SUBJECTIVE INTOXICATION INDUCED BY NITROUS OXIDE IN VARIOUS CONCENTRATIONS

Scandinavian Journal of Psychology March 1, 1962 Marianne Frankenhaeuser, Gundla Jarpe

Subjective intoxication from nitrous oxide increases regularly and pronouncedly with higher doses, as measured by magnitude estimation. Both the intoxicated subjects' own estimates and observers' ratings showed this pattern. Objective performance changes followed the same general trend but were much less pronounced. The authors concluded that subjective scaling methods are well suited for measuring drug-induced changes in subjective variables.
