Before 2004 you could bring back some stuff from Cuba. Then Bush happened. Between 2004 and 2014 any Cuban cigars (or anything at all) in the US were illegal, end of story. If it was a Cuban product of any kind, it could not be anywhere on US soil. Period. Since 2014 it's back to the old $100, $400 etc.
Now, if you see someone walking down the street smoking a Behike, it could be legal. Whereas for the past decade, it couldn't have.
