Anecdotally I think Europeans are more likely to self medicate with alcohol and cigarettes rather than prescription pills which are more common in the USA.

In my experience the culture around having a few drinks after work and even having the occasional cigarette is far more relaxed in the European countries I've been to than just about anywhere in the USA.

But as I've said, I have zero evidence that any of this is even true - just my observations however well travelled I am.
