Pending deadlines

• 2026-08-01 · Federal · DEA temporary Schedule I order for mitragynine pseudoindoxyl, MGM-15, MGM-16 - effective on Federal Register publication (DEA NOI 2026-07-01)
• 2026-08-05 · Federal · DEA temporary Schedule I - mitragynine pseudoindoxyl, MGM-15, MGM-16 (DEA-1644 / FR 2026-17429)
  Second DEA Notice of Intent filed with the Federal Register on 7/1/2026 (companion to the 7-OH NOI, DEA-1570), placing three 7-OH-RELATED substances — mitragynine pseudoindoxyl (MP), MGM-15, and MGM-16 — into Schedule I under 21 U.S.C. 811(h). HHS confirmed these have no accepted medical use and a high potential for abuse. Same procedural clock as the 7-OH NOI: 30-day notice period, temporary order cannot issue before ~2026-08-05, effective on Federal Register publication of the order, 2-year duration (+1 yr possible). Unlike the 7-OH NOI there is NO concentration threshold here — these named substances are controlled outright. Confirm the exact companion docket number when the Federal Register posts on 7/6/2026.
• 2026-11-13 · Federal · DEA to replace pseudoindoxyl Schedule I order with a threshold order (re-notice) (DEA-1570 / FR 2026-20943)
  On or after Nov 13, 2026 DEA intends to withdraw the Aug 26 order (FR 2026-17429) and place pseudoindoxyl in Schedule I only above a threshold: more than 1 mg/g or 1 mg/mL alone or combined with 7-OH, or mitragynine under 100 times the pseudoindoxyl or combined amount. Until then it stays Schedule I at any amount. MGM-15 and MGM-16 stay Schedule I unchanged (FR 2026-20942).
