Additional side effect of smoking:

[theweaselking]

It blunts the effects of caffeine. As in, you need 3-4 times as much caffeine as a non-smoker to get the same effect. Oh, and it also has the same effect on some antipsychotics - meaning smokers need a much bigger dose, and if you quit smoking while on them you'll be overdosing. And if you start smoking while on them, you'll be underdosing.

It is true that when I smoked I drank more coffee, though I sort of assumed that that was because coffee and cigarettes, they kind of go together.

Alcohol also seemed to have a stronger effect after I quit smoking, but that's anecdotal.

I have always felt that smoking decreased alcohol's effect on me, but never found any science to back that feeling.

Still -- it is consistent. Drink without smoke == (more) caution required.

...this totally explains why I can no longer tolerate as much caffeine. >_<
