  Purpose

This study will investigate the effects of acute morphine administration on taste acuity and how much a person eats. It is hypothesized that there will be a dose dependent decrease in taste acuity and dose dependent increase in food intake associated with acute morphine administration. Knowledge from this study will impact the future of feeding behavior and obesity research in the general population. Results will also promote exploration of the long-term effect of opioid abuse on taste acuity and feeding behavior in substance abusing populations.

Primary Outcome Measures:
  • Taste [ Time Frame: 3 hours after dose administration ] [ Designated as safety issue: No ]
    The primary outcome variable will be the taste acuity profile, which includes the taste detection threshold, recognition threshold, magnitude estimation, and hedonic response.


Secondary Outcome Measures:
  • Calories [ Time Frame: 6 hours after dose administration ] [ Designated as safety issue: No ]
    The secondary outcome measure will be the amount of calories consumed over a 2 hours period following the drug administration.
