Would 7.7 nanograms per milliliter of Fentanyl be fatal?

A concentration of 7.7 nanograms per milliliter of fentanyl is considered potentially dangerous, but whether it is fatal depends on several factors, including the individual's tolerance to opioids, overall health, and the presence of other substances. For many individuals, especially those without a tolerance to opioids, even a small amount of fentanyl can lead to overdose and death. It's important to monitor and seek immediate medical help if fentanyl exposure or overdose is suspected.
