4 Corners Cannabis Review

4 Corners is a true “soil to oil” company — growing, harvesting, processing, and bottling all their own hemp extracts.

This brand has been around for a long time and has an impressive cult following to prove it. They’re clearly doing something right.

4 Corners Cannabis offers an extensive range of CBD products covering all major categories: topicals, oils, vapes, pet products, honey, and more. We especially like 4 Corners full-spectrum avocado oil.

We highly recommend this company if factors like organic hemp and grassroots extraction are important to you.

Mission / Charity 5/5

4 Corners is very clear about its mission to produce top-quality premium cannabis. They not only want to help people but also educate them about the healing benefits of hemp.

Hemp Source 5/5

4 Corners sources its hemp from its own organic farms located in Colorado. They cultivate a particular strain called Ma’at, which has CBD concentrations amounting to nearly 17%.

We love a CBD company that does all its own growing. This is the only way to know with 100% certainty what’s inside the products you’re selling.

Product Range 5/5

4 Corners offers several types of CBD products, including oils, tinctures, topicals, and vape liquids. They haven’t forgotten your furry pals — offering pet-centric tinctures with dog-friendly peanut-butter flavoring. 

Innovation 5/5

4 Corners uses ethanol derived from sugar cane that’s later used to extract high-quality, potent CBD. We have to give them some props for some of the early innovations this company had in the CBD space. Some of the stuff these guys were doing years ago are now commonplace in the CBD market.

They also offer some unique options for their CBD oils that we haven’t seen elsewhere — like avocado oil as the carrier oil or cinnamon flavorings.

Safety 4/5

4 Corners is very particular about their test reports. You will find the results of all tests conducted by a third-party laboratory called Aurum Labs.

Although they’ve tested for contaminants, potencies, terpenes, and microbes, we wish they would update it frequently. For example, the lab report for their salve is more than a year old.

Customer Service 5/5

This company has a responsive and knowledgeable customer service team. They accept returns within 30 days of purchase without the hassle and are reachable via email, telephone, and social media.

No complaints to 4 Corners for customer service.

About the Company: 4 Corners Cannabis

4 Corners is an old player in the CBD industry. Established in 2013, the company is backed by experts like Justin Jasiewicz and Brian Jasiewicz, with over a decade of experience cultivating premium cannabis.

Both founders focus on growing low-THC high-CBD hemp and oversee the production process to ensure strict standards. As the name suggests, 4 Corners does not cut corners when it comes to maintaining top quality. A dedicated team of experts manages the entire process from cultivation to extraction and packaging.

The founders believe in-house production offers more control over the quality of their products (and we tend to agree).

The company uses all-organic hemp to create its raw hemp extracts. As part of their strict quality control, any plants that aren’t up to snuff are composted back into the soil.

1. CBD Oils & Tinctures

CBD oils are made by mixing hemp extracts — full-spectrum, broad-spectrum, or isolate — with carrier oils like hemp seed, coconut, and MCT.

A) 4 Corners Coconut Citrus Oil Tincture

$17.49 – $99.99
4 Corners Cannabis

4 Corners Cannabis CBD Tinctures 15 – 30 mL

3.83 / 5

Total CBD : 250 – 2000 mg
Potency: 16.6 – 66.6 mg/mL
Cost per mg CBD : $0.05 – $0.07
Extract Type : Full-spectrum
Carrier Oil Options: MCT | Avocado | Vegetable Glycerine
THC Content: <0.3%

Made by infusing a full-spectrum hemp extract with MCT oil and limonene derived from oranges. It has an incredible uplifting quality to it from the rich citrus terpenes.

You can order this full-spectrum CBD oil in potencies from 250 mg per ounce up to 2000 mg per ounce.

B) 4 Corners Avocado Oil Tincture

This CBD tincture uses avocado oil as a base.

