Emerging trends in market dynamics and the use of new psychoactive substances are both a public health concern and a complex regulatory issue. One novel area of investigation is the availability of homemade opioids, amphetamines and dissociatives, and the potential fueling of interest in clandestine home manufacture of drugs via the Internet. We illustrate here how online communal folk pharmacology of homemade drugs on drug website forums may actually inform home manufacture practices or contribute to the reduction of harms associated with this practice...

Substance use disorders (i.e., drug addiction) constitute a global and insidious public health issue. Preclinical biomedical research has been invaluable in elucidating the environmental, biological, and pharmacological determinants of drug abuse and in the process of developing innovative pharmacological and behavioral treatment strategies. For more than 70 years, nonhuman primates have been utilized as research subjects in biomedical research related to drug addiction. There are already several excellent published reviews highlighting species differences in both pharmacodynamics and pharmacokinetics between rodents and nonhuman primates in preclinical substance abuse research...

Previous research has implicated the positive modulation of anandamide, an endocannabinoid neurotransmitter, on feeding behavior. Anandamide is particularly noteworthy as it acts as an endogenous ligand of the CB1 receptor, the same receptor that is activated by tetrahydrocannabinol, the primary psychoactive component in Cannabis sativa. Cannabis legalization in North America has presented with a need to study endocannabinoid agonists and their effects on behavior. Much has yet to be determined in terms of the role of the endocannabinoid system in decision-making scenarios...

Ritva Karinen, Gudrun Høiseth
Interpretation of blood concentrations of new psychoactive substances (NPS) requires comparison of the results to previously published case reports; as only a few experimental studies for these substances exist. A large number of articles representing single or multiple cases have been published for a great number of substances, making a unified overview difficult. In this review we have collected all published blood concentrations from the NPS groups classified as phenethylamines, aminoindanes, arylalkylamines, arylcyclohexylamines, and indolalkylamines, and also included unpublished results for MPA, MXE, 4-FMA, 4-FA and 4-MA analyzed in our laboratory...

Autophagy has an essential role in neuronal homeostasis and its dysregulation has been recently linked to neurotoxic effects of a growing list of psychoactive drugs, including amphetamines. However, the role of autophagy in β-keto amphetamine (β-KA) designer drugs-induced neurotoxicity has hitherto not been investigated. In the present study, we show that two commonly abused cathinone derivatives, 3,4-methylenedioxymethcathinone (methylone) and 3,4-methylenedioxypyrovalerone (MDPV), elicit morphological changes consistent with autophagy and neurodegeneration, including formation of autophagic vacuoles and neurite retraction in dopaminergic SH-SY5Y cells...

BACKGROUND: Tobacco and marijuana smoking are very popular in adolescence and there is a high rate of comorbidity between them, even in young adulthood. Parental support and control may hinder involvement in the use of these substances by promoting conventional values among adolescents. OBJECTIVES: The present study investigates the relations between family functioning (parental support and control) and psychoactive substance use (tobacco and marijuana smoking) and determines whether these relationships are mediated by personal values (in terms of disapproval of deviance and beliefs about the importance of school, health and religion)...

Uncertainty exists whether the use of non-prescription psychoactive substances following onset of a first episode of psychosis (FEP), in particular cannabis use, affects medication adherence. Data from FEP patients (N=233) obtained through prospective assessments measured medication adherence and pattern of cannabis and other substance use in the first two years following onset of psychosis. Multiple logistic regression analyses were employed to compare the different substance use groups with regard to risk of medication non-adherence, while controlling for confounders...

OBJECTIVE: To examine the purchasing and supply patterns of new psychoactive substance (NPS) consumers in Australia. METHOD: Data were obtained from a self-selected sample of 296 past-year NPS consumers, with comparisons made across dimethyltryptamine (n = 104), 2C-x (n = 59), NBOMe (n = 27), and synthetic cannabinoid (n = 22) users. RESULTS: Most consumers (58%) nominated a friend as their main NPS source, and almost half (46%) reported that they had supplied NPS to others in the past year (predominantly "social supply")...

