Study of cocaine seizures through spatial analysis

Cocaine trafficking and consumption continues to prosper despite the public policies that are in force in Brazil, despite its use for thousands of years, it is currently a public health problem. This study aimed to report the sociodemographic variables of individuals apprehended with cocaine and who were framed in Law n°. 11,343 of August 2006, in the municipality of Campina Grande, in 2017. It was a hybrid study, with a transversal, retrospective cut and ecological, with a quantitative approach. The neighborhood area variable was distributed in thematic maps and the spatial autocorrelation was measured by the Moran Global and Local indexes, which quantify the degree of autocorrelation. 210 cocaine seizures were recorded, of which 146 occurred in the municipality of Campina Grande, of these, only 94 presented all the data and were considered in this study. The months of September (n = 14) and October (n = 13) had the highest records of seizures. As for the pattern of use, crack in the yellowish stone form was predominant (n = 46), followed by cocaine hydrochloride in the form of white powder (n = 40). The profile of the individual apprehended with cocaine in the municipality was that of a young, single, unemployed and with low level of education. The predominant framework was drug trafficking (n = 75) according to Article no. 33 of Law no. 11,343 / 2006. The neighborhoods that registered the highest number of seizures were José Pinheiro (n = 15) and Pedregal (n = 8). The Moran General and Local indexis (p> 0.05), did not show spatial dependence between neighboring neighborhoods, that is, there is no autocorrelation for the analyzed variable.


Introduction
In Brazil, the problem of drugs is the subject of discussions in various spheres of public policy, attempts to remedy or control the disorder are recurrent. Until the 1920s, official laws regulating the issue of illicit drugs in the country were nonexistent. At the time of the great industrial explosion and modernization of the country in 2009, the use of drugs, which previously was restricted to some upper-class youths who frequented brothels, started to occupy other social spheres such as low-income people and homeless people, classes considered at the time as dangerous and risky to society ).
This spread began to disturb government officials and the Brazilian elite, which promptly, in 1921, implemented a law that forbade the use of opium, morphine, heroin and cocaine in the country, whose accused was liable to severe punishment.
The restriction on the use of drugs remains until today, receiving additions and changes over the years according to social need, and thus the reasoning of the public policy framework around the regularization of drug use and narcotics in Brazil begins (Carvalho, 2011).
In the year 1938, based on the aspects discussed in the International Opium Convention signed in The Hague on January 23, 1912, the need to regulate through the Decree-Law nº. 891, entitled as Narcotics Inspection Law inspection and taking appropriate measures for the use of narcotics, mainly the condemnation of the use of opium and cocaine, in addition to other drugs such as marijuana and heroin. The decree classified addiction to drugs as a "compulsory notification disease", which should be treated in specialized centers and not at home, thus creating a range of psychiatric hospitals, as provided in article 29 § 1st (Rio de Janeiro, 1938).
In 1980, the National Narcotics Prevention, Inspection and Repression System was established. The creation of the Federal Narcotics Council (COFEN) was standardized, backed by Decree nº. 85,110 (Federal District, 1980). The creation of COFEN represented the genesis of all public actions related to narcotics still in force.
Then there was the Fund for Prevention, Recovery and Combating Drugs of Abuse (FUNCAB), which disposes of acquired goods with illicit drug trafficking products or related activities through Law nº. 7,560 of December 1986(Brazil, 1986. From FUNCAB came FUNAD -National Anti-Drug Fund. In order to technically supervise all actions related to combating drug trafficking in 1993, the Ministry of Justice created the Federal Narcotics Secretariat. In 1998 it was renamed the National Anti-Drug Secretariat (SENAD) together with the former CONFEN, which became CONAD -National Anti-Drug Council. Both bodies were separated from the Ministry of Justice and became part of the Military House of the Public Presidency (Brazil, 2019).
Through Decree nº. 4,345 of August 26, 2002, everything that had already been widely discussed was incorporated into the National Anti-Drug Policy (PNAD) (Distrito Federal, 2002). In the same year, Law nº. 10,409 of January 11, repealed Law nº. 6,368 of October 21, 1976, maintaining several points in relation to the reduction in the supply of narcotics (Brasil, 2002).
In an attempt to unite the two Laws nº. 6,368 / 1976 andthat of nº. 10,409 / 2002, previously enacted, Law nº. 11,343 of August 23, 2006, reaffirming the necessary measures for prevention, care and social reintegration of individuals with some drug-related disorder through the institution of the National System of Public Policies on Drugs (SISNAD), which was also responsible for the differentiation between the figure of the dealer and the user / addict, who started to receive differentiated treatments, occupying different articles (Brasil, 2006). Also, in 2006, Decree nº. 5.912 determined and regulated what is the responsibility of the Executive Bodies in relation to the topic (Distrito Federal, 2006;Diel & Gimenez, 2014).
On July 23, 2008, Law nº. 11,754 was introduced, which adapts the term used to refer to public policies related to the use of narcotics. Thus, the National Anti-Drug Council was renamed the National Drug Policy Council (CONAD) and likewise the National Anti-Drug Secretariat was also renamed the National Drug Policy Secretariat (SENAD). In 2011, SENAD is once again part of the Ministry of Justice organization chart (Brazil, 2008 This set of laws, ordinances and decrees made it possible to generate epidemiological, sociodemographic data on the trafficking and seizure of illicit drugs. The surveillance system consists of a continuous process of collecting, analyzing, interpreting and disseminating information in order to recommend and adopt measures to prevent and control the use and trafficking of illicit drugs nationally and internationally.

