Carfentanil is probably more potent then LSD, here is a lethal dose:

https://mediad.publicbroadcasting.net/p/wosu2/files/styles/x...

"For pain relief, a unit of carfentanil is one hundred times as potent as the fentanyl, five thousand times as potent as heroin, and ten thousand times as potent as morphine, despite having only 14 to 135 times the affinity for the mu receptor."

That carfentanil looks like about a milligram, but impossible to say without knowing its density.

"The New York Times warns that a particle of carfentanil as small as a grain of salt or piece of dust can be deadly and that the drug is lethal in a dose as minuscule as 0.02 milligrams. "

so about 1/50th of a milligram is deadly... not sure what's the maximum dose before it kills you

1.0 µg of carfentanil is equivalent to 10 mg of morphine
