If guns sitting on a table dont kill people does fentanyl sitting on a table kill people?

As always, you have no clue how reality works.

If fentanyl is added to other substances that people ingest, it often kills them. And they might not ever realize what happened.

If a firearm was ground up and added to food or drugs, it would become what's commonly known as an "iron supplement."

You're welcome.

fentanyl is a legal drug, when misused causes death.
You're welcome
