Poor inhibitory control and sensitivity to drug reward are two significant risk factors for drug abuse. Although the two have been largely viewed as separate and independent risk factors, there is new evidence to suggest that they may be related at both the behavioral and neural level. This study examined associations between behavioral and neural correlates of inhibitory control and sensitivity to the subjective rewarding effects of amphetamine in humans. Healthy volunteers (n=63) first completed the stop signal task, a behavioral measure of inhibitory control...

UR-144 [(1-pentyl-1H-indol-3-yl)(2,2,3,3-tetramethylcyclopropyl)methanone] is a synthetic cannabinoid, which has been detected in many 'legal highs', seized from the global drug market since the beginning of 2012. It has gained popularity as a 'legal' alternative to classic cannabis in countries where it was not controlled. Despite the widespread distribution of this substance, the data on its effects on the human body are scarce. Therefore, this paper describes the results of analysis and observed effects in 39 cases in which UR-144 was determined in blood...

Electronic cigarette (ECIG) use is growing in popularity, but little is known about the perceived positive outcomes of ECIG use. This study used concept mapping (CM) to examine positive ECIG outcome expectancies. Sixty-three past 30-day ECIG users (38.1% female) between the ages of 18 and 64 (M = 37.8, SD = 13.3) completed a CM module. In an online program, participants provided statements that completed a prompt: "A specific positive, enjoyable, or exciting effect (i.e., physical or psychological) that I have experienced WHILE USING or IMMEDIATELY AFTER USING an electronic cigarette/electronic vaping device is...

BACKGROUND: Tropicamide is a mydriatic drug used as eye-drops for diagnostic or therapeutic purposes. From 2013, a diverted use by intravenous route has been suspected in Eastern Europe in opioids users. To recent date, no signal of a misuse has been identified in France. PURPOSE: To investigate an early signal of a diverted use of tropicamide eye drops and to collect information regarding motives of misusing and tropicamide-induced effects. METHODS: Information was obtained at 1/ regional level (Midi-Pyrénées area): reimbursement data and pharmacists' reports on suspicious requests, 2/ national level: reimbursement data and prescriptions suggesting possible abuse from the OSIAP (Ordonnances Suspectes, Indicateur d'Abus Possible) survey and 3/ international level: VigiBase® reports and Web sources...

Erectile function (EF) is a prerequisite for satisfactory sexual intercourse (SI) and central to male sexual functioning. Satisfactory SI eventually leads to orgasm - a biopsychophysiological state of euphoria - leading to a sense of bliss, enjoyment and positive mental well being. For a psychiatrist, treating ED is self-propelled to harmonize these pleasurable experiences alongside with encouragement of physical wellness and sensuality. Hence, the role of PDE-5i is pivotal in the context of treating ED constitutes a therapeutic challenge...

Cannabis sativa, or marijuana, a popular recreational drug, alters sensory perception and exerts a range of potential medicinal benefits. The present study demonstrates that the endogenous cannabinoid receptor agonists 2-arachidonoylglycerol (2-AG) and anandamide (AEA) activate a canonical cannabinoid receptor in Caenorhabditis elegans and also modulate monoaminergic signaling at multiple levels. 2-AG or AEA inhibit nociception and feeding through a pathway requiring the cannabinoid-like receptor NPR-19. 2-AG or AEA activate NPR-19 directly and cannabinoid-dependent inhibition can be rescued in npr-19-null animals by the expression of a human cannabinoid receptor, CB1, highlighting the orthology of the receptors...

RATIONALE: Alcohol subjective experiences are multi-dimensional and demonstrate wide inter-individual variability. Recent efforts have sought to establish a clearer understanding of subjective alcohol responses by identifying core constructs derived from multiple measurement instruments. OBJECTIVE: The aim of this study was to evaluate the temporal stability of this approach to conceptualizing alcohol subjective experiences across successive alcohol administrations in the same individuals...

γ-Hydroxybutyric acid (GHB), a minor metabolite of the inhibitory neurotransmitter GABA, can accumulate to significant concentrations in the heritable disorder of GABA degradation, succinic semialdehyde dehydrogenase (SSADH) deficiency (SSADHD). Moreover, GHB may be employed in therapeutic settings (treatment of narcolepsy), as well as instances of illicit activity, including acquaintance sexual assault and the induction of euphoria. High-affinity binding sites for GHB in the brain have been identified, although the absolute identity of these receptors remains unclear...

Because of the growing healthcare market and the increasing health consciousness of the population, more and more food supplements are being placed on the market in addition to medicinal products. Concerning the demarcation of medicinal products to food supplements, not only is the intended purpose of the product critical, but the mode of action of the respective preparation also plays an important role. Following the legal definition, a drug has a pharmacological effect, without it being further defined...

