A new study examining the drop in opioid overdose deaths suggests the decrease, starting mid-2023, is due to a disruption in the supply chain of fentanyl precursor chemicals from China, which has reduced street drug potency.
The study, published in the journal Science this month, looked at the decline in fatal overdoses tied to synthetic opioids, mainly fentanyl.
