Nobody knows: There are zero studies of e-cigs, and nobody knows what they will do, even with no nicotine. Nicotine is not the cause of cancer anyway - it is the complex hydrocarbons (tars) in the smoke. It is likely that e-cigs will prove safer than smoked cigarettes, the propellant in these gadgets is propylene glycol, and nobody knows what inhaling them, or the oils, flavorings and additives will do.
