Which is worse of health: coffe addict or smoke addict?

A smoking addiction is worse.

1-2 cups of coffee a day is fine and certainly not an addiction.  Cigarettes will kill you.

That's not a coffee addict lol. Both can be dangerous if you overdue them

Coffee can be bad for the heart rate if overdone... but smoking causes lung cancer and yellowing of nails, teeth...

Coffee can be had in moderation. 

Smoking in all of its forms contains addictive chemicals and the big companies had to admit it, pay out billions, and are still thriving because of it.

My stepdad drinks coffee like crazy... even late sometimes... but sleeps well...

It just really depends.

Caffeine is regarded as a "drug" by some, though... but cancers linked to it (if there even are any and I'm not sure) are definitely not at the level of smoking/tobacco. 

A smoking addiction would be deadly.  Drinking 1 - 2 coffees a day is not deadly and I wouldn't call it an addiction either unless you are also consuming lots of other things like cola and tea which also have caffeine.  

You won't die from drinking coffee.  The same can't be said about cigarettes.
