I started smoking a pipe by smoking whole leaf cigar leaf in a pipe. It is different than in a cigar, but it is similar. I enjoyed it and still do enjoy it occasionally. You can buy whole leaf tobacco online and a lot of it has Havana seed pedigree. If you smoked cigars much you might realize that a Havana seed pedigree is not all that. There are a lot of good cigars which do not come out of Cuba. There are quality Nicaraguan, Honduran, Jamaican, etc. cigars. Many of these are grown from seed originally brought from Cuba when Castro took over anyway, but the tobacco has adapted to local conditions as plants will do. Anyway, Cuban cigars are quite good, and they are distinctive, but other cigars are just as good sometimes.
Most importantly for your situation. When you get whole leaf online it will probably come from the cigar growing country. It will be aged there, maybe fermented in piles there and it tastes like a cigar from that country mostly. The same seed grown in America will likely not get the same *processing*. I have also bought Havana from a grower in Kentucky (and gown it myself). He ages his tobacco for a couple/five years before sale. It has a very different flavor, similar, and good, but very different. I would imagine that kilning would also produce a different flavor than processing in Central America.
So, ask your friend if he ages or kilns or what. If he ferments in piles it might be like Cuban.
However, if not, it might still be very good.
