Abstract:
(+)-Amphetamine and two structurally related analogues, 4-methoxyamphetamine and a recent "designer drug," 4-ethoxy-amphetamine, were given to rats via subcutaneous osmotic minipumps for 1–14 days. Regional brain levels of the drugs as well as monoamine neurotransmitters and some of their major acidic metabolites were determined. Amphetamine produced depletions of dopamine in the striatum after at least 3 days of treatment but not in the nucleus accumbens or olfactory tubercle, even after 14 days of treatment. In contrast, the two ring-substituted amphetamine analogues increased levels of the monoamines and decreased levels of their acid metabolites. These data indicate that the two ring-substituted amphetamine analogues, at least one of which is a potent hallucinogen, have potent monoamine oxidase inhibition properties that are sustained during chronic treatment. Furthermore, these two compounds do not share amphetamine's regionally selective neurotoxic effects on dopamine-releasing terminals, even though brain and striatal drug levels are the same or higher than those of amphetamine.Key words: (+)-amphetamine, 4-methoxyamphetamine, 4-ethoxyamphetamine, designer amphetamines, monoamines, rats, chronic treatment.

Abstract:
BACKGROUND: Amphetamine and amphetamine-type stimulants are powerful physical and psychostimulants; they are phenethylamine derivatives. The use of amphetamines can be either medicinal or illicit. Several amphetamines have been redesigned into illegal drugs of potent properties, also known as research chemicals and designer drugs. Hence, they are named novel (new) psychoactive substances (NPS).MATERIALS & METHODS: This study is a hybrid study of; data crunching and retrospective analysis of a trends database (1), and a systematic review of literature in relation to the amphetamines-induced adverse effects on the cardiovascular system (2). Google Trends database has been analysed in retrospect (2012-2017) to evaluate the attentiveness of surface web users towards amphetamine and a potent renowned amphetamine derivative known as captagon (fenethylline).RESULTS: Amphetamines appear to be highly popular worldwide, particularly in the developed world including North America and European countries, and to a less extent in the developing countries including the Middle East. However, the trends are oscillating with time with significant year-to-year changes although there was some steadiness in the temporal patterns (trends), for example in 2013-2014 (p-value=0.258). Variations in the trends were found to be correlated with global events including international terrorism. The adverse effects of amphetamines were found to be highly related to the cardiovascular system with a high incidence of intoxications and deaths among substance (ab)users.CONCLUSION: Several amphetamines are potent and used illicitly beyond their original therapeutic potential, as in the case of captagon, culminating in monumental public and economic threats. Legalising bodies should exercise tremendous and systematic efforts to counteract these threats. Database analyses can provide an accurate insight into this phenomenon that has been growing exponentially in the past decade.

Abstract:
Abstract Background: Immunoassay-based screening for amphetamines has a variable positive predictive value (PPV) for detecting amphetamine abuse. The lack of immunoassay specificity necessitates confirmatory testing by gas chromatography–mass spectrometry (GC/MS), but the technical complexity and expense of GC/MS limit its availability. Physicians may make decisions regarding patient disposition based on unverified results. In this study we assessed the utility of using dose–response properties to distinguish urine samples containing amphetamines from samples containing cross-immunoreactive species. Methods: Urine was supplemented with known concentrations of amphetamine, methamphetamine, methylenedioxymethamphetamine (MDMA), or pseudoephedrine. Using a series of dilutions, we determined the maximum change in rate over the fractional change in concentration for each compound in the Emit® II amphetamine/methamphetamine immunoassay. Patient urine samples that screened positive for amphetamines were diluted 1:1, 1:10, and 1:20, and maximum slope estimates within the dynamic assay range were determined. An optimal slope cutoff that differentiated samples containing (meth)amphetamine from those containing cross-reacting species was determined by ROC analysis. Results: The slope of the dose response was largest for amphetamine and methamphetamine, followed by MDMA and pseudoephedrine. The optimum slope cutoff for identifying patient specimens containing (meth)amphetamine was 320 (sensitivity, 96%; specificity, 90%; PPV, 92%). High concentrations of less reactive compounds may mask low concentrations of amphetamines. Conclusions: Use of the slope of the dose–response relationship in patient urine specimens can enhance the PPV of presumptive positive immunoassay results but does not exclude the presence of low amphetamine concentrations in samples containing high concentrations of cross-reactive species.

