It probably does help, to varying degrees, depending on the amount of CBD in a persons system and how much alcohol was consumed. CBD has great neurological health benefits and should surely help prevent damage to and grow new brain cells. Vitamin C and proteins are known for helping with that, and CBD is said to have an effect on the cells in your body as if it were vitamin C on steroids. Of course, drinking even more alcohol with unrealistic expectations would probably not be a good idea, but I'll give it a try and let you know, if I can remember to! lol
