FIRST OFF a quote from earlier
"Cuban cigars are illigal in america i think.. but thats just what i think and heard"

Really it is more illegal to bring them in and illegal to sell them in the US.
You can't tell a cuban cigar from a any other Cohiba, Monticristo or Punch cigar. A cop isn't going to care if you have cubans. UNLESS you are trying to sell them.

I really don't see why she has to use Cuban cigars. But...
You can order them online. Some sites ship to the US some dont and you have the risk of losing the shipment if it is checked.

All the cubans I have gotten over the years have come from a friend of mine that has a Cigar shop. Cigar guys stick together and have kinda a underground network of cuban cigars smuggling. I would suggest she become a regular at a shop that is Owner Operated and She will probably find a steady connection of Real Cubans. Remember Fake Cubans are VERY prolific in the US. Good Luck
