Source Policy

Sources match the type of claim being made.

Clinical efficacy claims need medical evidence. Legal access claims need legal or regulatory sources. Background sources can support context, but not replace primary evidence.

Preferred Source Hierarchy

  • Tier 1: peer-reviewed systematic reviews, randomized controlled trials, and major clinical trials for efficacy, safety, and outcomes.
  • Tier 2: regulators and government sources such as Health Canada, FDA, DEA, state and provincial colleges, and official access programs.
  • Tier 3: professional bodies, clinical guidelines, academic institutions, and consensus documents.
  • Tier 4: reputable medical publishers for background context only.

What We Avoid As Primary Sources

Clinic blogs, forums, Reddit threads, manufacturer marketing, news coverage, testimonials, and social media posts are not used as primary support for medical efficacy, safety, or legal access claims.

How Sources Are Used

We separate “what evidence suggests” from “what is legally available.” Early, small, open-label, or non-randomized studies are described with their limitations rather than presented as settled clinical consensus.
