SS/SB 1605 - This act makes 7-hydroxymitragynine (7-OH) in amounts concentrated at a level above 1,000 parts per million on a dry-weight basis a Schedule I controlled substance.

This provision is substantially similar to HB 1614 (2026).

Additionally, this act prohibits the preparation, distribution, advertisement, sale, or offering for sale of a kratom product that: (1) is adulterated; (2) is sold to a person under 21 years of age; (3) contains 7-hydroxymitragynine concentrated at a level above 1,000 parts per million on a dry-weight basis; (4) mimics candy or is appealing to children; or (5) is combustible or intended for vaporization. Kratom products shall contain specified labels that include disclaimers. A person who violates this provision will be deemed to have engaged in an unlawful practice in violation of the state's Merchandising Practices Act.

Finally, it shall be an infraction for a person to sell a kratom product to a person under 21 years of age, as described in the act.

These provisions are substantially similar to SCS/SB 927 (2026).
