Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Subjective Effects [ Time Frame: 6 weeks ]
    Participants will rate "drug liking", "good drug effects", and "high" on a visual analogue scale (VAS; 1-100mm).

  2. Cold Pressor Test [ Time Frame: 6 weeks ]
    Participants will immerse their hand in a bucket of ice water to determine pain threshold and pain tolerance latencies (in seconds).
