There are likely very complex relationships also occurring between various Cannabinoids in Cannabis that may lead to certain medical efficacy. That is important to remember when considering the consumption of products that contain Cannabinoids. There is an attractiveness to isolating a specific chemical, researching it, patenting synthetic derivatives, and marketing specific drugs. That said, the relationships are complex, will likely take years to understand, and many patients I’ve met appear to find the most medical benefit from a diverse group of Cannabinoids whose interactions are not particularly well understand, but the results are hard to argue with.

Vape oil: CBD vape oil is used for vaping CBD. This requires the use of an e-cigarette or vape pen, which can have side effects when chemicals are heated to high temperatures. There are also CBD waxes available that are used for dabbing the cannabis compound. This also requires heating a small amount of the wax and using a dabbing pen. This isn’t recommended for beginners, as it’s usually a higher concentration of CBD.
Side effects of CBD include nausea, fatigue and irritability. CBD can increase the level in your blood of the blood thinner coumadin, and it can raise levels of certain other medications in your blood by the exact same mechanism that grapefruit juice does. A significant safety concern with CBD is that it is primarily marketed and sold as a supplement, not a medication. Currently, the FDA does not regulate the safety and purity of dietary supplements. So you cannot know for sure that the product you buy has active ingredients at the dose listed on the label. In addition, the product may contain other (unknown) elements. We also don’t know the most effective therapeutic dose of CBD for any particular medical condition.

“Buying from a reputable manufacturer is crucial, because it matters how the plant is cultivated and processed,” Dr. Maroon says. One clue that a company is cutting corners: too low a cost. Good CBD is pricey—a bottle of high-quality capsules is sold in Cohen’s office for $140. But for many, it’s worth the money. Roth spent $60 on her tiny bottle. But when her energy returned the day she started taking CBD, she decided that was a small price to pay.


The furry subjects, 277 Wistar rats, were given a dose of CBD immediately after receiving a small electric shock. The CBD-treated subjects were found to spend less time frozen in fear when reintroduced to the context of the fearful event. This means the CBD disrupted consolidation (or more simply put: memory strengthening) of their specific and long-term fear memory.
Other potential side effects include low blood pressure, lightheadedness, and drowsiness, but these have typically only occurred in patients who have exceeded doses of 1,500 mg daily for a period of 4 weeks or more; far more than the average person will need take on a daily basis for chronic pain symptoms. (In fact, the majority of CBD users claim they find an effective dose to be anywhere between 10 and 40 mg daily).
I stopped by Moon Juice after work, feeling a little nervous and excited all at once. “You might notice that your body feels a bit heavy after you try it—sometimes when I take it I feel like I just want to sit down and chill,” said the women behind the Moon Juice counter who helped me. Prepped for potential side effects, I emptied one dropper’s worth of CBD oil into my chamomile tea as soon as I got home … And didn’t feel anything. A few hours later I got into bed and immediately fell asleep.
CBD hemp oil is the product derived from the hemp plant, which is high in CBD (cannabidiol) and low in THC (tetrahydrocannabinol). This oil has received a large amount of attention in recent years, due to the growing wave of marijuana legislation and debate in many countries, including the United States. While cannabis and smoking marijuana (which often has a high level of the psychotropic compound THC) is still illegal in many places, as more is being learned about CBD, and its potential effects on health, it is becoming more and more accepted as a legal and safe remedy for a wide variety of health conditions. Since it has a minimal amount of the psychotropic compound THC, use of this oil does not result in a traditional “high”, so its effects are generally considered therapeutic, not mind-altering.
Where do you buy CBD oils? You may have noticed that CBD products are everywhere these days. You can easily find CBD oil and other products online and in certain health food/vitamin stores or spas. To separate the highest quality products from the rest, look for one that has a certificate of analysis, or COA. This means that the manufacturer tests the product for contaminants, and it meets lab standards.
At this time, there does seem to be a growing body of basic pharmacologic data suggesting there may be a role for CBD, especially in the treatment of refractory epilepsy. However, given the lack of well-controlled trials, we must also ask if we are getting ahead of ourselves. Clearly, this is an emotionally and politically charged issue. If this were any other uninvestigated pharmaceutical compound, would we feel as compelled to make the agent widely available before statistically valid class 1 evidence was available for review? Until data from well-designed clinical trials are available and reliable, and standardized CBD products that are produced using GMP are available, caution must be exercised in any consideration of using CBD for the treatment of epilepsy. In the meantime, based upon promising preliminary data, further clinical research should be wholeheartedly pursued.
Research on CBD and anxiety has generally looked at cannabis as a whole product, not as CBD as a standalone compound. Some studies suggest that it can help with anxiety: like this 2011 study that suggests CBDcan reduce social anxiety or this 2015 review that says CBD could be promising for many forms of anxiety. It’s also important to consider whether the CBD comes from the cannabis plant and therefore may include THC, a cannabinoid that for some, induces anxiety. Read our comprehensive article on CBD and anxiety, here.

