical attachment level loss, with a p value of 0.014 in those who chewed coca leaves, who appeared to have less clinical attachment loss. CONCLUSIONS: Chewing coca leaf produce bitterness, numbness and mouth dryness, and clinical attachment loss. Histologically higher number of inflammatory cells in the stratum spinosum, with more acanthosis, clear cell, and higher number of blood vessels.

RESUMO

Drawing on an ecological approach, we trace how the political-economy of drug wars are locally materialised in relation to health. We take the case of coca cultivation and eradication as our example. To make our analysis, we trace the different ways that the chemical glyphosate is materialised in a war with the coca plant in Colombia. Glyphosate has been used for decades in aerial fumigation campaigns to eradicate illicit coca cultivation. Our analysis traces the more-than-human effects of glyphosate in relation to health. This leads us to outline a more-than-human approach to harm reduction; a harm reduction which positions health as a matter of ecology, paying attention not only to the nonhuman actors affecting human health but also to the health of environments which are themselves always in-the-making. We envisage harm reduction as a collaboration in which humans 'become-with' their environments.

RESUMO

OBJECTIVE: The aim of this study was to compare in vitro the antibacterial activity of an ethanol extract of Erythroxylum coca Lam (EEE) and Schinus molle L. (EES) at 50% and 75% versus Streptococcus mutans ATCC 25175. MATERIALS AND METHODS: This was a prospective, comparative, longitudinal experimental study. The ethanol extract of coca and molle leaves was obtained by the vacuum filtration method at concentrations of 50% and 75% and was compared with a positive control (0.12% chlorhexidine). Streptococcus mutans strains were isolated in a culture medium (Mitis Salivarius Agar) ideal for the growth of bacterial colonies. The antibacterial activity of the ethanol extract was carried out following the Kirby-Bauer disk-diffusion method in Mueller-Hinton agar to measure bacterial sensitivity. A value of P < 0.05 was considered statistically significant. RESULTS: Evaluation of the antibacterial effect of EEE and EES at 24 and 48 h showed that a concentration of 75% for both groups had the highest antimicrobial activity against S. mutans (11.2 ± 0.7 mm; 11.6 ± 0.5 mm and 11.3 ± 0.7 mm; 11.8 ± 0.5 mm, respectively). So, the results have shown that the concentration of EEE and EES of 75% has a greater efficacy than the concentration of 50%, but both concentrations are not as effective as chlorhexidine. CONCLUSION: EEE and EES at concentrations of 50% and 75% present antibacterial activity against S. mutans ATCC 25175.

RESUMO

Paciente masculino de 21 años de edad, procedente y residente de la provincia de Chulumani, acudió al servicio de Emergencias del Hospital de Chulumani tras la ingesta accidental de insecticida que tenía como principal componente "cipermetrina" que es un piretroide sintético, presento paro respiratorio rápidamente, asociado a deterioro de estado de conciencia por lo que fue intubado y requirió asistencia ventilatoria mecánica, y posteriormente transferido a la Unidad de Terapia Intensiva del Hospital Juan XXIII del departamento de La Paz, tras su internación se pudo evidenciar las características clínicas propias de intoxicación por piretroides, que no es una entidad común en nuestro medio, entre los síntomas presentes en el paciente encontramos: deterioro de estado de conciencia, pupilas puntiformes, fasciculaciones fasciales, temblores e hiperexcitabilidad en extremidades superiores e inferiores frente a estímulos externos, hipotermia, sialorrea, diaforesis profusa y persistente, bradicardia, diarrea y debilidad proximal de extremidades con perdida de la fuerza muscular, lo que llevo a una estadía prolongada en la UTI, destete prolongado y fracaso de extubación en una oportunidad. Se logró el retiro definitivo de ventilador mecánico después de 20 días de internación e intubación. Ante síntomas semejantes a la intoxicación por organofosforado recibió tratamiento en base a atropina y medidas de soporte vital propias de la Unidad de Terapia Intensiva, optimizando la rehabilitación integral y respiratoria del paciente.


