How long do you allow poison to be on a weapon and affect the target?
I was thinking on having some rules based on the type of poison, ie paste, oil, liquid, powder and I but there is some type I do not know about (without getting into compound states like gels, aerosols, etc).
The base rule would be a poison based on a level vs save vs persons con (Con stat/10 +1 or -1 per racial stat bonus+ other bonus) (But I might up that base to be 10 or Con stat/5 + etc.)
Then the substance would have a base attack level that would either decrease or receive penalties for time in use or out in the air etc.
Do people have numbers that they use in their game?
