So far, two different sets of drinking rules have appeared on the SWRPG mailing list. I've listed both of them below, side-by-side so you can compare them easily and decide which one you like best for use in your game. Alcoholic drinks are rated with a "damage code" like weapons and damage is rolled according to normal game mechanics. Qualls has provided an extensive list of drinks and damage codes for use with either set of rules below.
Amount of damage equals: how much the drink damage > the character's Stamina or STR roll. The character may roll using Stamina if s/he has that skill, otherwise use STR.
I seem to recall reading somewhere that while a certain drink was alright for a particular species, it was lethal to others. How do you work damage codes on say, a human drinking a gamorrean drink?
The damage codes are constant. Just like blasters or chairlegs, drinks
inflict the same amount of damage on all characters, unless otherwise
specifically noted in Special Abilities. That isn't to say, though, a
drink can't affect different species in different ways. If a drink
lethally interacts with the enzymes of a certain species, note it in the
drink's Special Abilities and it becomes law. Typically, though, that
humanoids' anatomies are usually very similiar. The reason why a Gamorean
drink is stronger than a human drink is simply because Gamoreans on
average are stronger.
thanks to MikeK for answering that one...
