I guess you could, but it would be utterly pointless and do more harm than moral. The act of smoking itself cause all the respiratory illnesses, not tobacco per se. I've see people smoke both tea and oak, and it give them nothing but caughing and a headache.

you could smoke pot- i dont, but i dont reason it hurts. its illegal, but it shouldnt be. also, if ur trying to avoid smoking tobacco to avoid addiction, dont bother- u can seize addicted to anything u smoke- or anything period.
Many smoke shops put on the market herbal tobacco. There are clove cigarettes. You can also smoke coltsfoot and sage, amongst many other herb. At one point, American Spirit sold herbal cigarettes, but I'm not sure they still do.
