What you gain from Full Spectrum CBD is called the “entourage effect.” Studies have suggested that CBD is most effective when it’s combined with other cannabinoids. Each cannabinoid has its own properties and confers its own benefits. Working together, a synergy is created that boosts the healing properties of CBD. Full spectrum CBD does, however, bring with it the sticky issue of THC. The government regulates concentration levels of THC at 0.3 percent, an amount which results in minimal psychoactivity.

CBD oil has numerous proven health benefits. Whether you’re looking to treat your anxiety, depression, chronic pain, insomnia, or just want to feel more focused and relaxed; then CBD oil (or gummies, dabs, or a pre-filled vape pen) is the perfect choice. They even make CBD dog treats so your furry friend can get the benefits. This CBD stuff is the real deal.


The main thing to consider when figuring out how to find the right strength CBD oil is to realize that everyone’s internal biochemistry is different – while your friend may be able to relieve her anxiety with just a single 3 mg dose, you may require several times that much in order to obtain the same results. Or, you may not find any relief at all. This is why it’s important to start off with the smallest possible dose, and work up from there.
Generally speaking, ingesting CBD oils using a dropper is typically the easiest way to stay in control of exactly how much you are taking. Plus, pure CBD oil will not contain additives that come with side effects. Remember, when you are using CBD oil or any kind of cannabis product, you must read the product label to determine the best dose for you.
Start with a small dose and work your way up. If you aren’t sure how much CBD oil to consume, start with just a few milligrams per dose and work your way up to a gram or more if you need to. CBD oil works best in small amounts and can have a reverse effect if too much is consumed, so it’s best to start off with a very small amount, experiment with a little more if necessary, and make adjustments until you’ve figure out what works best for you.[5]
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.
We’ve ranked every one of the high-strength CBD vape oils on this list according to a variety of attributes. We’ve graded them according to potency, quality, strength, flavor, shipping speed, customer service, and pricing; among other factors. Every one of the products on this list has been hand-selected by our editorial team. No matter which product you buy from this list, you can rest easy knowing that you’re buying one of the best high-concentration CBD oils on the planet today.
In your internet travels, you may also come across products called “terpsolates.” The manufacturers of these products infuse CBD Isolate with terpenes (but not cannabinoids like THC). These terpenes may enhance the effectiveness of CBD — or maybe they just make it smell good. This may be a good place to point out that not all CBD products are created equal. The industry is still largely unregulated, and the quality and quantity of CBD in a given product will vary wildly. Third-party testing definitely helps to monitor companies’ claims, but it’s still up to you as the consumer to do your homework on the best CBD products.
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.
A number of difficulties exist in evaluating published data on CBD or marijuana use for epilepsy. The extremely limited published studies were small, poorly described, and not well designed. Contributing to the difficulty of interpreting published studies, CBD products are not produced under the guidance of good manufacturing practices (GMP) and are not subject to regulations governing labeling, purity, and reliability. In other words, currently, there is no guarantee of consistency between products, or even differing lots produced by the same manufacturer. Without independent testing (e.g. USP certification) of CBD products for content and purity, as well as bioavailability testing of specific products, uncertainty surrounds the use of available CBD products in routine clinical settings.
Is CBD Legal? Marijuana-derived CBD products are illegal on the federal level, but are legal under some state laws. Hemp-derived CBD products (with less than 0.3 percent THC) are legal on the federal level, but are still illegal under some state laws. Check your state's laws and those of anywhere you travel. Keep in mind that nonprescription CBD products are not FDA-approved, and may be inaccurately labeled.
Buying online is less reliable still because there’s no regulation or standardization. What you see on the label may not be what you are getting. A 2017 study in JAMA found that of the 84 CBD products researchers bought online, 43 percent had more CBD than indicated, while 26 percent had less, and some had unexpected THC.“There’s a 75 percent chance of getting a product where the CBD is mislabeled,” says Marcu, one of the study’s coauthors.

