Hi, CBD is CBD no matter what the source but there are some differences between them. A good article is from ProjectCBD.org, here is the link https://www.projectcbd.org/guidance/cannabis-oil-vs-hemp-oil
From the feedback I have had from many members that have used both, CBD from cannabis strains seems more effective. CBD from hemp lacks critical medicinal terpenes and secondary cannabinoids found in cannabis oil. These compounds interact with CBD and THC to enhance their medicinal benefits.
