Mood altering and psychomotor effects will be tested on non-drug abusers and preference procedures will be used to assess reinforcing effects.

To examine the effects of different behavioral contingencies in modulating the reinforcing effects of nitrous oxide in healthy volunteers."}, "eligibilityModule"=>{"sex"=>"ALL", "stdAges"=>["ADULT", "OLDER_ADULT"], "minimumAge"=>"21 years", "healthyVolunteers"=>true, "eligibilityCriteria"=>"Please contact site for information."}, "identificationModule"=>{"nctId"=>"NCT00000260", "briefTitle"=>"Effects of Behavioral Contingencies on Effects of Nitrous Oxide - 12", "organization"=>{"class"=>"OTHER", "fullName"=>"University of Chicago"}, "officialTitle"=>"Effects of Behavioral Contingencies on Effects of Nitrous Oxide", "orgStudyIdInfo"=>{"id"=>"NIDA-08391-12"}, "secondaryIdInfos"=>[{"id"=>"R01DA008391", "link"=>"https://reporter.nih.gov/quickSearch/R01DA008391", "type"=>"NIH"}, {"id"=>"R01-08391-12"}]}, "armsInterventionsModule"=>{"interventions"=>[{"name"=>"Nitrous oxide", "type"=>"DRUG"}]}, "contactsLocationsModule"=>{"locations"=>[{"zip"=>"60637", "city"=>"Chicago", "state"=>"Illinois", "country"=>"United States", "facility"=>"University of Chicago, Anesthesia & Critical Care", "geoPoint"=>{"lat"=>41.85003, "lon"=>-87.65005}}], "overallOfficials"=>[{"name"=>"James Zacny, Ph.D.", "role"=>"PRINCIPAL_INVESTIGATOR", "affiliation"=>"University of Chicago"}]}, "sponsorCollaboratorsModule"=>{"leadSponsor"=>{"name"=>"University of Chicago", "class"=>"OTHER"}, "collaborators"=>[{"name"=>"National Institute on Drug Abuse (NIDA)", "class"=>"NIH"}], "responsibleParty"=>{"type"=>"SPONSOR"}}}}
