I've just been reading something on Threads about someone dying from a Fentanyl OD. I also read Demon Copperhead recently (brilliant novel) which is about the Fentanyl crisis.
Why is this such an issue in the US but not (as far as I know) in Europe? Use of other drugs such as heroin seem to be roughly the same across the US and other parts of the world. So why is Fentanyl different?
Also, does anyone have a recommendation for a documentary about the issue? I'm interested in learning more.
