Trends in the use of psychoactive substances by truck drivers in São Paulo State, Brazil: A time-series cross sectional roadside survey (2009-2016).

OBJECTIVE: Truck drivers represent a group that is susceptible to the use of stimulant substances to reduce the symptoms of fatigue, which may be caused by a stressful and exhausting work environment. The use of psychoactive substances may increase the risk for involvement in road traffic crashes. Previous studies have demonstrated that amphetamine, cocaine, and cannabis are the 3 main drugs used by Brazilian truck drivers. We studied the prevalence of amphetamine, benzoylecgonine (indicating use of cocaine), and Δ-9-tetrahydrocannabinol-9-carboxylic acid (THC-COOH; indicating use of cannabis) in urine samples from truck drivers in the state of São Paulo, Brazil, using the same methodology during 8 years (2009-2016). METHODS: Samples were collected during a health program supported by the Federal Highway Police. Toxicological analyses were performed using immunoassays and gas chromatography-mass spectrometry. RESULTS: The total prevalence of illicit drugs was 7.8%. Benzoylecgonine was the most prevalent substance (3.6%), followed by amphetamine (3.4%) and THC-COOH (1.6%). We found the highest drug prevalence in 2010 (11.3%) and the lowest in 2011 (6.1%). We could detect a slight change in the pattern of stimulant use: until 2010, amphetamine was the most prevalent substance; however, in 2011 benzoylecgonine became the most frequently detected substance. This lasted until 2015, probably due to changes in Brazilian legislation regarding appetite suppressants; the most common one is metabolized to amphetamine. CONCLUSION: These data show that the use of psychoactive substances by truck drivers in Brazil did not decrease during the study period. This reinforces the need for further preventive measures to reduce drug use among drivers, which could lead to a decrease in traffic crashes in Brazil.

Association between travel length and drug use among Brazilian truck drivers.

OBJECTIVE: To investigate whether the use of the stimulants amphetamines and cocaine by truck drivers in Brazil was related to travel length. METHODS: Truck drivers were randomly stopped by the Federal Highway Police on interstate roads in Sao Paulo State during morning hours from 2008 to 2011 and invited to participate in the project "Comandos de Saúde nas Rodovias" (Health Commands on the Roads). Participants were asked about the use of drugs, travel distance, and age, and gender was recorded. Samples of urine were collected and analyzed for amphetamine, benzoylecgonine (a metabolite of cocaine), and carboxytetrahydrocannabinol (THC-COOH; a metabolite of cannabis) by immunological screening and quantification by gas chromatography-mass spectroscopy. RESULTS: Current use of amphetamine, cocaine, and cannabis was reported by 5.7%, 0.7%, and 0.3% of the truck drivers, respectively. Amphetamine, benzoylecgonine, and THC-COOH were found in urine samples from 5.4%, 2.6,% and in 1.0% of the drivers, respectively. There was a significant association between the positive cases for amphetamine and reported travel length; 9.9% of urine samples from drivers who reported travel length of more than 270 km were positive for amphetamine, and 10.9% of those drivers reported current use of amphetamines. In most cases, appetite suppressants containing amphetamines had been used, but the purpose was most often to stay awake and alert while driving. Truck drivers with travel length of more than 270 km had significantly higher odds ratio (OR) for having a urine sample that was positive for amphetamine when adjusted for age as confounding factor (OR = 9.41, 95% confidence interval [CI], 3.97-22.26). No significant association was found between the use of cocaine or cannabis and travel length. CONCLUSION: Truck drivers who reported driving more than 270 km had significantly higher frequencies of urine samples positive for amphetamine and reported significantly more frequent current use of amphetamines than those who reported shorter driving distances.