Epidemiology
According to the United Nations Office on Drugs and Crime (UNODOC), 5.6% of the world population aged between 15 and 64 years used drugs at least once in 2016. The ranking of drug use this same year was led by cannabis sativa, popularly known as marijuana, having been consumed by 192 million people, followed by opioids (34 million people), amphetamines and stimulating drugs (34 million people), "ecstasy" (21 million people), opiates (19 million people) and finally cocaine, used by 18 million people worldwide (United Nations Office on Drugs and Crimes, 2018).
Despite not being used as much as other drugs, cocaine has a high additive power, leading to serious complications and even death. In the United States the number of deaths related to cocaine use has doubled in three years, with a record of 10,000 deaths in 2016, while in 2013 there were only 5,000. Despite having a lower number, when compared to the American Research, Society andDevelopment, v. 10, n. 3, e48610313571, 2021 (CC BY 4.0) | ISSN 2525-3409 | DOI: http://dx.doi.org/10.33448/rsd-v10i3.13571 continent, Asia and Africa registered the highest growth rate of cocaine seizures in 2016, reflecting the rapid spread of trafficking to less used markets (United Nations Office on Drugs and Crimes, 2018).
Colombia remains the world's largest producer and supplier of cocaine. In 2016, global cocaine manufacturing reached its highest level in history, with an estimated production. Africa and Asia are emerging as centers of drug trafficking and consumption (United Nations Office on Drugs and Crimes, 2018).
According to the III National Survey on Drug Use by the Brazilian Population, published by the Oswaldo Cruz Foundation, in 2015 the number of consumers, aged between 12 and 65 years, who used illicit drugs at least once in their lives was approximately 9.93%, in which cocaine corresponds to 3.06% of use, and crack / similar to 0.91%. Male gender is prevalent in both drugs, as confirmed by the literature (Fiocruz, 2017;Horta, Balbinot, Teixeira, Pinto, Oliveira & Poletto, 2016). The rapid process of industrialization in concomitance with the population agglomeration coming from the countryside cities culminated in the formation of peripheral centers, with high crime rates. Therefore, global problems such as drug trafficking and consumption, possession of weapons, robberies and thefts, among other crimes that plague the country, have become an increasingly present reality, requiring systematic actions and control through the federal police, civil and military, through public policies (Queiroz, 2008;Silva, 2014).

