Exhibit 145 ยท Agency news release
Schedules of controlled substances: temporary placement of 7-hydroxymitragynine and mitragynine (proposed amendment; notice of intent, Federal Register, 14 October 2026)
HHS recommended scheduling thresholds of more than 1 mg of 7-OH per gram in solids or 1 mg per mL in liquids, with a ratio test. On 14 October 2026 DEA published a proposed amendment, a notice of intent, that withdraws its July 2026 notice of intent and uses those thresholds. On a solids basis 1 mg/g is 0.1 percent, twice the 0.050 percent w/w in the July notice.
