There have been extensive studies on the level of CO2 toxicity.
Some people get a headache at 0.5% (5,000 ppm).  Many people get a headache at 1.0% (10,000 ppm).  People start dying at 15% (150,000 ppm).
The Apollo 13 astronauts were subjected to high CO2 levels, very close to 15% before the ground crew figured out how to reduce the CO2 content in the much warmer capsule as the LEM was under -100 F or so.
It is a fact that the Earth has experienced much higher levels of CO2 in the far distant past, up to 8,000 ppm.
If CO2 toxicity was a serious problem, then hydrocarbon (coal, fuel oil natural gas) power plant workers would be continuously sick as the stacks emit 10% to 20% CO2 depending on load of the device.
