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.
According to Ananda Hemp’s website, it’s something of a trailblazer in the CBD world, for it possesses what it maintains to be the U.S.’ first officially authorized hemp farm. Ananda Hemp also claims to be the earliest business to have legally imported its own hemp seeds – taken from what is said to be the most extensive privately owned cannabis seed bank in the world. This, the company says, “stands in contrast to many of [its] competitors, who are sourcing questionable, non-certified and untraceable CBD sources.” In any case, people who wish to see how Ananda Hemp’s process impacts on its products can see for themselves by using its full-spectrum extracts, softgels and topical salve. Those goods have themselves, it seems, been through the testing process a minimum of three times to ensure that their levels of potency live up to what’s written on the labels.
Employee-owned Lazarus Naturals touts its commitment to ethical business practices, including pricing that aims to enable anyone to sample its range. Indeed, for veterans and those with long-term disabilities, there’s even a commendable 40-percent discount on the company’s wares. Customers wanting more bang for their buck could, then, try Lazarus Naturals’ 3,000 mg flavorless CBD tincture, a 60 ml bottle of which costs $125, though an even more potent 6,000 mg tincture is also available. Plus, the supplier’s handy and inexpensive taster packs may be a boon for more indecisive or novice CBD oil users. These packs come in regular and high-potency varieties, both of which contain samples of the company’s tinctures, capsules and CBD-infused coconut oil.
Endoca’s commitment to social responsibility is such that it even has its own non-profit, The Endoca Foundation. This organization takes in the company’s Endoca Institute of Cannabis, Natural Medicine and Sustainability, which acts as a hub for education and research into medical cannabis; it also spearheads a hardship fund designated for those who wish to investigate the potential benefits of CBD oil products for themselves but lack the funds to do so. By purchasing Endoca products, then, as the producer claims on its website, “customers are not only helping to heal others but also the world.” Moreover, those customers can choose from Endoca’s array of skin care products and drops and even its variety of CBD oil chewing gum – all including oil from hemp plants cultivated using the company’s individual seed bank.

CBD capsules: These are gel capsules or tablets that you swallow like any other pill. People prefer capsules because dosing is precise (each pill contains a specific amount of CBD), they’re easy to travel with, and they’re easy to remember to take along with your daily vitamin. However, it does take longer to feel the effects of CBD with capsules (up to 90 minutes), since the capsule has to be processed by your digestive system first.
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.
If medical marijuana is illegal in a given state, THC levels determine whether a CBD product is illicit or not. In most places, the limit is extremely low. We’re talking under 1 percent THC, with some states opting for a cap as low as 0.3 percent. In this case, the only source that would work is hemp, and CBD products will, therefore, be hemp-derived.

The CBDistillery has two main strengths. The first is its variety of options. The CBDistillery offers CBD oil tinctures in a wide range of concentrations from 17mg up to 88 mg of CBD per serving. But what really sets the company apart is that they offer both full-spectrum and THC-free CBD oil options. Most people gravitate towards full-spectrum CBD oil to take advantage of the entourage effect. But with THC-free CBD oil, you can enjoy the benefits and effects of CBD even if you’re subject to mandatory drug testing.

“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.

Since 2014, NuLeaf Naturals – our Editor’s Pick – has been committed to creating high-quality CBD oil products. As one of the oldest and most reviewed companies in the industry, NuLeaf Naturals has established themselves as a trustworthy CBD manufacturer. All of their products are tested by third party labs and their cannabinoid profile is impressive. They offer a unique range of concentrations for their organic CBD products ranging from 240mg to 4,850mg.
To obtain the CBD-packed hemp extract from its organic crop, Highland Pharms uses a process called “supercritical CO2 extraction.” This method eliminates the need for more harmful solvents, while it also, the company says, yields CBD oil of an outstanding purity and efficacy. Those wanting to see for themselves can take their pick from Highland Pharms’ positively reviewed variety of tinctures – the strongest concentration of which measures up at 1,250 mg – as well as capsules and edibles. And if those potential customers have no idea exactly how much CBD they should be imbibing, then they can get themselves up to speed at the Texas-based company’s website, which offers a user-friendly guide to serving sizes and methods of CBD oil intake, among other common queries.
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.
Pioneers of the CBD industry, 4 Corners Cannabis helped pave the way for companies that want to provide quality products and utilize best practices. They grow their own strain of hemp and make small batches of true full-spectrum CBD products. Their prices place them lower down on our ranking, but their highly satisfied customers are more than willing to pay for the 4 Corners quality.  
Children: Like pregnant and breastfeeding women, clinical research among child-aged participants is less common. To date, much of the research of CBD with children has involved children with severe pediatric epilepsy. This research found CBD oil to be effective in symptom management, leading to the first FDA-approved drug containing CBD. However, the efficacy and safety of CBD for children has not been studied sufficiently to know if it has any long-term effects.
CBD oil products generally have a shelf life of at least one year, if stored in a cool, dark place. Refrigeration is typically not necessary as long as it is kept somewhere where the temperature is less than 77 degrees Fahrenheit. Tinctures that use MCT coconut oil as the carrier oil are known to have a longer shelf life than those with hemp seed oil as the carrier oil.
Vaporizers – Many state-licensed cannabis dispensaries offer high CBD strains of cannabis flower. This allows for reduced risk of paranoia while allowing for a high medicinal dose of CBD. Vaporizers are used to heat up the flower and remove the properties or compounds of the plant that you are looking for without combustion or smoking. Vaporizers use convection much like a convection oven. CLICK HERE to see our favorite vaporizer.
