Schedules of Controlled Substances: Placement of MDMB-4en-PINACA in Schedule I

Detected July 16, 2026 · in Pharmacy & Controlled Substances

DEA places MDMB-4en-PINACA into Schedule I, making it illegal to possess, handle, or dispense without DEA registration.

Aforeworn detected this change in the Pharmacy & Controlled Substances space on July 16, 2026 and published this briefing so affected operators are forewarned rather than caught off guard. It is rated High urgency. All pharmacies handling controlled substances should confirm how it applies to their specific situation before acting. There is a time constraint attached: Effective immediately upon publication (April 24, 2026).. Acting after that point can mean penalties, a lapsed licence, or lost eligibility — exactly the kind of surprise Aforeworn exists to prevent. Aforeworn monitors Pharmacy & Controlled Substances continuously and turns every detected change into a plain-English briefing like this one, so you always know first. Forewarned is forearmed.
