  Purpose

The purpose of this study is to conduct experiments to examine subjective and reinforcing effects of nitrous oxide. Mood altering and psychomotor effects will be tested on non-drug abusers and preference procedures will be used to assess reinforcing effects. Comparisons between nitrous oxide, opiates, and benzodiazepine antagonists will be made. To examine effects of subanesthetic concentrations of nitrous oxide on cold-pressor pain in humans.
