The emergence in recent years of potentially dangerous new psychoactive substances (NPS) that are not under international control has led to the development of multi-analyte procedures for their unequivocal quantification. A fast ultra-performance liquid chromatography-tandem mass spectrometry method (UPLC-MS/MS), in combination with a sample pretreatment based on microextraction by packed sorbent (MEPS), was for the first time used in this work for the simultaneous determination of NPS in oral fluid. This matrix is an effective alternative to typical biological samples for drug control in substitution therapy programs, and also for the prevention and reduction of traffic accidents...

N Arnaud, T Thomasius
Methamphetamine (also known as meth and crystal meth) is a highly psychoactive synthetic amphetamine type stimulant, which falls under the German Federal Narcotics Law. The substance is similar to other stimulants but has distinct features with respect to psychoactive effects, clinical symptoms, user characteristics and short and long-term consequences including substance-induced problems and comorbidities. The consumption and misuse of crystal meth is still limited to certain regions in Germany; however, the substance causes significant clinical and public health concerns in the affected regions and beyond due to the associated high potential for misuse and dependence, neurotoxic and neurodegenerative effects as well as many other severe health risks...

BACKGROUND: Prescription opioid (PO) overdose deaths increased sharply over the last decade. Changes in PO deaths in combination with other psychoactive substances may provide a partial explanation. METHODS: PO deaths from the National Multiple-Cause-of-Death Files for 2002-03 (N=15,973) and 2014-15 (N=41,491) were analyzed. We calculated (1) changes in proportions of deaths in combination with benzodiazepines, antidepressants, heroin, alcohol, cocaine between the two periods, and (2) proportions of increase in deaths attributable to each substance among PO and synthetic opioids other than methadone (SO-M) deaths, by age, gender, race/ethnicity...

BACKGROUND: Benzofurans and benzodifurans are two groups of psychoactive substances that had originally been synthesized for research purpose. Benzofurans' structure is quite similar to the known recreational drug 3,4-methylenedioxymethamphetamine together with its active metabolite 3,4-methylenedioxyamphetamine. Benzodifurans are closely related to phenethylamines, but have more hallucinogens effects and much longer duration of action. This study aims to review the accessible evidence-based literature on benzofurans and benzodifurans pharmacology and toxicology...

Jolanta B Zawilska
The abuse of novel psychoactive substances (NPS) has been increasing dramatically worldwide since late 2000s. By the end of 2015, more than 560 NPS had been reported to the European Monitoring Centre for Drugs and Drug Addiction. Although the most popular compounds are synthetic cannabinoids and psychostimulatory derivatives of cathinone (so-called β-keto-amphetamines), novel synthetic opioids have recently emerged on the recreational drug market. They include fentanyl (a potent narcotic analgesic) and its analogs (e...

Until the law in the United Kingdom (UK) changed in May 2016 so called "legal highs" or "new psychoactive substances" were freely available in high street shops across the UK. Following prohibition these drugs are still easily purchased illegally via the internet. We report a case of a patient who self-administered 3-fluorophenmetrazine intravenously with catastrophic consequences. Adverse effects were almost immediate with symptoms of malaise and tachycardia. Two days post administration he was transferred to the intensive therapy unit with acute kidney injury and irreversible four limb ischaemia...

"Krokodil" is the street name for a homemade injectable drug that has been used as a cheap substitute for heroin. Codeine is the opioid starting material for krokodil synthesis and desomorphine is the opioid claimed to be the main component of krokodil and the main responsible for its addictive and psychoactive characteristics. However, due to its peculiar manufacture, using cheap raw materials, krokodil is composed by a large and complex mixture of different substances. In order to shed some light upon the chemical complexity of krokodil, its profiling was conducted by reverse phase high performance liquid chromatography coupled to photodiode array detector (RP-HPLC-DAD) and by liquid chromatography coupled to high resolution tandem mass spectrometry (LC-ESI-IT-Orbitrap-MS)...

Differentiation of new psychoactive substance (NPS), 6-(2-methylaminopropyl)benzofuran (6-MAPB), and its positional isomer, 2-(2-methylaminopropyl)benzofuran (2-MAPB), by means of gas chromatography/mass spectrometry (GC/MS) with quadrupole detection is ambiguous. Reliable distinguishing of the two isomers could be achieved by MS/MS spectra recorded after collision-induced dissociation (CID) of precursor ions. Both electron ionization (EI) and electrospray ionization (ESI) methods could be used for these purposes...

BACKGROUND: It is well known that powdery drugs such as cocaine and heroin are frequently adulterated or diluted predominantly to obtain more doses and to increase the drug dealer's profits, but also to enhance, to modify or to oppose drug effects. METHODS: The aim of this report is to provide an overview of the recent scientific literature on medicines as well as on new psychoactive substances, used as cutting agents (i.e. pharmacologically active adulterants) and on the related adverse health effects on consumers, possibly due to the synergistic effect of the adulterants laced with substances of abuse, which represent a matter of great concern because of the frequent fatalities...

N,N-dimethyltryptamine (DMT) is a psychoactive substance that has been gaining popularity in therapeutic and recreational use. This is a case of a physician who chronically took DMT augmented with phenelzine in an attempt to self-medicate refractory bipolar depression. His presentation of altered mental status, mania, and psychosis is examined in regards to his DMT use. This case discusses DMT, the possible uses of DMT, and the theorized mechanism of DMT in psychosis and treatment of depression, particularly involving its agonist activity at 5-HT1A, 5-HT2A, and 5-HT2C...
