Schedule I is the most restrictive category under the Controlled Substances Act, reserved for drugs the government classifies as having high abuse potential and no accepted medical use; kratom is not Schedule I. The 2016 federal proposal would have placed kratom’s alkaloids in Schedule I but was withdrawn.
Kratom therefore remains federally unscheduled, though the possibility of scheduling is a recurring theme in policy debate. See Controlled Substances Act and Kratom Legal Status.
