Relating to measures to prevent and respond to opioid-related drug overdoses, including policies and training regarding the use of opioid antagonists, at student residences on campuses of public institutions of higher education; providing immunity.

SB 556 requires public Texas universities with on-campus student housing to adopt policies ensuring opioid antagonists (like naloxone) are available and properly stored in residence halls. It mandates training for resident advisors to administer these drugs during suspected opioid overdoses and sets rules for inventory checks and secure storage. The bill also requires universities to include these policies in student handbooks and post them online. This directly affects all public institutions of higher education operating student residences in Texas. The policy aims to improve immediate response to overdoses on campus without specifying enforcement or outcome expectations.
