Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Some research suggests that administration of oxytocin with oxycodone may reduce its abuse liability and improve its ability to reduce pain. In a 6-session laboratory study, the investigators will be evaluating the effects of oxycodone and oxytocin (combined and separately, across sessions) on experimentally-induced pain, subjective effects, decision-making, and activation of different neural substrates.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The overall project goals are to determine oxytocin effects on oxycodone's subject-rated abuse liability, experimental pain, and to describe the neurobehavioral mechanisms underlying interindividual differences in these effects. Generally healthy individuals (determined via medical history review and a screening session) will, after informed consent, self-administer intranasal oxytocin (or placebo, containing the same ingredients but no oxytocin) shortly after oral oxycodone or placebo in a non-residential, double-blind, randomized, placebo-controlled, within-subjects laboratory study. Prescreening will assure MRI eligibility and drug application safety and, using a validated, comprehensive pain history interview, determine previous or existing chronic pain conditions, including current pain medication use.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Individuals fluent in English will participate.
* Must report recreational use of opioids.
* Be within 20% of their ideal body weight.
* Are not currently experiencing chronic pain (pain on most days during the past 3 months)
* Have a systolic blood pressure of \<=140 and diastolic blood pressure of \<= 90, and a heart rate \<= 90 beats per minute.
* Participants must also have a normal electrocardiogram (EKG) reading and bloodwork indicating no major health contraindications.

Exclusion Criteria
