The Scientist Trying to Keep Kratom Legal Has Not Disclosed Longstanding Ties to Kratom Lobbyists

Jin Ke Wang for ProPublica The leading scientist urging policymakers not to criminalize kratom, a substance that has left a trail of death and addiction around the world, has routinely failed to disclose longstanding financial ties to the industry’s most powerful lobbying group, ProPublica has found. University of Florida professor Christopher McCurdy has accepted travel reimbursements, donations to his university’s foundation and funding for an annual symposium on research into the leaf’s medicinal potential from the American Kratom Association — none of which has been disclosed in his conflict of interest statements or on the papers he publishes. The fight to keep kratom legal across the country has taken on increased urgency as more potent kratom derivatives have appeared on store shelves and evidence has mounted of the leaf’s risks to users’ health. According to the Centers for Disease Control and Prevention, 5,200 people in the United States died from drug overdoses involving kratom between 2020 and 2024. And calls to poison control centers involving kratom have spiked 1,200% in the last decade.
