In a fight, can you apply poison to an ally's blade? I can't find anything prohibiting it (and think it would be a pretty neat buff style for an alchemist).
Related question, if you apply poison to a weapon, does it stay on the weapon until a strike is made with that weapon, allowing a character to walk around with pre-poisoned arrows/blades?
Sorry if these have obvious answers, some of the alchemy and poison rules are all over the place and I want to be sure I know how applying poisons work before making a poisoner.

Nor can I.

Yes, but note it goes away whether the strike is successful or not.
Injury
An injury poison activates when applied to a weapon, and it affects the target of the first Strike made using the poisoned weapon. If that Strike is a success or a critical success and deals piercing or slashing damage, the target must attempt a saving throw against the poison. If the Strike is a failure or a critical failure, or if it fails to deal slashing or piercing damage for some other reason, the poison is spent but the target is unaffected.
