FWIW since I started referring to this as poisonings (instead of overdoses) I've found folks to be much more amenable to conversation. Nobody likes the idea of the wicked poisoning the vulnerable.
How do folks respond when they find out many addicts clearly choose to take the "poison" for more complex highs? despite knowing the risk, despite cheaper priced "non-poison" offerings.
The dosage makes it poison, so it is an overdose if a properdose was sort and personally misjudged.
With nuance, I guess? Depends on the conversation.
I'd say that there's more agreement than disagreement. Here 70% of the overdoses are related to drugs cut with unpredictable levels of fentanyl. I'd say I've seen consensus on that being a "bad thing(tm)", and consensus that the criminals cutting street drugs with fentanyl are "bad guys(tm)".
I guess to your point about junkies making bad decisions, my peer group skews older, we've already said everything we can say about junkies making bad decisions 30+ years ago. It's true, but it makes for stale conversation and seems kind of orthogonal to, or at least adjacent to, the current fentanyl situation.
