Would require the Coast Guard to make the opioid-reversal drug naloxone available on all its installations and in every operational environment, and to join a Department of Defense system that tracks naloxone distribution and illegal controlled-substance use among service members.

The bill would also close a legal gap by clarifying that drug-trafficking laws apply when controlled substances are placed on a vessel without the crew's knowledge — such as on unmanned or remotely operated vessels.

What this bill would do

What it would do

The bill would direct the Commandant of the Coast Guard to update overdose-medication policy within one year of enactment, specifically requiring naloxone or a similar opioid-reversal drug to be available on every Coast Guard installation and in each operational environment. The bill would also require the Coast Guard to join the Department of Defense tracking system — created by the National Defense Authorization Act for Fiscal Year 2024 — that monitors naloxone distribution and illegal use of fentanyl and other controlled substances. A memorandum of understanding between the Coast Guard's parent department and the Defense Department would need to be finalized to enable that access. The Commandant would also brief relevant congressional committees within two years on overdose medication use, opioid prevalence, and substance-abuse mitigation efforts.

Separately, the bill would amend the federal vessel drug-trafficking statute to make clear that prohibitions on manufacturing or distributing controlled substances apply when drugs are intentionally placed on board a vessel — including by someone other than the crew, or on an unmanned vessel. The bill does not itself appropriate funds, and the naloxone availability requirement includes a rule of construction allowing a single facility within a multi-facility installation to satisfy the requirement if access is ensured at all times.

Key provisions

  1. 1Would amend 46 U.S.C. § 70503(a) to extend vessel drug-trafficking prohibitions to cases where controlled substances are intentionally placed on board a vessel, including without the crew's knowledge or on unmanned vessels.Sec. 1
  2. 2Would require the Commandant to update Coast Guard overdose-medication policy within one year to mandate naloxone availability on all installations and in every operational environment.Sec. 2(a)-(b)
  3. 3Would require the Coast Guard to participate in the DoD tracking system for naloxone distribution and illegal fentanyl and controlled-substance use within one year.Sec. 2(c)
  4. 4Would require the Coast Guard's parent department and the Defense Department to finalize a memorandum of understanding to enable Coast Guard access to the DoD tracking system.Sec. 2(d)
  5. 5Would require the Commandant to brief Congress within two years on opioid and overdose-medication use at Coast Guard facilities, policy implementation progress, and substance-abuse mitigation efforts.Sec. 2(e)

Who would be affected

Active-duty and civilian members of the Coast Guard who work on installations or in operational settings, Coast Guard command and medical personnel who would implement the updated policy, the Department of Defense (which operates the shared tracking system), and individuals apprehended under the clarified vessel drug-trafficking statute — including cases involving unmanned or remotely operated vessels.

Why it matters

If enacted, Coast Guard personnel at every installation and in field operations would have on-hand access to naloxone, potentially saving lives in overdose emergencies. The tracking system integration would give the service data on fentanyl exposure trends alongside other military branches. The vessel statute clarification removes an ambiguity that could affect prosecutions of drug smuggling on crewless or drone vessels.

What would change

Changes to existing law

Amends 46 U.S.C. § 70503(a) (Sec. 1)

Extends vessel controlled-substance prohibitions to cover intentional placement of drugs on board a vessel, even without crew knowledge or on unmanned vessels.

Amends National Defense Authorization Act for Fiscal Year 2024, section 706 (10 U.S.C. 1090 note) (Sec. 2(c)-(d))

Requires Coast Guard to participate in and access the DoD tracking system established under this provision.

Funding and costs

Congressional Budget Office estimate

CBO estimates H.R. 2351 would cost $1 million over the 2025–2030 period, subject to appropriations, with no effect on direct spending, revenues, or the deficit.

CBO estimates that H.R. 2351 would have no effect on direct (mandatory) spending or revenues, leaving the deficit unchanged over the 2025–2035 period. The bill's costs — estimated at $1 million over 2025–2030 — stem from discretionary (appropriated) spending needed to supply naloxone and similar overdose medications to additional Coast Guard facilities and to maintain a tracking and reporting system. CBO found no intergovernmental or private-sector mandates in the bill.

How implementation would work

The Commandant would have one year to revise written policy and arrange naloxone supplies across all installations and operational units, with a compliance rule allowing a single stocked facility to cover an entire multi-unit installation if access is guaranteed around the clock. In parallel, the Coast Guard's parent department and the Defense Department must finalize a memorandum of understanding — also within one year — to enable Coast Guard access to the DoD tracking system. Within two years, the Commandant must brief the House Transportation and Infrastructure Committee and Senate Commerce Committee, covering policy progress, five years of controlled-substance prevalence data, and the MOU status. All data collection must comply with the Privacy Act and HIPAA.

This bill requires the Coast Guard to provide access to naloxone (a medication to reverse opioid overdoses) at its facilities, track distribution of the medication, and monitor the illegal use of of controlled substances.

The bill directs the Coast Guard to update its policy regarding the use of medication to treat drug overdoses to require naloxone or a similar medication to be made available to members on all Coast Guard installations and in each operational environment.

Further, the Coast Guard must participate in the Department of Defense (DOD) tracking system for naloxone distribution and the illegal use of fentanyl and other controlled substances. (The National Defense Authorization Act for Fiscal Year 2024 directed DOD to establish the tracking system.) The bill requires the Coast Guard to finalize a memorandum of understanding with DOD to facilitate Coast Guard access to the tracking system.

The bill also specifies that laws that prohibit manufacturing or distributing controlled substances on vessels apply when controlled substances are intentionally or knowingly placed or caused to be placed on board a vessel (e.g., without the crew's knowledge or on board an unmanned vessel).

Further, the bill requires the Coast Guard to brief Congress within two years after the bill's enactment about the use of opioids and overdose medication at Coast Guard facilities by members and personnel. The briefing must describe the Coast Guard's progress in implementing its updated policy, the prevalence and incidence of the illegal use of controlled substances, and its processes to mitigate substance abuse.
