The legalization of marijuana in the USA for both medicinal and recreational use has increased in the past few years. Currently, 24 states have legalized marijuana for medicinal use. The US Drug Enforcement Administration has classified marijuana as a Schedule I substance. The US Food and Drug Administration does not regulate formulations or packages of marijuana that are currently marketed in states that have legalized marijuana. Marijuana edibles or "medibles" are typically packages of candies and baked goods consumed for medicinal as well as recreational marijuana use...

BACKGROUND: Between 2008 and 2013, powder-stimulants sold by 'head shops' as novel psychoactive substances (NPS) or 'legal highs' have displaced heroin among groups of injecting substance users in Bucharest, Romania. Rising HIV-infection rates and other medical or social harms have been reported to follow this trend. METHODS: The study builds on two sets of original (N=30) and existing (N=20) interview data and on observations collected mainly at the site of a methadone substitution treatment facility...

Traffic policies show growing concerns about driving under the influence of cannabis, since cannabinoids are one of the most frequently encountered psychoactive substances in the blood of drivers who are drug-impaired and/or involved in accidents, and in the context of a legalization of medical marijuana and of recreational use. The neurobiological mechanisms underlying the effects of cannabis on safe driving remain poorly understood. In order to better understand its acute and long-term effects on psychomotor functions involved in the short term ability and long-term fitness to drive, experimental research has been conducted based on laboratory, simulator or on-road studies, as well as on structural and functional brain imaging...

BACKGROUND: Schizophrenia is a chronic, relapsing, mental disorder, and lack of adherence is a common and severe problem in such patients leadingto global and heavy consequences for patients (relapses, hospitalizations, impaired quality of life…), for the family and for society. Improved understanding of the underlying reasons will help to form intervention strategies relevant to the context. OBJECTIVES: We aimed to assess medication adherence among stable patients suffering from schizophrenia and to identify factors associated with non-adherence...

The "Adrenaline Instead of Amphetamine" program was launched by Gdańsk's MONAR association-a center for drug treatment. The purpose of the program was to show some alternatives to using psychoactive substances and to propose replacing these anti-medical behaviors with parachuting. The treatment effectiveness in this center is about 30%, and the program's effectiveness was 80%.

BACKGROUND: The high prevalence of comorbid illicit drug use in persons with chronic psychotic illness represents a strong determinant of psychotic relapse and rehospitalization. Epidemiological studies indicate changing patterns of illicit drug use in Australia, which are concerning because of increased use of crystal methamphetamine, also known as "ice." An important complication of habitual use of crystal methamphetamine is the development of a dose-dependent acute psychotic reaction...

Neuroenhancement (NE) is the non-medical use of psychoactive substances to produce a subjective enhancement in psychological functioning and experience. So far empirical investigations of individuals' motivation for NE however have been hampered by the lack of theoretical foundation. This study aimed to apply drug instrumentalization theory to user motivation for NE. We argue that NE should be defined and analyzed from a behavioral perspective rather than in terms of the characteristics of substances used for NE...

STUDY OBJECTIVES: Drugs and psychoactive substances can cause sleepiness and when undetected, may lead to over diagnosis of central hypersomnias. We performed urine drug testing using gas chromatography-mass spectrometry in adults undergoing multiple sleep latency testing (MSLT) for a suspected central hypersomnia. We examined how the drug test results modified the treating physician's diagnosis. METHODS: One hundred eighty-six consecutive patients with a suspected central hypersomnia who underwent clinical assessment, MSLT and urine drug testing by gas chromatography-mass spectrometry were retrospectively studied...

Designer benzodiazepines represent an emerging class of new psychoactive substances (NPS). While other classes of NPS such as cannabinoid receptor agonists and designer stimulants are mainly consumed for hedonistic reasons, designer benzodiazepines may also be consumed as 'self-medication' by persons with anxiety or other psychiatric disorders or as stand-by 'antidote' by users of stimulant and hallucinogenic drugs. In the present study, five benzodiazepines (adinazolam, cloniprazepam, fonazepam, 3-hydroxyphenazepam, and nitrazolam) and one thienodiazepine (metizolam) offered as 'research chemicals' on the Internet were characterized and their main in vitro phase I metabolites tentatively identified after incubation with pooled human liver microsomes...

Cannabinoids are still classified as illegal psychoactive drugs despite their broad and increasingly acknowledged therapeutic potential. These substances are most famous for their wide recreational use, particularly among young adults to either alter the state of consciousness, intensify pleasure induced by other psychoactive substances or as an alternative to the previously abused drugs. It is important to emphasize that cannabinoids are often taken together with a variety of medications intended for the treatment of alcohol use disorder (AUD) or alcohol withdrawal syndrome (AWS)...

INTRODUCTION: Synthetic Cannabinoid Receptor Agonists (SCRAs) are the largest group of new psychoactive substances reported to the European Warning System and the United Nations Office on Drugs and Crime to date. The heterogeneous nature and speed of diversification of these compounds make it challenging to accurately characterise and predict harms of these compounds in pre-clinical studies, ahead of their appearance. CASE REPORT: We report the case of a 19-year-old female who purchased three products from a headshop: two new psychoactive substances (sachets of "cannabis tea" and "mushroom tea") as well as two LSD blotters...

As medical and recreational use of cannabis, or marijuana, becomes more prevalent, law enforcement needs a tool to evaluate whether drivers are operating vehicles under the influence of cannabis, specifically the psychoactive substance, tetrahydrocannabinol (THC). However, the cutoff concentration of THC that causes impairment is still controversial, and current on-site screening tools are not sensitive enough to detect trace amounts of THC in oral fluids. Here we present a novel sensing platform that employs giant magnetoresistive (GMR) biosensors integrated with a portable reader system and smartphone to detect THC in saliva using competitive assays...

Novel psychoactive substances (NPS) are easily accessible and the consumption has increased in recent years. New compounds as well as compounds derived from pharmaceutical research or the patent literature are provided, mostly without any declaration. As a consequence, severe adverse reactions may occur after consumption of unknown doses of these drugs, in particular after mixed intake of different psychoactive substances or co-medication. The toxic effects in such cases are not predictable. We report cases of rhabdomyolysis in patients after consumption of desoxipipradrol in combination with other NPS...

REVIEW
June Bryan de la Peña, Jae Hoon Cheong
The tiletamine-zolazepam (TZ) combination is an anaesthetic drug commonly used in veterinary medicine. It is an equal amount combination of tiletamine, a dissociative anaesthetic pharmacologically classified as an N-methyl-D-aspartate (NMDA) receptor antagonist, and zolazepam, a benzodiazepine tranquilizer. There are concerns regarding the safety profile of this drug combination due to incidents of human misuse/abuse. In this paper, we discuss the abuse liability of this drug combination based on currently available scientific evidence...

Based on recommendations from the World Health Organization (WHO), the French addictovigilance network was set up since 1990, in order to assess and to monitor the potential for abuse and dependence of psychoactive substances. This network composed of 13 addictovigilance centers implemented in medical pharmacology departments of French university hospitals has developed specific pharmacoepidemiological tools repeated each year so as to lead us to updated pharmacological indicators related to drug abuse. As a single source may not be informative enough, the French addictovigilance network consider simultaneously a range of indicators focusing on health insurance database, health professional sentinel networks, characteristics of psychotropic consumptions and analysed them from a medical and pharmacological point of view combined to pharmacodynamic and pharmacokinetic data...
