For me, personal health-wise (at least cardio), quitting cigarettes and switching to pipes and cigars made a night and day difference for me. I am perfectly content to only retrohale pipes and cigars (and not every puff at that) and enjoy the nicotine buzz but never crave it like with cigarettes. For example I'm not going crazy wishing I could have a cigarette on a long overseas flight. I'd _like_ to have a pipe, but I don't feel any _need_ to so. As to the cardio, after switching off cigarettes I went from getting winded walking up to the top of a parking garage to running half marathons regularly. Again, not inhaling into my lungs was certainly the big difference. I suppose I could smoke cigarettes without inhaling, but that sounds ridiculous, and certainly wouldn't be enjoyable to me.
