San Francisco's First MGM-15 Death Puts a Gas-Station Opioid on the Record
San Francisco recorded its first fatal overdose tied to MGM-15, a kratom-derived opioid sold in convenience stores. Naloxone is the guidance. The bigger problem is what the label says.
The House Voted to Schedule Xylazine. The Drug That Replaced It Sends People to the ICU.
Nine states scheduled xylazine and saw medetomidine reports climb. As Congress weighs a federal xylazine ban, hospitals report ICU-level withdrawal and people who use say the sedation can't be fought. What helps now.
The DEA Finally Drew a Line Between Kratom Leaf and 7-OH. The Gas-Station Shelf Is About to Feel It.
DEA's October notice would place 7-OH and MGPI in Schedule I above an HHS-recommended concentration threshold, separating enhanced products from botanical kratom.
Through eight lenses
Science
Alpha-2 agonists (xylazine, medetomidine — veterinary sedatives), nitazenes as μ-opioid agonists (synthesized in 1950s, never approved, re-emerging), kratom mitragynine partial μ-agonist + alpha-2, tianeptine atypical antidepressant with opioid activity at high doses.
Biology
Xylazine causes necrotic skin ulcers characteristic + prolonged sedation not reversed by naloxone; nitazenes act like high-potency fentanyl analogs (naloxone-reversible, higher dosing may be needed); kratom has its own withdrawal syndrome; tianeptine "gas station heroin" causing emergency-dept surges.
Psychology
Dependence patterns mirror the parent class but often with gaps in clinical recognition.
Policy
DEA scheduling scramble — xylazine FDA-declared emerging threat, nitazene analogs being scheduled piecemeal, kratom DEA deferred twice, tianeptine state-by-state patchwork.

Trends
Xylazine now in 48 states' supply; medetomidine identified in Chicago-area 2024; kratom retail boom.
Treatment
Xylazine wound care + opioid co-treatment; nitazene overdose reversal with naloxone; kratom dependence — buprenorphine effective; tianeptine dependence — like opioids.

Harm Reduction
Test strips for xylazine + nitazenes (where available), stay with person during prolonged sedation, don't use alone, high-dose naloxone availability.