Abstract:
Background: Spontaneous spinal epidural hematoma (SSEH) is a rare condition that is typically associated with hypertension, the use of antithrombotic or sympathomimetic drugs. Here, we report a case of SSEH attributed to the use of amphetamines. Case Description: A 27-year-old amphetamine user presented with the sudden onset of paraplegia (Frankel A) following amphetamine use. An MRI revealed C7–T2 spinal cord compression due to an epidural hematoma. Following a negative angiogram, the SSEH was removed, and the patient markedly recovered. Notably, by exclusion, the etiology for the SSEH was attributed to the use of amphetamines. Conclusion: Here, we demonstrate the case of a 27-year-old male who presented paraplegic due to an acute C7– T2 SSEH secondary to amphetamine abuse.

Abstract:
Amphetamine abuse is a known problem in Saudi Arabia; it is estimated that 40% of drug abusers misuse amphetamines. Here, our aim was to perform an up-to-date epidemiological study of amphetamine-related postmortem cases in Jeddah, Saudi Arabia, in which 235 postmortem cases were included. The largest number of cases was recorded for the groups aged between 31 and 40 years (86 cases) and the lowest number of cases was recorded for the group aged between 61 and 70 years old (5 cases). Amphetamine was co-ingested with other drug(s) in 55% of the total cases (blood with sodium fluoride (BN), median, 0.3 mg/L). Approximately 23% of all deaths were due to other co-ingested drugs (BN, median, 0.2 mg/L). Amphetamines alone were detected in 107 cases, (BN, median, 0.5 mg/L). Amphetamine was the sole cause of death in 16% of the studied cases (BN, median, 1.0 mg/L). The combination of amphetamine and a pre-existing disease were observed in 9.4% of all deaths (BN, median, 0.7 mg/L). The causes of death were determined to be accidental in the majority (47%) of cases, homicides in 26% of cases, suicides in 11% of cases, and unknown in 7% of cases. This is the first discussion of the amphetamine concentration in bile in amphetamine-related deaths, the relationship between amphetamine concentration in different bodily fluids, and the amphetamine concentration in putrefied corpses. This study concluded that amphetamine abuse in Jeddah, Saudi Arabia, increased over 400% between 2012 and 2018, and 41% of these cases involved violence. This result also suggests that preventive programs targeting youth and adolescent students are required to keep schools and universities free from drugs, especially amphetamines.

Abstract:
Aims and MethodThis study aimed to assess the current level of amphetamine prescribing for adults in drug services in the West and East Midlands. A questionnaire was developed to investigate prescribing habits and attitudes, and was addressed to the senior member of staff in each drug service within the West and East Midlands area.ResultsA total of 41 services were identified, and 29 questionnaires were returned (a 71% response rate). Of the services that replied, 20 (69%) prescribed amphetamines, with 132 (12%) patients identified as amphetamine misusers currently receiving a prescription. However, 26 (90%) services felt that substitute prescribing did have a role in a comprehensive service for this group.Clinical ImplicationsAlthough amphetamine prescribing has been shown to reduce both criminal and injecting behaviour, only two-thirds of the local services prescribe such drugs, with a small percentage of amphetamine users receiving a prescription. There is a need for a national consensus about substitute prescribing of amphetamines and increased flexibility within drug services when managing the problem.

Abstract:
OBJECTIVE: To analyze drug use trends among college students in 1996, 2001 and 2009. METHODS: A cross-sectional epidemiological study with a multistage stratified cluster sample with 9,974 college students was conducted in the city of São Paulo, southeastern Brazil. An anonymous self-administered questionnaire was used to collect information on drug use assessed in lifetime, the preceding 12 months and the preceding 30 days. The Bonferroni correction was used for multiple comparisons of drug use rates between surveys. RESULTS: There were changes in the lifetime use of tobacco and some other drugs (hallucinogens [6.1% to 8.8%], amphetamines [4.6% to 8.7%], and tranquilizers [5.7% to 8.2%]) from 1996 to 2009. Differences in the use of other drugs over the 12 months preceding the survey were also seen: reduced use of inhalants [9.0% to 4.8%] and increased use of amphetamines [2.4% to 4.8%]. There was a reduction in alcohol [72.9% to 62.1%], tobacco [21.3% to 17.2%] and marijuana [15.0% to 11.5%] use and an increase in amphetamine use [1.9% to 3.3%] in the preceeding 30 days. CONCLUSIONS: Over the 13-year study period, there was an increase in lifetime use of tobacco, hallucinogens, amphetamines, and tranquilizers. There was an increase in amphetamine use and a reduction in alcohol use during the preceding 12 months. There was an increase in amphetamine use during the preceding 30 days.

