&gt; Heck even if you breath water vapor all day it won&#x27;t be good for you, there is no way in hell that breathing in &quot;hot&quot; vapor can be good<p>Is the vapor really any warmer than body temp when it goes into your lungs though ?  I just conducted an experiment where I took a puff of a vaporizer but kept the vapour in my mouth, then I probed with my index finger and honestly the air temp felt about the same as it does without the vapour.<p>Also I wonder if vaping a pack a day while living in the a prestine wilderness setting would be more safe than breathing regular air all day in a large metro with auto air pollution.  I suppose it probably depends what flavors are in your liquid, and which city.<p>Then there&#x27;s the question of whether or not it&#x27;s safe to be nicoteen in the first place.  The way I look at it sugar and coffee are probably equally bad if not worse for the body, but I haven&#x27;t looked at it in depth
