No Smoke, No Smell, but not, No Smoke, No Harm

   I've a question today. If e-cigarettes serve up nicotine to the vaper who vapes them, is the nicotine   present in the vapor released into the air?
   Because, if it is, I don't want to be breathing it, second hand. Many vapers, supposing since smoke isn't released into the air, believe they do no harm to others by smoking in public. Nothing but water vapor, they say.
   But, apparently, that is not so. It is now being shown that the water vaper does carry toxins into the air. We can't smell them, but that doesn't mean they are not there. No smoke, no smell, maybe, but not, No smoke, no harm.