Avocado oil is light and has a nice creamy taste. This is the first product we’ve seen that uses this particular carrier oil as a base, and honestly love it. We’re surprised this is so uncommon. It’s nice and smooth, easy to take, and doesn’t really offer any downsides (excellent bioavailability, high solution rate, etc.).

Total CBD 250 – 2000 mg
Potency 16.6 – 66.6 mg/mL
Cost per mg CBD $0.05 – $0.07
Extract Type Full Spectrum
THC Content <0.3%

C) 4 Corners Cinnamon Tincture

The Cinnamon Tincture doesn’t contain a carrier oil. Instead, it’s made by combining glycerin with a full-spectrum hemp extract and other ingredients like cinnamon extracts and cane alcohol.

This tincture has a pleasant warming sensation — best for people who are using CBD oil during the day, to alleviate stomach pain or discomfort, or for chronic joint pain.

The warming action of cinnamon is a common herbal medicine for improving blood flow to the periphery — which carries fresh blood and nutrients along with it.

Total CBD 250 – 2000 mg
Potency 16.6 – 66.6 mg/mL
Cost per mg CBD $0.05 – $0.07
Extract Type Full Spectrum
THC Content <0.3%

D) 4 Corners THC-free Choco Mint Oral Tincture

If you’re uncomfortable with using products containing even trace amounts of THC, this THC-free tincture is tailored just for you. Crafted by mixing a broad-spectrum hemp extract completely free of THC with organic lecithin and MCT oil, this product tastes like chocolate, mint, and, of course, CBD.

Total CBD 1000 – 2000 mg
Potency 33.3 – 66.6 mg/mL
Cost per mg CBD $0.05 – $0.04
Extract Type Broad Spectrum
THC Content 0%

E) 4 Corners THC-free Coconut Citrus Oral Tincture

Coconut Citrus Oral tincture is another variation of the Choco Mint tincture. Made with a broad-spectrum extract, this product is also devoid of THC. The only difference is that it tastes more like oranges due to the inclusion of orange peel extracts.

Total CBD 1000 – 2000 mg
Potency 33.3 – 66.6 mg/mL
Cost per mg CBD $0.05 – $0.04
Extract Type Broad Spectrum
THC Content 0%

2. CBD Vapes

CBD vape oils are hands down the fastest way of feeling the effects of CBD. Just a few puffs of a decent high-potency vape oils, and you’re good to go for 3 or 4 hours.

The only downside to vapes is that they don’t last as long as a tincture or edible. You’ll need to redose every few hours.

4 Corners CBD Glycerin Tincture

4 Corners Cannabis glycerin tincture
$59.99 – $99.99
4 Corners Cannabis

4 Corners CBD Glycerin Tincture 30 mL

4 / 5

Total CBD: 1000 – 2000 mg
CBD Potency : 33.3 – 66.6 mg/mL
Cost per mg CBD: $0.04 – $0.05
Extract type: Full-spectrum
THC Content: <0.3%

4 Corner Glycerin tincture contains vegetable glycerin and a full-spectrum hemp extract along with hints of limonene derived from oranges.

This stuff has a really nice, smooth, citrusy vapor. It doesn’t produce the nice thick clouds we’re used to with some of the other vape oil options, but the absence of harsh chemicals in leu for more natural, plant-based ingredients is welcomed with open arms.

3. CBD Topicals

CBD topicals are usually meant to solve two problems — for personal skincare or for managing pain and inflammation. There are lots of topicals optimized for helping with conditions like psoriasis, eczema, or acne, and others optimized for joint pain or muscle pain.

For best results, you should opt for CBD topicals that have high concentrations of CBD (at least 4 mg/mL). All 4 Corners CBD topicals meet these criteria.

