Editorial Policy

Updated:

In short: cbd.com.tr and its English edition cbd.school do not sell or recommend products and do not give personal doses. We base every piece of health information on a peer-reviewed study or an official body. If the evidence is weak, we say so clearly.

Our aim

To guide people who are looking for treatment, without selling false hope. We explain, with sources, how CBD oil is actually used around the world, which conditions it has been shown to help and which it has not.

Independence and conflicts of interest

  • cbd.com.tr and cbd.school are produced voluntarily, with our own resources. We accept no advertising, sponsorship or partnership income from any company.
  • We don’t sell products. Our pages have no sales links, discount codes or product rankings.
  • We don’t recommend brands. We don’t accept payment to write in favor of a product or brand.
  • We mention a medicine’s licensed name only to give scientific information (for example, a medicine used in research).

Our sources

We look for information in this order:

  1. Reviews that assess many studies together (systematic reviews, meta-analyses).
  2. Studies in which patients are randomly split into two groups, with one group given the medicine and the other an inactive substance (placebo).
  3. Drug approval documents and official bodies: the Turkish Medicines and Medical Devices Agency (TİTCK), the US Food and Drug Administration (FDA), the European Medicines Agency (EMA), the European Food Safety Authority (EFSA), the World Health Organization (WHO).
  4. Smaller or uncontrolled studies and case reports. When we use these, we state that the evidence is weak.

Every piece of information is shown with its source (PubMed number, DOI or official link). If we could not check a piece of information against the full text of the article, we say so separately on the page.

How do we state the level of evidence?

  • Proven effect: Controlled studies showed a benefit. The evidence level next to it tells you how strong the evidence is.
  • May help a little: A small effect was seen, but it does not count as proof of treatment.
  • Mixed results: Some studies saw a benefit; others did not.
  • Not studied enough: There are not enough studies in humans.
  • No effect found: In studies, CBD did no better than an inactive substance (placebo).
  • May be harmful: Studies suggest it may cause harm.

We give results for pure CBD and for products that contain THC separately; an effect shown for one does not count for the other.

Definitions and examples of the grades: How do we rate the level of evidence?

Our dose policy

We don’t recommend personal doses. We show the doses used in research together with the name of the study. Our drop calculator only converts the milligrams your doctor prescribed into the number of drops in your own bottle. Your doctor decides the dose.

How do we prepare and check our articles?

  • Before publication, health articles are checked point by point against their sources.
  • We use AI tools during preparation. Everything AI finds is checked against the source itself; information without a source is not published.
  • We don’t use phrases the evidence does not support, such as "treats" or "cures."

Updates and corrections

  • Every page shows the date it was last updated.
  • When there is an important new study or a change in regulations, we update the relevant page.
  • If you spot a mistake, write to us through the contact form. We check it against the source, correct it if it is right, and update the page’s date.

Our tools and your privacy

The personal warnings tool, the drop calculator and the drug interaction checker run in your browser. The information you enter is not sent anywhere and is not saved.

Using our images

We produce the molecule, protein and anatomy images in our articles ourselves, from open scientific data: molecules from PubChem’s 3D structures, proteins from experimental structures in the RCSB Protein Data Bank, and organs from the BodyParts3D anatomy model. The source and license of the data are shown below each image.

You can use these images with a link to cbd.com.tr (CC BY 4.0). Images derived from the anatomy model are shared under the same license (CC BY-SA 4.0). For attribution, write "Image: cbd.com.tr" and link to the page where the image appears.
