Novel psychoactive substances encompass a wide variety of drugs, including synthetic cannabinoids, cathinone derivatives, psychedelic phenethylamines, novel stimulants, synthetic opioids, tryptamine derivatives, dissociatives, piperazines, GABA receptor agonists, prescribed medications, psychoactive plants, and performance-enhancing drugs. Users are often drawn to them for intense psychoactive effects and their likely undetectability in routine drug tests. These substances act on neurotransmitter pathways such as dopamine, cannabinoid CB1, GABA-A/B, 5-HT2A, glutamate, and kappa opioid receptors—systems whose imbalance is linked to mental health conditions. The paper provides psychiatrists with updated knowledge on the clinical pharmacology and psychopathological consequences of these drugs, along with a brief overview of clinical management.
