A large number of emerging contaminants (ECs) are known to persist in surface waters, and create pressure on wastewater treatment works (WWTW) for their effective removal. Although a large database for the levels of these pollutants in water systems exist globally, there is still a lack in the correlation of the levels of these pollutants with possible long-term adverse health effects in wildlife and humans, such as endocrine disruption. The current study detected a total of 55 ECs in WWTW influent surface water, 41 ECs in effluent, and 40 ECs in environmental waters located upstream and downstream of the plant...

OBJECTIVES: While a high rate of recreational drug use (RDU) has been documented among HIV-infected out-patients, particularly in men who have sex with men (MSM), there is a distinct lack of data for HIV-infected in-patients. Hospital admission offers a unique opportunity to engage drug users. We aimed to establish and characterize RDU among new admissions to a large dedicated London HIV in-patient unit and compare it to RDU among general medical admissions to inform clinical pathways...

INTRODUCTION: Mexedrone, 3-methoxy-2-(methylamino)-1-(4-methylphenyl)propan-1-one, is the alpha-methoxy-derivative of mephedrone (4-methyl-N-methyl cathinone). Mexedrone inhibits the re-uptake of serotonin and dopamine in a dose-dependent manner and has affinity for serotonin and dopamine membrane transporters and receptors (5-HT2 and D2 receptors), producing sympathomimetic effects similar to amfetamines. To date there are no published clinical reports on mexedrone use that are analytically confirmed...

BACKGROUND: Abuse of more than one psychoactive drug is becoming a global problem. Our experiments were designed to examine the effects of a concomitant administration of 3,4-methylenedioxy-methamphetamine (MDMA) and mephedrone on depression- and anxiety-like behaviors and cognitive processes in Swiss mice. METHODS: In order to investigate the drug interactions the forced swimming test (FST) - an animal model of depression, the passive avoidance (PA) test - a memory and learning paradigm, as well as the elevated plus maze (EPM) test - test for anxiety level were used...

3-MeO-PCP or 3-methoxyphencyclidine is a derivative of phencyclidine. It acts as a dissociative anesthetic and it has allegedly hallucinogenic and sedative effects. There are almost no documented intoxication cases and references about its pharmacology and toxicity in literature. This study presents two concomitant intoxication cases due to consumption of 3-MeO-PCP and alcohol. A 19 (A) and a 21 years old (B) men were brought to Santa Maria Nuova Hospital in a comatose state (Glasgow score 3). They showed respiratory acidosis, right anisocoria with mydriatic pupils and hypothermia...

Mephedrone (MEPH) is a β-ketoamphetamine stimulant drug of abuse that is often a constituent of illicit bath salts formulations. While MEPH bears remarkable similarities to methamphetamine (METH) in terms of chemical structure, as well as its neurochemical and behavioral effects, it has been shown to have a reduced neurotoxic profile compared to METH. The addition of a β-keto moiety and a 4-methyl ring substituent to METH yields MEPH, and a loss of direct neurotoxic potential. In the present study, 2 analogs of METH, methcathinone (MeCa) and 4-methylmethamphetamine (4MM), were assessed for their effects on mouse dopamine (DA) nerve endings to determine the relative contribution of each individual moiety to the loss of direct neurotoxicity in MEPH...

4-Methyl-N-methylcathinone (mephedrone) is a popular new psychoactive substance (NPS) that is structurally related to the parent compound cathinone, the β-keto analogue of amphetamine. Mephedrone appeared on the street drug market as a substitute for 3,4-methylenedioxy-N-methylamphetamine (MDMA, ecstasy) and was subsequently banned due to the potential health risks associated with its use. Nevertheless, mephedrone continues to be widely consumed among specific populations, with unique patterns of misuse. To date, most information about the biological effects of mephedrone comes from user experiences, epidemiological data, clinical cases, toxicological findings, and animal studies, whilst there are very few data regarding its human pharmacodynamics and pharmacokinetics...

To estimate drug consumption more reliably, wastewater-based epidemiology would benefit from a better understanding of drug residue stability during in-sewer transport. We conducted batch experiments with real, fresh wastewater and sewer biofilms. Experimental conditions mimic small to medium-sized gravity sewers with a relevant ratio of biofilm surface area to wastewater volume (33 m(2) m(-3)). The influences of biological, chemical, and physical processes on the transformation of 30 illicit drug and pharmaceutical residues were quantified...

