The House has passed bipartisan legislation aimed at cracking down on fentanyl. The bill approved Thursday permanently reclassifies analogs of the synthetic opioid fentanyl as Schedule I drugs, making it easier to prosecute drug traffickers for their possession.

The House overwhelmingly passed bipartisan legislation Thursday that would solidify federal policies cracking down on the synthetic opioid fentanyl and its analogs in a bid by lawmakers to combat the nation's opioid epidemic.

The Republican-sponsored HALT Fentanyl Act, a bill cracking down on fentanyl and related substances, passed the House in a bipartisan 321-104 vote Thursday.
