To answer your first question, second part first, there is absolutely no way you can tell the difference between a fake and real Cuban cigar because of your limited experience with them. Bands, seals, chevrons, EVERYTHING else can be faked with exact precisions so the even a long time Habano smoker would be fooled. The only way an “expert” can be sure to tell the difference is in the flavor. Once you get a few years of Cuban cigar smoking under your belt, you’ll know too.

In light of that the ONLY place anyone should be buying Cuban cigars is at an LCDH. There are two in Thailand, one in Bangkok and one in Pattaya City. You can buy with much more assurance there than anywhere else in Asia. There is also one in Tokyo.

For milder cigars I would recommend the Quai D’orsay Corona. A fantastic cigar with lots of flavor. You could also get an El Rey Del Mundo Choix Supreme or anything from the Fonseca line.

There are no drugs in Cuban cigars. But, as Tim said, it is illegal for an American to purchase a Cuban cigar under any conditions.
