What is the difference between CBD and H4-CBD?

The names reveal that the two cannabinoids are very similar, but they are not the same. CBD and H4-CBD are said to have different effects. They are similar in structure, but the active center is hydrogenated. Therefore, it can be assumed that the effects are also different. Hexahydrocannabidiol is said to be 100 times more potent than CBD. In addition, CBD acts on CBD2 receptors and H4-CBD acts more on CBD1 receptors.
