CDC data show synthetic‑opioid deaths didn’t just rise—they spread. From 2018 to 2019, the West had the largest relative jump in fentanyl‑class overdose death rates (up 67.9%), reversing earlier eastern concentration. This westward diffusion coincided with rising polysubstance involvement.

Both pieces document how regional conflicts and supply‑side shifts reorient global drug flows; the article describes Syria evolving into a production/transit hub (Captagon) whose shipments now surface in European ports, mirroring the earlier westward movement of fentanyl as an example of how illicit supply adapts to markets and geopolitics.

The Wikipedia article cites CDC counts showing synthetic opioids (primarily fentanyl) were involved in roughly 70,600 deaths in 2021 (about 64% of that year's overdoses), which directly supports the claim that fentanyl became the dominant driver of the overdose crisis and explains geographic spread and timing referenced by the existing idea.

Although the USAFacts piece is national, it notes illicit production and smuggling across the US–Mexico border—connecting to analyses that document geographic diffusion of fentanyl (e.g., westward spread by 2019) and the role of cross‑border supply chains.

CDC MMWR: “the largest relative increase in the synthetic opioid‑involved death rate occurred in the West (67.9%)” during 2018–2019.

The report flags synthetic opioids (e.g., illicit fentanyl) as the main driver of the 2015–2016 uptick, providing antecedent national evidence that supports later analyses describing geographic diffusion (including westward spread) of fentanyl‑linked mortality.
