Revise laws related to state purchase of opioid antagonists

This bill prohibits Montana state agencies from using state or federal funds to purchase opioid overdose reversal drugs from companies that have previously settled with the state over opioid-related misconduct. The law applies to all purchases made after June 30, 2025, with exceptions for existing contracts signed before July 1, 2025, which must be completed but cannot be renewed. Companies that agreed to supply these medications as part of a settlement before September 1, 2024, must continue providing them until their contractual obligations are fulfilled. The measure takes effect immediately upon passage and approval, directing state procurement officials to avoid purchasing from specified entities going forward.
