Licensing and reuse
What you can reuse, what needs attribution, and what dose.wiki does not license.
Most dose.wiki-authored material is released under CC0 1.0 Universal. You can copy, modify, redistribute, and use that material commercially without asking permission or giving attribution.
The source code and several kinds of contributor and third-party material keep their own terms. The reuse matrix in section 2 is the authoritative inventory. Before you republish anything, check the matrix.
1. Quick answer
- dose.wiki-authored article prose and structured fields.
- The downloadable
SubstanceIndex.jsonsnapshot and schema, apart from itsinteractionsfield. - Molecule structure SVGs drawn or laid out by dose.wiki, plus their manifest.
- Trip reports submitted through the current report form.
- Legacy trip reports, where rights remain with the author.
- Subjective-effect replication images, videos, and audio.
- TripSit interaction ratings and combination guidance.
- Reagent-test data fetched from protestkit.eu.
- External sources cited by articles, trademarks, and third-party names.
Not legal advice. This page describes dose.wiki's licensing intent and the reuse terms we apply to our own material. If your use is sensitive, commercial, or jurisdiction-specific, check the relevant terms yourself.
2. Reuse matrix
This table separates material dose.wiki can license from material that belongs to contributors or third-party projects.
| Material | Terms | Attribution | Commercial use | Notes |
|---|---|---|---|---|
| dose.wiki-authored article content | CC0 1.0 | Not required | Allowed | CC0 covers dose.wiki's own copyrightable contributions to summaries, pharmacology, tolerance, harm potential, history, legality, dosage, duration, and related article fields. |
Structured dataset SubstanceIndex.json | Mixed | Interactions only | Except interactions | CC0 covers the downloadable snapshot, the dose.wiki schema, and the normalization work. Every article document also carries an interactions object built from TripSit combination guidance, which keeps TripSit's terms (section 4). Strip or separately license that field before commercial reuse. CC0 grants no rights to external sources cited by articles. |
| Molecule SVG pack and manifest | CC0 1.0 | Not required | Allowed | Structure SVGs made by dose.wiki: an automatic layout from SMILES, then redrawn by hand or aligned to a class template, rendered with a dose.wiki fork of OpenChemLib. Includes the molecule metadata manifest. |
| Subjective-effect replication media | Creator retained | Always credit | Ask creator | Images, videos, and audio that recreate subjective effects remain owned by their original creators or rightsholders. No open license covers them and none is CC0; reuse is the artist's call unless an individual item states its own license. dose.wiki displays and credits them; it does not relicense them. |
| Website source code | MIT | Keep notice | Allowed | MIT covers the application code and tooling only (section 6). |
| Legacy trip reports | Author retained | Per report | Ask author | Reports already on the site are contributor-authored personal accounts. Reuse outside ordinary linking or quotation depends on the report's marker or the author's permission. |
| New report-form submissions | CC0 1.0 | Not required | Allowed | CC0 applies when the submitter accepts the report form's CC0 terms before they send the report. |
| Interaction ratings | TripSit terms | Required | Restricted | Combination data comes from TripSit. Reuse follows TripSit's own terms (section 4). |
| Reagent-test data | ProtestKit terms | Consult source | Consult source | dose.wiki fetches reagent results from protestkit.eu when you view an article. The downloadable dataset does not contain them. |
3. CC0 scope
Published facts and the writing used to explain them are different things. In U.S. copyright law, copyright generally does not protect the underlying facts, but it can protect an author's wording and original selection or arrangement.
Where dose.wiki holds copyright or database rights in its own writing, editorial contributions, schema, or compilation, it waives those rights through CC0 to the extent the law allows. The rest of this page calls these the covered material. The dedication applies to those contributions, not to the source works used to prepare them. Quoted passages, third-party media, and separately licensed data keep their own terms, whether they appear on a page or in a download.
- Original article prose.
- The dataset compilation and the schema design.
- Normalization work.
- Generated molecule assets.
- Report-form submissions whose contributors accepted CC0 terms.
- Copy and redistribute the covered material in any format.
- Modify, translate, extract, remix, or combine it with other work.
- Use it in commercial projects.
- Skip attribution, permission requests, and share-alike obligations.
The carve-outs detailed in section 4, external sources cited or linked from articles, and third-party names, trademarks, logos, and site identities.
Attribution is appreciated, not required. A link to dose.wiki helps other people find the source dataset, but CC0 does not require credit.
CC0 waives copyright, not trademark. Forks can use the covered material and the source code freely, including commercially. A fork must not use the "dose.wiki" name or logo to present itself as the official site or to claim endorsement.
4. Important exceptions
Five carve-outs do not inherit the blanket CC0 release. This section is the authoritative statement of their terms.
Rights remain with the author unless marked otherwise.
