1. Supply Shock from Biden-Era US-China Cooperation
Decline attributed to China's 2023 crackdown on fentanyl precursors, enabled by Biden administration diplomacy.
defrost: "Biden era cooperation with China on the issue was at the heart of this... Was going well (as per the paper) until US / China relations went in the toilet."
Analemma_: "in 2023 China cracked down on it, and supplies dried up."
2. Dealers Reducing Potency to Protect Customers
Dealers intentionally diluted fentanyl to avoid ODs, killing fewer repeat buyers and stabilizing supply chains.
bsder: "Illegal drug suppliers don't make money by killing their customers. Consequently, they finally got control over the potency throughout their supply chain."
cyberax: "reducing the amount of fentanyl per pill results in a better safety margin."
3. Depletion of Vulnerable Users
High OD rates killed off reckless addicts faster than new ones emerged, shrinking the user base.
pengaru: "Just a different form of supply shock - to the supply of users... those using fent on the streets are not long for this world."
hattmall: "Killing addicts more quickly than creating new ones would indeed eventually lead to a decrease."
4. Harm Reduction via Narcan and Safer Use
Widespread Narcan access and users learning safer dosing/consumption reduced fatalities.
cyberax: "There's just more free Narcan (naloxone)."
mythrwy: "survivors have become more educated on how to use without dying."
