This bill directs the Commandant of the Coast Guard to update its policy within one year to ensure the use of medication, such as naloxone , for treating drug overdoses, including those involving opioids and fentanyl. The updated policy must mandate that naloxone or similar medication is available for Coast Guard members on all installations and in every operational environment, with provisions for multi-facility installations. The legislation also requires the Coast Guard to participate in a national drug tracking system and for the relevant Secretaries to finalize a memorandum of understanding to facilitate this access within one year. Within two years, the Commandant must brief congressional committees on the policy's implementation, the prevalence of illegal fentanyl and controlled substances within the Coast Guard over the past five years, and the status of the tracking system and MOU. This briefing will also review instances where naloxone was used to treat overdoses. Finally, the bill amends federal law (46 U.S.C. 70503(a)) to clarify and strengthen prohibitions against manufacturing, distributing, or possessing with intent to distribute controlled substances on board covered vessels. All requirements under this act must adhere to applicable privacy laws, including the Privacy Act and HIPAA regulations.
