A plant-based drink once revered in Pacific Island traditions is now at the center of a public health crisis in the United States. Kava, a root-based beverage marketed as a hangover-free, natural alternative to alcohol, has triggered a dramatic surge in poisonings, with emergency calls involving the substance rising 256% from 57 in 2011 to 2023 in 2025, according to data from the University of Virginia Health's Blue Ridge Poison Center. The substance, traditionally used in ceremonial settings for its calming properties, is now sold in concentrated extracts, capsules, and ready-to-drink formats at trendy cafes and vape shops. However, the unregulated potency of these products—often containing two to ten times more kavalactones, the active compounds in kava—has raised alarms among public health officials.

The shift in demographics of those affected by kava poisonings is striking. In the early 2000s, most calls to poison centers involved young children and women. Today, the overwhelming majority of exposures are among men aged 20 and older, a trend attributed to aggressive marketing campaigns near college campuses and in vape shops, according to the CDC. This demographic shift underscores a growing normalization of kava use among young adults, often framed as a "wellness" product rather than a substance with serious health risks.

Experts warn that the combination of kava with other substances, particularly kratom—a psychoactive plant with opioid-like effects—has exacerbated the crisis. By 2025, kratom was involved in 30% of kava-related poison center calls, leading to severe outcomes such as seizures, hypertension, and tremors. The unregulated nature of these products, which are not subject to FDA oversight, has allowed dangerous interactions to proliferate. "We're seeing a resurgence of calls as new kava products enter the market, often mixed with other substances like kratom," said Dr. Chris Holstege, director of the Blue Ridge Poison Center. "These combinations can lead to life-threatening effects that weren't previously seen."

The data reveals a troubling trajectory in the severity of kava-related poisonings. Between 2000 and 2025, poison centers logged 3,101 calls related to kava exposure. Before the FDA's 2002 warning linking the substance to liver injury, reports peaked at 331 in 2001, only to drop by 87% to 42 in 2010. However, the market rebounded sharply after 2011, fueled by new product formats and wellness marketing. By 2024, 39% of kava exposures led to severe medical outcomes—up from just 12% in 2000. Eight deaths were recorded over the 25-year period, a grim reminder of the risks associated with unregulated consumption.

Public health officials emphasize that the rise in kava-related poisonings highlights gaps in regulation and consumer awareness. While traditional kava ceremonies involve controlled preparation and consumption, commercial products often lack transparency about their potency and potential interactions. The CDC's Morbidity and Mortality Weekly Report, which analyzed data from all 53 U.S. poison centers, underscores the need for stricter oversight. Each call logged in the National Poison Data System provides a critical snapshot of trends, from the age and gender of those affected to the severity of symptoms and hospitalization rates.

As kava continues to gain traction in wellness culture, the call for action grows louder. Public health advocates urge consumers to exercise caution, noting that the risks of liver injury, neurological damage, and severe toxicity are not confined to illicit use. "This is a public health issue that requires immediate attention," said Dr. Holstege. "Until these products are properly regulated and labeled, the risk to consumers remains alarmingly high." The story of kava in the U.S. serves as a cautionary tale about the unintended consequences of unregulated wellness trends—and the urgent need for policies that prioritize public safety over commercial interests.

The resurgence of kava-related poisonings has also sparked debate among medical professionals and regulators. While some argue that kava's traditional use in Pacific Island cultures warrants a more nuanced approach, others stress the importance of clear warnings about its risks. The FDA's 2002 advisory, which led to a temporary decline in poison center calls, was based on evidence linking kava to liver injury. However, the recent spike in cases suggests that the lack of long-term safety data and inconsistent product standards have created a perfect storm for harm.

For consumers, the message is clear: the allure of a "natural" alternative to alcohol comes with significant risks. Health experts recommend consulting medical professionals before using kava or any unregulated supplement, particularly when combined with other substances. The rise in poisonings underscores the need for greater transparency from manufacturers and stronger oversight from regulators. As the demand for wellness products continues to grow, so too must the commitment to ensuring that these products do not compromise public health.

The data from the past 25 years offers a sobering look at the consequences of unregulated consumption. From the initial drop in calls after the FDA's 2002 warning to the sharp resurgence in 2011, the story of kava in the U.S. reflects the challenges of balancing cultural traditions with modern public health concerns. With the number of serious outcomes climbing and the demographic of users shifting toward young adults, the urgency for action has never been greater. The question now is whether policymakers, manufacturers, and consumers will take the necessary steps to prevent further harm.

Single-substance kava exposures typically caused vomiting, drowsiness, dizziness, and rapid heartbeat. These symptoms, while uncomfortable, were generally manageable in clinical settings. However, the situation changed dramatically when kava was combined with kratom. In 128 documented cases, the combination led to severe outcomes: seizures, tremors, and dangerously elevated blood pressure. These effects suggest a synergistic toxicity that neither substance alone could produce. Between 2000 and 2025, hospitalization rates for kava exposures averaged 20 percent annually, but no consistent trend emerged. What did rise sharply was the proportion of serious medical outcomes. In 2000, only 12 percent of cases resulted in critical conditions, but by 2024, that number had tripled to 39 percent. Over the same period, eight deaths were recorded, a grim testament to the growing risks associated with these substances.

Of all kava-related calls to poison control centers, 43 percent involved multiple substances. For years, alcohol and benzodiazepines were the most common co-ingested ingredients. But in 2017, kratom entered the picture. By 2025, it was linked to 30 percent of multiple-substance kava exposures. This shift reflects a broader trend in substance use patterns, as kratom gained popularity as an alternative to opioids and other depressants. The rise in kratom's role is particularly concerning because its interaction with kava appears to amplify the risk of severe health complications.

Liver enzyme elevations, a key indicator of potential liver damage, were also more prevalent in cases involving both kava and kratom. Studies suggest that the combination may overwhelm the liver's metabolic pathways, leading to more pronounced toxicity. This finding aligns with reports from poison centers, which have seen a surge in calls related to these substances. The increase in kava-related poison center calls mirrors a broader cultural shift: the rise of nonalcoholic beverages marketed as social alternatives. These products, often sold online and in vape shops, are promoted as ways to feel "social" without the hangover. This marketing strategy has contributed to a demographic shift, with young adults now comprising the majority of exposure reports.

Public health officials have raised alarms about the lack of regulation surrounding kava and kratom products. Unlike countries such as Australia, which limits daily kava intake to 250 mg of kavalactones, the United States has no such restrictions. In the US, kava and kava-kratom products are completely unregulated. Some manufacturers even advertise servings containing more than 250 mg of active ingredients, often with multiple servings per container. Without standardized manufacturing processes or content verification, the actual potency of these products could be significantly higher than labeled. Chronic use of high-potency formulations has been linked to severe health risks, including liver damage, seizures, rapid heartbeat, and hypertension.

Experts warn that the continued promotion of these products without proper oversight poses a significant public health threat. Researchers emphasize the need for consumer education about potential adverse effects, as well as greater clinical awareness of evolving exposure patterns. The absence of regulatory safeguards, combined with aggressive marketing, creates a dangerous environment for users who may not fully understand the risks. As one health official noted, "These new kava products are found in stores throughout our area. The public needs to be aware of potential complications associated with the consumption of these products." Without intervention, the trend toward more severe outcomes could continue to escalate.
