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 may copy, modify, redistribute, and use that material commercially without asking permission or giving attribution.
There are important exceptions: the source code is MIT licensed, subjective-effect replication media remains controlled by its creators or rightsholders, legacy trip reports remain controlled by their authors, TripSit interaction data keeps TripSit's terms, and ProtestKit reagent-test data is not licensed by dose.wiki. Use the matrix below before republishing anything outside the core article dataset.
Contents
1. Quick answer
- dose.wiki-authored article prose and structured fields.
- The downloadable
SubstanceIndex.jsonsnapshot and schema. - Molecule SVGs generated from SMILES, 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, verify the relevant terms yourself.
2. Reuse matrix
This table is the fastest way to decide what applies. It 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 | 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 | CC0 1.0 | Not required | Allowed | The downloadable dataset snapshot and dose.wiki schema/normalization work. It does not grant rights to external sources cited by articles. |
| Molecule SVG pack and manifest | CC0 1.0 | Not required | Allowed | Structure SVGs generated by dose.wiki from SMILES with RDKit, plus 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 unless an item-specific license says otherwise. 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, not the article content or third-party data. |
| 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 | Applies when the submitter accepts the report form's CC0 terms before sending the report. |
| Interaction ratings | TripSit terms | Required | Restricted | Combination data comes from TripSit and requires TripSit attribution, a link back, and their quick-reference disclaimer. Commercial use needs TripSit permission. |
| Reagent-test data | ProtestKit terms | Consult source | Consult source | Reagent results are fetched from protestkit.eu at view time and are not redistributed as part of the downloadable dose.wiki dataset. |
3. CC0 scope
The CC0 release covers dose.wiki's own copyrightable contributions: original prose, dataset compilation, schema design, normalization, generated molecule assets, and 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.
- External sources cited or linked from dose.wiki articles.
- Legacy contributor reports unless the report marker says otherwise.
- TripSit interaction data or ProtestKit reagent-test data.
- Subjective-effect replication images, videos, and audio.
- Third-party names, trademarks, logos, or 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 may use the covered code and content freely, including commercially, but may not use the "dose.wiki" name or logo in a way that implies the fork is the official site or is endorsed by it.
4. Important exceptions
Rights remain with the author unless marked otherwise.
Trip reports are contributor-authored personal accounts. Legacy reports are published on dose.wiki with permission, but they are not part of the CC0 dataset. Link to them freely; republish or use them commercially only when the report's license marker allows it or the author gives permission.
CC0 applies when the submitter accepted the form terms.
Reports submitted through the current form are dedicated to the public domain by the submitter before they are sent. A CC0 dedication cannot be revoked once a report is public; dose.wiki will still honor good-faith requests to correct attribution, update identifying details, or remove a report from dose.wiki itself, but cannot retract copies already made elsewhere.
Rights stay with the creator or rightsholder.
Subjective-effect replication images, videos, and audio are credited to their creators when known. dose.wiki does not claim ownership of those files and does not place them under the site's CC0 dataset license. Reuse depends on the creator's permission or the license attached to the individual file.
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.
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.
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 two separate paths. This section covers text and index material; replication media is handled as creator-retained media above.
The Subjective Effect Index is a work authored by Josie Kins. It continued to be developed independently after PsychonautWiki, including through Effect Index. dose.wiki includes this index material in its CC0 release to the extent it reflects Josie Kins / dose.wiki authorship.
Substance-article "Subjective effects" sections are handled separately. Where dose.wiki restores these sections from earlier PsychonautWiki versions, it works only from Internet Archive captures dated on or before August 31, 2016, and includes only material dose.wiki has a good-faith basis to treat as Josie Kins' own authorship. Contributions made after that boundary, and edits by others that dose.wiki does not have the right to dedicate, are excluded. The cutoff is a rights boundary, not a measure of how current the information is; substance content is reviewed and updated independently of it.
Across the recovered subjective-effect attribution set on substance pages, the dated sections are early-weighted rather than merely cutoff-compliant.
Recovered date badges
All 97 of 97 are August 2016 or earlier — 100% inside the boundary.
2015 or earlier 69/97 (71.1%)
Earliest recovered sections
Jan-Jul 2016 2/97 (2.1%)
Still before August
August 2016 26/97 (26.8%)
Latest included captures
Counts are generated from the live dataset, not hand-written, and will shift as more sections are recovered. Every capture behind these numbers is listed with its Archive.org link in the provenance manifest (JSON).
Disregard Everything I Say
Early effect documentation.
PsychonautWiki
Structured collaborative reference.
