Living in the bahamas, I have noticed that the cigarettes here are much, much smoother for me to smoke. I occasionally got a sick feeling in my stomach from some cigarettes back home, but I never get it here. In fact, the smokes are smoother... But I feel like I don't get a buzz at all here (unless I'm drinking). Even with Marlboro or Dunhill reds.
Maybe it's from the fireproofing they put in the paper back home. They aren't worried about such things here.