A) 4 Corners CBD Salve

$2.99 – $24.99
4 Corners Cannabis

4 Corners Cannabis CBD Salve 4.43 – 60 mL

4.33 / 5

Total CBD : 40 – 500 mg
Potency : 8.3 – 16.6 mg/mL
Cost per mg CBD : $0.05 – $0.07
Extract Type : Full-Spectrum
THC Content: <0.3%

This is 4 Corners’ all-purpose CBD salve — and it’s pretty great. It contains a blend of organic ingredients, including CBD, coconut oil, and beeswax. It contains an impressive concentration of CBD (8.3 mg/mL) which makes it useful for just about any topical application (muscles, joints, skin, etc.).

4 Corners also has another variation of the same product with the addition of menthol and vitamin E to give the salve a nice cooling sensation. This is perfect for use on sunburns or sore muscles.

B) 4 Corners CBD Salve Stick

This CBD salve stick has a thicker, waxier consistency than the original CBD salve and comes in a convenient deodorant stick-styled applicator. You can just run it over your sore or inflamed muscles or joints without having to get your hands covered in salve.

This stuff is nice and potent — containing up to 9 mg of CBD per mL of salve. That’s nearly double the average potency for CBD topicals these days.

Total CBD 40 – 80 mg
Potency 9 – 5.4 mg/mL
Cost per mg CBD $0.07 – $0.06
Extract Type Full Spectrum
THC Content <0.3%

C) 4 Corners Grape Seed + Jojoba Massage Oil

4 Corner Cannabi's Massage Oil
$24.99 – $39.99
4 Corners Cannabis

4 Corners Grape Seed + Jojoba Massage Oil 4 oz – 8 oz

4 / 5

Total CBD: 500 – 1000 mg
CBD Potency: 4.23 – 4.22 mg/mL
Cost per mg CBD: $0.03 – $0.04
Extract type: Full-spectrum
THC Content: <0.3%

Not many companies offer a CBD massage oil, so it’s a pleasant surprise that 4 Corners has a massage oil infused with the goodness of CBD and skin-loving oils like Jojoba and Grape Seed.

This oil has a really nice silky smooth consistency and delivers a decent dose of CBD to boot. With just over 4 mg per mL of CBD, this stuff works great for providing added pain relief to sore or tense muscles.

D) 4 Corners THC-Free CBD Salve

4 Corner’s THC-free CBD salve is very similar to its original CBD salve. The main difference is that this product is made from the company’s THC-free CBD isolate extract instead of the full-spectrum hemp extract.

Most research supports the idea that CBD works best in full-spectrum form, but there are some good reasons to avoid even trace amounts of THC, so 4 Corners is catering to all crowds with this topical THC-free salve.

To make up for the lack of efficacy when removing THC, 4 Corners doubled the potency of this salve for a grand total of 17 mg per mL! One of the strongest salves pound for pound we’ve seen yet.

E) 4 Corners CBD Lotion

Compared to the salves, 4 Corners CBD Lotion is silky smooth and has a fast absorption rate into the skin. If you want to use a topical but, don’t like having a waxy mess on your skin for up to an hour after applying, use a lotion instead.

Lotions don’t last quite as long as salves and aren’t as good for serious joint or muscle pain, but they’re effective for your average application and won’t leave residue on the surface of your skin.

This lotion contains a blend of full-spectrum hemp extract and several other natural ingredients like Aloe vera, Vitamin E, Beeswax, Vitamin C, and Coconut oil.

4. CBD Honey

CBD honey holds a special place in the world of CBD products. Honey has the unique ability to act as a solvent for cannabinoids. You use CBD honey the same way you would use a CBD tincture — hold it under the tongue, add it to drinks, or spread it over some toast — whatever you like.

4 Corners CBD Honey contains the company’s infamous full-spectrum hemp extract along with organic locally sourced honey. It’s dark, rich, and absolutely delicious.

5. CBD for Pets

Like humans, our beloved pets also suffer from various ailments. And, just like CBD can help humans by interacting with the cannabinoid receptors in the endocannabinoid system, it can also be beneficial to animals. So it’s no wonder that veterinarians also prescribe full-spectrum hemp products to dogs, cats, birds, horses, and many more.  

