PADI OWD is an 18m depth course so its unlikely to go in to great detail but it does discuss narcosis in general terms. PADI deep deals with it more specifically and involves cognitive tests at 30m to demonstrate the effects of narcosis. C02 was discussed on my PADI deep diving course in relation to smoking and breathing resistance on regulators and skip breathing. My instructor Joup was a deep tek diver in his spare time so that may have influenced the issue.
IMHO the effects of retained C02 have been highlighted in the last ten years since the wide spread uptake of CCR in recreational diving. C02 has since been promoted to the No1 threat in my personal list of diving dangers.
