Brief Summary
In this study, the investigators will examine the effects of buprenorphine, as compared to placebo, upon physiological, subjective, and hormonal responses to a stressful speech task and a non-stressful control task in healthy adults. There is strong evidence in support of the role of endogenous opioids and opiates in mediating social behavior in humans and other animals, and particularly, in social distress. Recently it has been shown that buprenorphine, a partial mu-opioid agonist, reduces sensitivity to recognition of fearful facial expressions in humans. Here, the investigators propose to further explore the role of the opioid system in mediating stress responses in humans through the use of buprenorphine. The investigators hypothesize that buprenorphine with reduce both physiological and subjective measures of stress.

Outcome Measures
Primary Outcomes (1)
Subjective Effects as Assessed by Score on "Feel Drug", "Feel High", "Like Drug", and "Want More" Subscales of the Drug Effects Questionnaire Subjective Responses to Stress With and Without Buprenorphine
The Drug Effects Questionnaire (DEQ) is a visual analog scale questionnaire that assesses the extent to which subjects experience four subjective states: "Feel Drug", "Feel High", and "Want More". The "Feel Drug", "Feel High", "Like Drug", and "Want More" subscales are reported. All subscales are scored on a visual analogue scale (scroll bar on computer screen) ranging from 0 -100. 100 represents the highest score for that subjective state, and the higher the score, the worse the outcome.
