A bill for an act designating kratom as a schedule I controlled substance, and making penalties applicable.

HF 2133 designates kratom (including all parts of the Mitragyna speciosa plant and its derivatives like mitragynine) as a hallucinogenic Schedule I controlled substance in Iowa. This bill directly affects anyone possessing kratom, imposing escalating penalties: a first offense is a serious misdemeanor (up to 1 year in jail and up to $2,560 fine), subsequent offenses become aggravated misdemeanors (up to 2 years jail, up to $8,540 fine), and a third conviction is a class D felony (up to 5 years jail, up to $10,245 fine). The law creates new criminal penalties for possession without specifying medical or personal use exceptions. The bill was introduced on January 21, 2026, and remains pending.
