Plain-English CBD guides · UK-focused · Educational information, not medical advice
The guides
Evergreen guides organised by topic. Each topic page gives an overview and links to the guides inside it as they are published.
Start with these
Our five core topics. Each has an overview page, with in-depth guides added one at a time.
Core topic
What CBD is, how it differs from THC and hemp, and the terms you will see on products.
Core topic
What is known about side effects and medicine interactions, what UK guidance says about amounts, and who should avoid CBD.
Core topic
How UK rules on THC, novel foods and medicinal claims apply to CBD, with a separate US section.
Core topic
What studies have looked at, how strong the evidence is, and how to read a study for yourself.
Core topic
Reading strengths, servings and certificates of analysis, and spotting marketing red flags.
Guides are published one at a time and written to our editorial approach. Where a guide makes a factual or health statement, its sources are linked on the page.
A regulator or guideline position, or consistent findings across systematic reviews.
Limited, small or early studies. We say who was studied and what the limits are.
Personal reports. Clearly labelled and never used as evidence that something works.
