Washington, DC: CBD-infused products commercially available in retail stores and online often contain heavy metals, such as lead and arsenic, and typically contain less-than-advertised quantities of cannabidiol, according to a network news investigation of third-party testing results.
Investigators reviewed results for over 240 CBD-infused products. Their analysis determined that "70 percent" of the products were found to be "highly contaminated with heavy metals like lead and arsenic, herbicides like glyphosate and a host of other contaminants including pesticides."
In addition, "more than half" of the products tested contained percentages of CBD that were inconsistent with the product's labeling. Some products tested negative for any trace of CBD.
The results are consistent with those of previous reports – such as those here, here, here, here, here, here, here, here, here, here, here, and here – which similarly determined that many commercially available CBD-infused products are of variable potency and may contain potentially harmful adulterants and heavy metals.
Earlier this month, NORML submitted written testimony to the US Food and Drug Administration recommending that the FDA provide regulatory guidelines governing product manufacturing, standardization, and quality.
