Brief Summary
This is a single-group, within-subject, double-blind, double-dummy, placebo and active-controlled study evaluated whether the FDA-approved cannabinoid cannabidiol (CBD; Epidiolex) would enhance analgesia, subjective reports, and cognitive performance when compared to the FDA-approved opioid hydromorphone (Dilaudid). This is study 2 is a series of studies.

Outcome Measures
Primary Outcomes (3)
Peak Cold Pressor Tolerance
Peak amount of time participant submerged hand in cold pressor (5 degree circulating cold water) laboratory test of pain as a function of double- blinded study medications (range 0 -300).
8 hour study session
Peak Self-report Rating of "Drug Effect" (0-100), as Measured by the Visual Analog Rating Scale
Peak self-report rating of "Drug Effect" on a 0 ("none at all") to 100 ("extremely") visual analog scale as a function of double- blinded study medication, wherein higher values indicate stronger subjectively-experienced drug effects.
8 hour study session
Peak Number Accurate on Circular Lights
Peak number accuracy on the Circular Lights fine motor task as a function of double-blinded study drug administration. Participants were provided 60 seconds to press buttons that are lit in randomized order and displayed automatically on a circular lights wall mounted unit. The primary outcome is the number of lit buttons that were accurately pressed within 60 seconds, which is a metric to assess fine motor impairment. Lower numbers are indicative of greater drug-related impairment. There is no upper limit on the circular lights task.
8 hour study session

Placebo+Placebo
PLACEBO COMPARATORWithin-subject double-blind, double-dummy administration of placebo + placebo. Order of dose randomized session days 2-5.
Hydromorphone+Placebo
ACTIVE COMPARATORWithin-subject double-blind, double-dummy administration of hydromorphone (oral) 4mg + placebo. Always administered during session 1.
Hydromorphone (oral) 4mg + Cannabidiol 50mg
EXPERIMENTALWithin-subject double-blind, double-dummy administration of hydromorphone (oral) 4mg + cannabidiol (oral) 50mg. Order of dose randomized session days 2-5.
Hydromorphone (oral) 4mg + Cannabidiol 100mg
EXPERIMENTALWithin-subject double-blind, double-dummy administration of hydromorphone (oral) 4mg + cannabidiol (oral) 100mg. Order of dose randomized session days 2-5.
Hydromorphone (oral) 4mg + Cannabidiol 200mg
EXPERIMENTALWithin-subject double-blind, double-dummy administration of hydromorphone (oral) 4mg + cannabidiol (oral) 200mg. Order of dose randomized session days 2-5.
Interventions
Within-subject double-blind, double-dummy, study design wherein all participants received all doses in 8-hour outpatient sessions. Primary outcomes assessed during 8-hour outpatient sessions and included laboratory pain testing, subjective reports of drug effects, and cognitive performance, evaluated as a function of study medication condition.
