You wouldn't know it tbh. I went to a couple of music events in Spain last year and sadly the most notable thing was how long it took to shift my passive smokers cough and get the smell out of my hair . Have noticed people smoking in restaurants too.
I'm not sure about Italy! A lot of venues I visit are of dubious legality anyway so a few people smoking inside is the least of their problems if the police want to give them any trouble.
Smoking inside. Currently sat in a van in an alleyway in Rome to avoid being in a venue with roughly 100 chain smoking Italians.
