BACKGROUND The prevalence of amphetamine-type stimulant use is greater than that of opioids and cocaine combined. Currently, there are no approved pharmacotherapy treatments for amphetamine-type stimulant problems, but some face-to-face psychotherapies are of demonstrated effectiveness. However, most treatment services focus on alcohol or opioid disorders, have limited reach and may not appeal ...

BACKGROUND In recent years, amphetamine-type stimulants (ATS) have increased dramatically in East-south Asia, especially in China. Most ATS users suffered from psychosis comorbidity, and depression is the main syndrome in ATS users. METHODOLOGY A cross-sectional study of depressive symptoms and associated factors among ATS users was conducted in compulsory and voluntary drug detoxification an...

INTRODUCTION HIV risk among female entertainment and sex workers (FESW) remains high and use of amphetamine-type stimulants (ATS) significantly increases this risk. We designed a cluster randomised stepped wedge trial (The Cambodia Integrated HIV and Drug Prevention Implementation (CIPI) study) to test sequentially delivered behavioural interventions targeting ATS use. METHODS AND ANALYSIS Th...

AIMS: There has been a considerable increase in the number of seizures of amphetamine-type stimulant (ATS) tablets in Japan. Characterization and classification of seized ATS tablets can provide very useful information in criminal investigations aimed at identifying drug traffic routes, the sources of supply and relationship between seizures. In the present study, chemical profiling of organic ...

BACKGROUND China, as other Southeast Asian countries, has witnessed an increased use in amphetamine-type stimulants (ATS) amongst urban youth. Amongst female adolescents who both sell sex and use ATS, risk behaviours are compounded resulting in even poorer health outcomes. However, limited knowledge exists on ATS use patterns and ATS-related risk behaviours, particularly in this context. This r...

Amphetamine-type psychostimulants (ATS), such as amphetamine (AMPH), 3,4-methylenedioxymethamphetamine (MDMA), and methamphetamine (METH) are psychoactive substances widely abused, due to their powerful central nervous system (CNS) stimulation ability. Young people particularly use ATS as recreational drugs. Moreover, AMPH is used clinically, particularly for attention deficit hyperactivity dis...

Amphetamine-type stimulants (ATS) are a group of substances, mostly synthetic in origin, that generally stimulate the central nervous system. Chemical modification of their molecular structure results in a practically unlimited number of pharmacologically active compounds, some of which are more potent stimulants than others. The gas chromatography combined with mass spectrometry (GC/MS) and, m...

Use of new amphetamine-type stimulants (ATS) as designer drugs is a serious problem worldwide. ATS are used in tablet, capsule, and powder forms, and can be mixed with other drugs. There is little information available on how these new drugs are metabolized or their ability to inhibit the metabolism of co-administered drugs. This study aimed to investigate the metabolism of six 4-substituted an...
