The popularity of CBD oil is constantly increasing due to its medicinal value. The opposite component to CBD is the cannabinoid THC, which is also found in cannabis and is known for its psychoactive effect. Many people, including scientists and healthcare providers, have already found that CBD oil is completely safe for both adults and children. Thanks to its medicinal effects on different types of health problems, CBD oil received approval from the WHO (World Health Organization) in December 2017. However, more studies and research are still lacking. The reason for this growing popularity naturally lies in the wide range of health benefits that this product has. More and more people have started using, or have been using, CBD oil as a natural food supplement.
