How soon after a regurgitation can I handle my snake?

[200xth]

I know the cause, it was just too big

No, it wasn't.

I fed my 74 gram male ball python a 14 gram hopper mouse.

That is well within normal limits. I've fed a 20g mouse to a 69g snake once and it took it fine. You probably should look to other reasons besides size of food for the regurge.
