Molly has been the street name for powder or crystalline ecstasy (3,4-methylenedioxymethamphetamine [MDMA[) in the United States since at least 2008; however, few studies have examined Molly use or included Molly in the definition of ecstasy/MDMA. Prevalence of self-reported ecstasy use is being underreported on surveys due to the lack of inclusion of "Molly", although Molly is often so adulterated with novel psychoactive substances such as synthetic cathinones ("bath salts") that the name "Molly" may no longer adequately represent ecstasy/MDMA...

Substance addiction in young adults is particularly problematic. Yet, much remain at stake in understanding the specifics of this population's access to services. The objective of this study is to explore young adults' initiation of substance misuse treatment. Our study sample was composed of 35 individuals aged 18 to 30 with problematic psychoactive substance use who have been identified in criminal courts, hospital emergency departments, and Health and Social Services Centers in Québec (Canada). A thematic analysis was performed on the 62 semi-structured interviews conducted with participants...

25B-NBOMe and 25C-NBOMe are potent 5-HT2A receptor agonists that have been associated with inducing hallucinogenic effects in drug users and severe intoxications. This paper describes the identification of their metabolites in rat and human urine by liquid chromatography (LC)-high resolution (HR)-MS/MS, the comparison of metabolite formation in vitro and in vivo and in different species, the general involvement of human cytochrome-P450 (CYP) isoenzymes on their metabolism steps, and their detectability by standard urine screening approaches (SUSAs) using GC-MS, LC-MS(n), or LC-HR-MS/MS...

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...

The nature of the global drugs market has evolved rapidly and has become more complex with the emergence of new psychoactive substances (NPS), some of which have been associated with increased abuse, hospital emergency admissions and sometimes fatalities. NPS are characterized by geographic heterogeneity, with some only transient in nature and others not satisfying the criteria for harm required for international control. Consequently, a pragmatic response of the international community is to prioritize the most harmful, persistent and prevalent substances for action - an objective, which is hampered by the paucity of data on harms...

As the number of new 'psychoactive substances' detected globally has risen exponentially, the policy response of assessing and prohibiting each new substance individually has become increasingly unworkable. In an attempt to disrupt the availability of new as-yet-unscheduled substances, Ireland (2010), Poland (2011), Romania (2012), New Zealand (2013), Australia (2015) and the United Kingdom (2016) have enacted generic or blanket ban legislation that prohibits all 'psychoactive substances' that are not already regulated or belong to exempt categories...

An analytical method using ultra performance liquid chromatography (UPLC) quadrupole time-of-flight mass spectrometry (QTOF-MS) was developed and validated for the targeted toxicological screening and quantification of commonly used pharmaceuticals and drugs of abuse in postmortem blood using 100 µL sample. It screens for more than 185 drugs and metabolites and quantifies more than 90 drugs. The selected compounds include classes of pharmaceuticals and drugs of abuse such as: antidepressants, antipsychotics, analgesics (including narcotic analgesics), anti-inflammatory drugs, benzodiazepines, beta-blockers, amphetamines, new psychoactive substances (NPS), cocaine and metabolites...

BACKGROUND: Novel psychoactive substances (NPS) are new narcotic or psychotropic drugs that are not controlled by the United Nations drug convention that may pose a serious public health threat due to their wide availability for purchase on the internet and in so called "head shops." Yet, the extent of their global use remains largely unknown. The aim of this study is to conduct a systematic review of the prevalence of NPS use in non-clinical populations. METHODS: This is a systematic review of observational studies...

Synthetic cannabinoids are one of most abused new psychoactive substances. The recreational use of abused drug has aroused serious concerns about the consequences of these drugs on infection. However, the effects of synthetic cannabinoid on resistance to tetanus toxin are not fully understood yet. In the present study, we aimed to determine if the administration of synthetic cannabinoids increase the susceptibility to tetanus toxin-induced motor behavioral deficit and functional changes in cerebellar neurons in mice...

Anxiety disorders were long underestimated in children by healthcare professionals, but they are now better diagnosed. They account for the most frequent psychiatric diagnosis between 6 and 18 years of age, with differences in prevalence or risk factors related to the clinical forms. Different clinical subtypes of anxiety disorders are detailed in this article: separation anxiety, specific phobia, generalized anxiety, social anxiety, panic disorder, post-traumatic stress syndrome, and obsessional-compulsive disorder...

