Acute kidney injury is an important cause of mortality and morbidity today and can occur due to several reasons. As time, geographic regions, and living conditions change, various etiological agents arise with nephrotoxic effects. Awareness of such nephrotoxic effects has been raised with the increasing frequency of addictive substance use, especially among young people in society.

Intermittent alcohol exposure is a common pattern of adolescent alcohol use that can lead to binge drinking episodes. Alcohol use is known to modulate the endocannabinoid system (ECS), which is involved in neuronal communication, neuroplasticity, neuroinflammation and behavior. Adolescent male Wistar rats were exposed to 4-week intermittent alcohol intoxication (3 g/kg injections for 4 days/week) or saline (N = 12 per group). After alcohol deprivation, adult rats were assessed for emotionality and cognition and the gene expression of the ECS and other factors related to behavior and neuroinflammation was examined in the brain...

OBJECTIVE: This review of the scientific literature examines the potential adult sequelae of exposure to cannabis and related synthetic cannabinoids in adolescence. We examine the four neuropsychiatric outcomes that are likely most vulnerable to alteration by early cannabinoid use, as identified within both the clinical and preclinical research: cognition, emotional functioning, risk for psychosis, and addiction. METHOD: A literature search was conducted through PubMed, PsychInfo, and Google Scholar with no publication date restrictions...

A brown powder and different product packages of "spice-like" herbal incenses were analyzed using a systematic identification approach based on liquid chromatography with diode array detector (HPLC-PDA) and gas chromatography mass spectrometry (GC-MS) with computer based library search against spectral libraries. However, the most predominant compound in the methanolic sample solutions could not be identified. In order to elucidate the chemical structure, a more extensive analysis of the material was initiated using liquid chromatography mass spectrometry (LC-MS), electrospray high resolution mass spectrometry (ESI-HRMS) and (1)H, (13)C and (19)F nuclear magnetic resonance spectroscopy (NMR), which allowed the identification and characterization of the major compound as methyl 2-[[1-(5-fluoropentyl)indole-3-carbonyl]amino]-3,3-dimethyl-butanoate (5F-MDMB-PICA)...

Cannabis and synthetic cannabinoids are widely used illicit substances in Turkey. The Cannabis Use Problems Identification Test (CUPIT) is a brief self-report screening instrument for detection of problematic cannabis use, whereas the Cannabis Problems Questionnaire (CPQ) is a measure for cannabis treatment outcome. The aim of this study was to evaluate the psychometric properties of the CUPIT and CPQ among Turkish male outpatients with cannabis (n = 52) and synthetic cannabinoid (n = 45) use disorder. Participants were evaluated with the CUPIT, the CPQ, and the Cannabis Withdrawal Scale (CWS)...

Synthetic cannabinoids are relatively new substances of abuse. Recently, abuse of synthetic cannabinoids has been increasingly reported in the lay press and medical literature. When new compounds are introduced, their use is initially not restricted by prohibition therefore their consumption cannot be verified by standard drug tests. The use of these compounds among adolescents and young adults is constantly growing, making it important for emergency services to be familiar with the signs and symptoms of intoxication present...

BACKGROUND: New psychoactive substances (NPS) have been increasingly consumed by people who use drugs in recent years, which pose a new challenge for treatment services. One of the largest groups of NPS is synthetic cannabinoids (SCs), which are intended as a replacement to cannabis. While there is an increasing body of research on the motivation and the effects associated with SC use, little is known about the subjective interpretation of SC use by the people who use drugs themselves...

3,4-methylenedioxypyrovalerone (MDPV) is a synthetic cathinone belonging to the class of α-pyrrolidinophenones that become increasingly popular as a designer psychostimulant. Here, we report a comprehensive collection of MDPV exposure with quantitative serum level confirmation in Germany. During the years 2014-2016, we could proof consumption of MDPV in 23 cases where urine and blood samples were submitted to our laboratory by the police of Lower Saxony. Most of the samples underwent systematic toxicological analysis by gas chromatography-mass spectrometry (GC-MS), where MDPV could be detected in urine and/or serum samples...

In the early 2000s in Europe and shortly thereafter in the USA, it was reported that 'legal' forms of marijuana were being sold under the name K2 and/or Spice. Active ingredients in K2/Spice products were determined to be synthetic cannabinoids (SCBs), producing psychotropic actions via CB1 cannabinoid receptors, similar to those of Δ(9)-tetrahydrocannabinol (Δ(9)-THC), the primary active constituent in marijuana. Often abused by adolescents and military personnel to elude detection in drug tests due to their lack of structural similarity to Δ(9)-THC, SCBs are falsely marketed as safe marijuana substitutes...

PURPOSE: Nabilone is a synthetic cannabinoid with properties that make it an appealing candidate as a postoperative nausea and vomiting (PONV) prophylactic adjunct. Nabilone has proven clinical utility in chemotherapy-related nausea and vomiting but has not been adequately tested for PONV. The purpose of this study was to evaluate the effectiveness of a single dose of nabilone for the prevention of PONV. METHODS: This was a pragmatic single-centre randomized-controlled trial comparing oral nabilone vs placebo for the prevention of PONV...

BACKGROUND AND AIMS: There is a growing use of novel psychoactive substances (NPSs) including synthetic cannabinoids. Synthetic cannabinoid products have effects similar to those of natural cannabis but the new synthetic cannabinoids are more potent and dangerous and their use has resulted in various adverse effects. The purpose of the study was to assess whether persistent use of synthetic cannabinoids is associating with impairments of executive function in chronic users. METHODS: A total of 38 synthetic cannabinoids users, 43 recreational cannabis users, and 41 non-user subjects were studied in two centers in Hungary and Israel...

The Cannabinoid Receptor 2 (CB2R) is a G protein-coupled receptor (GPCR) investigated intensively as therapeutic target, however no drug has reached the market yet. We investigated personal differences in CB2R drug responses using a label-free whole-cell assay (xCELLigence) combined with cell lines (Lymphoblastoid Cell Lines) from individuals with varying CB2R genotypes. Responses to agonists, partial agonists and antagonists of various chemical classes were characterized. Endogenous cannabinoids such as 2-AG induced cellular effects vastly different from all synthetic cannabinoids, especially in their time-profile...

BACKGROUND: Increasing reports of synthetic cannabinoid (SC)-related adverse events have largely comprised case reports and analyses of calls to poison control centers. Existing studies have also mostly involved white male populations. OBJECTIVES: The purpose of this study is to systematically describe clinical characteristics of SC use in a relatively large, diverse, urban sample presenting to a psychiatric emergency setting. METHODS: SC users (n = 110) were identified by reviewing charts (n = 948) from the psychiatric emergency service of a large, urban public hospital in the United States for November 2014, which was randomly selected from the 12 months of that year...

BACKGROUND: Women report greater sensitivity to the subjective effects of Δ(9)-tetrahydrocannabinol (THC). Similarly, female rodents tend to be more sensitive to some pharmacological effects of THC and synthetic cannabinoids. This study examined sex differences in discriminative stimulus and response rate effects of THC and synthetic cannabinoids in rats. METHODS: A cumulative dosing THC discrimination procedure was utilized to evaluate sex differences in the discriminative stimulus effects of THC and three synthetic cannabinoids: CP47,497, WIN55,212-2, and JWH-018...