High blood pressure is a globally ubiquitous issue. This study explores the connection between CBD and a reduction in blood pressure. It is particularly unique as it is noted that “there are no dedicated studies in humans to date, to our knowledge, looking at the effect of CBD on either resting cardiovascular measurement or on the responses to stress, with continuous monitoring of CV parameters.”

Take CBD oil to help treat your bowel disease. Some scientists claim that CBD and THC interact in a productive way with the bodily system that controls gut function. Because of this, people with bowel diseases, such as Crohn’s Disease, sometimes benefit from using CBD oil. If you have a bowel disease, consider taking CBD oil. It may also alleviate some of your pain.[12]
Unfortunately due to the disappointing and down right inaccurate position of the federal government in classifying Cannabis as a schedule one drug, most research institutions risk federal funding if they conduct real research on Cannabis. This has dramatically limited the potential for real research by real scientists to be conducted. That research is critical to better understanding the multitude of therapeutic effects of the various chemical constituents found in Cannabis.
However, switching to CBD oil from a conventional medication is far from a random stab in the dark. In fact, there was a large scale (and very well-documented) survey carried out less than two years ago that looked at precisely what percentage of patients were able to “swap” their side effect-inducing meds for a 100% natural, cannabis-based therapy.
To be clear, there is no one specific test, scan, or anything else of the sort that you can do to determine whether or not you need CBD oil for pain. Also, since cannabis is not yet recognized by the FDA, you unfortunately can’t really go to your doctor either and have them recommend it; until marijuana is FDA-approved, it cannot be prescribed by physicians.
Using rigorous review methodology, Gloss and Vickery conclude that based on the low quality of the reports available, there is insufficient data available to draw any conclusions regarding the efficacy and or long-term safety of CBD in treating epilepsy (11). From the data available, it does appear that daily doses of 200 to 300 mg were safe in this small group of patients for a short period of time (14).
Some CBD manufacturers have come under government scrutiny for wild, indefensible claims, such that CBD is a cure-all for cancer, which it is not. We need more research but CBD may be prove to be an option for managing anxiety, insomnia, and chronic pain. Without sufficient high-quality evidence in human studies we can’t pinpoint effective doses, and because CBD is currently is mostly available as an unregulated supplement, it’s difficult to know exactly what you are getting. If you decide to try CBD, talk with your doctor — if for no other reason than to make sure it won’t affect other medications you are taking.
A natural plant extract, CBD (or cannabidiol) has made a huge stir in the health scene over the last decade. It’s not hard to find plentiful anecdotal evidence of its benefits — people are using CBD for pain relief, mood regulation, cancer prevention, even seizure reduction. But if you’re in pain, you’re probably looking for more than anecdotal evidence. We get it — and we’re here to help.
Of course, though, they offer less potent oils than that, with a product lineup that ranges from 300 mg CBD per bottle to 4,000 mg. Naturally the 4,000 mg option is the most expensive (this is the one that provides the “bomb” 60 mg dose), as it currently sells for $299. For long-term pain and anxiety relief, though, it may be well worth it if it is effective for you and helps replace your regular meds.
This study combats the notion that CBD causes a THC high by discussing the misinterpretations of prior studies on the subject. In fact, the researchers state that two particular prior studies “have caused much confusion and uncertainty whether oral cannabidiol (CBD) is safe and whether subjects who are treated with CBD run the risk of positive workplace tests [for THC].” 

