White House cites 'emerging threat' of 'tranq,' tranq-laced fentanyl

The White House is launching a campaign against the "emerging threat" of xylazine-laced fentanyl, hoping to slow its spread domestically and disrupt supply lines into the country

"This designation comes after careful review of the impact of xylazine on the opioid crisis, including its growing role in overdose deaths in every region of the United States," the White House said in a statement.

Xylazine is a common veterinary drug, used as an animal tranquilizer and pain reliever. But it has now become a favorite of drug dealers looking to cut costs.
