About the product

Cannabinoid breakdown per mL

CBD (mg / mL)


THC (mg / mL)


Other cannabinoids (mg / mL)

4 Corners Cannabis also claims to have 10 mg of CBD per 1 mL. We found that 1 mL contains a total of 11.306 mg of cannabinoids, including 9.437 mg of CBD and 0.313 mg of THC.

The info above gives you an idea of what’s in this extract. 4 Corners Cannabis’ serving size is a lot more complicated. It’s one of the most confusing serving size recommendations that we’ve come across. 4 Corners Cannabis suggests 3 drops per 10 lbs of body weight. They claim this product contains 0.50 mg of CBD per drop. A 200-pound person would, therefore, need 60 drops or 30 mg of CBD per serving, which equals 3 mL of extract.

About the company

4 Corners Cannabis is a small company located in Bayfield, Colorado. They launched in 2013 and have 5 acres of hemp and a 4,000 square-foot lab. They also own cannabuddies.com.

The good:

  • B+ rating by the Better Business Bureau. Update (1/2020): upgraded to A- BBB score. Looks like they take care of customers.
  • 4 Corners Cannabis’ Oral Tincture tested for more cannabinoids than claimed by their front label, and they were within 13.1% accuracy. Their CBD claims were within 5.6% accuracy. The product also contained a wide range of cannabinoids.

The bad:

  • Their serving size is listed as “3 drops per 10 lbs. of body weight.” This dosing info may confuse the average person looking for quick relief without the additional math. Many CBD products list a serving size in mL and provide a dropper that matches that serving size, which is easier to understand and dose. Bodyweight is also not the best indicator of a CBD serving size for numerous reasons.
  • Their name is 4 Corners Cannabis, which many retailers and consumers may not like. Hemp companies typically stay away from the terms “cannabis” or “marijuana” to avoid stigmas.

The internet:

  • An extensive internet search for 4 Corners Cannabis found no reports of inconsistency, toxins, pesticides, metals, fake products, or unethical business practices.

Other sizes available

4 Corners Cannabis also offers the Oral Tincture in potencies of 250 mg ($59.99), 500 mg ($109.99), and 1000 mg ($199.99). However, these higher potency versions are not the same formula as the 100 mg ($29.99) bottle that we tested and we can’t provide information on their cannabinoid levels, accuracy, or value.
