1) Source Hierarchy
We prioritize:
- Systematic reviews & meta-analyses (e.g., Cochrane)
- Clinical guidelines & consensus statements
- Peer-reviewed trials & observational studies
- Government/health-agency data (e.g., WHO, CDC)
- Reputable secondary explainers for context (clearly labeled)
2) Claim-by-Claim Verification
- Every quantitative claim (e.g., onset times, prevalence) requires a primary source or a high-quality systematic review.
- Health or legal claims trigger medical and/or legal review prior to publication. See Editorial Standards.
- We quote precisely or paraphrase faithfully and provide inline citations.
3) Bias & Conflict Controls
- Editors and reviewers disclose relevant relationships; see How We Review Products for product-specific COI rules.
- We avoid pay-for-placement and label affiliate links where used.
4) Plain-Language Integrity
- We translate technical findings into clear, actionable guidance without overstating certainty.
- Jargon links to the Cannabis glossary.
5) Updates & Corrections
- Each page shows a Last Updated date.
- Substantive corrections add an Update Note with what changed and why, also summarized in Research Updates.
6) What We Don’t Do
- We don’t present marketing claims as facts.
- We don’t use single low-quality studies to make broad recommendations.