Uso de substâncias psicoativas por motoristas profissionais no Estado de São Paulo / Psychoactive substances use by profesional drivers in São Paulo State

No mundo os acidentes de trânsito são responsáveis pela morte de aproximadamente 1,2 milhão de pessoas por ano. No Brasil, em 2014, foram mais de 44 mil óbitos no trânsito. O uso de substâncias psicoativas na direção é considerado um importante fator contribuinte para a ocorrência destes acidentes. Além do álcool, as drogas ilícitas mais utilizadas em nosso país são a anfetamina, a cocaína e a cannabis. As anfetaminas e a cocaína são utilizadas por motoristas de caminhão, que consomem para se manterem acordados por muitas horas e estão propensos a dormir ao volante. Portanto, há necessidade de conhecer o problema para que as autoridades competentes possam implementar políticas públicas relacionadas ao uso de drogas por motoristas e assim, minimizar os acidentes de trânsito no Brasil. Objetivo: Avaliar a prevalência do uso de substâncias psicoativas (anfetaminas, cocaína e cannabis) entre motoristas de caminhão que trafegavam em rodovias do Estado de São Paulo, através de análises toxicológicas em urina e correlacionar com dados sociodemográficos e ocupacionais. Métodos: Trata-se de estudo observacional do tipo transversal e a coleta dos dados foi realizada entre os anos de 2008 e 2012. Participaram do estudo 1.316 motoristas que, após assinarem o termo de consentimento livre e esclarecido e responderem a um questionário sobre dados sociodemográficos e ocupacionais, forneceram uma amostra de urina. Essas amostras foram analisadas por imunoensaio e por cromatografia em fase gasosa acoplada à espectrometria de massas. Resultados: Das amostras coletadas, 7,8% (n=103) apresentaram resultados positivos para uma ou mais drogas pesquisadas e/ou seus metabólitos, dos quais 3,4% foram resultados positivos para anfetamina, 2,8% para cocaína e 1,1% para cannabis. O 0,5% restante correspondeu aos casos com mais de uma droga. Com exceção do ano de 2008, as três drogas pesquisadas foram encontradas em todos os anos da pesquisa. Os resultados das análises...

Traffic accidents are responsible for approximately 1.2 million deaths per year worldwide. In Brazil, there were more than 44,000 traffic-related deaths in 2014. The use of psychoactive substances while driving is considered a major contributing factor to the occurrence of these accidents. In addition to alcohol, the most used illicit drugs in our country are amphetamines, cocaine and cannabis. Amphetamines and cocaine are commonly used by truck drivers to stay awake for several hours because they are likely to sleep while driving. Therefore, it is necessary to understand better this problem in order to help authorities implement public policies related to drug use by drivers and thus minimize traffic accidents in Brazil. Objective: To evaluate the prevalence of psychoactive substance (amphetamines, cocaine and cannabis) use among truck drivers in the highways of the State of Sao Paulo by toxicological analysis in urine and to correlate it with sociodemographic and occupational data. Methods: This is an observational cross-sectional study in which data collection was carried out between 2008 and 2012. This study included 1,316 drivers who provided a urine sample after signing a consent form and answering to a questionnaire with sociodemographic and occupational data. The urine samples were analyzed by immunoassay and gas chromatography-mass spectrometry. Results: Of the total samples collected, 7.8% (n = 103) were positive for one or more tested drugs and/or its metabolites, with 3.4% positive for amphetamine, 2.8% for cocaine and 1.1% for cannabis. The remaining 0.5% corresponded to cases with more than one drug. The three drugs were found during most of the study period, except in 2008. Toxicological findings were distributed differently according to some variables: age, employment period and marital status were associated with drug use, while the employment type, ethnicity and education were not. Travel length and night rest period were also...

[Persistent amphetamine consumption by truck drivers in São Paulo State, Brazil, despite the ban on production, prescription, and use]. / A continuidade do uso de anfetaminas por motoristas de caminhão no Estado de São Paulo, Brasil, a despeito da proibição de sua produção, prescrição e uso.

Amphetamine use by truck drivers for occupational purposes is widely known. The production and consumption of amphetamines was banned by the Brazilian National Health Surveillance Agency (ANVISA) in October 2011. This study analyzes persistent amphetamine use by truck drivers since the ban was implemented. A convenience sample of 427 truck drivers was taken along highways in São Paulo State in 2012. Participants were asked to answer a structured questionnaire and provide a urine sample to screen for recent amphetamine consumption through toxicological analysis. Among the interviewed drivers, 7% had used some illicit drug recently and 2.7% had used amphetamines. Amphetamines are still consumed by truck drivers despite the risks and the recent ban. The authorities should thus monitor the possession and use of amphetamines by drivers in order to effectively enforce the ban.

