Some manufacturers ship CBD products nationally, an illegal action which the FDA has not enforced in 2018, with CBD remaining as the subject of an FDA investigational new drug evaluation and is not considered legal as a dietary supplement or food ingredient as of November 2018.[71] CBD is openly sold in head shops and health food stores in some states where such sales have not been explicitly legalized.[72][73]
Some U.S. state legislatures have passed “CBD only” (or, more accurately, “low THC”) laws, and other states are poised to follow suit. Some states restrict the sources of CBD-rich products and specify the diseases for which CBD can be accessed; others do not. Ostensibly these laws allow the use of CBD-infused oil derived from hemp or cannabis that measures less than 0.3 percent THC.

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.

CBD is showing real promise as a compound that can contribute to protecting the brain, thanks to its anti-oxidant and anti-inflammatory abilities. Scientists are investigating its role in neurogenesis and its ability to help the brain heal from injury, and as a treatment for neurodegenerative disease. Research suggests that CBD may help to reduce brain damage from stroke or other neurological injury. And CBD is increasingly looked to as a possible therapy for several neurodegenerative diseases, including Parkinson’s, Alzheimer’s, and multiple sclerosis.
In addition to positively affecting the endocannabinoid system, CBD has been the focus of more than 23,000 published studies about cannabinoids in relation to various medical indications including anxiety, epilepsy, inflammation, cancer and chronic pain to name few.

I tell several sellers of CBD food and drink what I learned from Blessing and ask what they think. “Return customers who come back, and swear by it and love it, buy two at a time to stock up for the week because they do find it to be very helpful,” says Tavares. Clancy echoes this: “We rely a lot on consumer feedback and testimonial, and generally it’s positive when taking that minimal amount. Now, that very well could be a placebo effect, but either way, people have come back and reported significant benefits when it comes to easing social anxiety.”
In the U.S., dietary supplements come with serving size suggestions located on the Supplement Facts label. We tend to encourage a “less is more” mentality when it comes to the amount of oils or capsules our customers consume on a regular basis. (We recommend starting out with 15 drops.) That being said, the serving size of our supplements is a matter of personal preference. We strongly encourage Bluebird customers to experiment with our products and consult with a healthcare professional as needed. This is the best way to identify the amount and frequency of consumption that works best for each individual.
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.