Abstract:
Abstract Amphetamines, frequently used recreational drugs with high risk of toxicity, are commonly included in urine drug screens. This screening is based on enzyme immunoassay, which is a quick and easy-to-perform technique, but may lack specificity resulting from cross-reactivity with other compounds, causing false positive results. We present two cases of presumed false positive MULTIGENT® amphetamine/methamphetamine and MULTIGENT® ecstasy (Abbott®) immunoassays with the beta-blocker metoprolol. Both metoprolol-poisoned patients presented positive urine screening despite no history of drug abuse. No confirmation for amphetamine molecular structures was found with gas chromatography–mass spectrometry. The cross-reactivity was further investigated by doping urine samples with metoprolol and its two major phase-I metabolites. Metoprolol showed positive results for both amphetamine and MDMA tests at low concentrations (200 and 150 μg/mL, respectively). Metoprolol metabolites cross-reacted with the amphetamines immunoassay only, but at higher concentrations (i.e., 2000 μg/mL for α-hydroxymetoprolol and 750 μg/mL for O-demethylmetoprolol). In conclusion, false positive results in amphetamines and MDMA immunoassays are possible in the presence of metoprolol. Toxicologists should be aware of frequent analytical interferences with immunoassays and a detailed medication history should be taken into consideration for interpretation. In vitro investigation of suspected cross-reactivity should include not only the parent drug but also its related metabolites.

Abstract:
As anfetaminas conhecidas como "rebites" são normalmente utilizadas por caminhoneiros. Este estudo teve como objetivo verificar a prevalência e fatores associados à utilização autorrelatada de anfetaminas entre caminhoneiros que trafegam na rodovia BR 251, no trecho de Montes Claros, MG, com parada em um posto de combustível. Trata-se de um estudo transversal, quantitativo com seleção dos indivíduos por amostragem de conveniência. Foi utilizado um questionário com dados sociodemográficos, econômicos, ocupacionais e relacionados às anfetaminas. Realizou-se a análise bivariada, cuja variável dependente foi o uso de anfetaminas e aquelas que apresentaram associação ao nível de 20% (p≤0,20) foram selecionadas para a análise múltipla utilizando a Regressão de Poisson. Permaneceram no modelo as variáveis com desfecho ao nível de 5% (p≤ 0,05). Dentre os 306 pesquisados, 22,2% eram usuários de anfetaminas, sendo o princípio ativo mais utilizado o Femproporex (Desobesi®). A média de idade foi de 41 anos, variando de 22 a 77 anos. A maioria trabalha mais de 10 horas diárias. O uso de anfetaminas esteve associado aos profissionais mais jovens e com maior carga horária de trabalho. Faz-se necessário um controle maior sobre a venda desses medicamentos por parte dos órgãos competentes.Palavras-chave: Prevalência. Anfetaminas. Drogas Ilícitas. FACTORS ASSOCIATED WITH THE AMPHETAMINES USE AMONG TRUCK DRIVERSABSTRACT: Amphetamines known as "rivets" are commonly used by truck drivers. This study aimed to verify the prevalence and factors associated with the self-reported use of amphetamines among truck drivers who travel on the BR 251 highway, in the Montes Claros stretch, MG, stopping at a fuel station. It is a cross-sectional, quantitative study with selection of individuals by convenience sampling. A questionnaire with socio-demographic, economic, occupational and amphetamine-related data was used. The bivariate analysis was performed, whose dependent variable was the use of amphetamines, and those that showed association at the level of 20% (p≤0.20) were selected to multiple variety analysis using Poisson Regression. Remain in analysis only variables whose end point was 5% (p≤0.05). Among 306 participants, 22.2% had used amphetamine, Femproporex (Desobesi®)was the most common active principle used. Mean age was 41 years, range 22 to 77 years old. Most interviewed works more than 10 hours a day. Younger drivers and more daily hours of work were associated with amphetamine use. Finally, to decrease amphetamine use and abuse, it is essential a closer sale control on this drugs by the government.Keywords: Prevalence. Amphetamines. Illicit Drugs.

