This is an incredible opportunity to save lives. You need to familiarize yourself with accidental opioid overdose deaths. Most people who die from a fentanyl overdose were not intending to ingest fentanyl. Fentanyl is often used to boost the strength of more expensive opioids sold on the street. Fentanyl is very cheap to produce compared to heroin or whatever is the flavor of the month pressed pill. People die because the recreational dose for an opioid like heroin isn't many orders of magnitude away from the LD50
"Once feared, illicit fentanyl is now a drug of choice for many opioid users: People with opioid-use disorder are increasingly seeking out illicit fentanyl, often smoking it."
(I really do know that everything you read in popular media about drug use in general, and opioid use specifically, cannot necesssarily be trusted. But my understanding from several sources is that this is so. The fact that fentanyl is cheaper for the effect is a reason a user might choose it too, or it may simply be what is available, or affordable)
Whether users are intentionally seeking and/or aware of getting fentanyl or not, I am saying that the consequences of making someone's dose not have the effect they are looking for can often be that they take more (getting more of all of the substances that were in the dose, known or unknown), or that they switch to an alternate supply/substance. Either of which can have very dangerous outcomes.
I won't tell you what you need to familiarize yourself with, or assume I know what you are or are not familiar with.
