I have made brand new Alcohol & Tobacco Expansion -document (or revised the old one I had). It features new consume alcohol rules for the each of the Warhammer Fantasy Roleplay editions (WFRP3, WFRP2, WFRP1). Also the rules about the famous alcohols and tobacco, found from the Old World, use universal rules.
Consume Alcohol rules should be easy and fast. Idea is to give some funny new ideas/rules to this type of "social encounters". Then there is hangover rules, lists of alcohols and tobacco products. For WFRP3 there is number of new cards, including tracking card for the consume alcohol and also to the hangover. New cards also feature brand new mutation...
You can find all these from my site: Kalevala Hammer - Rule Expansions
Have fun using these with your players.
