You'd have to come across one hell of an overzealous cigar aficionado cop to get arrested for it though. It's a supplemental crime; an offense they'll nail you with to increase the jail time of another offense. Most cops I've ever met would probably steal them, and let me off the hook.
As far as the sellers of Cuban cigars... I imagine that's a different story.
Mental note - do not sell Cubans to Americans no matter how much profit is involved...
