How many people could the fentanyl at an ordinary hospital kill?
By this metric? Enough to kill every person who has ever stepped through the door of one.
LOL. Not nearly that many.
Typical dose of fentanyl in an adult is 75 to 100 MICRO GRAMS
10 kg ( about what they seized ) is 10,000,000,000 micrograms
Thats about 1,000,000 standard doses.
