Résumé : |
FRANÇAIS : L'expérience d'inhalation de différentes concentrations de protoxyde d'azote, menée ici sur des volontaires sains, montre peu d'effets de renforcement, contrairement à d'autres études préalables. ENGLISH : The subjective, psychomotor and reinforcing effects of nitrous oxide at subanesthetic doses (30% and 40% in oxygen) were determined in normal healthy volunteers using a choice paradigm. Thirty percent nitrous oxide was chosen no more often than oxygen (41,6% choice rate), indicating that, for most of the subjects tested, extended inhalation of this nitrous oxide concentration was no more reinforcing than oxigen inhalation. Forty percent nitrous oxide was chosen significantly less often than oxygen (22% choice rate), indicating that, for most of the subjects tested, extended inhalation of this nitrous oxide concentration was less reinforcing than oxygen. Nitrous oxide produced robust subjective effects (e.g., increased ratings of 'high', 'tingling'). The lack of reinforcing effects noted in the present study, given nitrous oxide's known abuse potential is discussed. (Extract from author's abstract) |
