Drugs, Synthetic or Analogue - As introduced, removes the limitation that a person who is experiencing a drug overdose only has immunity from being arrested, charged, or prosecuted on the first drug overdose. - Amends TCA Title 50; Title 53; Title 63 and Title 68.

HB 464 removes a restriction in Tennessee law that previously limited legal immunity from arrest or prosecution for drug overdose to only the first overdose. The bill amends Tennessee Code Sections 63-1-156 and related provisions to ensure immunity applies to all subsequent overdoses when seeking help. This directly affects individuals experiencing drug overdoses who contact emergency services, as they will no longer face legal consequences for prior overdoses. The key change eliminates the "first overdose" limitation, providing consistent legal protection regardless of how many overdoses occur. The bill takes effect July 1, 2025.
