Study: 7% of CBD Brands Conduct Proper Lab Testing
CAL • Jun 17, 2022

The results of Leafreport's large-scale CBD testing investigation were announced, and the conclusions were worrisome.

The results of extensive CBD testing study were announced, and the conclusions were worrisome. Only 7% of the CBD companies they evaluated, according to their research, undergo legitimate contamination testing for pesticides, heavy metals, and microbiological contamination.


Leafreport is an Israeli company that conducts product reviews, independent testing, and provides consumer education resources. The firm conducts research on CBD products on the market and publishes the findings on its website. The watchdog organization conducted independent lab testing on 22 different CBD-infused beverages in 2020 and discovered numerous discrepancies between the actual quantity of CBD present in the beverage and what the product's label claimed.


The consumer advocacy group discovered a lot of variations throughout the CBD market in this newest survey, which was completed in late May of 2022. They looked at 4,384 goods from 188 brands for their analysis, with the purpose of examining overall transparency in the CBD industry. The CBD market is, predictably, not very transparent, based on the data they share.


  • Twenty percent of the products tested did not conduct any purity tests to look for microorganisms, pesticides, or heavy metals. In 2021, 25% of the brands examined by Leafreport did not conduct any purity tests.
  • In 2021, 42 percent of brands tested practically all of their products for potency (90 percent-100 percent correct) and shared the results with consumers from third-party labs.
  • Only 12% of brands were able to keep all of their goods within acceptable potency variance limits.
  • In comparison to 84 percent in 2021, 88 percent of brands that tested their products for potency had at least one product test outside the 10% variation for potency.
  • Pesticides (such as glyphosate) were not tested in 28 percent of cases, heavy metals (such as arsenic) were not tested in 26 percent of cases, and microorganisms were not tested in 24 percent of cases (like bacteria).
  • In 2021, two brands did not conduct any lab testing for purity or potency, compared to three brands in 2021.
