If you can also keep the usual tobacco-processing chemicals and other additives out, is the bare leaf, nicotine-free, arguably no worse than other common vices ?
Generally I would say that burning(flame/smoldering) anything is bad for you. Even simplest hydrocarbons (methane, propane, butane) with imperfect combustion have negative effects. You can make it slightly better, but smoke is most likely always carcinogenic.
