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.  

Reviews may be few, but all on amazon are 4-star ratings and above. Currently, there are no negative reviews for this product. The majority of consumers state that they’ve experienced significant changes to pain levels as well as better management of arthritis pain. Most reviewers are very fond of the capsule intake method, which eliminates the need to measure oil dosages.


When administered alone, CBD is an effective anticonvulsant in maximal electrical shock (MES), magnesium-free, 4-aminopyridine, and audiogenic models (7, 8). Co-administration with AEDs leads to various effects; anticonvulsant effects of CBD are enhanced with phenytoin or phenobarbital but decreased with chlordiazepoxide, clonazepam, trimethadione, and ethosuximide. In a recent study using an acute pilocarpine model, although CBD administration reduced the number of animals displaying seizure activity, CBD did not appear to have any significant effect on the number of seizures per animal (7).
Of course, though, they offer less potent oils than that, with a product lineup that ranges from 300 mg CBD per bottle to 4,000 mg. Naturally the 4,000 mg option is the most expensive (this is the one that provides the “bomb” 60 mg dose), as it currently sells for $299. For long-term pain and anxiety relief, though, it may be well worth it if it is effective for you and helps replace your regular meds.
There are likely very complex relationships also occurring between various Cannabinoids in Cannabis that may lead to certain medical efficacy. That is important to remember when considering the consumption of products that contain Cannabinoids. There is an attractiveness to isolating a specific chemical, researching it, patenting synthetic derivatives, and marketing specific drugs. That said, the relationships are complex, will likely take years to understand, and many patients I’ve met appear to find the most medical benefit from a diverse group of Cannabinoids whose interactions are not particularly well understand, but the results are hard to argue with.

Unfortunately, due to strict FDA laws, I am not legally able to say that CBD will help with your specific condition, with that being said, you would need to buy the filled cartridges if you are using a pen that uses the screw on cartridges. Otherwise if you have a vape that has a tank on it you can buy our vape oil and do it that way. I hope this helps. Feel free to email [email protected]
This tincture is processed using the brand’s signature ‘Gold Formula,’ a full spectrum blend of terpenes, phytocannabinoids, fatty acids, and vitamin E. The drops are offered in three concentrations: 250mg in a 1-oz. container, or 750mg and 1,500mg in 2-oz. containers. Plus CBD Oil recommends taking half a dropper, or 15 drops, per dose. The drops are vegetarian-friendly and free of GMOs, gluten, and glycerin.

Roger, I’m not 100% certain on this, but I’m pretty confident that the difference here (and what makes it legal for people to sell it on Amazon) is that they are ONLY selling Hemp derived CBD vs. Cannabis derived CBD. Hence the “hemp extract” which is why the Farm Bill passing was such a big deal. As far as I’m aware, you can get CBD from both cannabis and hemp, but the hemp is legal federally. The bigger problem that I see is how misleading all of the amazon products are though because of these amazon regulations. All of the bottles I’ve seen only show the amount of “Hemp seed extract” (ex-2,500 mg Hemp Oil Extract) which is just like buying 2,500 mg of orange juice when I’m looking for vitamin c! 

It gets grown and manufactured in the United States of America. The hemp is Colorado certified, meaning it’s free from GMO, chemical fertilizers, pesticides, and herbicides. Safety and quality are top-notch, no need to worry. Full Spectrum Hemp Oil gets made from a premium formula that helps in reducing anxiety, improve sleep, soothes stiffness, decrease hormonal imbalances, eases the pain, support mood stabilization and weight loss, boosts metabolism, lowers inflammation, and relieves joint pain.
As illustrated above, it is a no-brainer; Canolane Organic Hemp Oil Drops 5000mg ranks high regarding quality and effectiveness. Thanks to the natural hemp oil used in its making and the many vital vitamins, Omega 3, and 6-9 fatty acids available. The oil sustains the overall wellbeing of the human body as it reduces pain, stress, and anxiety. Besides, Canolane Organic Hemp Oil Drops 5000mg is usually lab tested, guaranteeing of its quality and purity. Are you a vegetarian? Then this oil is meant for you as it gets made from 100% natural ingredients.