Effect Index
Dedicated subjective-effect index.
dose.wiki
Current maintained corpus.
The Subjective Effect Index continued on its own track through Effect Index and dose.wiki; the August 31, 2016 cutoff applies to article effect sections recovered from PsychonautWiki captures.
6. Source code
The website source code and tooling are released under the MIT License. MIT lets you use, copy, modify, distribute, sublicense, or sell copies of the software, including in commercial and closed-source projects.
Keep the MIT copyright and permission notice in copies or substantial portions of the code.
MIT applies to the software. dose.wiki-owned content and data are CC0, while contributor reports and third-party data keep their separate terms.
7. Attribution examples
Attribution is optional for CC0 material. If you want to credit dose.wiki or need to keep third-party data and media labels clear, these examples are safe starting points.
Includes material from dose.wiki (https://dose.wiki), released under CC0 1.0.
Includes CC0 material from dose.wiki. Interaction data from TripSit; follow TripSit terms: non-commercial use, attribution, link back, and quick-reference disclaimer.
Replication media by [creator]. Rights remain with the creator or rightsholder unless the item states another license.
| You want to | What applies |
|---|---|
| Build a free or paid app from the dataset | Allowed under CC0 for covered dose.wiki material. If you display interactions, follow TripSit's separate terms. |
| Use article text in a book, video, course, or dataset | Allowed under CC0 for dose.wiki-authored text. Credit is optional. |
| Reuse a trip report | Check the report's marker. Legacy reports are author-retained unless marked otherwise; report-form submissions are CC0. |
| Reuse a subjective-effect replication | Credit the creator and follow the item-specific license or ask the creator/rightsholder for reuse permission. |
| Reuse interaction ratings | Follow TripSit's terms and ask TripSit about commercial use. |
| Reuse reagent-test results | Get reuse permission or terms from ProtestKit; dose.wiki does not license that data. |
| Fork the website | Code is MIT; covered article content, data, and molecule assets are CC0. |
8. Full terms
Canonical license summaries and source links for each layer.
CC0 1.0 Universal - covered content, data, and molecule assets
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. Covered material may be copied, modified, distributed, and used commercially without permission or attribution. It is provided without warranties.
Summary and legal code: creativecommons.org/publicdomain/zero/1.0 (legal code).
MIT License - source code
MIT License Copyright (c) 2026 Josie Kins / dose.wiki Permission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the "Software"), to deal in the Software without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the Software, and to permit persons to whom the Software is furnished to do so, subject to the following conditions: The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software.

IN NO EVENT SHALL THE AUTHORS OR COPYRIGHT HOLDERS BE LIABLE FOR ANY CLAIM, DAMAGES OR OTHER LIABILITY, WHETHER IN AN ACTION OF CONTRACT, TORT OR OTHERWISE, ARISING FROM, OUT OF OR IN CONNECTION WITH THE SOFTWARE OR THE USE OR OTHER DEALINGS IN THE SOFTWARE.
Replication media - creator and rightsholder terms
Subjective-effect replication images, videos, and audio remain owned by the original creator or rightsholder unless an individual file states a different license. dose.wiki's default policy is to credit the creator when known, preserve source links when available, and treat reuse rights as item-specific.
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. Where the original hosting service has since shut down and no attribution survived, an item is shown as creator unknown rather than credited to dose.wiki; those items are the ones most likely to need correcting.
If a replication file is miscredited, missing a source link, or should be removed, email contact@dose.wiki with the item title, creator name, and preferred correction.
Trip reports - contributor terms
Legacy trip reports are not part of the CC0 dataset. Rights remain with the original author unless the individual report shows a more permissive license marker.
Reports submitted through the current report form are dedicated to the public domain under CC0 by the submitter when they accept the form terms. That dedication cannot be revoked once the report is public and copies exist outside dose.wiki; removal requests apply to dose.wiki only.
TripSit terms - interaction data
TripSit combination data is separate from dose.wiki's CC0 dataset. TripSit describes reuse as free for non-commercial purposes when users credit TripSit, link back to the combination page or combo.tripsit.me, and include a quick-reference disclaimer. Commercial use requires TripSit permission.
Source: wiki.tripsit.me/wiki/Drug_combinations and combo.tripsit.me.
ProtestKit terms - reagent-test data
Reagent-test data is fetched from protestkit.eu and is not redistributed in the dose.wiki dataset. dose.wiki does not grant reuse rights for this data; consult ProtestKit directly before republishing it.
Source: protestkit.eu.
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'd like changed.
