It's accidental - fentanyl is active in the microgram range, so the tiniest mistake can be fatal. Common warning about fentanyl: > This substance is extraordinarily potent (i.e. active in the microgram range), to the point that the pure powder can result in a fatal overdose if spilled on one's skin. [...] It is strongly encouraged to wear gloves while handling, use volumetric dosing combined with a milligram scale https://psychonautwiki.org/wiki/Fentanyl https://psychonautwiki.org/wiki/Fentanyl (notably heroin doesn't have the same warning)