BACKGROUND: Over the past decade, monitoring systems have identified the rapid emergence of new psychoactive substances (NPS). While the use of many NPS is minimal and transitory, little is known about which products have potential for capturing the attention of significant proportions of the drug consuming market. The aim of this study was to explore self-reported experiences of three commonly used NPS classes within the Australian context (synthetic cathinones, hallucinogenic phenethylamines and hallucinogenic tryptamines) relative to traditional illicit drug counterparts...

Synthetic cathinones are new stimulant drugs derived from cathinone that have been sold as "legal highs" worldwide. These compounds can elicit powerful effects such as delusions, hallucinations as well as other potentially dangerous behavior. New analogs with varying effects and potencies are constantly introduced in the market to evade legislation, and they are not detected by routine screening and confirmation methods. Oral fluid is an alternative matrix of increasing interest in forensic toxicology. Its collection is non-invasive and easily supervised, and positive drug findings typically reflect recent drug exposure...

4-Methylethcathinone (4-MEC) and 3,4-methylenedioxypyrovalerone (MDPV) are synthetic cathinones. The objective of this study was to develop a method in order to measure these compounds in hair of a patient. After decontamination, 20mg of hair were grinded and incubated in phosphate buffer pH 5.0 in presence of 100ng of MDMA-d5 used as internal standard. Double basic liquid-liquid extraction was performed. Samples were separated on a 1.9μm Hypersil GOLD PFP column (100×2.1mm) using gradient elution. Compounds were detected by a LCQ TSQ Vantage XP triple-quadrupole mass spectrometer...

Animal models of drug self-administration are currently the gold standard for making predictions regarding the relative likelihood that a recreational drug substance will lead to continued use and addiction. Such models have been found to have high predictive accuracy and discriminative validity for a number of drug classes including ethanol, nicotine, opioids, and psychostimulants such as cocaine and methamphetamine. Members of the entactogen class of psychostimulants (drugs that produce an "open mind state" including feelings of interpersonal closeness, intimacy and empathy) have been less frequently studied in self-administration models...

Mephedrone is a β-ketoamphetamine belonging to the family of synthetic cathinones, an emerging class of designer drugs known for their hallucinogenic and psychostimulant properties as well as for their abuse potential. The aim of this review was to examine the emerging scientific literature on the possible mephedrone-induced neurotoxicity, yet not well defined due to the limited number of experimental studies, mainly carried on animal models. Relevant scientific articles were identified from international literature databases (Medline, Scopus, etc...

Increasing consumption has been observed among young people of new psychoactive substances, including synthetic cathinone derivatives. The most well known of these is mephedrone whose use has been related to acute intoxication and fatality. Several methods able to detect mephedrone have been reported, although to date, none have been applied to human pharmacokinetic studies in a controlled setting. We developed a gas chromatography-mass spectrometry technique for mephedrone quantification in human plasma and urine...

BACKGROUND: Anecdotal evidence suggests that men who have sex with men (MSM) are increasingly combining sex and illicit drugs (an activity referred to as 'chemsex'), in particular GHB/GBL, ketamine, crystal meth, or mephedrone (here called 4-chems). Use of such drugs has been associated with mental health and sexual health harms. We aim to compare patterns of illicit drug use among MSM in 44 European urban centres. METHODS: In 2010, EMIS recruited 174,209 men from 38 countries to an anonymous online questionnaire in 25 languages...

New psychoactive substances are conquering the drug scene. Among these substances, cathinone derivatives have been observed since late in the year 2000. At that time, an increasing use of the synthetic cathinone mephedrone (4-methylmethcathinone) started to be observed, particularly among night clubbers. Although these new psychoactive drugs showed an appearance of safety, a growing amount of experiences on their secondary effects has been reported. Mephedrone for example is known to induce psychosis. Given the potential negative effects of mephedrone, the laboratory was asked to test for the drug in hair, a cumulative matrix that can document single, occasional or repetitive abuse of xenobiotics...
