I doubt vaping has the health consequences that cigs do. Baking the plant at a precise temperature needed to just release the desired chemicals instead of burning it and releasing all toxins presumably would result in less cancer. Cigs also have filters that attempt (and fail) to trap the unwanted chemicals and iirc there’s also some recent research that the filters themselves have some negative health consequences (for both the smoker and for the environment when the discarded filter chemicals leech into the ground water).

Note I’ve not studied this in depth but that’s my off-the-cuff understanding.
