Chronic stress affects more and more people, and many are looking for natural solutions. Among them, CBD is attracting the attention of scientific research. Without making any medical claims, let’s explore what studies say about it.

CBD, a compound being studied for its role in stress

Cannabidiol (CBD) is one of the many compounds found in hemp. Unlike THC, it does not have a psychotropic effect. Among other things, it acts on the endocannabinoid system, a network of receptors involved in regulating mood, sleep and stress.

What some studies show

Effects on anxiety and the stress response

A study published in Neurotherapeutics (2015) observed that CBD could influence certain areas of the brain associated with managing fear and anxiety, notably the amygdala and the prefrontal cortex (PubMed 24923339).

In 2019, clinical research by the National Center for Biotechnology Information (NCBI) involving 72 patients showed that 79% of them reported a reduction in their anxiety levels after one month of taking CBD (PubMed 30624194). However, the authors point out that these results need to be confirmed by larger-scale controlled trials.

Social stress and performance

Brazilian researchers studied the impact of CBD on stress related to public speaking. In this experiment, published in the Journal of Psychopharmacology (2011), participants who received 300 mg of CBD showed a notable reduction in physiological signs of stress compared with the placebo group (PubMed 21307846).

Biological mechanisms under study

Several recent studies suggest that CBD could act on serotonin receptors (5-HT1A), which are involved in regulating anxiety. It could also modulate the production of cortisol, the stress hormone. However, these effects remain exploratory.

Key points

CBD does not “treat” stress, but it is being studied for its potential to support emotional balance.
The available studies are promising, but are often limited by sample size.
Researchers emphasise the need for long-term clinical trials to confirm these observations.

The legal framework in Switzerland

In Switzerland, CBD is legal as long as the product contains less than 1% THC. It is not considered a medicine and therefore cannot be sold as such. Gaiabis products strictly comply with this regulation and place the quality and characteristics of each product reference first.