Traffic x Size
For a substance to be considered for banned use in Brazil, it must be present in Annex I of Ordinance 344 of May 12, 1998. This ordinance is constantly updated by ANVISA. For the individual to be framed for possession or trafficking in narcotic substances by Law 11.343 / 2006, the drug must be included in the list provided by this Ordinance (Brasil, 1998). Art. 28. Anyone who purchases, keeps, has in deposit, transport or brings with him, for personal consumption, drugs without authorization or in disagreement with legal or regulatory determination will be subject to the following penalties: I -warning about the effects of drugs; II -provision of services to the community; III -educational measure of attendance to an educational program or course (Brasil, 2016).
Article 33 of the same law addresses the accused framed for drug trafficking: Art. 33. Import, export, send, prepare, produce, manufacture, acquire, sell, exhibit for sale, offer, keep in deposit, transport, bring with you, store, prescribe, minister, deliver for consumption or supply drugs, even if free of charge, without authorization or in breach of legal or regulatory determination: Penalty -imprisonment from 5 (five) to 15 (fifteen) years and payment of 500 (five hundred) to 1,500 (one thousand and five hundred) days-fine (Brazil, 2016).
In section I of chapter III with regard to the investigation, Article 50 of Law nº 11.343 / 2006 deals with the materiality of the crime: Art. 50. In the event of a flagrante delicto arrest, the judicial police authority will immediately communicate to the competent judge, sending him a copy of the drawn up record, which will be given to the Public Prosecutor's Office, within 24 (twenty-four) hours. § 1 For the purpose of drawing up the arrest record in the act and establishing the materiality of the crime, the report on the nature and quantity of the drug, signed by an official expert or, failing this, by a suitable person, is sufficient. § 2 The expert who subscribes to the report referred to in § 1 of this article will not be prevented from participating in the preparation of the final report (Brazil, 2016).
Worldwide, the CRIMJUST project contributes to effectively combating organized crime in general and drug trafficking in particular along the cocaine routes in Latin America, the Caribbean and West Africa, in accordance with international legal instruments and human rights. Approximately 1,579 people participated in 61 CRIMJUST training courses in 2017, which will help strengthen law enforcement capabilities and the judiciary to detect, collect evidence, investigate, and prosecute drug trafficking cases across national borders and improve cooperation between criminal justice institutions (United Nations Office on Drugs and Crimes, 2018).

Cocaine
Cocaine is a drug that has been used for thousands of years, from pre-Incan and pre-Columbian peoples, until the 19th century, where its medicinal properties became popular and scientifically known through the "Form" or "Medical Guide and the Dictionary of Popular Medicine", written by the polish Pedro Luiz Napoleão Chernoviz (1812-1881) (Torcato, 2016). It is an alkaloid extracted from two species of the genus Erytroxylum, Erytroxylum novogranatense and Erytroxylum coca cultivated in different regions of the world (Freye, 2009).
Reports of cocaine use date back more than 1,200 years, when the South American natives of the Andes already used E. Coca leaves, for their stimulating properties (Pozner, Levine & Zane, 2005). It was isolated and characterized by Albert Niemann in 1859 (Chasin, Silva & Carvalho, 2014).
Used since pre-Incan peoples as drug therapy and in religious celebrations, cocaine in the 20th century became popular in the form of crystalline powder, being cocaine hydrochloride or cocaine sulfate, water-soluble salts, for nasal or intravenous use. Due to its high boiling point, around 187 ° C, it does not volatilize and decomposes as the temperature increases (Rodrigues, 2010). Research, Society and Development, v. 10, n. 3, e48610313571, 2021 (CC BY 4.0) | ISSN 2525-3409 | DOI: http://dx.doi.org/10.33448/rsd-v10i3.13571

