Sources we rely on, in order
- Primary legal sources: statutes, bill text and votes on state legislature sites, ballot measure text, city council resolutions, court opinions, and agency rules (for example the Oregon Health Authority and Colorado's Natural Medicine Division).
- Government data: FDA, DEA, NIH, SAMHSA, CDC and state health department reports and dashboards.
- Peer-reviewed research: trials and reviews in journals such as JAMA, The New England Journal of Medicine, The Lancet and Nature Medicine, plus trial registrations on ClinicalTrials.gov.
- Established trackers and reporting: university policy trackers and reputable news outlets, used to find primary sources and for events that primary sources don't cover yet.
We don't cite shop blogs, anonymous forum posts or social media as evidence for a legal or medical claim.
Dates and re-checks
- Every guide shows the date it was last checked. The state law guide is re-checked at least monthly and after any legislative session, ballot vote or court ruling that affects psilocybin.
- News articles keep their original publish date. If a story changes later, we add an update note with the new date instead of quietly rewriting it.
- When a page says "as of" a date, that is the date we last confirmed the fact with the source.
How we write
- We separate three things that often get blurred: legal (licensed and permitted), decriminalized (still illegal, lowest enforcement priority) and illegal.
- We report what studies found, including null results and limits like small samples or short follow-up.
- We don't publish dosing instructions. Safety information focuses on drug interactions, who should avoid psilocybin, and when to get help.
- Drafts may be prepared with the help of software tools, including AI. Every factual claim is checked against the source we cite before a page goes live.
Commercial relationships
The publisher has a business relationship with My Mushroom Dispensary, an online retailer. Where a page recommends that retailer, we say so on the page. Retailer relationships never decide what a guide says about the law, safety or science, and no one can pay to be included, ranked or left out. More on how the site is funded.
Corrections
If you spot an error, contact us with the page and, if you can, a source. We review every correction request. Fixes to facts are made promptly and, for news articles, noted at the bottom of the story with the date.
