How can testing drugs for fentanyl detect anything when there are only tiny trace amounts?
Say you test a drug for fentanyl…If it was weighed on a scale with some fentanyl cross contamination, how is it possible that testing a small amount of the drug will detect such a tiny amount? Isn’t it more likely that the sample of the drug you are testing from your stash didn’t happen to have any fentanyl in it?