A 21-years-old male patient, dweller from Chulumani province, went to the Hospital of Chulumani Emergency Service after accidental intake of cypermethrin which is a synthetic pyrethroid insecticide. Patient presented respiratory arrest associated to deterioration of his state of consciousness, intubation and mechanical ventilation was performed. Subsequently, patient was transferred to the intensive care unit of Hospital Juan XXIII in La Paz city. After hospital admission, clinical proper characteristics of a pyrethroid intoxication, which is not a common entity in our environment, were observed. Signs such as deterioration in the state of consciousness, pinpoint pupils, fascial fasciculation, tremors and hyperexcitability in upper and lower limbs to external stimuli, hypothermia, sialorrhea, profuse and persistent diaphoresis, bradycardia, diarrhea and proximal weakness of limbs with loss of muscle strength were evidenced. This leaded to patient's prolonged staying in ICU and weaning as well as extubation failure at an opportunity. Definitive removal of mechanical ventilator was achieved after 20 days of hospitalization and intubation. Given symptoms similar to organophosphate poisoning patient received a treatment based on atropine and life support measures of the Intensive Care Unit, optimizing in this way patient's respiratory and integral rehabilitation.

RESUMO

The genus Erythroxylum contains species used by indigenous people of South America long before the domestication of plants. Two species, E. coca and E. novogranatense, have been utilized for thousands of years specifically for their tropane alkaloid content. While abuse of the narcotic cocaine has impacted society on many levels, these species and their wild relatives contain untapped resources for the benefit of mankind in the form of foods, pharmaceuticals, phytotherapeutic products, and other high-value plant-derived metabolites. In this review, we describe the current state of knowledge of members within the genus and the recent advances in the realm of molecular biology and biochemistry.

RESUMO

Actualmente el fluido oral (FO) es aceptado como una matriz biológica alternativa para detectar drogas en toxicología clínica y forense. En países como Argentina donde el uso de hojas de coca (mascar hojas de coca o beber té de coca) es legal son necesarios procedimientos adecuados para logar una clara diferenciación entre los individuos que usan las hojas de coca de manera legal de aquéllos que usan cocaína en forma ilegal. Poca es la información que hay en la literatura sobre el perfil de los alcaloides de la hoja de coca en FO de personas que mascan hojas de coca o toman té de coca y hasta el presente trabajo no se hallaron datos sobre el perfil en FO de la higrina (HIG) y cuscohigrina (CUS). De este estudio preliminar participaron dos voluntarios. Los resultados mostraron que la CUS e HIG siguieron siendo positivas después que la cocaína (COC) y benzoilecgonina (BE) cayeron por debajo de los valores cut- off propuestos por las guías internacionales para FO en casos de screening (15 a 20 ng/ mL) y de confirmación (8 a 10 ng/mL) en el caso del mascador de coca. En el participante que tomó una taza de té de coca, en el último punto examinado (1 h) resultó ser positivo para la COC y BE y también para la CUS e HIG. El FO podría ser una muestra útil para confirmar el uso legal de la hoja de coca, aun cuando futuros estudios son necesarios para corroborar estos primeros datos.


Nowadays oral fluid (OF) is accepted as an alternative biological sample for detecting drugs in clinical and forensic toxicology. In countries like Argentina, where the use of coca leaves (coca leaves chewing and coca tea drinking) is legal, adequate procedures are required to allow a clear differentiation between people who use coca leaves (legal practice) and those who use cocaine (illicit practice). There is scarce literature regarding coca leaf alkaloids profile in OF from people who chew coca leaves and drink coca tea. Until now, coca leaf alkaloids profile of hygrine (HYG) and cuscohygrine (CUS) in OF were not described in the literature. The current preliminary study was performed with two healthy volunteers. In this research CUS and HYG have been found to be positive (detectable) even when cocaine (COC) and benzoylecgonine (BE) are dropped below the cut-off values proposed by international guidelines for screening (15 to 20 ng/mL), and confirmation (8 to 10 ng/mL) in OF. In addition, CUS and HYG were also found to be positive at the same time of the last detection of COC and BE after coca tea consumption. The OF would be a useful sample to confirm the legal use of coca leaf, even when more researches are therefore needed.

RESUMO

El objetivo del presente artículo es ofrecer una perspectiva histórica de investigaciones sobre cocaísmo y alimentación en el hombre andino durante la segunda mitad del siglo XX. El hábito del cocaísmo fue considerado un importante problema de salud del Perú en los 40s, cuando el debate académico planteaba asociación entre deficiente alimentación y cocaísmo, atribuidos a la cocaína. Años después, estudios epidemiológicos apoyaron este paradigma. Desde los 70s, publicaciones antropológicas cuestionaron esta asociación y defendieron el uso social de la coca. En los años 80 se demostraron efectos farmacológicos de la coca y cocaína en la reducción del consumo de alimentos en animales de experimentación, que apoyaron la antigua hipótesis de Gutiérrez-Noriega.


