What the record says

On September 22, 2026 the Administrator of the Narcotics Enforcement Division, Hawaii Department of Law Enforcement, issued an Emergency Controlled Substance Scheduling Action under HRS 329-11(e) placing MGM-16 (9-fluoro-dihydro-7-hydroxymitragynine) in Schedule I by adding a new HRS 329-14(b) entry (50), 'commonly known as MGM-16; also known as 9-fluoro-dihydro-7-hydroxymitragynine: or 10-fluoro-dihydro-7-hydroxymitragynine (depending on numbering convention)', including its isomers, esters, ethers, salts, and salts of isomers, esters, and ethers. The order states that it takes effect September 22, 2026. The same order also scheduled 7-hydroxymitragynine (above the federal threshold) and mitragynine pseudoindoxyl. Under HRS 329-11(e) an emergency scheduling is temporary and is nullified if the next regular session of the legislature does not enact the corresponding change to chapter 329. The order is posted as an image-only PDF on the Department of Law Enforcement site; its wording was read from that official file by optical character recognition, so the statutory authority (HRS 329-11) is the machine-verifiable law text for this row. Also checked: HRS 329-11(d) federal incorporation (the Department designates federally scheduled substances by posted notice; the May 15, 2026 notice did not include MGM-16); the codified Schedule I list in HRS 329-14 (last amended L 2025, c 107) does not name MGM-16 or any kratom alkaloid; Hawaii has no enacted kratom consumer protection act (HB 717 was carried over to the 2026 session), no whole-plant ban and no controlled-substance analog statute. The order states that it takes effect on the posting date, while HRS 329-11(e) calls for thirty days' public notice before an emergency scheduling takes effect; on that strict reading the earliest effective date is 2026-10-22, which has also passed. The control is nullified unless the 2027 regular session enacts it. Federal Schedule I (temporary, DEA-1644) applies regardless of this state row; the state row governs after the order lapses.

Controlling language, verbatim

administrator may make an emergency scheduling by placing a substance into schedule I, II, III, IV, or V on a temporary basis, if the administrator determines the action is necessary to address or avoid a current or imminent danger to the health and safety of the public. ... If a substance is added or rescheduled under this subsection, the control shall be temporary and, if the next regular session of the state legislature has not enacted the corresponding changes in this chapter, the temporary designation of the added or rescheduled substance shall be nullified.

[Subsection effective January 1, 2024. 
For subsection effective until December 31, 2023, see above.]
  If a
substance is added, deleted, or rescheduled as a controlled substance under
federal law and notice of the designation is given to the department of law
enforcement, the department of law enforcement shall recommend that a
corresponding change in Hawaii law be made.  The department of law enforcement
shall similarly designate the substance as added, deleted, or rescheduled under
this chapter, after the expiration of thirty days from publication in the
Federal Register of a final order, and this change shall have the effect of
law.  If a substance is added, deleted, or rescheduled under this subsection,
the control shall be temporary and, if the next regular session of the state
legislature has not made the corresponding changes in this chapter, the
temporary designation of the added, deleted, or rescheduled substance shall be
nullified.

    
(e)  The
administrator may make an emergency scheduling by placing a substance into
schedule I, II, III, IV, or V on a temporary basis, if the administrator
determines the action is necessary to address or avoid a current or imminent
danger to the health and safety of the public.  In making the determination of
whether to emergency schedule a substance, the administrator shall assess the
degree of danger or probable danger of the substance by considering the
following:

     (1)  The actual or possible abuse of the substance
including:

          (A)  Its history and current pattern of abuse;

          (B)  The scope, duration, and significance of
abuse; and

          (C)  A judgment of the degree of actual or
possible detriment that may result from the abuse of the substance; and

     (2)  The risk to public health.

The department shall post a public notice thirty
days prior to the effective date of the emergency scheduling action, at the
state capitol, in the office of the lieutenant governor, and on the
department's website for public inspection.  If a substance is added or
rescheduled under this subsection, the control shall be temporary and, if the
next regular session of the state legislature has not enacted the corresponding
changes in this chapter, the temporary designation of the added or rescheduled
substance shall be nullified. [L 1972, c 10, pt of §1; am L 1987, c 113, §1; am
