Synthetic Kratom Makers Sidestepped Florida's 7-OH Ban With MGM-15, Prompting a Death

Why it matters

A Hernando County man died after ingesting MGM-15 — a synthetic kratom derivative created specifically to skirt Florida's emergency ban on 7-OH — illustrating how quickly chemical manufacturers can reformulate products after a regulatory action and why substance-specific bans face structural limits.

The big picture

Florida banned 7-hydroxymitragynine as a Schedule I narcotic in June 2025. Within months, chemists had created MGM-15, a structurally similar synthetic compound designed to retain the drug's effects while evading the law. The DEA's July 2026 federal action now targets MGM-15 and two related compounds alongside 7-OH. Poison control data show a 13-fold increase in kratom-related calls since 2015, reaching 3,434 reports in 2025.

Key findings

• Florida banned 7-OH in June 2025; synthetic manufacturers responded by introducing MGM-15
• Hernando County resident Michael Walker died from MGM-15 ingestion eleven months after the 7-OH ban
• Walker's toxicology prompted Florida to expand its emergency rule to cover MGM-15 and two other derivatives
• U.S. Poison Control Centers received 3,434 kratom-related reports in 2025, up from 258 in 2015
• 7-OH is reported to be up to 13 times more potent than hospital morphine
• FDA Commissioner Makary compared the synthetic kratom crisis to the early fentanyl surge, warning regulators not to fall behind again

What they say

"7-OH binds to the mu-receptor, which means scientifically, by definition, it is an opioid... We have to be proximate to this. We got burned with fentanyl and prescription drugs; we cannot be behind the 8 ball again," said FDA Commissioner Dr. Marty Makary.

Bottom line

Florida's 7-OH ban created a direct chemical evasion that killed at least one person within a year — and the same loophole pattern now drives the federal push to schedule MGM-15 and related compounds.
