The United States Postal Service is scheduled to issue its Know the Facts About Fentanyl semipostal stamp on 6 October 2026 at the National Institutes of Health campus in Bethesda, Maryland. The stamp combines ordinary First-Class Mail postal validity with an additional fundraising component for the National Institute on Drug Abuse. Its purpose is to support research and public awareness connected with the overdose epidemic while presenting a message of knowledge, protection, hope, healing and recovery.

The first-day ceremony is set for 11 a.m. Eastern Time in the Masur Auditorium, Building 10 South, on the NIH campus at 9000 Rockville Pike. USPS government relations and public policy vice-president Peter Pastre is listed with NIH director Dr Jay Bhattacharya and National Institute on Drug Abuse director Dr Nora Volkow among the event participants. Because access to the federal campus is controlled, attendees must register in advance and follow the NIH identification and entry arrangements.

The design uses an illustration by Whitney Sherman, adapted for the stamp by USPS art director Antonio Alcalá. It shows a diverse group of people facing the viewer beneath the words “Know the Facts About Fentanyl.” The lower inscription, “Protect Our Loved Ones,” turns the design from a general drug-awareness image into a direct public message. The word “SEMIPOSTAL” identifies the stamp's special fundraising status, distinguishing it from a standard Forever stamp sold only at the prevailing postage value.

The stamp will be sold in panes of twenty for $20. A normal pane of twenty Forever stamps at the current 82-cent First-Class Mail rate has $16.40 in postal value; the higher semipostal price includes an amount above postage and programme costs that is transferred for the designated cause under the applicable federal framework. USPS states that the beneficiary is the National Institute on Drug Abuse, part of the National Institutes of Health, for work advancing research and awareness connected with fentanyl and the continuing overdose crisis.

Semipostal stamps occupy a distinct place in United States philately. They are genuine postage, but their retail price exceeds the underlying postal value so that qualifying net proceeds can support a named public-interest programme. This creates two collecting contexts at once: the stamp belongs in the regular chronological record of United States issues, and it also joins the specialised history of American fundraising stamps. Collectors should not describe the entire $20 pane price as a donation, because the total also covers postal value and authorised costs.

For a basic mint collection, the key object is the full pane of twenty, where the repetition of the design and the semipostal inscriptions remain intact. Postal-history collectors can document ordinary use on First-Class Mail, while first-day specialists can seek Bethesda cancellations associated with the NIH ceremony. A properly serviced first-day cover will link the stamp's fundraising purpose, issuing city and federal research beneficiary more clearly than an unused single removed from its pane.

The location gives the issue unusual institutional precision. Bethesda is not simply a convenient ceremony city: NIH is the federal biomedical-research agency, and the National Institute on Drug Abuse is the organisation designated to receive the funds generated by the semipostal programme. Holding the first-day event on the NIH campus directly connects the stamp with the research body it is intended to support. This relationship is part of the issue's postal history and should be retained in catalogue notes and exhibit descriptions.

USPS announced the stamp in advance on 8 September, but 6 October is its scheduled first day as a current postal product. The date therefore marks the transition from advance announcement to active issue-day material. The Bethesda event occurs later in the American day, and collectors seeking ceremony material sh