New psychoactive substances (NPS) are commonly referred to as "research chemicals", "designer drugs" or "legal highs." One NPS class is represented by dissociative anesthetics, which include analogues of the arylcyclohexylamine phencyclidine (PCP), ketamine, and diphenidine. A recent addition to the NPS market was 4-[1-(3-methoxyphenyl)cyclohexyl]morpholine (3-MeO-PCMo), a morpholine analogue of 3-MeO-PCP. Although suspected to have dissociative effects in users, information about its pharmacological profile is not available...

This chapter reviews what is known about the therapeutic uses of the serotonergic or classic hallucinogens, i.e., psychoactive drugs such as LSD and psilocybin that exert their effects primarily through agonist activity at serotonin 2A (5HT2A) receptors. Following a review of the history of human use and scientific study of these drugs, the data from clinical research are summarized, including extensive work on the use of classic hallucinogens in the treatment of alcoholism and other addictions, studies of the use of LSD and psilocybin to relieve distress concerning death, particularly in patients with advanced or terminal cancer, and more limited data concerning the use of classic hallucinogens to treat mood and anxiety disorders...

The phenomenon of stupefying by the use of available over-the-counter drugs (OTC) among adolescents is an essential problem in both Poland and throughout the world. Popular analgesics, cold medicine and antihistamines contain psychedelic substances, such as dextromethorphan (DXM), pseudoephedrine/ephedrine, codeine (methylmorphine), dimenhydrinate, paracetamol (acetaminophren) and others. Cases of fatal addiction to dextromethorphan, one of the active substances contained in medicines, e.g., the common cold, have been reported...

The prevalence and use of new psychoactive substances (NPS) is increasing and currently over 600 NPS exist. Many illicit drugs and NPS increase brain monoamine levels by inhibition and/or reversal of monoamine reuptake transporters (DAT, NET and SERT). This is often investigated using labor-intensive, radiometric endpoint measurements. We investigated the applicability of a novel and innovative assay that is based on a fluorescent monoamine mimicking substrate. DAT, NET or SERT-expressing human embryonic kidney (HEK293) cells were exposed to common drugs (cocaine, dl-amphetamine or MDMA), NPS (4-fluoroamphetamine, PMMA, α-PVP, 5-APB, 2C-B, 25B-NBOMe, 25I-NBOMe or methoxetamine) or the antidepressant fluoxetine...

BACKGROUND: Cannabis use disorders (CUD) are common in schizophrenia (~25%) compared to the general population (~3%). Tetrahydrocannabinol (THC), the principal psychoactive component in cannabis is fat-soluble, resulting in an extended period for cannabinoid elimination. While detection of cannabinoids in urine is indicative of prior cannabis exposure, time of last use is difficult to verify sustained abstinence for extended periods (e.g., 28-days) in chronic cannabis users. Therefore, we evaluated the utility of a sustained cannabis abstinence paradigm in patients with schizophrenia and non-psychiatric controls...

In the present study, we explored the prevalence of new psychoactive substance use by people admitted into an Australian acute public mental health facility specializing in comorbid mental health and substance use. These substances have since been banned from retail outlets, but the pattern of uptake and reasons people use them is informative in terms of motivations and the management of substance use more generally. A cross-sectional study to explore the use of synthetic cannabis by people admitted to an acute adult mental health unit was undertaken...

INTRODUCTION AND AIMS: In France, the law states that any person held in custody could be examined by a doctor. The main objective of the medical examination is to give medical evidence of health compatibility with custody. This review identifies health risks such as addictive behaviour. We wanted to know which psychoactive substances are used in this particular population, and how problematic these uses are. DESIGN AND METHODS: A prospective, monocentric, open-ended study conducted via a structured questionnaire was carried out on detainees who reported having taken drugs or illegal substances...

ISSUES: Elucidating the role of empathic processes in developmental pathways to substance use disorders could have important implications for prevention. APPROACH: We searched the biomedical and social sciences literature to determine what is known about empathy and psychopathological manifestations of severe lack of empathy in the initiation, development and maintenance of psychoactive substance use. Thirty-seven empirical studies were identified and formally reviewed...