The pharmaceutical industry's attention to this alkaloid was soon aroused, having been formulated several types of medicines, from cough syrups to anesthetics used in surgical procedures. With the frequent use of cocaine-based drugs by the population, the toxic effects and its addictive character became evident, culminating in its withdrawal as a pharmaceutical input, starting to be treated as a drug of abuse, lasting until today (Fernando & Fuzinatto, 2012;Moreira, 2015).
The problem involving not only cocaine, but all illicit drugs, results of constant specialization and improvement of world trafficking, that is, it is useless to fight against a type of isolated drug, given that this issue must be treated as a whole since there is an interconnection between suppliers and users ).
Mentioned as one of the most complex public health problems, cocaine can be consumed in the form of cocaine hydrochloride, inhaled and injected, or smoked in the form of free base in "pipes" popularly known as crack, which presents the same symptoms, but in a more intense and less lasting way, having an even greater capacity of addition for the user (Duailibi, Ribeiro & Laranjeira, 2008).
The table below (Table 1) demonstrates the different routes of use of cocaine, the time for the effect to begin, the purity in percentage of cocaine, the duration of the effect, the bioavailability of the substance and its metabolites, and the half life of this in the body. We can observe that the respiratory route provides the hallucinogenic effect more quickly, however, the duration is significantly shorter, generating in the user the need to consume even more drugs, as is the case of crack. Cocaine goes through an extensive production process, from plantations to Erytroxylum even the traffic on the streets.
The dried leaves go through an extractive process of maceration with organic solvent or acid solution, from which the base paste with high cocaine content is obtained, used as raw material to manufacture the forms of the commercialized drug.
Approximately 100 kilograms of coca leaves are needed to make 800 grams of cocaine hydrochloride. Cocaine hydrochloride is obtained from the base paste (Chasin, Silva & Carvalho, 2014).
Due to the physical-chemical impossibility (low volatility), traffickers and users started to carry out tests by means of chemical reactions aiming at the volatilization of the drug, and thus cocaine appeared in the form of free base, popularly known as freebasing, crack, merla and bazuco, among other denominations around the world (Oliveira & Nappo, 2008) The crack It is obtained by dissolving Cocaine Hydrochloride (COC.HCL) in water and adding alkalizing agents, such as sodium bicarbonate or sodium hydroxide, followed by heating and cooling the mixture. The name crack came up in the United States, refers to an onomatopoeic expression that resembles the sound of crackling due to the heating of the drug due to the presence of sodium chloride, an impurity that appeared in the process of converting cocaine to crack (Chasin, Silva & Carvalho, 2014).
Research, Society and Development, v. 10, n. 3, e48610313571, 2021 (CC BY 4.0) | ISSN 2525-3409 | DOI: http://dx.doi.org/10.33448/rsd-v10i3.13571 7 The route of consumption of the drug is a determining factor in the rate of absorption and, consequently, in the plasma peak and bioavailability. The two most used routes are the "sniffed" intranasal using cocaine hydrochloride and the "smoked" respiratory tract using the free base. We still have the oral and intravenous routes of less use (Boghdadi & Henning, 1997;Mosquera & Menéndez, 2005).
Through the pulmonary alveoli, the smoked form has the highest absorption speed, with a faster plasma peak and a more intense effect, however of shorter duration, followed by the intravenous, respiratory and finally the oral route (Crespo-Fernandez & Rodríguez, 2007). Table 1 shows the pharmacokinetic variables of the different patterns of use as well as their purity in relation to the cocaine content.

Forensic Aspect
Forensic Toxicology is an area oftoxicology that uses fundamentals of analytical chemistry for legal purposes, aiming to obtain material evidence for the Justice. In addition to researching substances in biological materials post-mortem or in living individuals, chemical expertise is also responsible for detecting the composition of samples suspected to belong to For the detection of the presence of cocaine through the rapid test, two techniques are used: Test with the Mayer Reagent and the Scott Test, with modified cobalt thiocyanate reagent. Mayer's reagent is effective for identifying plant alkaloids. Cocaine, being in that chemical group, reacts to form an immediate turbidity of the medium. However, this test has low selectivity, as it reacts positively to other alkaloids such as lidocaine and ecstasy (Bacchi, 2001;Passagli, 2013 (2014).
The Modified Scott test indicates the presence of cocaine in unknown samples, it consists of a solution of cobalt thiocyanate in an acid medium that in contact with samples containing cocaine changes its color from pink to blue. This analysis is widely used as a quick or preliminary test, of great value for the arrest in flagrante offense of the accused of carrying illicit drugs. However, it is mandatory to carry out the definitive test using more specific and robust analytical methods, for final proof of the substance such as cocaine (Passagli, 2013). All physical evidence must follow a Chain of Custody, which is the chronological documentation that records all the legal transit of the sample collected, thus ensuring the veracity of the evidence.
"It is used to maintain and document the chronological history of the evidence1, to track the possession and handling of the sample from the preparation of the collection container, collection, transportation, receipt, storage and analysis, therefore, it refers to the ongoing time in which the sample is being handled and includes all persons handling it. This terminology has been used legally to guarantee the identity and integrity of the sample, in all stages of the process." (Lopes, Gabriel & Bareta, 2006).