Trip reports are contributor-authored personal accounts. dose.wiki publishes legacy reports with permission, but they are not part of the covered material. Link to them freely. If the report's license marker permits it, or if the author agrees, you can republish or commercially use a report.
CC0 applies when the submitter accepted the form terms.
The submitter dedicates the report to the public domain before the form sends it. A CC0 dedication cannot be revoked after a report is public. dose.wiki honors good-faith requests to correct attribution, to update identifying details, or to remove a report from dose.wiki. dose.wiki cannot retract copies that other sites already made.
Rights stay with the creator or rightsholder.
No subjective-effect replication image, video, or audio file is open-licensed, and none of it is CC0. Reuse is entirely the creator's or rightsholder's call, item by item. dose.wiki credits them when known, and many items have no recorded rightsholder at all — treat those as unknown rather than free. The full terms, provenance notes, and the credit-correction route are in section 8.
The combination ratings shown on dose.wiki come from TripSit's drug-combination guidance. dose.wiki does not place that data under CC0. Reuse must follow TripSit's terms: non-commercial use, attribution, a link back to TripSit or combo.tripsit.me, and a note that the information is only a quick reference. Commercial use needs TripSit permission.
Reagent color reactions are fetched from protestkit.eu when an article is viewed. They are not included in the downloadable dataset, and dose.wiki does not grant reuse rights for them. Consult ProtestKit directly before republishing reagent-test data.
SubstanceIndex.json carries the TripSit interactions field, and EffectIndex.json carries the replication media it references — the audio_replications entries plus the gallery_order and social_media_image image references — credited to their creators. If you scrape full pages instead, also check your capture for reagent data, replication media, and legacy reports. None of those inherit CC0 terms.5. Subjective effects provenance
Subjective-effects material has a longer and more distributed publication history than the rest of the dataset, and it reaches dose.wiki by several separate paths. This section covers text and index material. Replication media stays creator-retained, as section 4 states.
The Subjective Effect Index is a work authored by Josie Kins. She created it on her blog Disregard Everything I Say in 2011, before PsychonautWiki existed, and continued to develop it independently afterwards, including through Effect Index. dose.wiki includes this index material in its CC0 release to the extent it reflects Josie Kins / dose.wiki authorship.
dose.wiki handles substance-article "Subjective effects" sections separately, and they are currently a mixture of two paths. Where an earlier Josie Kins version exists, dose.wiki restores it, working only from Internet Archive captures dated on or before August 31, 2016, and including only material it has a good-faith basis to treat as her own authorship. It excludes contributions made after that boundary, and edits by others that it does not have the right to dedicate. The date is a rights boundary, not a measure of how current the information is. dose.wiki reviews and updates substance content independently of the boundary.
Where no such section exists, dose.wiki synthesizes one from source material gathered across the internet, the same way it writes the other article sections. Those runs exclude every project Josie Kins was involved in — Disregard Everything I Say, PsychonautWiki, and Effect Index — to avoid a conflict of interest. Synthesized sections are dose.wiki's own authorship and fall under the covered material. dose.wiki intends to replace these sections entirely with Mindstate Design Labs data.
Most of the recovered sections on substance pages are dated well before the boundary, not clustered against it.

CC0 1.0 Universal - the covered material
CC0 places a work as completely as possible into the public domain. The person who associates a work with CC0 waives copyright and related rights worldwide to the extent allowed by law. You can copy, modify, distribute, and commercially use the covered material without permission or attribution. It comes without warranties.

Replication media - creator and rightsholder terms
Replications accompany the effect descriptions as visual and auditory examples. They give readers another way to understand experiences that can be difficult to describe in words. Creator credits and source links, where known, let readers find the work in its original context.
Subjective-effect replication images, videos, and audio remain owned by the original creator or rightsholder unless an individual file states a different license. None of this library is open-licensed and no part of it is included in the CC0 dedication. dose.wiki's default policy is to credit the creator when known, preserve source links when available, and treat reuse rights as the rightsholder's to grant. The public replications API reports a rights status per item — explicit license, creator-retained, or unknown — so check the item itself rather than assuming any dataset's terms carry over.
Much of this library was originally published on Effect Index, and reaches dose.wiki through the Effect Index archive. Recovered files keep the creator credit and source link recorded for them there. Some original hosting services shut down, and their attribution did not survive. dose.wiki shows those items as creator unknown. It does not credit them to dose.wiki. These items are the most likely to need correction.
If a replication file is miscredited, has no source link, or must be removed, email contact@dose.wiki with the item title, creator name, and preferred correction.
For miscredited or disputed replication media, report-removal requests, trademark or name-use concerns, or any other rights question about material on dose.wiki, email contact@dose.wiki. Include the article or item, and what you want changed.