Pregabalin has become more widely prescribed and abused in recent years but is still not always included in laboratory analysis. An LC-MS-MS method has been developed and applied to measure pregabalin in 93 postmortem cases, including drug-related deaths, alternative causes of death, and fatalities where pregabalin was likely to have contributed to death. Other drugs or alcohol was detected, and the most common drug types (in decreasing frequency) were antidepressants, opioids, benzodiazepines, opiates, alcohol, antipsychotics, cocaine, cardiac drugs, amphetamines, cannabis, anticonvulsants, and antihistamines...

Background: Synthetic drug use and abuse are on the rise. Governmental institutions report a shift in consumption from natural drugs to synthetic drugs, and show an increase in confiscation, particularly of methamphetamine and newly identified psychoactive substances. In addition, the media report an alarming increase in the rate of consumption and casualties resulting from the use of drugs such as "crystal meth" and warn against a flood of this and other designer drugs from eastern European countries. Objectives: The present article gives an overview of current popular and widely used synthetic drugs, both classical substances (amphetamine, methamphetamine, MDMA) and new psychoactive substances ("designer drugs", "legal highs")...

New Psychoactive Substances (NPS) belong to several chemical classes, including phenethylamines, piperazines, synthetic cathinones and synthetic cannabinoids. Development and validation of analytical methods for the determination of NPS both in traditional and alternative matrices is of crucial importance to study drug metabolism and to associate consumption to clinical outcomes and eventual intoxication symptoms. Among different biological matrices, hair is the one with the widest time window to investigate drug-related history and demonstrate past intake...

BACKGROUND: Evolutionary research on drug abuse has hitherto been restricted to proximate studies, considering aetiology, mechanism, and ontogeny. However, in order to explain the recent emergency of a new behavioral pattern (e.g. 'the e-psychonaut style') of novel psychoactive substances' (NPS) intake, a complementary evolutionary model may be needed. OBJECTIVE: A range of evolutionary interpretations on the 'psychonaut style' and the recent emergency of NPS was here considered...

BACKGROUND: Although empirical studies have reported on substance use in children in India, multivariable statistical models examining risk factors in children seeking treatment for substance use are largely lacking. The goal of this study was to test a conceptual model predicting age of first use, duration of use of any psychoactive substance, and primary substance of choice from child and family characteristics in a sample of children entering substance use treatment. METHODS: This was a single-sample cross-sectional study of 159 children entering a treatment and rehabilitation center in Delhi that provides substance use treatment and teaches children the skills to allow for their re-integration into society...

Metabolite profiling of novel psychoactive substances (NPS) is critical for documenting drug consumption. N-(1-amino-3,3-dimethyl-1-oxobutan-2-yl)-1-(4-fluorobenzyl)-1H-indazole-3-carboxamide (ADB-FUBINACA) is an emerging synthetic cannabinoid whose toxicological and metabolic data are currently unavailable. We aimed to determine optimal markers for identifying ADB-FUBINACA intake. Metabolic stability was evaluated with human liver microsome incubations. Metabolites were identified after 1 and 3 h incubation with pooled human hepatocytes, liquid chromatography- high resolution mass spectrometry in positive-ion mode (5600+ TripleTOF®, Sciex) and several data mining approaches (MetabolitePilot™, Sciex)...

BACKGROUND: Hard core smokers have been studied in many countries but only a few trials have compared the effectiveness of smoking cessation with other smokers. The objective of this study was to compare the frequencies of success in smoking cessation between hard-core smokers and other smokers. METHODS: Data were collected in Clermont-Ferrand from the Emile Roux dispensary 'Pneumology and Tobaccology Centre' between 1999 and 2009. Assistance with smoking cessation was proposed to 1367 patients but only 1296 patients were included: 219 HCS and 1077 other smokers...

BACKGROUND: A new trend among users of new psychoactive substances' the consumption of "herbal highs": plant parts containing psychoactive substances. Most of the substances extracted from herbs, in old centuries were at the centre of religious ceremonies of ancient civilizations. Currently, these herbal products are mainly sold by internet web sites and easily obtained since some of them have no legal restriction. OBJECTIVE: We reviewed psychoactive effects and neuropharmacology of the most used "herbal highs" with characterized active principles, with studies reporting mechanisms of action, pharmacological and subjective effects, eventual secondary effects including intoxications and/or fatalities Method: The PubMed database was searched using the following key...
