Rapid Overdose

When it comes to using fentanyl, it only takes a small dose to reach a serious effect. For fentanyl, overdoses occur much more rapidly than other opioids, and the window of time for recovery after an overdose is shorter. For heroin, death proceeding an overdose usually occurs under 3 hours after consumption rather than suddenly. However, death after a fentanyl overdose can occur in under 15 minutes of consumption.