The objective of this paper is to offer a historical perspective about the scientific investigations respect to the chewing of coca leaves and food ingestion of the Andean population during the second half of the twentieth century. The habit of cocaism, attributed to cocaine, was discussed one of the most important problems of Public Health in Peru during the 40s, period when the academic debate of the association of deficient food and cocaism was discussed. Years later, epidemiological studies supported this paradigm; however, since the 70s, anthropological reports questioned that claim and defended the social use of coca chewing. During the 80s the pharmacological effects of coca and cocaine were demonstrated in reduction of food consumption in experimental animals, which supported the old Gutierrez-Noriega´s hypothesis.

RESUMO

RESUMEN Objetivo Analizar el comportamiento de la malaria en relación con la economía de la coca en la región del Guaviare, Colombia entre 1978 y 1989. Métodos Revisión documental retrospectiva, a través del análisis de archivos históricos, entrevistas y fuentes secundarias. Resultados Se identificaron dos periodos de crisis de la bonanza coquera o cocalera durante el tiempo de estudio, con fluctuaciones en el número de habitantes. Al analizar la relación entre las variaciones del precio de la cocaína y los casos de malaria, se encontró que hay un incremento de casos en épocas de crisis. Conclusiones El aumento de casos de malaria en la región posiblemente se deba a que las personas que estaban en las zonas rurales se desplazaron a las cabeceras urbanas, motivadas por la baja producción de la pasta de coca. Esto incrementó la concentración de población susceptible y, por tanto, el aumento de casos, o probablemente existió un aumento en el registro de la enfermedad.(AU)


ABSTRACT Objective To analyze the relationship between malaria and coca economy in the region of Guaviare, Colombia between 1978 and 1989. Materials and Methods Retrospective documentary analysis using historical archives, interviews and secondary sources. Results Two critical periods for the coca bonanza, with population fluctuations, were identified between 1978 and 1989. After analyzing the relationship between variations in the price of cocaine and positive cases of malaria, an increase in cases was identified during those crises. Conclusions The increase of malaria cases in the region is possibly associated to the migration of people from rural areas to urban centers, motivated by the low production of coca paste. This increased the concentration of susceptible population and, therefore, the number of cases; however, it is possible that the report of these cases experienced an upsurge.(AU)

RESUMO

The Bioarchaeology of Care approach developed by Tilley is usually applied to skeletalized human remains, given the usual constraints of preservation bias that are seen with archaeological assemblages. However, other tissues, such as hair are sometimes preserved and can provide a wealth of information that can supplement the skeletal data. Archaeological hair has been analysed for drug compounds for almost thirty years. This article integrates data from hair analyses for coca metabolites, stable light isotope analysis and aDNA to expand the potential of the Bioarchaeology of Care approach using the example of a spontaneously mummified adult female from northern Chile.

RESUMO

As part of national and international cooperation to fight the drug-trafficking system, the Colombian National Police (PNC) has created institutional operational synergy to combat organised armed groups. To this end, it uses police service dog and handler teams which are distributed across Colombia in 75 canine units and which are specialised in different policing tasks. The focus of canine teams is to counter actions that undermine peaceful co-existence and citizen security by checking for explosive substances around coca, marijuana and poppy fields. In 2016, these teams discovered 16% of the 12,500 kg of improvised explosive devices, anti-personnel mines and unexploded ordnance (conventional guns and grenades) that were seized by the PNC. In addition, dogs have detected 19% of all controlled substances (cocaine, marijuana, heroin, coca paste and synthetic drugs) seized at ports, airports, land terminals and highways, striking a blow at drug-trafficking structures at all stages, from the illicit cultivation of drugs, through to their production, distribution, sale and use, countering small-scale dealing and the factors associated with drug-related social disorder. It is the responsibility of the PNC Police Service Dog and Handler Training School (ESGAC) to provide a framework for academic endeavour and technological advances aimed at achieving defined strategic roles for dog and handler teams. This involves the genetic selection and breeding of candidate detection dogs, assessment, training, operant conditioning, odour-discrimination during searches, certification, dog/ handler relationship, the dogs' living environment, and animal health, production and welfare management. All of the above is designed to achieve real, effective and successful outcomes when policing with dogs, enshrined within the national government's Vision 2030 project for safe and peaceful communities.


