Vaping is legal in Italy but since beginning this year, heavy (50+%) taxes got slammed on anything vaping ( hardware , liquids ). Least the Italian gubmint didn't lie about it: None of this 'protect the children' or 'uuhh, it's so dangerous' crap. They were pretty straightforward thar vaping was putting a dent in the rake from tobacco taxes.
So unless u wanna pay through your nose by stocking up locally, bring enough to last you through your stay.
No idea how they're handling things brought in from outside for personal use... As it hasn't really been thought through by the gubmint there, I recommend to leave the expensive hi-end gear stateside. Just so that you're on the safe side should customs get any funny ideas.
'sides, these small ego type thingies do have a habit of sliding in between the clothing ... elusive l'il buggers ...
