I noticed quite a big difference in subjective feelings of nitrous when I breath it maintaining quite normal oxygen level (SpO2>95) and when I am partially deprived of oxygen (SpO2<90). The feeling when deprived of oxygen feels much more intoxicating when I use the nitrous only even in high concentrations. Maybe all the psychedelic effects users write here are not caused by nitrous itself, but from a combination of nitrous and oxygen deprivation.
I have never felt unconscious from nitrous, but have achieved 65 SpO2 for several seconds when used it without hyperventilating. There is a subjective difference between the effect of nitrous and effect of nitrous + oxygen deprivation for me.
Also, maybe CO2 intoxication have its influence when we are breathing the substance and hold our breath for a long time without exhaling? Sometimes I feel absolutely no need to inhale/exhale even after about 2 minutes, and only the fear to lose consciousness forces me to breath again. In normal conditions I am not able to hold my breath for more than 1.30. CO2 is known as psychedelic in high concentrations (in mixture with oxygen, Carbogen).
What do you think about this?
