Success stories like Oliver’s are everywhere, but there’s not a lot of data to back up those results. That’s because CBD comes from cannabis and, like nearly all other parts of the plant, is categorized by the Drug Enforcement Agency (DEA) as a Schedule 1 drug—the most restrictive classification. (Others on that list: heroin, Ecstasy, and peyote.) This classification, which cannabis advocates have tried for years to change, keeps cannabis-derived products, including CBD, from being properly studied in the U.S.
But even though it's infiltrating pretty much every corner of the wellness world (hi, vegan CBD brownies!) many people still find CBD a little confusing—especially when it comes to figuring out the right way to use it and how to make sure the stuff you're buying is, you know, actually legit. Below, we asked experts to answer the most pressing questions about CBD.
There’s no definite amount that’s appropriate for everyone, but the ratio of CBD to THC will indicate how psychoactive the product is and if it’s legal in your state. The more CBD compared with THC, the less of a high, and vice versa. “Managing psychoactivity is key to successful cannabis therapy,” says Lee. “Amounts should be made clear on the label and lab-certified so people know what’s helping them and what’s not.”
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.
All of NuLeaf’s hemp plants are grown on licensed farms in Colorado using sustainable and 100% organic farming practices. Nuleaf’s CBD oils are made using whole plant extraction. That means the final product is a full-spectrum rather than CBD isolate. Moreover, NuLeaf doesn’t include any additives like preservatives, emulsifiers, or even flavors so the final product remains in its purest form.
In 2016 Louisville, Colorado-based Bluebird Botanicals was selected as the leading CBD oil company in the U.S. at that year’s Cannabist Awards, and that accolade came only four years after the business’ founding. In that time, though, Bluebird Botanicals has, according to cannabis industry market researchers Brightfield Group, grown to become the third-biggest selling producer of its kind in America. Perhaps that’s down in part to the stringent quality control measures that Bluebird Botanicals maintains – the results of which can be seen when looking at the certificates of analysis for each batch on its website. And the company’s “assistance programs,” created to aid disabled people, veterans and those on low incomes, also speak to an altruistic approach to customer care. People eligible can receive discounts on Bluebird’s classic and signature hemp extracts, vape oil and CBD isolate.
You won’t have to worry about potency with Spruce CBD. That’s because the potency of Spruce’s CBD oils are verified by a third-party testing lab. Spruce carries both regular and high potency CBD oil formulations. Spruce’s regular potency CBD oil contains a moderate dose of 25 mg of CBD per serving while their max potency formulation packs a strong dose of 80 mg of CBD per serving.
Although CBD oils aren’t regulated by the FDA, purchasing products stateside from one of the nine states where recreational and medical cannabis use is legal will likely result in a higher-quality product than buying one made with hemp-derived CBD oil imported from abroad, says Martin Lee, director of Project CBD, a nonprofit that promotes medical research into CBD.
The tincture is available in three strengths: 500mg, 1,000mg, and 3,000mg. Prices range from $0.04 to $0.07 per mg, depending on the concentration, which makes the tincture very low-priced compared to oils from most competing brands. Medterra also offers a 30-day satisfaction guarantee and will issue full refunds for all returns. In addition to the tincture, Medterra also offers CBD capsules in 25mg and 50mg concentrations.
First, a little background. Industrial hemp was legal in the United States until Congress passed the Marihuana Tax Act in 1937. ("Some of our early presidents grew hemp," notes Sarah Lee Gossett Parrish, a cannabis industry attorney based in Oklahoma.) Nearly 80 years later, the 2014 Farm Bill took the position that states can regulate the production of hemp and, as a result, CBD. Then last year, President Trump signed a new Farm Bill that made it federally legal to grow hemp.
CBD American Shaman’s extensive array of products ought to satisfy even the pickiest customer, ranging as it does from flavored tinctures to CBD-infused under-eye serum – and even, for horse lovers, an “equine ointment.” Furthermore, its inventive, water-soluble hemp oil supplement means that users can get their daily dose of CBD just by quenching their thirst. They’re all ways through which CBD American Shaman, as the website states, aims to “[bring] wellness to the world.” The company has a philanthropic streak, too, with a pledge that it frequently gives to non-profit organizations, while its “Compassionate Care” scheme cuts the prices of its goods for those with long-term health conditions. Plus, the company asserts that it uses only organic, non-genetically modified hemp in the making of its CBD oil products, with no insecticides used in the growing process.
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.)
The interest and preference for botanical remedies such as CBD oil over harsh pharmaceuticals are growing rapidly. You can read scientific research on the promise of CBD Oil at NCBI. While North America is taking the lead legalizing cannabis and hemp the rest of the world is starting to question their stance on prohibition because of the undeniable benefits. While all talk about plant-based remedies may seem very new, using cannabis/hemp tinctures as a holistic remedy is a generations-old tradition. It was very common to use cbd tinctures of cannabis oil in the eighteenth and nineteenth centuries. We are enjoying a renaissance in ancestral health where we are open again to remedies that were all but forgotten about in the mad race to make medicines a pill offered by a faceless often unaccountable corporation.
Chronic Pain: The body’s ECS plays a role in alleviating and managing pain, so CBD oil can work as a supplement for individuals with medical conditions that cause chronic pain, such as arthritis and multiple sclerosis. CBD oil also increases levels of adenosine in the brain; adenosine is a neurotransmitter that aids cardiovascular function and eases painful inflammation.
High potency CBD oils are ideal for those seeking a powerful, therapeutic effect. However, many companies only offer CBD oil in low to moderate potencies. Our pick for the highest potency CBD oil is Sabaidee’s Mega Good Vibes 2500mg+ CBD oil. At 88.33mg of CBD per serving, this is one of the most potent CBD oils on the market. And at $0.08 per mg of CBD, it is also reasonably priced. One 30mL bottle packs 2,500 mg of high-quality, full-spectrum, peppermint-flavored CBD oil.
CBD oil fans who switch between vaping and sublingual use are ably catered for by CBD Drip. That’s because the company sells an innovative range of full-spectrum oils that can not only be mixed with regular e-liquids or vaped by themselves but which may also be added to food and drink or simply applied under the tongue. For individuals who’d rather make up their own CBD oil-infused products, meanwhile, the company even offers concentrate in bulk. And CBD Drip assures its customers as to the purity and efficacy of its merchandise by explaining in detail on the website what is tested for and why; full lab results for many of its goods are also available to view at a click.
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.
NuLeaf only offers one concentration of CBD oil, 50 mg/ml, and the ingredients are as simple as it gets: USDA Certified organic hemp oil and full spectrum hemp extract. NuLeaf essentially has only one product. But this strategy allows them to keep their prices reasonable and offer bulk buying options—you can buy a bottle of NuLeaf CBD oil containing 240 mg total CBD all the way up to 4,850 mg.

