WASHINGTON (WJHL) — The U.S. House passed a bill by Southwest Virginia Congressman Morgan Griffith to classify fentanyl-related substances as Schedule I substances.

The HALT Fentanyl Act was passed Thursday in a 312-108 vote.

Griffith says his legislation would end a loophole that drug traffickers are exploiting by classifying fentanyl analogues as Schedule I drugs.

“The HALT Fentanyl Act highlights House Republicans’ commitment to tackling deadly fentanyl-related substances and saving lives,” Griffith said in a release. “I appreciate Speaker Johnson, Leader Scalise, Whip Emmer and Chairwoman McClain for supporting this critical legislation. I commend my dedicated colleague, Congressman Latta, for his contributions to advance this critical legislation. The American people, including those in Appalachia, deserve nothing less than safe neighborhoods and safe streets.”

Last week, Griffith told News Channel 11 that the legislation would not affect the use of medicinal fentanyl nor impact fentanyl-related research.

The bill still needs Senate approval.
