Since the CBD molecule is the same CBD molecule in hemp and marijuana, it doesn’t matter how or where you get your CBD molecule, except to the legal system especially with marijuana CBD. What is important about CBD is that you do NOT take CBD in a single or isolated form if you want to experience the maximum results.
The reason for NOT ingesting a single cannabinoid is because of the entourage effect. The best and most efficient CBD Products will have a blend of many other Cannabinoids extracted from the whole plant, among other ancient wonders. More Cannabinoid diversity will bring a more holistic effect for the results you seek to achieve with hemp CBD.
Full Spectrum CBD with many other cannabinoids and compounds in the product, is far more effective for what ever issue you are trying to address with CBD. From a legal standpoint. CBD made from Hemp is legal to sell in all 50 states. CBD from marijuana is controlled and, in many cases, illegal as stated by the DEA.
