In recent years, the increase in cannabidiol (CBD) sales in Europe has raised questions regarding the legal status of this product, as well as its safety of use. Consumers seem to be looking for solutions to various health issues. However, the scientific reality is much more nuanced. The European CBD market emerged in Switzerland in 2016 and subsequently expanded across the continent. This expansion has been facilitated by the establishment of delta-9-tetrahydrocannabinol (THC) concentration limits for these products. However, the current market offers a diverse range of CBD products, often lacking clear information on raw materials, product concentrations and recommended dosages. Regulating these products is challenging, as the appropriate classification of CBD remains uncertain. CBD products are in high demand worldwide, with many people seeking alternative treatments for medical conditions or general health and well-being benefits. However, the use of CBD products often relies on self-medication and lacks sufficient scientific evidence. Improved communication between patients and healthcare professionals is needed to ensure informed decisions and address potential interactions with other medications. Scientific evidence on CBD is currently limited and the efficacy of CBD-containing products has only been proven in clinical trials for Epidyolex® as an add-on therapy. There is no consensus on the long-term safety, appropriate dosage, schedules or administration routes for CBD. Health claims associated with CBD are not consistent with the available scientific research, which is still in its early stages. Further clinical research is needed to establish the efficacy and safety of CBD in various medical conditions. The enthusiasm surrounding CBD-based products should be tempered by the limited scientific evidence of their efficacy, the inadequacy of patient expectations, regulatory concerns and potential drug interactions.
