Conditions
Brief summary
Research is being conducted to better understand the physiologic effects (relating to the action of a drug when taken by a healthy person) of opioid use on oculomotor (relating to the motion of the eye) dynamics and to identify the presence of characteristics consistent with a specific drug or class of drugs.
Interventions
Non-invasive video-based eye tracking system
5 mg tablet
Oxycodone-matched placebo tablet
Subject will have to look for numbers on a screen and add these numbers together. OCAT will be presented on a computer screen with attached eye tracking device at the bottom part.

| Oxycodone, Then Placebo Participants first receive initial dose of oxycodone 5 mg tablet followed by a 30-minute rest period to allow for onset of medication effect. This rest period will be followed by a standardized set of oculomotor testing for 40 minutes. After the initial testing, a second dose of oxycodone 5 mg tablet will be administered followed by a 30-minute rest period to allow for the onset of the second dose. The second rest period will be followed by a second round of standardized oculomotor testing for 40 minutes. Participants will then return approximately 4 to 6 days to repeat the standardized oculomotor testing with placebo.
