The endocannabinoid system is spread throughout your brain and body, but primarily throughout your central nervous system. The interaction between cannabinoids and receptors is what produces effects like the regulation of mood, pain, appetite, inflammation, and memory. Plant-based cannabinoids, found in cannabis plants, also interact with the receptors (whimsically named CB1 and CB2) in the endocannabinoid system, and each affects your body in different ways. CBD and its infamous cousin THC are the 2 most well-known cannabinoids.
All safe and reputable CBD brands make third-party lab reports readily available on their website or upon request. These reports detail the results of product testing by an accredited third-party laboratory that specializes in cannabis testing. They give you great insight into which cannabinoids and terpenes are in the product and whether it passed tests for heavy metals, pesticides, and other potentially dangerous ingredients.
Online Retailers: Most CBD oils are sold through online retailers. These establishments tend to have the widest product range, and many offer free doorstep delivery. Online retailers also frequently post product reviews, allowing buyers to compare different oils based on customer experiences to determine which is best for them. These reviews can also be used to evaluate the retailer based on customer service, delivery, and product quality.
In addition to an unflavored option, the drops also come in peppermint and goji berry flavors that are perfect for mixing with beverages. The nutritional information for all three flavors is found on the PlusCBD Oil website. The drops are fairly inexpensive, priced at $0.15 per mg or lower depending on the concentration. The brand offers fast shipping throughout the U.S. and to a wide range of international destinations.
Customer Service: There are multiple ways to get in touch with customer service, and Pure Hemp Botanicals’ customer service representatives are both quick to respond and forthcoming with information. On the down side, free shipping kicks in at $100 — otherwise it’s a pricey $9.99 flat rate. And you can return products, but only if they’re unopened.
Spruce was founded by Tony Spencer, who had a clear mission for his company—give people access to safe and effective lab-grade, hemp-based CBD. Spencer realized that many other CBD oils on the market were low-potency and simply didn’t work. “We have a lot of customers in pain who have wasted money on CBD products in the past that didn’t work for them,” remarks Spruce on their website.

People taking other medications: When side effects are reported, it’s often by this group. CBD appears to have a similar effect to grapefruit on the liver’s ability to metabolize certain drugs, which can lead to adverse side effects. Generally, if a medication has a grapefruit warning, you should avoid taking CBD. Although, if you are on any medication you should talk to your doctor before starting CBD, to ensure you won’t expect any negative interactions.
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. 

Dry Mouth: As is the case with many other hemp- and marijuana-based products, CBD oil often leads to a condition known as dry mouth (or cottonmouth). This is likely due to cannabinoids altering receptors in the lower jaw that trigger salivation. In most cases, mild discomfort and stronger-than-average thirst are the only issues associated with dry mouth.
As noted in the previous section, CBD oil prices vary significantly by brand. The best practice for most is to determine a per-milligram budget for CBD oil, as well as a maximum price for the entire bottle. For example, you might decide that 10 cents per milligram or less is a reasonable budget; and that $45 (for a 450-mg concentration, based on the budget) is a maximum bottle price. Also, if ordering online, be sure to include potential shipping costs.
Generally, CBD oil is made by combining an extract with a carrier fluid or oil. This question is best answered by looking at how the CBD oil was extracted. CBD oil can be extracted using CO2 systems or by using chemical solvents. Both methods produce a CBD oil byproduct that is then combined with a fluid like MCT oil, coconut oil, or olive oil so that it can be delivered to the body. Always check to make sure you know the CBD content of the products you purchase.
One of the easiest selections to grab a spot here on our “top 20 best CBD oils for 2019” is Florida’s very own Verified CBD. This company is what I would call part of the “old guard,” even though they’ve only been around since 2014 and are less than 5 years old. The main reason I like them is because they’ve made an effort to maintain a “seed to sale” operation, meaning their entire manufacturing process – from growing the raw hemp to bottling and selling the oils, takes place right here in the USA (no outsourcing or private labeling).
Research on CBD and anxiety has generally looked at cannabis as a whole product including THC, 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.
This is a confusing one for many people. "A lot of brands don't do a good job of clearly instructing their consumer on the dosing," says Chris Roth, CEO and co-founder of Highline Wellness. When thinking about dosing, also consider whether your CBD is full-spectrum or isolate: Full-spectrum could include other cannabinoids like cannabidivarin or cannabigerol (this is important, since "there's something called the 'entourage effect' when all together, they're more effective than any one of them alone," Roth explains), while isolate is 100% CBD. "Some people might only need 10 milligrams of full-spectrum CBD, but with isolate, even taking 80 or 100 milligrams might not have the same effect," he says.
Drops (also referred to as tinctures) are the most popular way to take CBD oil. They are typically sold in glass bottles with a built-in dropper. The drops are placed under your tongue and held there for at least 60 seconds. This drop process allows the CBD to absorb sublingually into your bloodstream. Other popular ways to take CBD include vaping, gummies, capsules, and topical creams. How you take it is a personal decision based on your preferences. Many experienced users take multiple different products at the same time. 

