That said, both Blessing and Carson warn that CBD should still be considered a drug, which means it can interact with other drugs. “CBD does interact with drugs that people are taking,” says Blessing. “So if you’re taking an opioid cough suppressant, or you’re taking serotonin-based medicine, like an SSRI, you can have strong drug interactions.” While most coffee shops are likely using doses too low to cause such interactions, Blessing says it’s something to be aware of. “If a coffee shop happened to have a way of making a product with a lot of CBD in it, then that could really interact with the medication this person is taking, and the effects they think are due to CBD could partly be due to that medication interaction,” she says.
Despite this, CBD is something nobody knows much about, and certainly nobody is monitoring it properly. CBD is widely marketed as a supplement, despite the Food and Drug Administration saying it does not qualify as such (this is because it is an active ingredient in drugs which are either approved or under investigation to be approved). CBD goes largely unregulated by the agency; on the FDA’s FAQ page, a vague answer maintains there are “many factors in deciding whether or not to initiate an enforcement action.” The Department of Agriculture handles research grants and pilot programs for hemp, but that’s where its involvement ends.
As mentioned above, cannabis and hemp differ in the levels of naturally occurring THC that they contain. THC is a cannabinoid like CBD. However, its properties are very different and often antagonistic to the effects of CBD. Hemp is naturally high in CBD and low in THC; the reverse is true of cannabis. In fact, hemp contains only about 0.3% – 1.5% THC, while cannabis contains about 5% – 10% or more THC.
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.
