What the CDC's 2026 Kava Report Actually Found
Looking beyond the headlines at one of the most significant recent U.S. reports involving kava.
In April 2026, the Centers for Disease Control and Prevention published one of the most significant recent U.S. reports involving kava.
The report examined kava-related calls made to American poison centers between 2000 and 2025. According to the CDC, reports declined following the FDA's 2002 consumer advisory about possible liver injury but began rising again around 2011. A total of 203 kava-related reports were recorded in 2025.
Those numbers deserve attention, but they also require context.
A poison-center report does not automatically prove that kava caused a person's symptoms. Poison-center databases collect reports about possible exposures, and many cases may involve incomplete information, uncertain product contents or the use of multiple substances.
One of the CDC report's most important findings was that an increasing share of reported cases involved products or situations that also included kratom. Kratom is a separate botanical with different active compounds, effects and safety concerns.
The CDC found that the rise in serious outcomes occurred alongside increased involvement of kratom-containing kava products. The authors specifically highlighted commercial products combining the two botanicals as an area of concern.
This distinction is especially important for traditional kava businesses. A bowl of traditionally prepared kava root and water should not automatically be treated as identical to a concentrated shot containing kava extract, kratom, sweeteners and other active ingredients.
The CDC acknowledged that the American kava marketplace has changed significantly. Consumers can now purchase traditional root powder, capsules, extracts, concentrated beverages and ready-to-drink products. These products can have very different ingredients and strengths.
The report also does not calculate the overall rate of injury among all U.S. kava consumers. Without reliable national consumption data, poison-center reports cannot tell us what percentage of kava users experience an adverse event.
Nevertheless, the report provides several valuable lessons.
Consumers should know exactly what is in the product they are drinking. Businesses should clearly distinguish kava from kratom, avoid unlabeled mixtures and maintain detailed information about suppliers, batches and preparation methods.
People should also avoid combining kava with alcohol, sedatives or other substances that can affect the central nervous system unless they have discussed the combination with a qualified healthcare professional. The National Center for Complementary and Integrative Health advises that kava should not be used together with sedating substances such as alcohol or benzodiazepines.
The responsible takeaway is not that all kava is suddenly unsafe. It is that the category has become more complicated. Traditional preparations, extracts and combination products should not be casually grouped together.
As kava becomes more popular, transparency, responsible service and accurate customer education will become increasingly important.
