“In view of the growing market for such lifestyle food supplements, the effectiveness of the instrument of food business operators’ own responsibility for food safety must obviously be challenged,” he adds.
“Obviously, the manufacturers have – deliberately or in complete ignorance of the legal situation – placed unsafe and unapproved products on the market and thus exposed the consumer to an actually avoidable risk.
The study’s findings provoked a strong reaction from CBD developers and industry groups alike, who objected to the study’s tone and approach in which it came to its conclusions.
The team also highlight the need to characterise and toxicologically assess CBD degradation products within the context of the novel food registration process.
“In our opinion the systematically high THC content of CBD products is clearly a “scandal” on the food market,” the study says, led by Dr Dirk Lachenmeier, food chemist, toxicologist at the Chemical and Veterinary Investigation Laboratory (CVUA) of Karlsruhe.
The research team point to findings from cannabis oil products demonstrating that labelling information for CBD and THC was often different from the actual contents.
“If you look at all the tests which are done, we see a high percentage of current products are not okay and that the info on the label does not matches with the content,” says Waldo van der Hel, partner at Renviden, a Dutch-based company that develops products based on a patented micro-encapsulated full spectrum CBD-oil.

High-potency CBD oils in particular amplify concerns about contamination. As Ronay explained, concentrating for potency involves concentrating everything else in and on the hemp plant, too. “How do you know what’s in it or what’s safe? People are looking for a cure and for health and facing the unknown,” Ronay said.
“When you’re talking about strength, you’re talking about potency,” explained Adie Rae , a science adviser to Weedmaps News and an academic researcher with a Ph.D. in neuroscience who has been studying cannabinoids since 2004. “And that means how much CBD per volume.”

Cannabidiol Life’s most potent offering is a perfect example of why it’s important to measure a CBD oil’s strength by volume. At 3,000 milligrams CBD, this whole plant hemp extract oil contains more cannabidiol than most products on the market. But its potency isn’t as extreme as it may appear. This is a 60 milliliter bottle, putting CBD potency at a humbler 50 mg/mL — therapeutically beneficial, but not chart-topping. Still, because Cannabidiol Life contains so much CBD, you can easily obtain 75–100 mg/mL doses, or higher, if required.
The oils below are all CBD-heavy, at concentrations way above the average product, with prices to match. We favored broad-spectrum oils due to their added therapeutic benefits. And remember, if you want to make your CBD oil stronger, all you need to do is take more of it!
The boundaries between isolates, distillates and full-spectrum CBD oils aren’t always so clear. For example, a strong CBD oil made with a 99.7% pure isolate may also contain a range of minor cannabinoids and terpenes because it uses a broad-spectrum hemp seed oil as a carrier.
But potency (mg/mL) is only part of the larger strength equals efficacy equation. Research is still ongoing, but most experts agree that CBD on its own is going to be less effective overall than a full-spectrum oil containing roughly the same amount of CBD.