Epidemiology and Public Health
Aiming to create a relationship between the facts that occurred and the individuals affected, there is the use of epidemiology in health. From the tracking of diseases such as cholera and AIDS, to the use in criminal analyzes, as proposed here, the association of sociodemographic, statistical and cartographic data contributes to the knowledge of the problem in all its aspects, making possible the geographical delimitation of a population that would be more susceptible to targeted and effective preventive action, indicating the risks, the speed of dissemination of the problem, the priorities of the intervention and mainly, formulating an explanation for the event of the public health problem with scientific basis (Hino, Scatena Villa, Midori Sassaki, Nogueira & Santos, 2006).
Thus, according to Carvalho et al. 2007, the study of the geographic distribution of diseases and conditions and their relationship with socioenvironmental factors constitutes what we call Geographic Epidemiology, which has been constituted in the field of application and development of new methods of analysis.
In Brazil, the problem of drugs is the subject of discussions in various spheres of Public Policy. Attempts to remedy or control the disorder are repeated. Despite the severity, there are few studies that address this issue as a Public Health problem using the Geographic Information System (GIS) combined with spatial analysis.
Historically, the most traditional example of using GIS is the cholera map made in the city of London between 1850 and 1860 by the English physician John Snow. During the cholera epidemic, he realized that the city of London was supplied by two companies: the Lamberth Company and the Southwark and Vauxhall Company. The first received water from the Thames River, located before the municipal sewer, while the second captured water after that point. From the cholera map, it was observed that of the 10,000 houses supplied by the Lamberth Company, 37 deaths occurred, and in the same number of houses supplied by the Southwark and Vauxhall Company, 315 deaths occurred. The map showed the distribution of cholera deaths, presented a spatial pattern of deaths and an association between water supply points and cholera.
Thus, according to Carvalho et al., 2007, the study of the geographic distribution of diseases and conditions and their relationship with socio-environmental factors constitutes the object that we call Geographic Epidemiology, which has been constituted in the field of application and development of new methods of analysis.
Geoprocessing consists of georeferencing data through computer programs that allow the use of maps, topographic maps and plans. When associated with previously collected events, they provide a signal of the risks that the population is exposed to, as well as monitoring the dissemination of this problem (Skaba, Carvalho, Barcellos & Martins, 2004).
There are two types of data that can be used in georeferencing. Point Analysis and Analysis of Geographic Charts.
Point Analysis, which is the simplest type, as it relates the distribution of the event's coordinates with any other variable, noting that the location is random, will be the target of statistical analysis. The Analysis from Geographic Areas, on the other hand, has defined limits, usually political-administrative divisions, such as the district where it occurs, the health district or the State, for example. It is important to remember that geographic differentiation decreases with the increase in the size of the analyzed area and its respective population. This happens due to socioeconomic differences in a given municipality or community (Carvalho, Cruz & Souza, 2007).
Thematic maps are powerful instruments for the spatial analysis of the risk of a specific disease, condition or event, with the objective of describing and allowing visualization of the spatial distribution of the event, suggesting the local determinants and unknown etiological factors that may originate the formulation of hypotheses and point out associations between the event and its determinants.
In Brazil, little is known about the spatial distribution of illicit drug seizures in urban and rural areas. Based on this premise, the present project aims to trace the epidemiological profile of individuals who were seized carrying quantities of cocaine in the municipality of Campina Grande, based on forensic analysis.

Methodology
This was an aggregate, observational (investigator's position), cross-sectional and ecological study based on sociodemographic data and illicit drug seizures. The option for epidemiological studies of the ecological type may be logically adequate for the understanding of risk variation among different population groups. An important approach from an ecological point of view is to consider space as a multidimensional factor of stratification of populations, which allows to visualize spatially, in an articulated way, the distributions of drug seizures and risk. For the study of spatial analysis, data from geographic areas with defined boundaries, usually political-administrative divisions, can be used. Our study chose the area data, more specifically the neighborhood variable (Carvalho, Cruz, & Souza, 2007).
The data were taken from the reports filed by the Campina Grande Forensic Laboratory Nucleus (NULF-CG / IPC) and the files at the Narcotic Court of the District of Campina Grande located at the Afonso Campos Forum.

Research and Population Location
The geographical area studied was the municipality of Campina Grande ( The variables used for the study were related to seasonality (Monthly Distribution), to the visual characteristics of the seized drugs (white colored powder, white colored paste, white colored solid substance, yellow colored solid substance), to the sociodemographic data (gender , age group, marital status, education and situation in the job market and in relation to the neighborhoods of occurrence, this last variable was obtained from the "52 codes" available at the Statistics Department of the Science and Technology Center of Universidade Estadual da Paraíba (Table 2).

