If a dot of fentanyl can kill you, how do we use it in medicine, and how do people get addicted?

Question

I’ve always heard that a singular dot of fentanyl can kill you. Yet we use it medically, for pain relief. And many people are addicted to it but stay alive while using. Is there like a different method of using it? How do people use it and not die?

Answer 1

I used to use fentanyl patches for my bad back and they hardly did anything. No more refills. The doctor says it’s now only prescribed for cancer patients. So now they prescribe me morphine. Yes, it does stop the pain for quite a while.
