Objective: Impairments involving inhibitory control have been considered central deficits in drug users, but it appears that dysfunctions may be specific to users' drug of choice. This article aims to review recent findings on inhibitory control impairment in samples of crack and/or cocaine users. Methods: Searches were conducted on the PubMed, PsycINFO, and Web of Knowledge databases in two stages according to eligibility criteria. Initially, databases were searched and the titles and abstracts of results were analyzed and then selected articles were read in full...

Marijuana is the most commonly used recreational drug in the United States, and legal recreational and medicinal use has gained public acceptance during the last decade. Twenty-nine US states have established medical marijuana programs, 8 of which have also legalized recreational marijuana, and Canada is expected to legalize recreational marijuana in 2018. Advanced chronic kidney disease (CKD) and end-stage renal disease (ESRD) are chronic conditions with significant associated morbidity and mortality. Patients experience substantial symptom burden that is frequently undertreated due to adverse medication side effects...

Novel synthetic opioids (NSO) are increasingly encountered in illicit heroin and counterfeit pain pills. Many NSO are resurrected from older biomedical literature or patent applications, so limited information is available about their biological effects. Here we examined the pharmacology of three structurally-distinct NSO found in the recreational drug market: N-(1-(2-phenylethyl)-4-piperidinyl)-N-phenylbutyramide (butyrylfentanyl), 3,4-dichloro-N-[(1R,2R)-2-(dimethylamino)cyclohexyl]-N-methylbenzamide (U-47700) and 1-cyclohexyl-4-(1,2-diphenylethyl)piperazine (MT-45)...

MDMA/Ecstasy has had a resurgence in popularity, with recent supplies comprising higher strength MDMA, potentially leading to increased drug-related harm. Neurocognitive problems have been widely reported in ecstasy users, equally some studies report null findings, and it remains unclear which factors underlie the development of neurocognitive impairments. This review covers the empirical research into brain activity during neurocognitive performance, using fMRI, fNIRS, and EEG. Our main conclusion is that chronic repeated use of recreational ecstasy can result in haemodynamic and electrophysiological changes that reflect recruitment of additional resources to perform cognitive tasks...

BACKGROUND & PURPOSE: Cannabis is a recreational drug leading to intoxication, due to cannabinoid receptor one (CB1 ) stimulation. However, more recently herbs mixed with synthetic cannabinoids sometimes known as "Spice" and "Black Mamba" have been increasing used and their high CB1 receptor affinity means not only marked intoxication, but life-threatening complications and an increasing number of deaths. Whilst many studies have indicated that prophylactic CB1 receptor antagonism can block cannabimimetic effects in animals and humans...

INTRODUCTION: Human sweat is a complex biofluid of interest to diverse scientific fields. Metabolomics analysis of sweat promises to improve screening, diagnosis and self-monitoring of numerous conditions through new applications and greater personalisation of medical interventions. Before these applications can be fully developed, existing methods for the collection, handling, processing and storage of human sweat need to be revised. This review presents a cross-disciplinary overview of the origins, composition, physical characteristics and functional roles of human sweat, and explores the factors involved in standardising sweat collection for metabolomics analysis...

INTRODUCTION: Despite growing legal control, a wide range of synthetic cannabis analogues is currently used for recreational purposes, notwithstanding their well adverse outcomes, which appear to be more frequent and more serious than those associated with cannabis use. We present the case report of a patient with paranoid schizophrenia, who attempted suicide by serious bodily harm after a single use of "Shiva Ultra Strong," a compound of several synthetic cannabis analogues. CASE SUMMARY: A 32-year-old male patient with paranoid schizophrenia was brought to the emergency department presenting with a severe self-inflicted wound to the neck which lacerated the right jugular vein and ipsilateral airway, and narrowly missed the carotid bifurcation...

The last decade has seen a breakthrough in the treatment of erectile dysfunction (ED) with the advent of phosphodiesterase-5 inhibitors. There are few population-based observational studies on the prevalence of use of these drugs. We conducted a cross-sectional population-based study in the city of Pelotas (Brazil). Our sample comprised 1,082 men aged 20 years or older who answered a confidential and self-administered questionnaire. Prevalence of EDD use was 5% (IC95% = 4%;7%). ED and advanced age were strongly associated with a higher prevalence of EDD use...

IPF is a specific form of chronic fibrosing interstitial pneumonia of unknown cause, characterized by progressive worsening in lung function and an unfavorable prognosis. Current concepts on IPF pathogenesis are based on a dysregulated wound healing response, leading to an over production of extracellular matrix. Based on recent research however, several other mechanisms are now proposed as potential targets for novel therapeutic strategies. Areas covered: This review analyzes the current investigational strategies targeting extracellular matrix deposition, tyrosine-kinase antagonism, immune and autoimmune response, and cell-based therapy...

Habitual drug-seeking behaviour is essential in the transition from recreational drug use to compulsive drug use and is regulated by the dopamine (DA) system of the dorsal striatum (DS). However, a comparative study of the two subtypes of DA receptors, D1 receptors (D1R) and D2 receptors (D2R), which have opposite regulatory functions, in habitual drug-seeking behaviour is absent. Moreover, the effects of L-type calcium channels (LTCCs) and the subtypes Cav1.2 and Cav1.3, which are downstream of D1R and D2R, respectively, on habitual drug-seeking behaviour have yet to be revealed...

Consumption of cannabis and various related products (cannabinoids) for both medicinal and recreational use is gaining popularity. Furthermore, regulatory changes are fostering a cultural shift towards increasing liberalization of cannabis use, thereby increasing the likelihood of even larger numbers of individuals being exposed in the future. The two different types of receptors (CB1 and CB2) that are activated by the pharmacologically active ingredients of cannabis are found in numerous tissues, including the kidneys...

Eight states and the District of Columbia have legalized the recreational use of cannabis for adults and more are expected to follow suit. After alcohol, cannabis is the most commonly used drug by adolescents. Consumption of this drug during this developmental period poses unique risks. Therefore, attention must be paid both to how legalization affects adolescents and how tailored interventions can effectively address their needs for assistance. This commentary offers considerations for how legalization might be crafted so as to benefit adolescents...

3,4-methylenedioxymethamphetamine (MDMA; 'ecstasy') is widely consumed recreationally. Currently little is known about its effects on the human metabolome. Mapping biochemical changes after drug exposure can complement traditional approaches by revealing potential biomarkers of organ toxicity or discovering new metabolomic features in a time- and dose-dependent manner. We aimed to analyze for the first time plasma samples from a randomized, double-blind, placebo-controlled crossover study in healthy adults to explore changes in endogenous plasma metabolites following a single intake of MDMA...

BACKGROUND: Noise-induced hearing loss is a leading cause of occupational and recreational injury and disease, and a major determinant of age-related hearing loss. No therapeutic agent has been approved for the prevention or treatment of this disorder. In animal models, glutathione peroxidase 1 (GPx1) activity is reduced after acute noise exposure. Ebselen, a novel GPx1 mimic, has been shown to reduce both temporary and permanent noise-induced hearing loss in preclinical studies. We assessed the safety and efficacy of ebselen for the prevention of noise-induced hearing loss in young adults in a phase 2 clinical trial...
