No, CO2 will kill you at sufficient concentrations. Spacecraft and submarines need CO2 scrubbers to keep their crews alive. Apollo 13 specifically had plenty of oxygen to return to Earth but CO2 concentration would have killed the crew if they hadn't adapted a CM CO2 scrubber to work in the LEM (or the other way around, I don't remember). The atmosphere could never get to that concentration but it does exist.
Elevated CO2 levels literally slow your brain functioning down. Heavily elevated CO2 levels flat out kill you.
If you're going to come up with quips, come up with one that doesn't make the rest of us sound like blithering idiots.
you're thinking of CO
