The answer to number 1 is no, the more important thing is, why are you letting your friend smoke dog rockets, get him some real cigars, and then maybe you'll have reason to worry. But honestly, you're going to europe and worried about crappy gas station cigars being confiscated? If anything, I hope those pieces of crap get confiscated, then while in Europe you find some real cigars, cubans to be specific and smoke and enjoy those.