CBD Essence is another brand we’ve had plenty of experience with over the past 18 months or so, and my partner particularly likes his 600 mg Medicinal Grade tincture for quickly easing her anxiety. I haven’t tried them so much for may pain, but I do recall that a 30 mg dose was quite effective the last time I did take it. Also, the main reason they’re this high up on our list is because they’re a fair amount cheaper than Elixinol and PureKana. Their tinctures come in larger 2 oz bottles, but on a CBD-per-mg basis they’re about 20% less expensive than other top-quality brands.
Whether you are looking for CBD for general wellness or for specific medical conditions it’s important to look for these forms of lab test results; heavy metal testing, clinical trial information (if available), pesticide testing, microbial testing, potency testing, and cannabinoid profile. While having this information provided by a CBD company is important, it doesn’t necessarily mean their product will work for you. However you do not want to consider a CBD company that doesn’t provide the testing info mentioned above. Learn more about recommended best practices to look for here.
CBDistillery is our Editor’s Pick because of its diverse product line and commitment to high quality and customer service. They’ve earned a rating of 9.7/10 from our users who most often mention their product quality, effectiveness, great prices, and fast shipping times. Their most popular product is their 1000mg 30ml full spectrum CBD oil tincture. Priced at $60, it has 33mg of CBD per milliliter and is an excellent starting point for beginners. In addition to other full spectrum options, they also have zero THC drops for those looking for CBD oil without THC.
Dry Mouth: As is the case with many other hemp- and marijuana-based products, CBD oil often leads to a condition known as dry mouth (or cottonmouth). This is likely due to cannabinoids altering receptors in the lower jaw that trigger salivation. In most cases, mild discomfort and stronger-than-average thirst are the only issues associated with dry mouth.

Dispensaries: In states where marijuana is legal for recreational use, dispensaries are a common sight. They are much rarer in states with more restrictions. In states that permit the use of medical marijuana, hemp-based CBD oils do not normally require a prescription but marijuana-based oils do. Like brick-and-mortar locations, dispensaries offer more customer service. However, as noted, this may not be an option depending on the buyer’s state of residence. Also, CBD oil prices tend to be significantly higher at dispensaries.
That same 2018 Farm Bill means you can now travel between states with legit CBD products. "Flying with CBD should pose no issues now," Parrish says. However, if you're traveling with a tincture, be mindful of TSA limits on how much liquid you can carry on an airplane, she adds. (You can also mail CBD products, just like "companies that comply with the Bill can ship their hemp-derived CBD products anywhere in the U.S.," Parrish notes.)
REM Behavior Disorder: REM behavior disorder (RBD) is a parasomnia disorder characterized by shouting, becoming physically agitated, or otherwise acting out during sleep. For many, RBD is a symptom of a larger, more serious condition or disorder, such as Alzheimer’s disease or PTSD. CBD oil minimizes the symptoms of RBD, and also alleviates the anxiety and painful symptoms that often accompany disorders that lead to RBD.
