New Psychoactive Substances (NPS) – a Challenge for the Addiction Treatment Services

Pharmacopsychiatry April 25, 2017 Norbert Scherbaum, Fabrizio Schifano, Udo Bonnet 46 citations

Hundreds of new psychoactive substances (NPS) have been identified in Europe, mainly synthetic cannabinoids and new synthetic stimulants like cathinones. These are often developed by modifying basic chemical structures such as phenethylamine or tryptamine. Although their pharmacology and toxicology are hardly known, they are sold online as "bath salts" or "incense mixtures" and advertised as "legal highs." Little is known about the prevalence of NPS use, but some molecules may cause severe adverse reactions. Unlike cannabis, synthetic cannabinoid users may experience epileptic seizures, loss of consciousness, and persisting psychopathological disorders. Future studies should inform better-tailored management strategies.

Prevalence of Novel Psychoactive Substance (NPS) Use in Patients Admitted to Drug Detoxification Treatment

Frontiers in Psychiatry July 7, 2020 Michael Specka, Thomas Kuhlmann, Jürgen Sawazki et al. 42 citations

Among patients undergoing in-patient detoxification from illicit drugs in Germany, use of novel psychoactive substances (NPS) was rare. About 32% reported having tried synthetic cannabimimetics at least once in their lifetime, but usually only a few times, and nearly no one had used them in the 30 days before admission. Urine analysis confirmed the low recent use. In contrast, lifetime and current use of opiates, alcohol, cocaine, benzodiazepines, and cannabis was high. An important reason given for trying NPS was that they were not detected by drug testing in prisons or treatment facilities. A notable finding was that 18% reported regular unprescribed pregabalin use during their lifetime, and 20% had recently used it, indicating diversion of legal medications is a serious concern.

Differences between users' and addiction medicine experts' harm and benefit assessments of licit and illicit psychoactive drugs: Input for psychoeducation and legalization/restriction debates.

Frontiers in psychiatry January 1, 2022 Udo Bonnet, Michael Specka, Ann-Kristin Kanti et al. 4 citations

Substance-dependent users and addiction medicine experts rank the harms of traditional illicit drugs (heroin, cocaine, amphetamines) highest, with alcohol and benzodiazepines also in a top-harm tier. Both groups place methadone, nicotine, and cannabis in the midrange, and buprenorphine and psychotropic mushrooms at the lowest harm level. Users rate the benefits of traditional illicit drugs, cannabis, and nicotine more positively than experts do, while experts judge methadone as significantly less harmful than users do. Users attribute the most benefits to buprenorphine, methadone, and cannabis, likely reflecting that over 50% of the user sample sought opiate detoxification treatment. The findings inform psychoeducation and policy debates.
