I'm no lawyer, but I believe that the Trading with the Enemy Act makes it not just illegal to bring Cuban cigars into the US, but also to spend any non-exempted money on any purchases that would help Cuba. My understanding is, then, that it is illegal for a US citizen to purchase Cuban cigars anywhere in the world, even if they do not enter the US. I believe the fines are even steeper since GW Bush...like $10,000. So, I will assume that someone gave you these as a gift and that you smoked them outside the US, not having paid for them
