New psychoactive substances: a review and updates Abu Shafi, Alex J. Berry, Harry Sumnall, David M. Wood and Derek K. Tracy Therapeutic Advances in Psychopharmacology, 2020, Vol. 10, 1–21. Doi : 10.1177/2045125320967197 Abstract : New psychoactive substances (NPS) are a heterogeneous group of substances. They are associated with a number of health and social harms on an individual and societal level. NPS toxicity and dependence syndromes are recognised in primary care, emergency departments, psychiatric inpatient and community care settings. One pragmatic classification system is to divide NPS into one of four groups: synthetic stimulants, synthetic cannabinoids, synthetic hallucinogens and synthetic depressants (which include synthetic opioids [...]

Pascali, Paolo Fais, Guido Pelletti, Andrea Gabbin, Giorgia Franchetti, Giovanni Cecchetto and Guido Viel Life, 2021, 11, 440, 1-17. doi : 10.3390/life11050440 Abstract : Novel psychoactive substances (NPS) represent a severe health risk for drug users. Even though the phenomenon has been growing since the early 2000s, the mechanisms of action of NPS at the receptors and beyond them are still scarcely understood. The aim of the present study was to provide a systematic review of the updated knowledge regarding the molecular [...]

Penders Current Psychiatry Reviews, 2016, Vol. 12, No. 2, 1-3. DOI: 10.2174/1573400512666160216234850 Abstract : Hallucinogen Persistent Perception Disorder (HPPD) is considered an “uncommon” disorder described in association with use of hallucinogens such as LSD, mescaline and psilocybin. Despite multiple mentions of persistence of visual disturbances reported by users on online forums, clinicians may not be aware of this complication. There have been few descriptions of HPPD in association with use of new psychoactive substances (such as 2C-E). Increasing use of these designer stimulants places [...]

Tracy Therapeutic Advances in Psychopharmacology, 2015, Vol. 5, (2), 97–132 DOI: 10.1177/2045125314559539 Abstract : There has been growing clinical, public, and media awareness and concern about the availability and potential harmfulness of so-called ‘legal highs’, which are more appropriately called new or novel psychoactive substances (NPS). A cat-and-mouse process has emerged wherein unknown chemists and laboratories are producing new, and as yet nonproscribed, compounds for human consumption; and as soon as they are banned, which they inevitably are, slightly modified analogues are produced to [...]
