Tobacco: $0. I tried it out when I was a wee lad and aside from a few clove cigarettes, I never got into it.
Alcolhol: I go through a six pack of micro-brew a week, so about $25-$30 a month on beer (in fact, I’m enjoying a nice New Glarus Fat Squirrel as I type this. Mmmmmm) and maybe one bottle of wine or so a month, so maybe another $15-$20.
