A new wave of synthetic drugs is sweeping across the United States, raising fear of a worsening drug crisis.
Earlier this year, President Donald Trump pledged a crackdown on drug cartels, proscribing many as terrorist organisations.
Drug overdose deaths have fallen from a peak of around 110,000 in 2022, down to roughly 70,000 last year.
