I know that both are very dangerous to my health, but which is more likely to kill me first: drinking alcohol to excess or smoking cigarettes to excess?
drinking is more likely to get you as under its influence, you are more likely to burn the house down, step out in front of a car etc...of course if you smoke as well then you are WAY more likely to burn the house down, ask any fireman.
I agree with 5029.A relative who used to work in the ambulance service said that choking during sleep/unconciousness after a heavy drinking session led to more deaths than you might imagine.
you can die more or less instantly from alcohol poisoning and if you drink sprits it would not take that much for a small person not used to drinking much, more difficult for a fat alcoholic. no such equivalant exists for smoking cigarettes. i don't suggest trying it though.