Abstract:
The current study utilised data collected from the Australian Institute of Criminology’s project known as Drug Use Monitoring in Australia (DUMA). The DUMA project examined detainees’ social demographics and past and present drug use, at various Australian sites. The current study examined secondary data as a subset of the DUMA data collected from the East Perth lockup in Western Australia. Three sections of the DUMA data were analysed in this study (i) changes in amphetamine use by detainees (ii) demographic profile of detained amphetamine users and (iii) offences for which they have been detained. Analyses included chi-square tests, Kendall’s tau_b, ANOVA, and descriptive statistics, which were used in order to ascertain if a change between the three main sections had occurred overtime (1999-2006). Results showed detainees’ amphetamine use increased during the ‘heroin drought’. The profile demographic of detainee amphetamine users showed some significant changes overtime; a majority were male, aged between 18 to 34 years, and most likely to be unemployed. The study also showed detainee amphetamine users were most likely to commit offences against property, rather than offences against a person. Recommendations include detainees be offered drug counselling where appropriate and have access to resources assisting with gaining long-term employment.

Abstract:
Recently, several novel technologies have emerged with substantial benefits in toxicological analysis. These include the development of beadbased multiplex immunoassay (Suspension Bead Array, SBA), the use of reduced-volume centrifugal ion-exchange extraction (SpinSPE), and Ultra-Performance (TM) liquid chromatographic separation coupled to mass spectrometry (UPLC(TM)/MS n ). This work sought to investigate the efficacy and practicality of these innovative approaches against a benchmark of established methods and instrumentation for the screening and confirmation of amphetaminetype substances. This study begins with a statistical survey of amphetaminetype substances encountered in an accredited forensic laboratory supporting the Australian Capital Territory and regional New South Wales. Over the 5year period 2001-2005, it was determined that 6683 case submissions required presumptive screening for amphetamines. Of these cases, 1269 (19.0%) required confirmative analysis of amphetaminetype substances, including amphetamine, methamphetamine, MDA, MDMA, MDEA, ephedrine, pseudoephedrine, and phentermine. Such analytical needs were then used in comparative assessment of the novel and established methodologies, including examination of immunoassay specificity, extraction efficiency, chromatographic resolution, general resource efficiency, and total analysis time. Development of a beadbased immunoassay platform (SBA) for multiplex amphetamines analysis proved to be a complex task. Efforts to multiplex the amphetamine and methamphetamine immunoassay models into a single assay exhibited a significant degree of non-specific antibody cross-reactivity. However, the merits of the individual bead assays were demonstrated. Upon comparison with commercially available enzyme-linked immunosorbent assays for amphetamine or methamphetamine (ELISA), it was observed that the SBA models exhibited specificity comparable to that of the ELISA assays and linearity over a concentration range of toxicological relevance (0-1000 ng/mL amphetamine or methamphetamine). In addition, the results indicated the practical applicability of the individual SBA assays for an oral fluid matrix, and demonstrated significant reductions in the volumes of reagents required and length of time of analysis. Additionally, in an optimised multiplex system, the amount of sample required for screening could be reduced as the SBA technology theoretically permits analysis of up to 100 different drugs or metabolites from one volume of sample. The aspect of forensic sample conservation was further explored with investigation of reduced-volume extraction techniques, such as the application of centrifugal ionexchange extraction columns (SpinSPE). Following initial development, the SpinSPE technique was applied to the isolation of amphetaminetype substances from oral fluid and compared with a mixedmode SPE method for both extraction and resource efficiency. From the observed results, both extraction methods were demonstrated to be effective in the isolation of amphetamine, methamphetamine, ephedrine, pseudoephedrine, PMA, MDA, MDMA, MDEA, MBDB, and 2CB from an oral fluid matrix with detection by heptafluorobutyric acid derivatisation (HFBTA) and GC/MS. The SpinSPE model demonstrated comparable efficacy with reduced sample volume (200 쌩, as well as significant reductions in the volumes of reagents required for column conditioning, washing, and elution. In addition, the linear working range (0-2000 ng/mL) and sensitivity of the method indicated the potential to further reduce sample volume. In the confirmative separation and identification of drug compounds, the technological advancement of UltraPerformance (TM) liquid chromatography (UPLC(TM)) has recently evolved from efforts to improve LC resolution, sensitivity, and time of analysis. In this research, UPLC(TM) coupled to mass spectrometry was demonstrated to be capable of rapidly identifying several amphetaminetype substances (phenylethylamine, amphetamine, phentermine, methamphetamine, ephedrine, pseudoephedrine, PMA, 4MTA, MDA, MDMA, MDEA, MBDB) and ketamine in an analysis time of less than five minutes. In addition, UPLC(TM)/MS demonstrated a resolving power comparable to GC/MS with significantly reduced instrumental analysis time. This research reveals the promise of these new applications in advancing towards a more efficient and modernised systematic toxicological approach. The continued development and optimisation of SBA multiplex immunoassays will permit customisable systems capable of simultaneously detecting numerous compounds with antibodybased sensitivity and selectivity. In circumstances where low sample volumes are required for confirmation of drug use, such as in roadside saliva drug testing for driving under the influence offences, reducedvolume SpinSPE has been demonstrated to be a practical and effective alternative for sample preparation. In addition, a more streamlined procedure is further enhanced with the use of UPLC(TM) coupled to mass spectrometry for analyte separation and molecular identification. It is expected that illicit drug use will remain a significant public concern. With the continued desire for more rapid and comprehensive methodologies, further study of these and other innovative technologies will be of considerable future benefit to laboratories such as that serving the Australian Capital Territory region.

