Since smoking a clove is equated to smoking a chemical free cigar, probably not the best way to go. That's a lot of pressure to put on your lungs. If you are interested in using a non-chemical cig substitute try herbal cigarettes instead. No chemicals and all natural non-addictive (supposedly) ingredients. You can buy them at your local vitamin/herb store or I think smoke shops sell them. (I recently saw them at a mini-mart by my house, but I live in southern California where that kind of thing may be more prevalent.)

Just so I don't get flamed ( :)), I've never smoked these and am not suggesting it's a good idea...just giving feedback.
