Smoking was (and in many places still is) a social, cultural and periodic habit. Does it mean that, in such conditions, it shall not be considered as an addiction?

I drink coffee as a habit. But I'm aware that somewhat I have that addiction. Actually the difference between habit and addiction seems to be the side effects. By default habits tend to have them positive while addiction have them negative, socially or neurochemically speaking. That's why I don't think driving is an addiction. Not because I'm not aware of its severe side effects, but simply because there is no possibility of having a society, where almost 90% of its elements are addicted, in the same sense smoking was not considered an addiction in the 1960s, because tobacco was broadly consumed and it was socially (and legally) very well accepted.

The social patterns also seem to mould the definition of addiction.

This sentence proves that you're taking the social definition: I'm not addicted to coffee because such addiction does a disservice to those struggling with cocaine.
