Evidence
On January 13, 2026, Senator Roger Marshall sent a follow-up letter to the DEA, reiterating his call for immediate action to schedule 7-hydroxymitragynine (7-OH) and related synthetic opioid products.
On October 28, 2025, Senator Marshall sent a letter to DEA Administrator Terrence Cole, urging the agency to take action and emergency schedule 7-hydroxymitragynine (7-OH) and related products as Schedule I controlled substances.

On December 2, 2025, the Justice Department, together with the FDA, announced the seizure of approximately 73,000 units of 7-hydroxymitragynine (7-OH) products at three warehouses.
On October 24, 2025, Senator Marshall toured the Clinical Reference Laboratory to raise awareness about the growing threat of 7-hydroxymitragynine (7-OH), a powerful, unregulated opioid compound derived from the kratom plant.
Assessments
Senator Roger Marshall made repeated and serious efforts to urge the DEA to schedule 7-hydroxymitragynine (7-OH) and related synthetic opioids as controlled substances. This included sending multiple letters to the DEA, public advocacy, and raising awareness. However, there is no evidence that the DEA actually scheduled 7-OH or related products in response. Federal seizures of 7-OH products occurred, but this does not equate to their formal scheduling. Therefore, while the promise itself (to urge the DEA) was actioned by the Senator, the intended outcome (DEA scheduling 7-OH) was not delivered, despite substantial effort.
