New psychoactive substances (NPSs) often emerge on the illicit drug market with limited pharmacological or toxicological data. Synthetic cathinones are the second largest NPS group, often mimicking the effects of classical stimulants such as cocaine and methylenedioxymethamphetamine (MDMA). Such stimulants primarily target dopamine (DAT), norepinephrine (NET) and serotonin (SERT) transporters,...
Abstract Designer benzodiazepines (DBZDs) are a class of new psychoactive substances (NPS) designed as legal alternatives to prescription BZDs. Bromazolam has been the most prevalent DBZD detected on the recreational market around the world; however, a new DBZD, ethylbromazolam (8-bromo-1-ethyl-6-phenyl-4 H-[1,2,4]triazolo[4,3-a][1,4]benzodiazepine; also known as bromoethylazolam) has recently...
Abstract Background and Purpose New synthetic cannabinoid receptor agonists (SCRAs) are associated with severe adverse effects, including unexpected psychiatric symptoms. These compounds are mainly active through their potent agonism on the cannabinoid receptors CB 1 and CB 2 . Recently, evidence of the direct interaction of some SCRAs with the serotonergic 5‐HT receptors has emerged....
Abstract Semi‐synthetic cannabinoids (SSCs) including hexahydrocannabinol (HHC) are emerging on the drug market and sold openly as purportedly legal replacements for cannabis and Δ9‐THC. By the beginning of 2024, 24 European countries had identified HHC, often sold openly in edibles (foods/candy), vapes and low‐THC cannabis flowers and resins. The SSC market is developing rapidly, with HHC...

New psychoactive substances (NPS) are introduced on the illicit drug market at a rapid pace. Their molecular targets are often inadequately elucidated, which contributes to the delayed characterization of their pharmacological effects. Inspired by earlier findings, this study set out to investigate the µ opioid receptor (MOR) activation potential of a large set of psychedelics, substances which...
New psychoactive substances (NPS) appear on the recreational market on a monthly basis, with unclear toxicology, resulting in an increasing number of fatalities. Identification of drug targets and potencies is crucial for understanding and treating intoxications and for scheduling processes. In this study 60 NPS and metabolites belonging to opioids, cannabinoids and serotonergic hallucinogens...
