A study in the Journal of Studies on Alcohol and Drugs says what you already knew - if you get drunk and pass out, you are more likely to die in a fire you could easily have escaped, if you weren't hammered drunk and sleeping on the floor.

Bonus: they manage to take shots at smokers too. 

The researchers' recommendation; have a designated house sitter.  Yes, if you are going to pass out drunk, have someone sober staying at the house. Because all sober people want to watch you get smashed.

In recent U.S. studies, anywhere from 40% to 55% of people who died in fires were intoxicated, based on blood alcohol tests.  Alcohol kills.  Kids, stay in school.