CBD hemp oil has a huge range of potential health benefits and uses, including reducing pain, soothing anxiety, fighting chronic diseases, improving mood, eliminating depression, preventing inflammatory arthritis, protecting the immune system, balancing the metabolism, aiding sleep disorders, and healing the skin, among others. CBD oil can also be used in many different ways and has a variety of applications for natural health.
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).
To make matters more confusing, nine states (including California, Washington, and Colorado) let residents buy cannabis-based products with or without THC. Nearly two dozen other “medical marijuana states” allow the sale of cannabis, including capsules, tinctures, and other items containing CBD or THC, at licensed dispensaries to people whose doctors have certified that they have an approved condition (the list varies by state but includes chronic pain, PTSD, cancer, autism, Crohn’s disease, and multiple sclerosis). Sixteen more states legalized CBD for certain diseases.
Generalized pain, for instance, has dozens upon dozens of high profile research and clinical studies that have been carried out in universities and laboratories around the globe. One of the most well-publicized of these studies took place back in 2008, in which results determined that “cannabinoid analgesics (pain relievers) have generally been well tolerated in clinical trials … with acceptable adverse event profiles (meaning acceptable effectiveness for practical use).
CBD is suddenly everywhere — and it’s not hard to see why. It won’t get you high, has a good safety profile, and naturally treats dozens of conditions. But there’s a dizzying amount of choice out there, so we’ve ranked the 25 best CBD oils to help you get started. Whether you’re a rank beginner, or you’ve been experimenting with CBD for a while, we’ve got you covered.

Our bodies are thought to produce endocannabinoids by the billions every day. “We always thought the ‘runner’s high’ was due to the release of dopamine and endorphins. But now we know the euphoria is also from an endocannabinoid called anandamide,” its name derived from the Sanskrit word for bliss, says Joseph Maroon, MD, clinical professor and vice chairman of neurosurgery at the University of Pittsburgh Medical Center. We produce these natural chemicals all day, but they fade quickly because enzymes pop up to destroy them. That’s where CBD comes in: By blocking these enzymes, CBD allows the beneficial compounds to linger.
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.
Hemp oil does have a number of uses and is often marketed as a cooking oil or a product that is good for moisturizing the skin. It is also used in the production of certain soaps, shampoos, and foods. It is also a basic ingredient for bio-fuel and even a more sustainable form of plastic. Hemp has been cultivated and used for roughly 10,000 years, and it definitely has useful purposes. However, a lack of cannabinoids, namely CBD, means that it has little therapeutic value.
CBD works by attaching itself to specific receptors of the body’s own endocannabinoid system. The human body is known to produce cannabinoids of its own, which affect the cannabinoid receptors CB1 and CB2. The CB1 receptors are generally found in the brain, and deal with pain, mood and emotions, movement, appetite, among others. THC acts upon the CB1 receptors. Meanwhile, CB2 receptors are more commonly found throughout the immune system, affecting inflammation and thus pain. CBD is thought to act upon these receptors, by influencing the body to produce its own cannabinoids in order to rebalance itself.
While animal experimental data clearly suggest a potential benefit, supportive clinical data are quite sparse. In a case-control study of 308 cases of new onset seizures, Brust and colleagues found that marijuana use was significantly less prevalent among men who had unprovoked seizures compared to case controls (9). This difference was not significant in women. The authors suggest a potential protective effect against seizures with marijuana use; however, this should be considered speculative.

Tinctures – Typically tinctures are small glass or plastic “dropper” bottles that have cannabidiol oil mixed with a preserving solution such as alcohol. Tinctures were very a very common way to ingest botanical oils prior to the industrial revolution and are experiencing a resurgence in popularity as more people are looking for natural remedies. Tinctures with droppers allow you to put a few drops in your tea, under your tongue, or to bake the oil directly into your food.

Another major reason why CBD oil has been positively received in some parts of the medical community is its apparent effect on cancer and tumor growth.A study done by the researchers of the Institute of Toxicology and Pharmacology, University of Rostock, Germany recommends the use of CBD oil (even direct injection into tumors) to eliminate or reduce the size of the tumors. The antioxidants in CBD hemp oil also provide anti-mutagenic properties and lower users’ risk of cancer.
Transparency: Fab’s website features third-party lab results for most products. They only have a lab test for one of their tinctures though (which shows results for cannabinoid potency, as well as contaminants like pesticides). Customer service pointed out that the same CBD oil is used for all their products, but since potencies do vary, we appreciate companies that show potency testing for all products.

Read the label to find out the total milligrams of CBD in the entire bottle/product and how many milligrams are in one standard dose. CBD products vary in potency, with some containing more total CBD than others. Most products will have on the label exactly how much CBD is in one dropper or drop, so you’ll be able to tell exactly how much is in there.

It’s safe to say that Charlotte’s Web is probably the most recognized CBD brand out there — and it’s not all hype. This company pioneered the CBD industry and made it their mission to de-stigmatize CBD by setting the bar high for transparency. They produce and oversee their organic CBD products from seed to sale, standing behind them with a solid return policy.
