The title is probably sufficient enough to convey the question, but just to be clear I'll explain.
Do you think touch injection could apply an ingested type poison to a creature? It seems like the answer (RAW) leans towards no, but potions can be administered via touch injection and they're normally ingested, so by association it would make sense for poisons to work too.
By the same logic of saying no to ingested poisons, inhaled wouldn't apply either(because it's not being inhaled), or possibly even injury, where one could plausibly rule that you need to take damage for it to apply(which I don't think is true RAW, but it kinda makes sense to distinguish it from contact in some way). This sort of argument seems pretty convincing to say that ingested would apply via touch injection since it would otherwise make touch injection rather useless for administering poisons.

On a side note and somewhat related note, Do you think that a poison converted via Poison Conversion discovery will have it's onset and/or frequency changed to be appropriate to it's type? i.e. should an ingested poison converted to an inhaled poison still have a 10 minute onset and minutes frequency?
It seems rather strange to have the frequency and onset remain unchanged, and also maybe makes the discovery a bit weak.
