Novel psychoactive substances include synthetic cannabinoids, cathinone derivatives, psychedelic phenethylamines, novel stimulants, synthetic opioids, tryptamine derivatives, phencyclidine-like dissociatives, piperazines, GABA-A/B receptor agonists, a range of prescribed medications, psychoactive plants/herbs, and a large series of performance and image enhancing drugs. Users are typically attr...

Historically, ecstasy tablets contained 3,4-methylenedioxymethamphetamine (MDMA) as the psychoactive component. In recent years, the Drug Enforcement Administration (DEA) and other law enforcement agencies have seized ecstasy tablets that are comprised of psychoactive drugs or drug mixtures other than MDMA. Many jurisdictions have reported the presence of piperazine derivatives including 1-benz...

Adolescence is a period of transition from childhood to adulthood, characterized by efforts to achieve the objectives related to the expectations of the culture, as well as the requirements of the physical, mental, emotional, and social development. It has its own characteristics in the biological, psychological, and social terms, with a process of identity formation, the development of social,...

The mutual goal both Society Journal, provide a platform rapid exchange multidisciplinary knowledge on novel psychoactive substances (NPSs), addictions, their health effects.

BACKGROUND Alcohol or drug use and associated hangover may reduce workplace safety and productivity and also cause sickness absence. The aims of this study were to examine (i) the use of alcohol and drugs, and (ii) reduced efficiency at work and absence due to such use among employees. METHODS Forty-four companies were invited; half of them agreed to participate. Employees filled in a questio...

Between 2006 and 2011 a large scale research project named DRUID (Driving Under the Influence of Drugs, Alcohol and Medicines) was conducted to provide scientific knowledge for combating driving under the influence of psychoactive substances in the European Member States. As part of this DRUID-project roadside surveys have been conducted in thirteen European countries to get more insight in the...

To better understand off-target effects of widely prescribed psychoactive drugs, we performed a comprehensive series of chemogenomic screens using the budding yeast Saccharomyces cerevisiae as a model system. Because the known human targets of these drugs do not exist in yeast, we could employ the yeast gene deletion collections and parallel fitness profiling to explore potential off-target eff...

Pure psychoactive drugs and direct routes of administration are evolutionarily novel features of our environment. They are inherently pathogenic because they bypass adaptive information processing systems and act directly on ancient brain mechanisms that control emotion and behavior. Drugs that induce positive emotions give a false signal of a fitness benefit. This signal hijacks incentive mech...
