I read an article a few months ago about how the import restrictions (or maybe that there's just fewer international shipments) from Covid were making it harder to smuggle things into the US. I wonder if that is having an impact on the quality of street drugs and causing overdoses. If fentanyl is so much more compact than heroin, I wouldn't be surprised if drug smugglers prioritized fentanyl given the limited quantities that can be smuggled. That would make street doses far more dangerous.
