If I were to travel over seas, Europe for example. And made some tobacco purchases, say a pound or two of a couple varieties. Would there be a customs issue coming back into the US? I had a cousin travel to Europe somewhere a while back, he was able to purchase a box of cuban cigars and bring them back. He said ge just had to open the box and carry one in his pocket, so as to show that they were not going to be sold again in the US. Anyways, would there be an issue bringing back "large" quantities of tobacco?
