Firstly let me say that i'm against smoking and have been trying to quit for years, i now use a filter to block some of the tar.
But, cigars and pipe smoke aren't meant to be inhaled and as far as I see it cigarettes are the only form of tobacco meant for the lungs.
Some people only mouth inhale cigarettes.
If there was anything as convenient as a cigarette, but less harmful i would prefer it, or at least an honest tobacco company could bring out a healthier option without the extra poisons. I'v seen healthier options for roll up tobacco, and even empty cigarette tubes to make your own.
