Who drinks the most coffee and smokes the most cigarettes? Not your average American, says a new study. It's those recovering from alcoholism who drink more than four cups of coffee per day and smoke much more than their non-recovering counterparts.

Why the fondness for coffee and cigarettes? Study participants said they rely on coffee to wake them up and cigarettes to help them deal with negative moods.

Researchers say they are looking at whether changes in coffee and smoking habits are predictive of alcoholics' ability to stay in recovery. Initially, they think coffee may actually aid in recovery while smoking may hinder it.
