The most exotic I ever had was from Nicaragua - brand was called Queen Elizabeth, and they were stronger than the strongest ones we have (John Player's Specials, in a black pack, for to match your lungs.) That was decades ago.

I tried a pack of those herbal cigarettes on one of my previous attempts to quit - Magic, they were called. Sure enough, after one puff, the mere thought of a smoke made me feel ill for six months (I was going for a three-month bet.) Dunno what's in those, but damn, they were horrible.

Otherwise, I haven't touched nicotine in two years (or alcohol, either), and just smoke (well, "vape", I guess, these cartridges are much nicer than mucking around the old-fashioned way) cannabis extracts now. :P Went through a medical thing, so I have to settle for that and caffeine. Husband still smokes though. No, I don't make him do it outside, because I wouldn't put up with that shit myself, and anyway, all shit like that would do is expose my own weakness. Go on, tempt me. I'm done.
