Custom Poisons by Philip Black begins here.
"This is an addon for the Alchemy Poison & Item Crafting Engine by Philip Black is just a handy script allowing you to set up some very general non-item-specific effects for the three levels of poison that it adds to the game. The idea of this addon is for you to edit the script yourself in order to add your own optional poison effects. If you do not edit this script because you want to add poison effects on an item-by-item basis, or you don't or you don't want to add poison to your game, then you might want to avoid using this extension. As supplied, the only effect that eating poison will have (when using this script) is a message telling them they have, unless they eat Deadly Poison, which is instantly lethal. You do not need this script to add poison effects to your game as the Alchemy Engine already allows you to tag items as Poison Tainted, Poisonous, VERY poisonous, DEADLY poisonous, alcoholic, slightly alcoholic, and safe, as well as adding the 'toxic tested' flag that makes it easy to add poison testers to your game. If you do not want poison in your game, all you have to do is avoid telling the Alchemy Engine that anything is poisonous."