O uso de anfetaminas por motoristas de caminhão com fins ocupacionais é amplamente reconhecido, entretanto, no mês de outubro de 2011, sua produção e uso foram proibidos através de uma resolução da Agência Nacional de Vigilância Sanitária (ANVISA). O objetivo deste estudo foi identificar o uso de anfetaminas entre motoristas de caminhão após a implementação da referida resolução. Uma amostra de conveniência de 427 motoristas de caminhão foi abordada em rodovias do Estado de São Paulo, Brasil, durante o ano de 2012. Os participantes foram solicitados a responder um instrumento de pesquisa estruturado, assim como fornecer uma amostra de urina para avaliar o uso recente de anfetaminas através de análise toxicológica. Entre os motoristas avaliados, 7% fizeram uso recente de alguma substância ilícita, dos quais 2,7% usaram anfetaminas. Aparte a periculosidade associada ao uso de anfetaminas, assim como a despeito da resolução que o regulamenta, esse uso continua entre os motoristas de caminhão. Assim, sugere-se que as autoridades competentes fiscalizem a posse, assim como o uso de anfetaminas no contexto do trânsito.

El uso de anfetaminas con fines profesionales entre los conductores de camiones es ampliamente reconocido, sin embargo, en octubre de 2011, su producción y uso fueron prohibidos por una resolución de la Agencia Nacional de Vigilancia Sanitaria (ANVISA). El objetivo de este estudio fue identificar el uso de anfetaminas entre conductores de camión después de la implementación de esa resolución. Una muestra de conveniencia compuesta por 427 conductores de camiones fue abordada en las carreteras del estado de São Paulo, Brasil, en el año 2012. A los participantes se les pidió rellenar una encuesta estructurada, así como dar una muestra de orina para determinar el consumo reciente de anfetaminas, a través de análisis toxicológico. Entre los conductores evaluados, el 7% consumió recientemente algún estupefaciente, de los cuales un 2,7% había consumido anfetaminas. Aparte de los peligros asociados al uso de anfetaminas, y de la resolución que lo regula, ese uso sigue vigente entre los conductores de camión. Por lo tanto, se sugiere que las autoridades competentes supervisen la posesión, así como el consumo de anfetaminas, en el tráfico rodado.

Uso de álcool por vítimas de morte violenta no Estado de São Paulo (PAP)

As mortes por causas externas se constituem em um dos mais importantes problemas de saúde pública e, entender com maior profundidade esta questão é elemento crucial para fundamentar políticas efetivas. O segmento populacional mais vulnerável à incidência de tais mortes é a população jovem masculina. Entre os fatores de risco apontados para a alta mortalidade dentre as causas externas, encontra-se o uso do álcool, que é a droga lícita mais consumida pela população. Entre outros efeitos, o álcool etílico diminui a capacidade cognitiva, aumenta a probabilidade de respostas agressivas e prejudica a atenção e capacidade de julgamento, tornando o indivíduo mais vulnerável à vitimização por violência e acidentes. O objetivo deste estudo foi conhecer a provável relação entre o consumo de álcool e a ocorrência de mortes violentas, a partir da coleta de dados dos laudos necroscópicos de vítimas necropsiadas em diversos postos médico-legais do Estado de São Paulo, no ano de 2006. Foram obtidos dados de 12.926 vítimas e constatou-se que 36,9% delas estavam alcoolizadas no momento do óbito, enfatizando a existência de uma estreita relação entre a ocorrência de mortes violentas e o consumo de álcool. Os níveis de alcoolemia mais observados estavam entre 0,6 a 2,5 g/l, com média geral de 1,8 ± 1,0 g/l. A faixa etária com maior número de vítimas foi a de 20 a 29 anos com médiade 36 ± 16 anos. O sexo masculino representou 86,4% do total; destes, 39% apresentaram alcoolemia positiva, enquanto em apenas 21% das mulheres houve essa positividade. Entre os homens predominaram os homicídios, enquanto entre as mulheres predominaram os acidentes de trânsito. Entre as causas de morte, a maior prevalência foi do grupo de mortes a esclarecer e outras, somando 45,2% do total. Acidentes de trânsito representaram 25,2% das causas e em seguida os homicídios com 24,5%. Os suicídios representaram apenas 5,1%. As causas de mortes foram diferencialmente...
