Where PsycheDB's data comes from, and the licences that apply.
Every compound page carries a numbered list of the sources behind its data. Wherever possible we trace a fact to the primary scientific literature or a public record rather than to a secondary encyclopaedia. This page sets out the sources we rely on and the terms under which their material is used.
How we cite
Individual facts and measurements are distinct from the wording, figures and databases in which they are published. Copyright, database rights and source-specific terms may apply to reused material. All descriptive text on PsycheDB is written in our own words, and we cite the underlying measurement or record so a reader can verify it. Quantitative claims are linked, where one exists, to the primary study that first reported them or to a public-domain regulatory record.
Sources and their licences
Peer-reviewed literature (PubMed / DOI). Cited under normal academic practice: we report findings and link to the article, and do not reproduce article text.
PubChem (US National Library of Medicine). Used for identifiers and physicochemical data. Contributor-supplied content can carry its own copyright and reuse conditions. See the NCBI policies and the attribution attached to each record.
FDA labels, DailyMed and DEA schedules. Used for pharmacokinetic, metabolism and legal-status facts. Hosting on a government website does not by itself remove third-party rights.
European Medicines Agency (EMA). EMA owns copyright in its content and generally permits reuse with attribution, subject to its legal notice and third-party exceptions.
GOV.UK controlled-drugs list. Open Government Licence v3.0 (attribution).
Gesetze im Internet (BtMG, NpSG). German legislation, not protected by copyright (Section 5 UrhG).
IUPHAR/BPS Guide to PHARMACOLOGY (GtoPdb). Content licensed CC BY-SA 4.0; the underlying database under the ODbL. Used with attribution, in the form its maintainers request: Harding SD, Armstrong JF, Faccenda E, et al. (2024). The IUPHAR/BPS Guide to PHARMACOLOGY in 2024. Nucleic Acids Research 52(D1):D1438–D1449. Each compound page also links the specific ligand entry used.
Wikipedia. Text licensed CC BY-SA 4.0 by its contributors. Used with attribution; each compound page links the specific article used.
PsychonautWiki. Text licensed CC BY-SA 4.0 by its contributors. Used with attribution, mainly for effect and dose-range information that has no equivalent in the primary literature.
PiHKAL and TiHKAL (A. and A. Shulgin). Copyrighted works. We use only factual data such as dose and duration; none of the authors' prose is reproduced.
Attribution and ShareAlike
Several of the sources above are offered under Creative Commons Attribution-ShareAlike (CC BY-SA 4.0). We attribute them here and, on each compound page, link the specific source used and label its reuse licence next to it, so the licence travels with the material.
Our descriptions are our own summaries written from the underlying facts, not reproductions of any source's wording, so no CC BY-SA text is carried over. In the rare case that a passage does adapt CC BY-SA material rather than merely restating a fact, that adaptation is indicated and the passage remains available under CC BY-SA 4.0.
All other text, structure and compilation on PsycheDB is © PsycheDB. Third-party material is used as-is, with no warranty from us as to its accuracy. Nothing on this page restricts the rights the licences above grant you in the original third-party material.
