Health Canada flags U-47700 in hopes of staving off latest opioid threat
OTTAWA — The federal government is looking to stave off the threat of a powerful new street drug its users have christened “grey death.”
Health Canada is seeking stakeholder comments on a proposal to add a deadly new compound, known formally as U-47700, to the Controlled Drugs and Substances Act.
A posting in the Canada Gazette says U-47700 is being used by drug manufacturers in counterfeit prescription medications, as well as in other illicit drug mixtures such as cocaine and heroin.
“Grey death” — named for its resemblance to concrete powder — is a combination of U-47700 and opioids like heroin, fentanyl and carfentanil, an elephant sedative.
