toxic [ˈtɒksɪk]
adj
1. of, relating to, or caused by a toxin or poison; poisonous
2. (Medicine / Pathology) harmful or deadly
[from medical Latin toxicus, from Latin toxicum poison, from Greek
toxikon (pharmakon) (poison) used on arrows, from toxon arrow]

(Definition 2) CO2 is harmful or deadly to most animal life when
concentration in the breathing gas is excessive. Therefore, it is toxic.
Admittedly, not as toxic as a lot of other gases, including carbon
monoxide, but still toxic.

You are right.
However,
If there were no CO2 in our lungs, we would die.
