Porcupines don't really attack. They generally only try to get away. Sometimes, if a human stumbles across them or messes with them, they can end up with quills stuck in them.

humans are a threat to all animal life.
The answer is NO A porcupine has no mechanism for launching it's quills at victims. The porcupine will shake it's body making the hollow quills rattle as a threat, and in the process some of the quills may shake loose, but this is not the same as throwing them. A porcupine will reverse towards the threat (with some considerable speed) and if the threat does not retreat quickly it may find itself with a large number of quills embedded in it's body. The quills are not tipped with poison but have a large number of bacteria living on them that can lead to severe infection if not treated quickly.
