Heavy Metals In CBD: What You Should Know

At Premium CBD, our number one goal is to provide a resource for CBD and Delta-8 users to find pure, unadulterated products for their health. As such, we only offer products that we have verified to be tested by ISO-accredited labs for pesticides, heavy metals, residual solvents, and microbial contaminants. We haven’t specifically dove into the implications of heavy metals in CBD yet, and that’s what this blog post is for. 

CBD is not regulated by any governing force. To legally produce CBD in the United States, companies must follow specific guidelines. However, these guidelines do not carry over into testing products or ensuring they are free from contaminants. 

As such, there are plenty of CBD products out there that are contaminated and unsafe for consumption. If you’re wondering where to get safe CBD, be sure to check out the Premium CBD database, where you can buy CBD online and feel confident in your purchase.

Avoiding heavy metals in your daily life is important. Long-term exposure to certain heavy metals can cause serious health complications. Since CBD is often taken as a regular supplement, it is crucial to find products that are free from heavy metals and other contaminants to prevent any health risks. In an unregulated market, it’s not as easy as you may think. 

What are the possible heavy metals in CBD?

Heavy metal contaminants can originate from the manufacturing process and from soil contamination from the growing process. Hemp is especially absorbent and is often used to help pull contaminants from the ground to clean the soil for other agricultural purposes. However, the contaminants that hemp pulls from the soil end up in the hemp plant itself, and this can seriously contaminate any products made from that plant. 

Beyond the soil, machinery can also contaminate otherwise pure CBD products during their production. 

Regardless of if contamination occurs because of the soil or the production process, the result is the same: concentration of heavy metals in the final product. These heavy metals easily transfer to humans or pets when they ingest the products. 

Heavy metals in CBD can include lead, mercury, cadmium, thallium, chromium, and arsenic. 

What are the health risks of heavy metals?

Ingesting heavy metals can cause serious health risks. Data suggests that adverse health effects from cadmium can occur at low exposure levels. Possible complications from cadmium exposure may include kidney damage, bone effects, and fractures. 

Mercury exposure, which is commonly caused by fish sources, typically does not pose a significant health risk. However, people with high fish consumption may end up with levels of mercury in their body that can cause neurological damage. High presence of mercury in other products can also cause damage. 

Lead exposure most often occurs from both food and air sources. Children are more susceptible to the neurotoxic side effects from lead exposure than adults. 

Long-term arsenic exposure is linked to increased risks of skin cancer, skin lesions, and changes to skin pigment. Repeated arsenic inhalation is also associated with lung cancer. 

As you can tell from this information, exposure to heavy metals is not a good thing. It can cause serious health risks, especially with repeated exposure. 

How do I know if there are heavy metals in CBD products I use?

While regulation is lacking for CBD products, there are ways to figure out if your products are safe for consumption. This starts by reading the COA on your product. 

COA stands for Certificate of Analysis, which is a document from a laboratory showing test results for various compounds. Not all laboratories are the same, though, so COAs should always come from ISO-accredited laboratories, because it means the lab has proven their ability to test products in accordance with industry standards. 

Even if the product has a COA from an ISO-accredited laboratory, you can’t be sure a product is free from heavy metals unless the lab report shows testing for that specific contaminant. 

Check the COA for the heavy metals analysis and verify that the product has been tested for harmful contaminants. If you do not see a heavy metals analysis on the lab report, the laboratory likely did not test the product for heavy metals. 


Surprisingly to many CBD consumers, many products are not tested for heavy metals. It is not uncommon to find a lab report for CBD with an analysis that only shows a few test items. Commonly, CBD companies request a cannabinoid analysis to verify the amount of CBD and THC in the product. Just because a company tests for these few items does not mean that they test for all possible impurities. 

Premium CBD verifies products for you

If it sounds like a hassle to verify your CBD products for heavy metal contamination, you’re not alone. The process can take a long time with all of the tracking down you have to do to find the COA on some products. 

Reputable companies will make their COAs easily accessible to all prospective consumers. If the company does not provide a COA, avoid the product at all costs. Consumers deserve access to information about everything in their CBD products, not just the cannabinoid content. 

At Premium CBD, we’ve made it our mission to make finding safe, pure CBD easy. We have developed a thorough verification process to ensure the purity of various CBD products on the market. We make sure that products are tested at ISO-accredited laboratories for all possible contaminants, not just a few. 

Utilizing our verification process, we have scanned hundreds of CBD products on the market for purity and potency. While the majority of the products did not make the cut, we did find a selection of high quality CBD products that are verified safe and potent. Those products are what you see in the Premium CBD database. 

You can search through our selection of premium CBD tinctures, safe CBD vapes, CBD topicals, pure CBD pet products, and so much more.
