A lexicon for psychedelic research and treatment

Drug Science Policy and Law September 1, 2025 David Nutt, David Erritzøe, Anne Katrin Schlag et al. 9 citations

The field of psychedelic research lacks standardized terminology for clinical development, dosing, safety monitoring, and regulatory classification. A comprehensive framework is proposed that classifies psychedelics by pharmacology (serotonergic, glutamatergic, kappaergic, GABAergic, and atypical), introduces dose-dependent categories (microdose, minidose, mididose, macrodose), and standardizes terms like “short-acting” with specific pharmacokinetic parameters. Safety considerations include cardiovascular and psychological effects, with risk mitigation protocols for higher-risk compounds like ibogaine. A three-phase treatment model—preparation, dosing, and integration—is recommended as a minimum standard. The lack of comparative research on psychotherapy modalities is identified as a critical gap.

A comparative study of the harms of nitrous oxide and poppers using the MCDA approach

Drug Science Policy and Law January 1, 2022 Plinio Ferreira, Adam Winstock, Anne Katrin Schlag et al. 9 citations

Nitrous oxide (laughing gas) and alkyl nitrites (poppers) rank among the least harmful recreational drugs when assessed on 16 criteria including dependence, injury, and economic cost. An expert panel using Multi-Criteria Decision Analysis scored nitrous oxide at 6 and poppers at 5 on a 0–100 overall harm scale, placing them just above magic mushrooms (psilocybin). Nitrous oxide scored higher for dependence, environmental damage, mental impairment, and family adversities; poppers scored higher for injury, drug-related damage, economic cost, and mortality. The findings aim to inform UK policy decisions, as nitrous oxide possession is not currently controlled under the Misuse of Drugs Act.