Transparency: cbdMD seems to be going through a transition with their third-party testing practices. Until recently, they only released a lab report for the CBD concentrate they use for all their products, but would not show potency testing for individual products. That seems to be changing. Currently, the only lab report on the website is for their concentrate (and it’s over a year old). But if you contact customer service, they’ll send you a lab report for any product. 
Customer Service: We’ve always received fast, informative responses to our queries about products and practices, but there are definitely customers out there who have not. A quick perusal of reviews shows customers who had issues with unaddressed orders. It’s hard to know exactly what the problem is in these situations, but the company’s strict return policy (seven days for unopened products only) probably doesn’t help. It should be noted that the company has a solid base of very satisfied customers as well.
There are more than 80 cannabinoids found in cannabis plants, with THC being the primary one, followed by CBD. However, in the hemp plant, which is a different strain of the species Cannabis sativa, CBD is the main active ingredient, and THC is barely present, making its use and legality more widespread. The reason that CBD is such an effective form of support for human health is due to the body’s endogenous cannabinoid system. This regulatory structure of the body has millions of cannabinoid receptors in the brain and nervous system, which react not only to plant-derived cannabinoids (such as hemp and marijuana) but also to natural cannabinoids produced within our body. When hemp oil is used and processed by the body, it is effectively boosting the function of the endocannabinoid system, helping our body regulate itself in many different ways.

CBD has been touted for a wide variety of health issues, but the strongest scientific evidence is for its effectiveness in treating some of the cruelest childhood epilepsy syndromes, such as Dravet syndrome and Lennox-Gastaut syndrome (LGS), which typically don’t respond to antiseizure medications. In numerous studies, CBD was able to reduce the number of seizures, and in some cases it was able to stop them altogether. Videos of the effects of CBD on these children and their seizures are readily available on the Internet for viewing, and they are quite striking. Recently the FDA approved the first ever cannabis-derived medicine for these conditions, Epidiolex, which contains CBD.
In fact, not only will CBD not make you high, it has been proven to counteract the psychoactivity of THC. This property makes CBD highly useful as a medical treatment for a wide range of conditions. In terms of the CBD products you can buy, the amount of THC present varies from none at all in a pure CBD Isolate to a minimal amount (less than 0.3%) in a Full-Spectrum CBD product.
CBD is well tolerated in humans with doses up to 600 mg not resulting in psychotic symptoms (15). In the few small placebo-controlled studies performed, no significant CNS effects were noted. Oral CBD undergoes extensive first-pass metabolism via CYP3A4, with a bioavailability of 6%. Following single doses in humans, the half-life of CBD when taken orally is about 1 to 2 days.1 In vitro studies have shown that CBD is a potent inhibitor of multiple CYP isozymes, including CYP 2C and CYP3A (16, 17). Whether these in vitro observations are relevant at plasma concentrations likely to be seen in patients is unclear. In addition, given its metabolism via CYP3A4, clinical trials of CBD in patients receiving enzyme-inducing AEDs, such as carbamazepine or phenytoin, will require detailed pharmacokinetic studies.
Social media is blasting this one out lately, showing that different parents have been treating their children illegally (in states that are not classed as medical states) to help prevent their children from having seizures or deal with epilepsy. While there has been limited scientific evidence on the topic, 2016 was a major turning point for the plant as a major study was conducted by Orrin Devinsky, a neurologist at New York University Langone Medical Center, showing profound results.
Like we said, once you start using CBD oil more frequently and are able to gauge how much you need to find relief or therapy, then you can jump up to the more high-potency products as needed. For reference, doses will typically range anywhere from 5 mg to 100+ mg in a single day. And for epilepsy patients, they may take anywhere between 300 mg to an entire gram (1,000 mg) per dose — or more!
Tinctures: Tinctures are another popular way to use CBD, likely because you can easily gauge exactly how much cannabidiol you are ingesting, like CBD oil. A tincture is usually extracted with alcohol or another solvent. With a tincture, you use a dropper and place the drops in the mouth. Sometimes, manufacturers will use carrier oils, natural flavors or fatty oils in their tinctures.
But it also requires careful research before making a purchase. Because the cannabis plant readily absorbs pesticides, heavy metals and other chemicals that are in the soil and water, it’s so important that cannabis plants are frequently tested while they are growing. And it’s up to manufactures to test CBD products, too. When you are shopping for CBD oil, look for products that have been tested for contaminants and for CBD vs. THC levels.

This is the second time Moon Mother Hemp Company has placed among the top five brands on our ranking. The Colorado-based company, which was founded about a year ago, sets the bar very high for quality (including USDA-certified organic hemp) without charging the moon for its products. Their tinctures taste so good, you may be sad you don’t need more.
