- The role of drug use sequencing pattern in further problematic use of alcohol, tobacco, cannabis, and other drugs(2015) CASTALDELLI-MAIA, Joao Mauricio; MARTINS, Silvia S.; OLIVEIRA, Lucio Garcia de; ANDRADE, Arthur Guerra de; NICASTRI, SergioBackground: There has been considerable debate regarding what typically occurs after experimentation with drugs throughout the life of young people who used various drugs. Aims: To evaluate the clinical importance of the most common sequence for the first use of a drug by two models (the ""gateway model'' and the ""alternative model'', which is the most popular sequence for Brazilian university students according to a previous study) regarding the problematic use of alcohol, tobacco, cannabis and other illegal drugs, assessed by ASSIST. Method: People who had already experimented with three or more drugs across different stages of the two models were selected from a representative sample of university students from 27 Brazilian capitals (n = 12 711). Findings: There were no differences regarding the problematic use of the most consumed drugs in Brazil (alcohol, tobacco and cannabis) between the models. Multiple drug seekers and violators had more problematic use of illegal drugs other than cannabis than individuals in the model sequence. However, in the case of violators, this was only evident in the alternative model. Conclusions: Multiple drug seekers and violators deserve special attention due to their increased risk of problematic use of other illegal drugs.
- Alcohol use alone and in combination with other drugs among truck drivers on highways in Sao Paulo State, Brazil: a cross-sectional study(2015) LEOPOLDO, Kae; LEYTON, Vilma; OLIVEIRA, Lucio Garcia deTraffic accidents cause more than a million deaths per year worldwide. Brazil is one of the leading countries in traffic accidents. Since alcohol is a known etiological factor for traffic accidents, the pattern of alcohol use alone and in combination with other drugs was assessed in a convenience sample of 684 truck drivers in Sao Paulo State, Brazil. 67.3% of participants reported alcohol use in the previous 30 days, 34.6% reported heavy drinking, 26% binge drinking, and 9.2% were at risk of developing alcohol addiction. Furthermore, 54.6% reported multiple drug use, mostly alcohol with tobacco and energy drinks. Truck drivers that reported multiple drug use showed heavier alcohol use than those who consumed only alcohol. Drinking and driving is problematic and can be aggravated by multiple drug use. The authors thus suggest monitoring the issue, which creates serious problems for users and society as a whole.
- Occupational conditions and the risk of the use of amphetamines by truck drivers(2015) OLIVEIRA, Lucio Garcia de; SOUZA, Leticia Maria de Araujo de; BARROSO, Lucia Pereira; GOUVEA, Marcela Julio Cesar; ALMEIDA, Carlos Vinicius Dias de; MUNOZI, Daniel Romero; LEYTON, VilmaOBJECTIVE: To test whether the occupational conditions of professional truck drivers are associated with amphetamine use after demographic characteristics and ones regarding mental health and drug use are controlled for. METHODS: Cross-sectional study, with a non-probabilistic sample of 684 male truck drivers, which was collected in three highways in Sao Paulo between years 2012 and 2013. Demographic and occupational information was collected, as well as data on drug use and mental health (sleep quality, emotional stress, and psychiatric disorders). A logistic regression model was developed to identify factors associated with amphetamine use. Odds ratio (OR; 95% CI) was defined as the measure for association. The significance level was established as p < 0.05. RESULTS: The studied sample was found to have an average age of 36.7 (SD = 7.8) years, as well as low education (8.6 [SD = 2.3] years); 29.0% of drivers reported having used amphetamines within the twelve months prior to their interviews. After demographic and occupational variables had been controlled for, the factors which indicated amphetamine use among truck drivers were the following: being younger than 38 years (OR = 3.69), having spent less than nine years at school (OR = 1.76), being autonomous (OR = 1.65), working night shifts or irregular schedules (OR = 2.05), working over 12 hours daily (OR = 2.14), and drinking alcohol (OR = 1.74). CONCLUSIONS: Occupational aspects are closely related to amphetamine use among truck drivers, which reinforces the importance of closely following the application of law (Resting Act (""Lei do Descanso""); Law 12,619/2012) which regulates the workload and hours of those professionals. Our results show the need for increased strictness on the trade and prescription of amphetamines in Brazil.
