Hi I are the new e smokes are safe there just fruit tastes no nicotine! Safer then real one no?!

? What is the purpose of smoking if not to deliver a drug? And smoke is toxic to the lungs no matter what the source.
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, but again, nobody really knows. The propellant in these gadgets is propylene glycol, and nobody knows what inhaling them, or the oils, will do.
