What the record says

Maine does not reach 9-OH. Its scheduled drugs are those named or described in 17-A M.R.S. 1102 (Schedules W, X, Y and Z), and no entry names 9-OH, 9-hydroxycorynantheidine, mitragynine, 7-hydroxymitragynine, kratom or Mitragyna speciosa. A search of the Maine Revised Statutes, current through October 1, 2026, returns no text for kratom, mitragynine or Mitragyna (the same search returns hits for a control term). Maine has no kratom consumer protection act, so there are no age, labeling, registration, testing or form rules; no whole-plant ban; no provision adopting federal scheduling (the schedules are statutory); and no separate controlled substance analog statute. Schedule W, paragraph I covers any compound, mixture or preparation containing narcotic drugs in any quantity, and 17-A M.R.S. 1101(6)-(7) defines narcotic drug to include any opiate, meaning a substance with analgesic and addiction-forming liability similar to morphine. That effect-based reading was considered and is not applied, consistent with this database’s Maine rows for 7-OH and MGM-15: the federal schedule has the same structure, yet DEA schedules new opioid-acting substances individually, and no Maine authority has applied Schedule W to any kratom alkaloid. 9-OH is a weaker, partial opioid agonist than 7-OH, so the reading would be no stronger here. Trace 7-OH is not state-controlled. 9-OH is not federally scheduled; federal Analogue Act and FDA exposure are interpretive.

Any substance having an analgesic and addiction forming or addiction sustaining property or liability similar to morphine or capable of conversion into a drug having such analgesic and addiction forming or addiction sustaining property or liability.