CBD oil products needn’t be expensive, as Canabidol proves. The company’s pure cannabis oil drops, for example, sell from $28 for 10 ml, making them an affordable choice for new users still unsure about what CBD could do for them. That’s not to say that Canabidol’s goods aren’t up to scratch, though, as the business aims to ensure their quality through both its own bespoke method of analysis and by sending its oil to third-party labs. Among the products on offer, meanwhile, are innovative CBD Gel-Tabs, which feature a specially developed slow-release system designed to improve the body’s absorption of the active ingredient. And this, Canabidol claims, is “now the best-selling CBD cannabis oil product in the U.K.”

Most products labeled “hemp oil” do not contain any CBD. Those are typically hemp seed oil which is more commonly used for cooking or to make salad dressing. If you want to buy CBD oil, you’ll want to look for products that are labeled “CBD oil” or “hemp extract.” To confirm that a product you’re interested in has CBD in it, you’ll want to look at their third-party lab reports. All reputable companies selling CBD oil products will make third-party lab reports available to you to confirm the presence of CBD.
The vast majority of CBD oils come in bottles measuring either 15 milliliters (mL), or 0.5 ounces; or 30 mL, or 1 ounce. However, CBD concentration is more important than bottle size. Concentration refers to the ratio of hemp oil solution (measured in mL) compared to the amount of CBD cannabinoid (measured in milligrams, or mg). A 15-mL bottle may contain 100 mg of CBD, 300 mg, 500 mg, or more. The higher the mg amount, the stronger the CBD oil will be. For this reason, the ‘mg’ measurement is also referred to as the oil’s strength; i.e., 400-mg oil might be called 400-strength oil.
Fab has rapidly become the leading “lifestyle” brand in the industry. They are very engaged with their customers in their online community, and they have the top customer loyalty program that we’ve seen. Their full spectrum CBD oil drops and topical cream are made from 100% organically grown Colorado hemp, producing a very high-quality product. And their zero THC gummies get high marks from customers for taste and effectiveness.
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.
That leaves those touting CBD’s effectiveness pointing primarily to research in mice and petri dishes. There, CBD (sometimes combined with small amounts of THC) has shown promise for helping pain, neurological conditions like anxiety and PTSD, and the immune system—and therefore potentially arthritis, diabetes, multiple sclerosis, cancer, and more.
Third-Party Testing: Once a CBD oil is manufactured, CBD oil companies will often submit their products for third-party tests, which are conducted by non-company personnel to ensure the product is safe for public consumption and meets quality standards.CBD oils should always be accompanied with information about third-party tests; best practice is to avoid oils that do not supply these details.
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.)
The tricky part is that there's some evidence suggesting CBD works best for pain when combined with a little THC, says Dr. Danesh. "Depending on what type of pain you have, you might be able to do just CBD, but sometimes you need CBD and THC." This makes accessing a product that will actually help you more difficult due to different regulations in each state. In New York, where Dr. Danesh practices, for example, CBD is available over the counter. But as soon as you add THC, you need a prescription. 

