CO2 extraction is one of the most common ways CBD is extracted from the hemp or cannabis plants. This method uses expensive equipment that adjusts temperature and pressure to extract the cannabinoids from the plant material, without damaging them. The other common method is to use solvents like ethanol or butane to extract the plant material. These solvents have to be burned off the final product which may damage the cannabinoids or terpenes in the process. There is also a risk that these solvents may not have burned off completely and could end up in your end product. 

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.  
“Acute CBD administration by the oral, inhalatory or intravenous route did not induce any significant toxic effect in humans. In addition, chronic administration of CBD for 30 days to healthy volunteers, at daily doses ranging from 10 to 400 mg, failed to induce any significant alteration in neurological, psychiatric or clinical exams. Finally, in patients suffering from Huntington’s disease, daily doses of CBD (700 mg) for 6 weeks did not induce any toxicity. Therefore, confirming results from animal studies, the available clinical data suggest that CBD can be safely administered over a wide dose range.“
Customer Service: It’s difficult to find contact information on Calm by Wellness’s website, and their email address is listed incorrectly in two places (we tried sending them an email but it was not delivered). We were, however, able to get a response through Facebook, and the company does offer free shipping and a generous 30-day return policy on all orders.
So when people began touting the benefits of CBD for pain, it was a big deal. A non-addictive substance that can ease pain without making you feel high or groggy? It’s easy to see why CBD has been making so many waves. In fact, cannabis plants have a long history as a pain reliever. Whether or not it’s true that Queen Victoria took CBD-rich cannabis to help with menstrual cramps, it is certainly true that her royal physician, Sir J. Russell Reynolds, listed cannabis as “one of the most valuable medicines we possess.” Victorian doctors aside, there are also ancient Assyrian and Ayurvedic manuscripts that recommend cannabis for pain.
Since it started becoming popular roughly two years or so ago, the general consensus has always been that since CBD oil from top brands does not contain the psychoactive properties of THC, it is therefore legal. Unfortunately, its legality is much more nuanced because of conflicting federal laws and new court cases. What is clear is that in one of the most recent court decisions on the topic, Hemp Industries Assoc. v. DEA, which came out on April 30, 2018, the US Court of Appeals for the Ninth Circuit found that Section 7606 of the 2014 US Farm Bill (the “Farm Bill”) preempts the Controlled Substances Act (CSA), the federal law which designates marijuana as a Schedule I substance (along with heroin and cocaine) making it illegal to possess or use. This means that when there is conflict between the CSA and the Farm Bill, the Farm Bill wins out.
This article provides a wealth of practical information for the individual considering CBD as an adjunctive or alternative treatment for pain and or anxiety. CBD works in the body by manipulating receptors throughout organ tissues, the immune system, the pain response system, the hormonal system, and other systemic regulatory systems. While CBD oils have not been reviewed or approved by the FDA for the treatment of these conditions, a wealth of literature, both anecdotal and research-related now exists to help describe both their safety and effectiveness. As discussed in this article, the potential new adopter must be mindful of several important items. First, only those products that are sourced from Industrial Hemp will be considered legal in all states. One must be careful if the product you choose is sourced from the marijuana plant, as those products may contain THC levels above the legal limit in your given state. Secondly, all products are NOT created equal – they differ significantly in strength, absorption, and elimination by the body and in the manner in which they are formulated. One should be mindful of the differences in doses available for each of these products, starting at a low or moderate dose and increasing as needed in order to find the lowest dose that provides the desired relief. In this way, one can individualize usage to maximize effectiveness, while minimizing risk, a proper goal for the use of all medicinals.

The science behind CBD is in the relatively early stages. As a cannabinoid, we know that CBD interacts with receptors in your endocannabinoid system. The endocannabinoid system is integrated throughout your body — and this widespread, whole-body interaction creates a broad range of effects. Hence, the long list of possible benefits.   We may still be in the early stages of discovery, but there’s plenty of scientific studies and anecdotal evidence that CBD provides relief for an array of ailments. Here’s a non-exhaustive list of some potential benefits of CBD oil:


However, if it was sourced from actual marijuana (i.e. cannabis that contains more than 2% THC by volume), then it is technically illegal. Most of the best CBD oils for pain that you find in dispensaries in states like Colorado, California, and Washington (as well as other states where weed is legal) will have been extracted from marijuana plants — not industrial hemp plants. Unfortunately, this means that these products are not allowed to be sold online and shipped across state lines to “non-legal” states.

