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.
There are two main types of receptors in the ECS, CB1 and CB2. CB1 receptors are primarily located in the central nervous system and brains of mammals, and CB2 are generally found in the peripheral nervous system. There are two main cannabinoids mammals produce- 2AG and Anandamide (named after the Sanskrit term “Ananda,” which translates to “peace”).
A 2016 review of animal studies indicated that cannabidiol has potential as an anxiolytic for relief of anxiety-related disorders and fear. Reviews of preliminary research showed cannabidiol has potential for improving addictive disorders and drug dependence, although as of 2016, they indicated limited high-quality evidence for anti-addictive effects in people. A 2007 study on aggressive breast cancer cells demonstrated that cannabidiol was found to reduce the growth rate and invasiveness of breast cancer cells by acting to down-regulate Id-1 expression. 
Here’s what we do know: The cannabis plant contains a wide variety of chemical compounds, many of which fall under the broad category of cannabinoids. There are more than 100 — exactly how many, we’re not sure. The best-known and certainly most profitable are tetrahydrocannabinol (THC) and cannabidiol (CBD). Both of these compounds stimulate the same receptor in the brain, called CB1, but have differing effects on the brain. Researchers aren’t totally sure why.
One study found that placebos sometimes work even when the subject knows it’s a placebo. Another, using that same public speaking setup that CBD studies have used, found that anxiety treatments are particularly susceptible to the placebo effect, with 40 percent of placebo-treated patients showing a decrease in anxiety symptoms while tasked with speaking to a crowd.