Several weeks after a hysterectomy last spring, Bo Roth was suffering from exhaustion and pain that kept her on the couch much of the day. The 58-year-old Seattle speech coach didn’t want to take opioid pain-killers, but Tylenol wasn’t helping enough. Roth was intrigued when women in her online chat group enthused about a cannabis-derived oil called cannabidiol (CBD) that they said relieved pain without making them high. So Roth, who hadn’t smoked weed since college but lived in a state where cannabis was legal, walked into a dispensary and bought a CBD tincture.
When I went into the CBD American Shaman store, the manager seemed extremely knowledgeable, was certified, spent quite a bit of time explaining the different aspects of their products. I bought the full spectrum VG Cloud Tincture in strawberry banana and the 250 Topical Cream, which he said I would be amazed how well it worked. Hmmm. Maybe not so much, at least not yet. And the oil hasn’t helped as much as I hoped. Because they have a “Compassionate Care” program for those with disabilities, I was hoping this would be the one. Most of our family suffers from chronic pain and has had to go on disability, much to their chagrin. The products are $59.95 each, and the discount would be something like 30 per cent.

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.


Drum roooollllllll I received product and applied to my neck/ shoulder area, low back and hip areas (a dab spreads a big area) and within 15 minutes I was feeling relief and it lasted for about 6 hours!! And it keeps getting better as I learn from my body. Ending of a long story… CBD is now my go to relief and I’ve cut my oxycodone use by two-thirds already! Praise all around! Excited to continue on this journey and experimentation with education to find my sweet spot! Thanks again for this outstanding website!!
Unflavored hemp oil has a strong grassy and earthy taste. Some people enjoy the taste of natural hemp, but it’s not particularly popular. If a shot of wheatgrass sounds like a terrible idea, you’ll probably want to gravitate toward something with a more…palatable flavor. If you’re not sure, you can always start with a simple flavor you know you’ll enjoy, like mint or lemon, and get more adventurous over time.
Through its regularly updated and highly informative blog, Koi CBD goes the extra mile to help its customers learn about new developments in the field of CBD use. The company also helps its patrons out by publishing full lab results on each of its products, helping CBD oil users know exactly what to expect. And those purchases may include Koi’s bespoke full-spectrum CBD oil blend, complete with fellow cannabinoids CBDV, CBN and CBG – the inclusion of which, the company claims, “provide[s] the ultimate experience in CBD.” Also available to buy from Koi’s website are a range of 1,000 mg vaping liquids, lavender-scented body lotion, tropical-flavored gummies and, for canine CBD lovers, chewable treats.

Fab CBD offers an extensive line of deliciously flavored full-spectrum CBD oils in a broad range of potencies. You can choose between citrus, vanilla, mint, berry, and natural flavors and potencies of 5 mg, 10 mg, 20 mg, 40 mg, or 80 mg of CBD per serving. And like all of our favorite CBD brands, Fab CBD uses minimal ingredients with no additives—just hemp extract, coconut oil, and natural flavors.
We suggest using our dosage calculator to find the right dose or amount of CBD for your needs. If you are looking for relief for a specific issue, for example, back pain we suggest starting with our CBD Quiz to find the right product for you needs. Also if a organic or Non-GMO product is important for you look for that on the label or in the product description. Lastly, understand if you would prefer a full-spectrum cbd oil or a CBD isolate.  A full-spectrum oil contains many other beneficial parts of the hemp/cannabis plant while an isolate removes everything except CBD. Learn more about the difference here here.
Nearly every expert Health spoke to agreed that your CBD products should be tested by a third party to confirm the label's accuracy. This is a real concern in the industry—take the 2017 Journal of the American Medical Association study, for example, which tested 84 CBD products and found that 26% contained lower doses than stated on the bottle. Look for a quality assurance stamp or certificate of analysis from a third party (aka not the actual brand) or check the retailer's website if you don't see it on the product's label.

Real Scientific Hemp Oil touts itself as being somewhat of a pioneer, as – according to the company – its own variety of CBD oil was the first to hit the mainstream back in 2012. In addition, the brand claims that its RSHO-X CBD liquid is the earliest no-THC product of its kind, making it a sound choice for those worried about whether CBD oil use will influence the results of drug tests. The company is also transparent about the processes that go into making its varieties of CBD-containing hemp oils, helping customers make informed choices as to which of its products are best for them. And minds may be put at ease upon learning that Real Scientific Hemp Oil tests its CBD oil three times – a process which seems to speak to the quality, purity and safety of the provider’s wares.
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.