Dans le cadre de la coopération nationale et internationale contre les réseaux de trafic de stupéfiants, la police nationale de Colombie a mis en place une synergie opérationnelle institutionnelle contre les groupes armés organisés. Pour ce faire, elle recourt à des binômes d'intervention (un maître-chien et un chien) répartis en 75 unités cynotechniques sur tout le territoire colombien, spécialisés dans différentes tâches opérationnelles. La contribution des équipes cynotechniques consiste à neutraliser les activités qui menacent la cohabitation et la sécurité des citoyens, en détectant la présence de substances explosives aux alentours des champs de culture de cocaïne, cannabis et pavot, celles-ci ayant représenté 16 % des engins explosifs improvisés, mines antipersonnel et munitions non explosées (fusils et grenades conventionnelles) saisis par la police colombienne en 2016 sur un total de 12 500 kg. De surcroît, les chiens ont détecté 19 % du total des saisies de substances illicites (cocaïne, cannabis, héroïne, dérivés de cocaïne et drogues de synthèse) dans les ports, aéroports, gares routières et routes. Ceci atteint les structures du narcotrafic depuis les cultures illicites jusqu'à la production, la distribution, la commercialisation et la consommation tout en neutralisant le microtrafic ainsi que d'autres facteurs liés à la décomposition sociale due aux drogues. L'École de maîtres-chiens et de dressage de chiens de la Police colombienne prend en charge les efforts de formation ainsi que la recherche technologique afin que les fonctions stratégiques attribuées aux binômes soient réalisées avec succès. Ceci requiert la prise en compte de plusieurs aspects : la sélection génétique, la reproduction, les chiens potentiellement candidats pour être formés à la détection de drogue, l'évaluation, la formation, la gestion comportementale opérationnelle, la capacité de discriminer entre les odeurs lors des recherches, la certification, la relation entre le maître-chien et son chien, l'habitat, la gestion sanitaire et zootechnique ainsi que la protection du bien-être animal. Ces différents aspects sont destinés à garantir l'efficience et l'efficacité des résultats concrets obtenus par les services de la police cynophile dans le cadre de la stratégie institutionnelle 2030 « Pour des communautés sûres et en paix ¼.


En el marco de la cooperación nacional e internacional contra el sistema del narcotráfico, la policía nacional de Colombia (PNC) establece una sinergia operacional institucional contra los grupos armados organizados (GAO). Para ello, emplea binomios (guía-perro), distribuidos en forma de 75 unidades caninas por todo el territorio colombiano, especializadas en diferentes tareas del servicio. La contribución de los equipos caninos consiste en contrarrestar las acciones que afectan a la convivencia y seguridad ciudadana, controlando sustancias explosivas alrededor de los cultivos de cocaína, marihuana y amapola, en los cuales se ha logrado hallar un 16% de artefactos explosivos improvisados, minas antipersona y munición sin explotar (fusiles y granadas convencionales) de un total de 12 500 kg incautados por la PNC (año 2016). Además, los perros han detectado un 19% del total de las incautaciones de sustancias controladas (cocaína, marihuana, heroína, bazuco y drogas sintéticas) en puertos, aeropuertos, terminales terrestres y carreteras, golpeando así las estructuras narcotraficantes desde los cultivos ilícitos, la producción, la distribución, la comercialización y el consumo, y contrarrestando el microtráfico y los factores asociados a la descomposición social de las drogas. Son responsabilidad de la Escuela de Guías y Adiestramiento Canino de la institución los esfuerzos académicos y avances tecnológicos que propenden a lograr roles estratégicos definidos para los binomios, para los cuales son necesarios la selección genética, la cría, los perros detectores aspirantes, la evaluación, la formación, el manejo comportamental operativo, la discriminación de olores durante la búsqueda, la certificación, la relación guía perro, su hábitat, y el manejo sanitario, zootécnico y relativo al bienestar animal. Todo lo anterior va destinado a lograr resultados efectivos, eficientes y eficaces en el servicio de policía con caninos en el marco de la visión institucional 2030 «Comunidades Seguras y en Paz¼.