Find the right CBD to THC ratio for you. Some people enjoy the high that THC provides, while others feel undesirably “out of it” when they use products with significant amounts of THC. No single ratio works for everyone, so experiment with a few different ones until you feel that the product you’re using is working well and helping you. You can also choose a ratio based on what you’re hoping to achieve with the use of CBD oil.[7]
A newcomer to our CBD oils ranking, RE: Botanicals is no stranger to hemp. Founded by John Roulac, a long-time hemp advocate and founder of the organic superfoods brand Nutiva, RE: Botanicals is one of the only CBD brands to earn the USDA organic seal. They deserve a shout-out for prioritizing regenerative agriculture, while keeping prices reasonable.   
Transparency: Receptra Naturals’ website has a database where you can look up lab reports for their products. The first time we checked, we got some 404 errors for a couple of the lab reports, but these glitches seem to have been fixed since then. We were able to see third-party lab reports for all their tinctures (though, apparently not for their topicals). 
It’s vital to know how and where hemp was grown. That’s because hemp is a bioaccumulator, meaning hemp absorbs contaminants from the soil while it grows. So if the soil it was grown on is not good, clean soil, then that plant might contain high levels of lead or mercury. When hemp is imported, it’s harder to ensure the hemp is grown responsibly, sustainably and without adding potential toxins to the products made from the crop. While it used to be that most CBD brands imported their hemp, today more and more brands use domestically grown hemp. We’ve also included some brands that use responsibly grown hemp imported from Europe.
After rubbing the oil and then the cream into the areas of spasticity that were painful enough to keep me in tears and awake night after night, the pain stopped and I fell asleep. I slept a full 10 hours, which hasn’t been possible in years. The next day I felt great. The second night I used it again and slept well again. However, felt tired, fatigued, and light headed.

Consume CBD oil if you want to quit smoking cigarettes. While consuming CBD oil, people sometimes report craving nicotine less. Withdrawal symptoms like anxiety and mood swings also aren’t as severe for many people when they take CBD oil. If you’re struggling to quit smoking cigarettes, try using CBD oil to potentially diminish your cravings and withdrawal symptoms.[13]
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.
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.
I was scanning reviews to see if anyone else had my experience. I purchased and tried a full spectrum CBD oil called Zilis ultra Cell. I researched after purchase and found it was a pyramid system product. Which usually offer great products, but pricey because of their system. I found that my asthma after the 1st day, was not as acute and less wheesie. However, I also took a dropper full at night twice. Both times my body was hot flashing, full body sweat- waking me up at night. My bowel movements changed to diarrhea with a spot of blood for two days. My health issue is always my lungs. Lately antibiotic help was temporary. So I thought I’d try CBD. After more research, I may have exposed that my lung issue may stem from colon issues. Worse case for me at this moment as this happened in this past week,…I may be first stages of colon cancer. This was a healing crisis, I am better every day. My next step is to do a colon test to be sure and to proceed with healing. Not afraid, just concerned and pro-active.
Because I never go downtown, I had to stop for a latte at my favorite coffee shop—and a second CBD pick-me-up. By the time I stepped into the crowded Indie Beauty Expo, I felt calm and happy. As an introvert, I usually have a hard time making small talk at events. But post-CBD oil, I felt comfortable enough to chat up a storm with every person I met! Three hours later I dragged myself out of the huge exposition and made it to my meditation class, where I took another dropper of CBD oil. Although I really love meditating, I find it particularly challenging to get into the “zone” after a long day at work. Not so much after taking some CBD—it was easy to calm my mind and tune into my breath, despite how fast-paced my day had been.
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]

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.  
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.
Honestly, I began to wonder if I was just experiencing the placebo effect. But on the one day, I didn’t take my CBD oil, I ended up picking a fight with my boyfriend (totally my fault) and let a few off-color remarks by a family member mess with my mood. Truly, I feel like it was a bit less anxious, both of those incidents could have been diverted.

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!

Vape Pens – Perhaps the easiest way to get the CBD Oil into your body is through a vape pen. A vape pen is about the size of an ink pen but has a CBD oil cartridge with a heating element. Many people like vape pens because there is very little in the way of odor after using it and it allows for a lot of discretion because it can be pulled out of your pocket and used on demand.

Cannabidiol is a chemical in the Cannabis sativa plant, also known as marijuana or hemp. Over 80 chemicals, known as cannabinoids, have been identified in the Cannabis sativa plant. While delta-9-tetrahydrocannabinol (THC) is the major active ingredient in marijuana, cannabidiol is also obtained from hemp, which contains only very small amounts of THC.  

