However, Bonn-Miller told Live Science that he thinks cannabis research is on the upswing. "If we flash forward five years I think you'll see more studies," he said. Those studies could reveal more conditions that CBD may be helpful for and may also reveal that some of the reasons why people say they use CBD oil are not supported by the science but are instead a placebo effect. "And that's why we need to do the studies," he said.
A report from the American Academy of Pediatrics (AAP) published in the journal Pediatrics cautions pregnant women and nursing mothers to avoid marijuana use due to possible adverse developmental effects to their baby. In a study reviewed for the report, short-term exposure to CBD was found to increase the permeability of the placental barrier, potentially placing the fetus at risk from certain substances.
Generally speaking, most marijuana producers and sellers (especially on the black market) don’t test for contaminants (metals, pesticides, bacteria, etc.). Rick Simpson Hemp Oil is actually more a method of extraction than it is a specific product. People use the Rick Simpson method with hundreds of different strains of marijuana, so the THC, CBD and other cannabinoid content of the final oil always vary greatly, depending on the cannabis the consumers are acquiring. Usually what’s used for Rick Simpson oil is a strain with an inferior CBD content (and high THC), because that’s what the vast amount of marijuana is nowadays.
However it’s classified, Cannabis ruderalis is naturally low in cannabinoids. Its real value lies in its genetics. While Cannabis indica and sativa flower based on how much light they get (the photoperiod), Cannabis ruderalis is what’s called an autoflowering strain. That means it reaches maturity—usually in 20 to 30 days—regardless of the light cycle.
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). According to the FDA, the 2018 farm bill “preserved the agency’s current authority to regulate products containing cannabis or cannabis-derived compounds,” though the agency has largely ignored CBD up until now. 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 agency plans to hold a public meeting and generally fact-gather “in the near future.” The Department of Agriculture handles research grants and pilot programs for hemp, but that’s where its involvement ends.
Unlike marijuana, hemp is legal in all 50 states according to state laws. The federal government, on the other hand, still recognizes the Controlled Substance Act of 1970, which defines agriculture, production, sale, and use of any type of cannabis as illegal — but it’s also not bothering people who purchase and use hemp CBD products. What’s more, the federal legal status of hemp will likely soon be changing.
It may have something to do with the fact that THC stimulates that CB1 receptor a lot, in turn triggering the psychoactive effects of marijuana like disturbed sensory perception, impaired motor skills, and anxiety. Conversely, CBD stimulates CB1 very lightly, causing some effects that seem downright opposed to those of THC including relief from anxiety, stress, and hyper-excitability.
Figuring out how much CBD oil to take can feel like trying to navigate through a complicated maze. The sheer volume of CBD brands on the market can create confusion for consumers, and when you take a closer look, it’s not difficult to understand why. Not only do vendors use different source materials (CBD-rich cannabis vs. industrial hemp, different strains, etc.), but they also implement different extraction techniques .
Cannabinoids are neuroprotective, meaning that they help maintain and regulate brain health. The effects appear to be related to several actions they have on the brain, including the removal of damaged cells and the improved efficiency of mitochondria. CBD and other antioxidant compounds in cannabis also work to reduce glutamate toxicity. Extra glutamate, which stimulates nerve cells in the brain to fire, causes cells to become over-stimulated, ultimately leading to cell damage or death. Thus, cannabinoids help protect brain cells from damage, keeping the organ healthy and functioning properly. CBD has also been shown to have an anti-inflammatory effect on the brain.
There seems to be a good amount of misunderstanding about how the passage of the Agriculture Improvement Act of 2018 (or the “2018 Farm Bill”) affects the legality of selling industrial hemp-derived CBD products. But to reiterate, nothing in the 2018 Farm Bill alters the FDA’s position on CBD pursuant to the Federal Food, Drug, and Cosmetic Act (FDCA). Here are some additional highlights from that statement:
Cannabinoids affect the transmission of pain signals from the affected region to the brain (ascending) and from the brain to the affected region (descending). A 2011 study showed that CBD and CBC stimulated descending pain-blocking pathways in the nervous system and caused analgesia by interacting with several target proteins involved in nociceptive control. Authors concluded that the cannabinoids “might represent useful therapeutic agents with multiple mechanisms of action.”  The following year, researchers reported that CBD significantly suppressed chronic inflammatory and neuropathic pain without causing apparent analgesic tolerance in animals.  And then in 2013, researchers concluded that chronic pain patients prescribed hydrocodone were less likely to take the painkiller if they used cannabis. 
Cannabinoids can be used along with opioid medications, and a number of studies have demonstrated that they can reduce the amount of opioids needed, lessen the buildup of tolerance, and reduce the severity of withdrawal. At least ten randomized, controlled trials on over one thousand patients have demonstrated efficacy of cannabinoids for neuropathic pain of various origins.
Choosing CBD products isn’t as simple as picking something off the dispensary shelf and then walking out the door. Consumers should be aware that a handful of hemp products on the market pay lip service to governmental regulations by labeling themselves as hemp, despite containing cannabinoids and terpenoids. Some CBD products are completely devoid of cannabinoids including CBD, despite package labeling. The FDA purchased a number of CBD products online in 2015 and 2016 to test them for the presence of CBD and other cannabinoids. They found that the amount of CBD these products claimed on their labels was markedly inaccurate; some didn’t even contain CBD.
Medterra is the only CBD brand I order from. I was a little skeptical about CBD at first but tried it on the advice of my doctor. I suffer from chronic pain and the only thing that helps the pain is this oil. It really helps with my back pain and I use the tincture and the new Cooling Cream. And the best part is that there are no side effects I dont feel drowsy or unfocused and it doesnt interact with other medications. And Medterra is a fantastic company. One time the shipping of my oil was delayed for some reason and they sent it using express shipping without an added cost Their service is great.
Our Hemp Classic CBD Oil extract contains 250+ mg cannabinoids per fluid ounce extracted from industrial hemp.

The cannabis oil is emulsified in organic hemp seed oil.
Our CBD oil is lab-tested as soon as it is extracted and then again by a third party lab (Steep Hill) in Berkeley, California, to ensure an accurate amount of CBD. In addition, we test for over 200 pesticides, herbicides, mold, fungi, heavy metals, and mycotoxins. We use cutting-edge testing and world-class equipment to ensure that our products are safe and healthy. Please contact us for current lab results.
CBD exists at the confluence of three huge consumer trends. The first is the herbal supplement boom, a $49 billion-a-year industry that has seen rapid expansion since about 2010. The second is the rise of the anxiety economy, in which all sorts of products, from fidget spinners to weighted blankets, are pitched as reducers of the mild panic of everyday life. And the third is the near-overnight creation of a legitimate cannabis industry, thanks to the spread of marijuana legalization.
Those warning letters aside, there’s not a lot of federal oversight right now over the claims being made or the products that are being sold. Cohen warned against buying CBD products online, because “there’s a lot of scams out there.” Yet his clinic sells CBD, and he admits, “I say ‘Don’t buy online,’ but ours is worth doing, because we know what we’re doing. We ship all over.”
For this study, 24 people with social anxiety disorder received either 600 milligrams (mg) of CBD or a placebo an hour and a half before performing a simulated public speaking test. Additionally, 12 other people with social anxiety disorder performed the same test without receiving any CBD treatment. Results revealed that pre-treatment with CBD significantly reduced anxiety, cognitive impairment, and discomfort while participants were delivering their speech.