Weight plays a role in the effects of CBD oil, and bottle size should be selected based on how much you weigh. Let’s say you weigh less than 130 pounds and desire light CBD oil effects; this means that 11 mg or less will probably suffice per dose, giving roughly 40 doses from a 450-mg concentration. If you weigh more than 230 pounds and desire strong effects, then this same concentration will supply roughly 10 doses.

Extraction: The method by which CBD oil is processed from hemp plants can be very telling. Some manufacturers extract and process the oil using toxic materials like propane or butane; in most cases, these oils are cheaply priced. Safer extraction and processing agents include ethanol, which cleans the hemp plant of unwanted toxins; and supercritical carbon dioxide extraction, which strips harmful materials from the plant by changing the carbon dioxide’s temperature and pressure settings.
The important thing is that you have to be SUPER careful when selecting CBD oils. Since the cannabis industry is not FDA-regulated, there have been dozens and dozens of companies trying to get away with selling very low quality (and even potentially toxic), “snake oils” that have been extracted using harsh chemical solvents like butane and hexane. Make sure you stay away from cheap products like these, as they could damage your health.
Amazon’s Hemp Master 1000mg hemp seed oil is yet another highly concentrated oil, boasting a one-month supply in each bottle (30 ml). It’s made in the USA, with all-natural ingredients, including the peppermint extract used for flavoring. Each product is lab tested by FDA approved facilities for quality and strength and is completely THC free. As this product is derived only from hemp seeds and is not a full spectrum hemp oil, it does not contain CBD. However, it is packed full of Omega-3 and Omega-6, proven to assist in stress management, pain, and heart-related issues.
You can thin the CBD with terpenes, encapsulate it in dextrin, drive the terpenes off with heat, and use the now water-soluble CBD in water with an ultrasonic fogger/oil-diffuser. It won’t precipitate, but the level of solubility is pretty low even with encapsulation, think 100mg per 200ml. The evaporation rate of those units is somewhere like 50ml/hour, which works out to .83mg of CBD being vaporized a minute, or .14mg every 10 seconds. That’s a miniscule rate.
This is good news for the best CBD oil companies because the Farm Bill allows for the legal cultivation of industrial hemp, under certain circumstances, which can be a source of CBD. But CBD can also come from non-industrial hemp, namely the marijuana plant that most are more familiar with. Therefore, whether or not CBD oil for pain is legal can be a question of which “version” of the cannabis plant it was sourced from. If it was sourced from industrial hemp, (which contains less than 0.3% THC by volume), and it was cultivated under the Farm Bill, then it is legal.
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.

CBD may offer an option for treating different types of chronic pain. A study from the European Journal of Pain showed, using an animal model, CBD applied on the skin could help lower pain and inflammation due to arthritis. Another study demonstrated the mechanism by which CBD inhibits inflammatory and neuropathic pain, two of the most difficult types of chronic pain to treat. More study in humans is needed in this area to substantiate the claims of CBD proponents about pain control.
as long as it is ejuice (pg/vg) based then I’m sure using it in your tank or on your rda will work fine.. you may need new coils or atomizer cartridges after using it tho.. I’ve been vaping cbd juice in my rta like regular ejuice & it works just fine.. not rly sure about the effects.. maybe a little bit of a anti-inflammatory benefits & some anxiety/stress relief.. but i only just started vaping cbd’s & it’s supposed to take awhile for it to totally absorb your system for the effects to work optimally.. anyway.. if it helps you at all & can reduce your need for prescription drugs or other habit forming medications i say hi for it.. I’ve already quit smoking cigarettes by switching to vaping hopefully this will help me reduce another detriment to my health by not needing as much pain & anxiety medication
