CBD, by itself, may.  However, you will get a much deeper sleep from the other cannabinoids found in hemp such as CBN.  Therefore, if you’d like to try CBD Oil for Sleep, make sure you buy Whole Plant Hemp Oil or Full Spectrum CBD Oil so you’ll get CBD plus all the other naturally occurring cannabinoids.  Think of it as taking a multivitamin.  You’re body will use what it needs and discard the rest.
