CBD research: 5 questions to ask about a scientific study

Cannabinoid research is fascinating, but a headline rarely tells the whole story. These five questions help put a study into perspective.

1. What was studied?

CBD, THC and the body’s own endocannabinoids are different substances. Findings about one cannot simply be applied to another. The dose and method of administration also matter.

2. Cells, animals or people?

A laboratory experiment may reveal a possible mechanism. That alone does not establish an effect in humans. Clinical studies also need to be assessed by their participants, comparison group and duration.

3. How robust is the result?

Look at sample size, uncertainty and dropouts. An association does not automatically establish cause. Have other researchers found similar results, and does a systematic review support the conclusion?

4. Were drawbacks investigated?

Read about adverse effects, limitations and missing long-term data as well as possible benefits. An absence of reported problems does not always establish safety.

5. Who is behind the study?

Find the original publication, its date, funding and conflicts of interest. Personal experiences may matter to individuals but cannot replace a controlled study.

From curiosity to knowledge

The NIH describe a broad research field covering cannabis constituents and the endocannabinoid system. Curiosity works best alongside a precise understanding of what findings can and cannot show. This article discusses no specific commercial products and makes no treatment recommendation.