Data Processing and Analysis
In data analysis, descriptive statistics was used, using simple absolute and percentage frequencies for categorical variables and organization of results in tables. Then, the chi-square adherence test was applied to verify the suitability of the probabilistic model to the research data. In addition, to verify possible associations between the variables under study, the Chisquare test and Fisher's exact test were used in cases where the expected frequencies were less than 5 (SIEGEL, 2006), considering the significance level of 5% (p <0.05). The analyzes were performed with the aid of the statistical software R (R Core Team, 2019).
Thematic maps were prepared with the aid of Excel spreadsheets and the computer programs of Geographic Information Systems Diva-Gis and Qgis. The coordinates of the apprehension points were collected according to the address contained in the expert reports using Google Maps.

Results and Discussion
In 2017, 210 cocaine seizures were recorded, of which 146 occurred in the municipality of Campina Grande, of which, only 94 presented all the data and were considered in this study (Table 2). Source: Own authorship.
During 2017, the months of September and October presented the highest number of seizures, 14 and 13, respectively.
Sociodemographic variables showed a significant degree of association using the Chi-square test (p> 0.05). The use patterns with the highest incidence were yellowish stone (crack) for respiratory use with 46 seizures and white powder (COC.HCL), for intranasal use, corresponding to 40 seizures. Regarding the framing of the offense, 79.79% were classified as drug trafficking, according to Article 33 of theLaw nº. 11,343 of August 23, 2006 (Table 3). show the profile of the cocaine user / bearer as an individual, male, with low education and no employment relationship (Ferreira Filho et al, 2003;Oliveira and Nappo, 2008).
For the evaluation of the specific variable DELIT, divided into size and traffic, the Fisher's exact test in cases where the expected frequencies were less than five, in relation to gender, education and pattern of use, with no association between variables (p <0.05) ( Table 4).
In the geospatial analysis of data from the neighborhood areas of Campina Grande City, the number of seizures was divided into quartiles and distributed on a map according to the number of seizures and the neighborhood of occurrence. Due to the high number of neighborhoods (n = 23), which did not obtain any records of apprehension, the division into quartiles was impaired, and the question remains whether the absence of apprehensions in these neighborhoods was due there were no crime or a failure in the notification, losing valuable information for tracking the phenomenon of cocaine trafficking and consumption in the municipality.  Source: Own authorship.
In a study conducted by Silva e Chao (2009) in the city of Campina Grande, specifically in the neighborhood Zé Pinheiro, it was found that despite being one of the oldest neighborhoods and with the second largest trade in the city, violence is a problem that deflates the lives of the people who live there. The gangs and organized crime groups that have occupation there threaten and make it difficult to hold cultural events and social projects, since the people feel prevented from using some public spaces due to the lack of security and because they feel threatened by the criminal organizations that command the place. Often, spaces such as squares and sports courts become trafficking points in the hands of criminals, preventing the free access of people and residents.
According to the Moran Scattering Graph (Figure 3), analytically in 2017, it can be seen that there is no cause and effect relationship between the neighborhoods, that is, the number of cocaine seizures in a neighborhood X does not affect the distribution in surrounding neighborhoods, that is, seizures happen at random. This data was confirmed by the Spatial Autocorrelation Test or General Moran Index (Table 3) and by the Local Moran Index, according to each neighborhood individually (Table 4). These tests showed no significant correlation between neighborhoods.  Source: Own authorship. The analysis of the geoprocessing of cartographic points is demonstrated in the Points map ( Figure 4). It is observed through this map, once again, that there is a randomness present in these seizures, highlighting the cluster present in district 01, corresponding to the locality of the José Pinheiro neighborhood, which accounted for the largest number of cocaine seizures this year (n = 15).

Final Considerations
In this study, it was possible to establish the profile of the individual cocaine user or dealer in the municipality of Campina Grande as being predominantly young male, single, with elementary education and unemployed. Beyond the profile of the seized drug and its predominant place of seizure, we have cocaine in its yellowish stone form (crack) and white colored powder as the most seized and the neighborhoods that presented the greatest quantity of cocaine seizures in Campina Grande in 2017 were José Pinheiro and Pedregal. Marginalized neighborhoods with high personal vulnerability, however, it was proved by the Autocorrelation Test, these neighborhoods do not influence others in the surrounding area, so the cocaine seizures that occurred in 2017 in the municipality of Campina Grande occurred at random.
There was a deficit in the registration of sociodemographic data in the initial reports of the individual was caught with possession of narcotics, making it difficult to report, track and determine a profile of drug use in the city of Campina Grande.
