| > That's a shame. The "smoke" from e-cigarettes is just vapour Saying "just vapor" means nothing here; consider "just chlorine vapor," for instance. Obviously the substance that has been vaporized is the important part. The most common e-cigarette vapor, propylene glycol, does have very low toxicity. But you still might not want to inhale it constantly -- no longitudinal, long-term study has been performed that simulates the e-cigarette use of PG and shows beyond doubt that it is safe. > and no more harmful to the people around the user than steam from a kettle. Nicotine is a known carcinogen, and e-cigarette vapor contains nicotine. Tea kettles do not release vaporized nicotine. The e-cigarette vapor may have a low concentration of nicotine after being exhaled, but again, nobody has extensively studied the results of breathing second-hand e-cigarette vapor over a long time period. Your assertion is completely unsupported by evidence. > I'm harming nobody but myself with it. You cannot back that up with evidence. This is your guess, and it could be wrong. Now, I happen to think that it is _likely_ that e-cigarettes will be shown to be much less dangerous than tobacco cigarettes. But my opinion, just like yours, is meaningless since it's not backed up by evidence. |
Is it? All I can find is that it promotes tumor growth if the tumor is already there but doesn't cause them by itself.

Clearstream [1] was done and at least one other study (can't remember the name atm). Nothing completely conclusive but at least it points towards it being rather safe.
