n-Ethyl pentylone (NEP) is a chemical substance derived from cathinone. Synthetic cathinones are an evolving group of drugs with stimulating, mind-altering effects sometimes referred to as novel or new psychoactive substances (NPS). There is scarce information in the medical literature regarding forensic cases in which NEP is detected in toxicological testing. We present four fatalities involving NEP from Alabama in 2017. Deaths were attributed to NEP toxicity in two cases (peripheral blood concentrations of 0...

Novel psychoactive substances (NPS) refer to synthetic compounds or derivatives of more widely known substances of abuse that have emerged over the last two decades. Case reports suggest that users combine substances to achieve desired psychotropic experiences while reducing dysphoria and unpleasant somatic effects. However, the pattern of combining NPS has not been studied on a large scale. Here, we show that posts discussing NPS describe combining nootropics with sedative-hypnotics and stimulants with plant hallucinogens or psychiatric medications...

INTRODUCTION: Voters in eight U.S. states have passed initiatives to legalize large-scale commercial production of cannabis for non-medical use. All plan or require some form of "seed-to-sale" tracking systems, which provide a view of cannabis market activity at a heretofore unimagined level of detail. Legal markets also create a range of new matters for policy makers to address. DATA: Publicly available data were obtained on approximately 45 million individually priced items purchased in the 35 million retail transactions that took place during the first two and a half years of Washington State's legal cannabis market...

Recently, a range of prescription and over-the-counter drugs have been reportedly used as Novel Psychoactive Substances (NPS), due to their potential for abuse resulting from their high dosage/idiosyncratic methods of self-administration. This paper provides a systematic review of the topic, focusing on a range of medications which have emerged as being used recreationally, either on their own or in combination with NPS. Among gabapentinoids, pregabalin may present with higher addictive liability levels than gabapentin, with pregabalin being mostly identified in the context of opioid, polydrug intake...

Cannabidiol (CBD), the major non-psychoactive constituent of Cannabis sativa, has received attention for therapeutic potential in treating neurologic and psychiatric disorders. Recently, CBD has also been explored for potential in treating drug addiction. Substance use disorders are chronically relapsing conditions and relapse risk persists for multiple reasons including craving induced by drug contexts, susceptibility to stress, elevated anxiety, and impaired impulse control. Here, we evaluated the "anti-relapse" potential of a transdermal CBD preparation in animal models of drug seeking, anxiety and impulsivity...

Childhood physical abuse (PA) and sexual abuse (SA) interact with monoamine oxidase A (MAOA) gene polymorphism to modify risk for mental disorders. In addition, PA and SA may alter gene activity through epigenetic mechanisms such as DNA methylation, thereby further modifying risk for disorders. We investigated whether methylation in a region spanning the MAOA first exon and part of the first intron was associated with PA and/or SA, MAOA genotype, alcohol dependence, drug dependence, depression disorders, anxiety disorders, and conduct disorder...

BACKGROUND: Psychoactive substances are often regarded as causal factors contributing to violent injuries, sexual abuse and homicides. While these effects have been demonstrated for some substances (e.g. cocaine), current available data for others are more controversial (e.g. cannabis) or very limited (e.g. ecstasy). AIMS OF THE STUDY: To collect data on the type and frequency of psychoactive substance use in cases of emergency department (ED) presentations related to interpersonal violence...

Introduction Novel psychotropic substances also known as legal highs are a major concern in UK prisons, fuelling violence and putting a strain on resources for inmates requiring medical treatment for adverse effects. We provide a clinical toxicology service including routine screening for novel psychoactive substances. In 2015, we were approached by Her Majesty Prison Service search dog training team to advise on which novel psychoactive substances to target, and again in 2016 to further provide analytical support to test five letters which the dogs positively identified for novel psychotropic substances during routine searches of prison mail rooms...

INTRODUCTION: Most countries have laws against driving while impaired by drugs. However, in many countries, including Canada and the United States, police must have individualized suspicion that the driver has recently used an impairing substance before they can gather the evidence required for laying a criminal charge. This report studies police documentation of drug involvement among drivers who had a motor-vehicle crash after using an impairing substance. METHODS: We obtained blood samples and police reports on injured drivers treated in participating British Columbia trauma centres following a crash...

Objective: To assess through a systematic review of the literature if the practice of splitting tablets containing psychoactive/psychotropic medications for medical or economic reasons would result in the expected doses. Data Sources: A MEDLINE and PsycInfo comprehensive search of English-language publications from January 1999 to December 2015 was conducted using the terms describing tablet splitting (tablet splitting, split tablets, tablet subdivision, divided tablets, and half tablets) and psychoactive substances (psychoactive medicines, psychotropic medicines, antidepressants, anxiolytics, anticonvulsants, antipsychotics, and antiparkinsonian agents)...

: Novel psychoactive substance use is a major social concern. Their use may elicit or uncover unpredictably as yet undescribed clinical pictures. We aimed to illustrate a multisubstance use case indistinguishable from paranoid schizophrenia, so to alert clinicians on possibly misdiagnosing substance-induced psychotic disorders. CASE REPORT: We describe a case of a 32-year-old man who started at 18 years with cannabinoids and ketamine, and is currently using N-methyl-D-aspartate (NMDA) antagonists...

Pregnancy can be a motivation for decrease in drug abusing but may also represent a period of high vulnerability for relapse. We aimed to assess psychoactive substance use among women with substance use disorders followed in addiction care centers in France. We analyzed data from women aged 15-44 years included in the 'Observation of illegal drugs and misuse of psychotropic medication (OPPIDUM) survey', an annual cross-sectional survey collecting details on psychoactive substances used. Characteristics of women included in 2005-2012 yearly surveys were compared depending on their pregnant or not pregnant status...

BACKGROUND: In veterans, post-traumatic stress disorder (PTSD) is often associated with substance abuse, which in turn can lead to cirrhosis. Cirrhotic patients are prone to cognitive impairment, which is typically due to covert hepatic encephalopathy (CHE), but can also be affected by PTSD. The aim was to define the impact of PTSD on cognitive performance and the diagnosis of CHE in cirrhotic patients. METHODS: Outpatient veterans with cirrhosis underwent two separate modalities for CHE cognitive testing [Psychometric Hepatic Encephalopathy Scale (PHES) and Inhibitory Control Test (ICT)]...

Cannabis (also known as marijuana) is the most frequently used illicit psychoactive substance in the world. Though it was long considered to be a "soft" drug, studies have proven the harmful psychiatric and addictive effects associated with its use. A number of elements are responsible for the increased complications of cannabis use, including the increase in the potency of cannabis and an evolution in the ratio between the two primary components, Δ9 -tetrahydrocannabinol (Δ9 -THC) and cannabidiol (toward a higher proportion of Δ9 -THC), Synthetic cannabinoid (SC) use has rapidly progressed over the last few years, primarily among frequent cannabis users, because SCs provide similar psychoactive effects to cannabis...

REVIEW
Charles R Caffrey, Patrick M Lank
Patients can use numerous drugs that exist outside of existing regulatory statutes in order to get "legal highs." Legal psychoactive substances represent a challenge to the emergency medicine physician due to the sheer number of available agents, their multiple toxidromes and presentations, their escaping traditional methods of analysis, and the reluctance of patients to divulge their use of these agents. This paper endeavors to cover a wide variety of "legal highs," or uncontrolled psychoactive substances that may have abuse potential and may result in serious toxicity...