BACKGROUND: Behavioral and psychological symptoms of dementia (BPSD) are a group of psychological reactions, psychiatric symptoms, and behaviors commonly found in Alzheimer's disease (AD). Four clusters of BPSD have been described: mood disorders (depression, anxiety, and apathy), psychotic symptoms (delusions and hallucinations), aberrant motor behaviors (pacing, wandering, and other purposeless behaviors), and inappropriate behaviors (agitation, disinhibition, and euphoria). Most of them are attributed to acetylcholine deficiency...

Ecstasy (MDMA; 3,4-methylenedioxymethylamphetamine) is an illicit drug that has been increasingly abused by young people. Its effects include euphoria, enhanced sociability and heightened mental awareness. These come about via the increase of serotonin in both the central nervous system and the sympathetic nervous system. Despite the drug's prevalent abuse, serious or adverse effects are rare. Due to personal pharmacokinetics, effects from the same dosage vary according to the individual. Fatal instances may include acute hyponatremia, hyperthermia (>42 °C), disseminated intravascular coagulation (DIC) resulting from hyperthermia affecting the kidneys, and non-traumatic rhabdomyolysis...

Agonists targeting the kappa opioid receptor (KOR) have been promising therapeutic candidates because of their efficacy for treating intractable itch and relieving pain. Unlike typical opioid narcotics, KOR agonists do not produce euphoria or lead to respiratory suppression or overdose. However, they do produce dysphoria and sedation, side effects that have precluded their clinical development as therapeutics. KOR signaling can be fine-tuned to preferentially activate certain pathways over others, such that agonists can bias signaling so that the receptor signals through G proteins rather than other effectors such as βarrestin2...

BACKGROUND: Conventional laparoscopy (CL) using 3-5 mm ports has become the goldstandard for pediatric nephrectomy (N), heminephrectomy (HN) and heminephrecto-ureterectomy (HNU) for many years now. Recently the spectrum of minimal invasive surgery (MIS) has been extended by variants like laparoendoscopic single-site surgery (LESS) or robot-assisted surgery (RAS). However such technical developments tend to drive surgical euphoria and feasibility studies, but may miss adequate academic research about function and proven patients' benefits...

Loperamide is an over-the-counter antidiarrheal with opioid-receptor agonist properties. Recommended over-the-counter doses (range = 2-8 mg daily) do not produce opioid effects in the central nervous system because of poor oral bioavailability and P-glycoprotein efflux* of the medication (1); recent reports suggest that large doses (50-300 mg) of loperamide produce euphoria, central nervous system depression, and cardiotoxicity (2-4). Abuse of loperamide for its euphoric effect or for self-treatment of opioid withdrawal is increasing (5)...

OBJECTIVES: Since 2001, U.S. military personnel and active duty, uniformed physicians providing medical support have been deployed to Afghanistan. Medical toxicologists are among the physicians deployed. There is a paucity of information present in the literature that has documented cases treated by toxicologists in theater. This prospective observational study describes 15 male patients treated in theater by a military medical toxicologist. METHODS: We performed a prospective observational study in which a medical toxicologist consulted and reported on deployed toxicology cases occurring during a 5-month deployment to Bagram, Afghanistan...

High-level cognitive and emotional experience arises from brain activity, but the specific brain substrates for religious and spiritual euphoria remain unclear. We demonstrate using functional magnetic resonance imaging scans in 19 devout Mormons that a recognizable feeling central to their devotional practice was reproducibly associated with activation in nucleus accumbens, ventromedial prefrontal cortex, and frontal attentional regions. Nucleus accumbens activation preceded peak spiritual feelings by 1-3 s and was replicated in four separate tasks...

In the last few years robotic surgery has progressed from being confined to a small niche to a widespread application in routine visceral surgery; however, evidence for superiority of robotic surgery compared to laparoscopy from randomized studies with a sufficient number of patients is still lacking in most fields of visceral surgery. For complex operations that necessitate an extensive reconstruction phase, such as pancreatectomy, gastrectomy and esophagectomy, there is a potential benefit for the permanent and justified use of robotic surgery...

Cannabis is the illicit substance most widely used by adolescents. Certain personality traits such as impulsivity and sensation seeking, and the subjective effects experienced after substance use (e.g. euphoria or relaxation) have been identified as some of the main etiological factors of consumption. This study aims to categorize a sample of adolescent cannabis users based on their most dominant personality traits (internalizing and externalizing profile). Then, to make a comparison of both profiles considering a set of variables related to consumption, clinical severity and subjective effects experienced...