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.
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.
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.

On the hemp side of the equation, the 2014 Farm Bill which legalized the growth and sales of agricultural hemp in the U.S., and the production of its derivatives like CBD oil, should help to open the way for research into the benefits and possibilities of hemp in all its forms. While we’ll summarize some of what we’ve found from our research into CBD side effects below, we expect to see a lot more research in this field in the years to come.

Seizure disorder (epilepsy). A specific cannabidiol product (Epidiolex, GW Pharmaceuticals) has been shown to reduce seizures in adults and children with various conditions that are linked with seizures. This product is a prescription drug for treating seizures caused by Dravet syndrome or Lennox-Gastaut syndrome. It has also been shown to reduce seizures in people with tuberous sclerosis complex, Sturge-Weber syndrome, febrile infection-related epilepsy syndrome (FIRES), and specific genetic disorders that cause epileptic encephalopathy. But it's not approved for treating these other types of seizures.

Really interesting reading all of the comments. I started using hemp oil capsules about 5 weeks ago mainly to treat aches and pains. I feel though like i’ve been going slightly mad, this is virtually impossible for me to describe, although i’ve been extremely happy, jokey etc, like everyone in the world is my best friend, my mind though is not at all right, everywhere I’ve been including familiar places like my own home seem so different, I almost feel like I’m looking at myself from a distance, I wish I could explain it better but it’s impossible to do so. I’m just on another planet. I’ve had stomach problems and I’m really off food, I’ve always been a hungry guy but not at the moment. I’m sure this product is fantastic for most people but sadly it doesn’t seem to suit me, I took my last capsule this morning, it suddenly hit me that is was the hemp causing the change in me. I’ll see what happens in the next few days. best wishes to everyone, like I said, everyone is my best friend at the moment.


I am new to taking CBD oil. I am getting sever chest pain and stomach pains after taking. I am looking for knowledgeable accurate accountable info on where to get top quality CBD oil. I find it helps with my anger, anxiety and depression. I am hoping it will help with my muscle weakness and inflammation but I feel I will have to stop taking it becasue of the side effects. I am simply looking for exceptional quality and ingredients. I am currently using Canntrust product and its carrier is MCT oil I believe. I could really use some advice. I don’t want to go back to having to take steroids. Please help. (Also, I am in Ontario, Canada)
The price of the product does not reflect it’s quality. Unfortunately, in the world of supplements, there are many unscrupulous companies. Just because it’s priced in the upper tier does not mean it’s upper tier quality. Look for companies that have third party testing and good comments and reviews. After much wasted money, I have learned that lesson. I hate hearing that herbal remedies are useless from people who’ve tried them, but don’t realize it’s the company that put in useless ingredients. Also, to the posters who report itchy mouth or other itchy side effects, my daughter is allergic to soy, even in trace amounts, her tongue, throat and the roof of her mouth start itching immediately and then her skin starts itching a few minutes later. I’m thinking that perhaps you are reacting to a soy oil carrier, or ingredient in the CBD, and not to the CBD itself. Perhaps a change to an olive oil carrier, or another type of product without soy, or lecithin.
We do not endorse or promote any particular brand because there is no one brand that is "best" for everyone. We do maintain a list of reputable brands to help narrow down the choices for those looking for recommendations. All of the companies on our best CBD oil brands list and expanded list of recommended brands have been vetted for product quality, customer service and positive feedback from users.
Fill the dropper with the CBD oil, place the tip of the dropper under the tongue and drip in the desired amount. Let the CBD oil get adsorbed for 1-5 minutes before swallowing it. If you are having a hard time with the dosage or the number of drops when you drip it under your tongue, you can also use a spoon. Just put the desired amount of CBD oil on the spoon and try to put it under the tongue. Just lick off the remaining oil on the spoon. Due to the fine blood vessels and mucous membranes in the mouth, the CBD quickly enters the bloodstream and therefore has a good bioavailability.

Everything you need to know about marijuana (cannabis) Marijuana, or cannabis, is the most commonly used illicit drug in the world. It alters the mood and affects nearly every organ in the body. With at least 120 active compounds, marijuana may have health benefits as well as risks. We describe these, addiction, and withdrawal. Learn more about cannabis here. Read now
All of the product reviews listed on this website are real reviews from real users. Recommended brands are selected solely based on merit. Our vetting process includes analysis of product quality based on third party lab reports, customer service quality and responsiveness, industry reputation, company longevity and customer feedback.

Any references to third party products, prices or websites referenced in this group are subject to change without notice. 

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.