4 Corners has an extensive lineup of pet products compared to other brands. Most companies offer a generic CBD oil that usually contains CBD isolates combined with carrier oils; however, 4 Corners provides four types of pet CBD products to give you more options to help your pets. 

A) 4 Corners Pet Tincture 

4 Corners Cannabis Pet CBD Tincture
$12.49 – $69.99
4 Corners Cannabis

4 Corners Pet CBD Tincture 15 – 30 mL

4 / 5

Total CBD: 250 – 2000 mg
CBD Potency : 16 – 25 mg/mL
Cost per mg CBD: $0.03 – $0.04
Extract type: Full-spectrum
THC Content: 0%

Available in four different potencies ranging from 250 mg to 2000 mg, 4 Corners Pet Tincture allows you to start with small doses and increase them gradually. Although the 1000 mg and 2000 mg concentrations may smell potent and slightly bitter, this tincture could improve sleep and decrease anxiety. With minimal THC, this tincture is boosted with omega 3,6 fatty acids and MCT oil combined with organic hemp extracts. 

B) 4 Corners Peanut Butter CBD Tincture 

4 Corners Cannabis Pet CBD tincture
$39.99 – $69.99
4 Corners Cannabis

4 Corners Peanut Butter CBD Tincture  30 mL

4 / 5

Total CBD: 1000 – 2000 mg
CBD Potency : 33 – 66 mg/mL
Cost per mg CBD: $0.03 – $0.04
Extract type: Full-spectrum
THC Content: 0%

4 Corners offers this remarkable tincture for picky pets. Just in case your pet dislikes the pet tincture, you can opt for this Peanut Butter Tincture that contains hefty doses of pure hemp extracts combined with hemp seed oil. Thanks to its pleasant peanut butter flavor, your pet might just lick its bowl clean!

C) 4 Corners THC-Free CBD Tincture 

4 Corner Cannabis THC-free pet tincture
$39.99 – $349.99
4 Corners Cannabis

4 Corners THC-Free CBD Tincture 30 – 236 mL

4 / 5

Total CBD: 1000 – 14000 mg
CBD Potency : 33 – 58 mg/mL
Cost per mg CBD: $0.02 – $0.04
Extract type: CBD Isolate
THC Content: 0%

As the name implies, 4 Corners THC-free CBD tincture is meant for those that do not tolerate even trace amounts of THC in their product. Although the other pet products contain trace amounts of THC, none of them have psychoactive properties.

Made by infusing premium hemp extracts with hemp seed oil, this tincture is far gentler than other tinctures despite high doses of CBD. Available in four variations, including 1000 mg, 2000 mg, 7000 mg, and 14000 mg, this product is suitable for dogs, cats, and even horses. 

Safety & Third-Party Testing

We love it when companies are transparent about their practices, whether it’s manufacturing or testing products.

4 Corners posts all their third-party test results publically. The lab reports show results for contaminants, including pesticides and microbes.

Our only complaint is that some of the company’s tests seem to be a little bit too old and outdated.

4 Corners’ Shipping & Return Policy

At the moment, 4 Corners only ships to states within the USA. For returns, the company has a money-back guarantee if you’re disappointed with their products, provided that you contact them within 30 days of your initial purchase.

Final Verdict: A True “Soil to Oil” CBD Company

It’s apparent that 4 Corners is serious about its manufacturing policies. The company manages everything from cultivation to processing. A product’s efficacy depends on the hemp used, and since 4 Corners uses a special cultivar of organic hemp sourced from Colorado, it shows that they aim to offer top-quality products.

4 Corners also crafts their products keeping high potencies in mind. This ensures that they are effective and last longer. They also use a combination of other herbal ingredients that perform well in tandem with CBD.

Overall, the company uses innovative techniques to manufacture clean and pure CBD.
