Novel psychoactive substances (NPS) are increasingly used by young individuals for their psychoactive effects and have been frequently associated with the emergence of psychotic symptoms and schizophrenia spectrum disorders. However, it remains unclear whether NPS use directly increases the risk of psychosis onset or whether individuals with a predisposition to psychosis are more likely to...

There has been an acceleration in deaths following illicit ketamine in recent years, which are increasingly featuring complex patterns of polydrug use and socio-economic vulnerability. Policy responses must extend beyond single-substance legislative controls to encompass harm reduction, treatment integration, and social support strategies.

Abstract Xylazine, traditionally used as a veterinary sedative, has recently emerged as a new psychoactive substance, being typically ingested in combination with fentanyl derivatives and hence raising significant public health concerns. Despite its increasing prevalence, little is known about its molecular interactions with human neuroreceptors, specifically the serotonin 7 (5‐HT 7 R) and...

BACKGROUND: The widespread availability and accessibility of over-the-counter (OTC) medicines play a vital role in modern healthcare systems, enabling individuals to manage minor health concerns independently. However, certain OTC medications possess pharmacological properties that render them susceptible to misuse and abuse, including stimulants, laxatives, sedatives, and opiate-containing...

Intranasal esketamine, approved with oral antidepressants for adults with treatment-resistant depression (TRD), is the S-enantiomer of ketamine and has higher potency and affinity for N-Methyl-d-Aspartate receptors. Administered intranasally, it offers rapid absorption and onset, essential for severe depressive symptoms or suicidal impulses. Comparative studies on esketamine and ketamine's...

BACKGROUND: Ibogaine and noribogaine are psychedelic substances with dissociative properties naturally occurring in plants of the Apocynaceae family. Research has shown their efficacy in treating substance use disorders (SUD), particularly in opiate detoxification, but their efficacy and toxicity are still unclear. OBJECTIVE: This review aims to assess the anti-addictive role of ibogaine and...

Psychedelics alter the perception of reality through agonist or partial agonist interaction with the 2A serotoninergic receptor. They are classified as phenethylamines, tryptamines and lysergamides. These classes, according to the United Nations Office on Drugs and Crime (UNODC) and European Monitoring Centre for Drugs and Drug Addiction (EMCDDA), account for an important percentage of the new...

COVID-19-related disruptions of people and goods' circulation can affect drug markets, especially for new psychoactive substances (NPSs). Drug shortages could cause a change in available NPS, with the introduction of new, unknown, substances. The aims of the current research were to use a web crawler, NPSfinder®, to identify and categorize emerging NPS discussed on a range of drug...

The critical spread and dissemination of novel psychoactive substances (NPS), particularly among the most vulnerable youngsters, may pose a further concern about the psychotic trajectories related to the intake of new synthetic drugs. The psychopathological pattern of the "new psychoses" appears to be extremely different from the classical presentation. Therefore, clinicians need more data on...

BACKGROUND: The present paper provides an updated review of both the large number of new/novel/emerging psychoactive substances (NPS) and their associated psychopathological consequences. Focus was here given on identification of those NPS being commented in specialised online sources and the related short-/long-term psychopathological and medical ill-health effects. METHODS: NPS have been...

Currently different classes of psychoactive substances are easily available for abuse, including several hundred novel psychoactive substances (NPS). Some of these drugs occur naturally in plants and animals or are chemically modified from plant or animal compounds and have been abused by humans over millennia. Recently, the occurrence of a new "drug culture" (e.g., psychonauts) who consume a...

Hallucinogen-persisting perception disorder (HPPD) is a syndrome characterized by prolonged or reoccurring perceptual symptoms, reminiscent of acute hallucinogen effects. HPPD was associated with a broader range of LSD (lysergic acid diethylamide)-like substances, cannabis, methylenedioxymethamphetamine (MDMA), psilocybin, mescaline, and psychostimulants. The recent emergence of novel...

OBJECTIVES: MDAI (5,6-methylenedioxy-2-aminoindane; 6,7-dihydro-5H-cyclopenta[f][1,3]benzodioxol-6-amine; 'sparkle'; 'mindy') is a psychoactive substance, sold primarily over the Internet and in 'head' shops as a 'legal high'. Synthesised and used as a research chemical in the 1990s, MDAI has structural similarities to MDMA (3,4-methylenedioxy-N-methylamphetamine) and shares its behavioural...

5-MeO-DALT (N,N-diallyl-5-methoxytryptamine) is a psychoactive substance, sold primarily over the Internet as a 'research chemical' or 'plant food'. Although details for the synthesis of this tryptamine have been available since 2004, its use as a hallucinogenic drug has been reported only occasionally in on-line user fora. It is controlled in only a few countries world-wide. There is little...

Recently, those substances deriving from the active ingredient of the Khat plant, cathinone, have been rising in popularity. Indeed, 4-methylmethcathinone (mephedrone; 'meow meow' and others) has been seen by some as a cheaper alternative to other classified recreational drugs. We aimed here at providing a state-of-the-art review on mephedrone history and prevalence of misuse, chemistry,...