Abstract:
The use of psychoactive substances has been on the rise around the world. Psychoactive substances, such as amphetamine, codeine, cocaine, marijuana, methamphetamine, etc. have potent pharmacological activities that cause cognitive and behavioral disorders. New psychoactive substances (NPSs) have also emerged that produce similar effects to those induced by illegal drugs, such as cocaine, cannabis, and amphetamines, but are not strictly regulated by international conventions. The rapid emergence since the mid-2000s of a large and diverse range of substances termed new psychoactive substances originally designed as legal alternatives to more established illicit drugs has challenged traditional approaches to drug monitoring, surveillance, control, and public health responses. Drug testing is an application used for detected substance use or abuse evaluation processes. As substance use affects human health and safety for not only the person who uses the substance, but also the people around him who do not use it in workplace areas. Therefore, drug testing is used in clinical and forensic purposes in employment, educational, and legal settings. These tests ensure that employers and employees comply with the legal regulations while also helping to lessen business accidents and workplace crime, improve business quality and productivity, and promote drug use avoidance. There have been many scientific, technical, and legal challenges to the validity of urine drug testing. This paper presents definitional information on the terms of psychoactive substances use, legislation of drugs and explores challenges and opportunities for drug monitoring with a view to public health and public safety.

Abstract:
Substance use is a global issue that negatively impacts millions of persons who use drugs (PWUDs). In practice, identifying vulnerable PWUDs for efficient allocation of appropriate resources is challenging due to their complex use patterns (e.g., their tendency to change usage within months) and the high acquisition costs for collecting PWUD-focused substance use data. Thus, there has been a paucity of machine learning models for accurately predicting short-term substance use behaviors of PWUDs. In this paper, using longitudinal survey data of 258 PWUDs in the U.S. Great Plains collected by our team, we design a novel GAN that deals with high-dimensional low-sample-size tabular data and survey skip logic to augment existing data to improve classification models' prediction on (A) whether the PWUDs would increase usage and (B) at which ordinal frequency they would use a particular drug within the next 12 months. Our evaluation results show that, when trained on augmented data from our proposed GAN, the classification models improve their predictive performance (AUROC) by up to 13.4% in Problem (A) and 15.8% in Problem (B) for usage of marijuana, meth, amphetamines, and cocaine, which outperform state-of-the-art generative models.
