Nitazenes and xylazine: what’s behind the rise of dangerous synthetic drugs?

Social affairs correspondent Robert Booth tells Madeleine Finlay
why a class of synthetic opioids called nitazenes, first developed
in the 1950s, is leading to a worrying number of fatal overdoses in

Joseph D’Orazio about a tranquilliser called xylazine that has been
showing up in alarming volumes in the US illegal drug supply and is
now starting to appear in toxicology reports in the UK. Help
