"The data supporting efficacy and dosing are specific to one product: Epidiolex," Bonn-Miller says. "That's not necessarily translatable to 'Joe Bob's CBD Blend.'" A CBD extract you buy online or in a dispensary will almost certainly have less CBD in it, he explains, and will contain other cannabinoids—meaning that it will work differently and will need to be dosed differently. "This is not to say that 'Joe Bob's CBD Blend' definitely isn't going to be effective for pediatric epilepsy, but it means that we need to study it before we know."
Effective in January 2017, the DEA (which typically refers to marijuana by the plant’s scientific species name, Cannabis sativa, or the Reefer Madness-era spelling “marihuana”) made a rule stating its marijuana scheduling includes “marihuana extract.” In the rule, the agency defined “marihuana extract” as an “extract containing one or more cannabinoids that has been derived from any plant of the genus Cannabis”—which would include CBD.
The final advantage in the above list of a lower cost per milligram is one worth looking into further. As previously mentioned, because a full spectrum product is derived from a whole plant ex-tract it typically costs more (you the consumer are getting more than just CBD). Chase Terwilliger, CEO of CBDistillery, adds, "It is less expensive to manufacture isolate-based products com-pared to full-spectrum products. Rather than taking advantage of a larger margin, we decided to pass the savings along to the consumers." For those looking for a pure CBD product, you will al-so be delighted to find that CBD oil made from isolate is typically less expensive than a full-spectrum product. Which brings up a final point which is to do your research on the industry standard pricing for cost per milligram to ensure you are not paying an unnecessary premium.
