not sure what you are getting at, but no, I do not deny, we all inhale CO2, and we exhale it as well. Our exhalations are life giving in the event of having to perform CPR, so there isn't enough CO2 there to harm anyone. Any gas can be a poison in the wrong concentrations, even O2.

I thought you were being sarcastic in your reply to MDM. If that was not the case, my apologies.
