As of November 12, 2026, MGM-16 (9-fluoro-dihydro-7-hydroxymitragynine) is illegal to sell (federally scheduled; state law on file reads gray area) in Wyoming. Federal Schedule I (DEA temporary order, drug code 9674), effective 2026-08-26 to 2028-08-26. Controlling source: W.S. 35-7-2201 and 35-7-2202 (kratom product regulation).

Wyoming’s kratom product act (W.S. 35-7-2201 to -2203, 2026 SF0056, Enrolled Act 44, effective July 1, 2026) makes it a misdemeanor to sell a kratom product that is 'adulterated' (the addition of a controlled substance, a synthesized alkaloid or a semi-synthesized alkaloid into a kratom product) and to manufacture, package, distribute or label a kratom product that contains synthesized or semi-synthesized alkaloids; it also sets a 2% 7-hydroxymitragynine cap, age 21 and labeling. MGM-16 (9-fluoro-dihydro-7-hydroxymitragynine) is a synthesized or semi-synthesized alkaloid derivative (a fluorinated, chemically altered 7-hydroxymitragynine scaffold). The same act provides that 'Kratom product' 'shall not include any synthesized alkaloid or semi-synthesized alkaloid'. A product mixing the compound with natural kratom alkaloids is an adulterated kratom product and is barred; whether a tablet whose only active ingredient is the compound is a 'kratom product' at all depends on reading that exclusion, so the reach is definitional and the row is restricted. Federal scheduling: 35-7-1011(d) requires the Attorney General to control a federally scheduled substance within 30 days by emergency rule followed by a permanent rule; control runs through that rulemaking, and the Attorney General's 2026 emergency rules located (April 16, August 13 and September 2, 2026) cover other substances, with none located for MGM-15 or MGM-16. Checked and absent: named listing in 35-7-1014, 7-OH scheduling, whole-plant ban; no state analog act with a scheduled kratom parent. Federal overlay: MGM-15 and MGM-16 are federally Schedule I under the DEA temporary scheduling order (DEA-1644, FR Doc. 2026-17429, effective 2026-08-26 to 2028-08-26); this row reports state law only.
(i) "Adulterated" means the addition of a controlled substance, a synthesized alkaloid or semi-synthesized alkaloid into a kratom product; ... (vi) "Kratom product" means a food or dietary supplement that consists of or contains any part of the kratom leaf, kratom leaf extract or any kratom alkaloid, kratom constituent or kratom metabolite. "Kratom product" shall not include any synthesized alkaloid or semi-synthesized alkaloid; ... (viii) “Semi-synthesized alkaloid” means an alkaloid or alkaloid derivative contained in kratom leaf extract that has been exposed to chemicals or processes that would confer a structural change in the alkaloids, including but not limited to oxidation, reduction and ring opening and closing, resulting in material that has been chemically altered;
Among Wyoming’s 6 neighbors, Colorado, Idaho, Montana, Nebraska, South Dakota and Utah are illegal, the same posture as Wyoming.

As used in this act: (i) "Adulterated" means the addition of a controlled substance, a synthesized alkaloid or semi-synthesized alkaloid into a kratom product; (ii) “Alkaloid fraction” means a portion of a plant or plant extract that contains primarily alkaloid compounds; (iii) “Controlled substance” means as defined by W.S. 35-7-1002(a)(iv); (iv) “Kratom leaf” means the leaf of the mitragyna speciosa plant in fresh, dehydrated or dried form; (v) "Kratom leaf extract" means the material extracted from a kratom leaf through the application of a solvent consisting of water, ethanol, food-grade carbon dioxide or another solvent allowed by federal or state law to be used in the manufacturing of a food ingredient; (vi) "Kratom product" means a food or dietary supplement that consists of or contains any part of the kratom leaf, kratom leaf extract or any kratom alkaloid, kratom constituent or kratom metabolite. "Kratom product" shall not include any synthesized alkaloid or semi-synthesized alkaloid; (vii) “Retailer” means a business of any kind at a specific location that sells kratom products to a user or consumer; (viii) “Semi-synthesized alkaloid” means an alkaloid or alkaloid derivative contained in kratom leaf extract that has been exposed to chemicals or processes that would confer a structural change in the alkaloids, including but not limited to oxidation, reduction and ring opening and closing, resulting in material that has been chemically altered; (ix) "Synthesized alkaloid" means an alkaloid or alkaloid derivative of the kratom leaf that has been created by chemical synthesis or biosynthetic means, including fermentation, recombinant techniques, yeast-derived techniques and enzymatic techniques. "Synthesized alkaloid" shall not include an alkaloid or alkaloid derivative of the kratom leaf that has been created by traditional food preparation techniques, including but not limited to heating or extracting; (x) “This act” means W.S. 35-7-2201 through 35-7- 2203. 35-7-2202.
