Fentanyl overdoses have emerged as the leading cause of death for young Americans ages 18 to 45, but some state legislatures are pushing back against health measures designed to help people survive opioid addiction.

This week, lawmakers in Pennsylvania's state Senate voted heavily in favor of a ban on supervised drug injection sites, with 22 Democrats supporting the measure. It hasn't yet been approved by the state House.
