Study Finds Only 7% of CBD Brands Conduct Proper Lab Testing

Leafreport released the findings from their expansive CBD testing study that revealed some pretty alarming results. According to their study, only 7% of CBD brands they sampled actually conduct legitimate contamination testing for pesticides, heavy metals and microbial contamination.

Leafreport is an Israeli company founded in 2019 that does product reviews, independent testing and provides educational resources for consumers. The company produces studies on CBD products in the market and reports their results on its website. Back in 2020, the watchdog company conducted independent lab testing on 22 different CBD-infused beverages and found a lot of inconsistencies with the actual amount of CBD found in the beverage and what the product’s label claimed.

In this latest study, finalized in late May of 2022, the consumer advocacy group found a lot of inconsistencies throughout the CBD market. For their study, they reviewed 4,384 products from 188 brands, with the goal of looking at overall transparency in the CBD products market. Judging by the results they share, the CBD market is unsurprisingly not very transparent.

Here are some highlights from this most recent study:

• 20% of the brands reviewed didn’t carry out any purity tests to check for the presence of microbes, pesticides, or heavy metals. In 2021, 25% of the brands Leafreport reviewed didn’t carry out any purity tests.
• 42% of brands test almost all of their products for potency (90%-100% accurate) and share their third-party lab results with consumers — the same as in 2021.
• Only 12% of brands had all their products fall within acceptable potency variance limits.
• 88% of brands that tested their products for potency had at least one product test beyond the 10% variance for potency, in comparison to 84% in 2021.
• 28% of brands didn’t carry out any testing at all for pesticides (such as glyphosate), 26% didn’t test for the presence of any heavy metals (such as arsenic), and 24% didn’t test for microbes (like bacteria).
• Two brands carried out no lab testing at all for either purity or potency, compared to 3 brands in 2021.
