Summary

This research is being done to evaluate the impact of various drugs and combinations of drugs on mood, pain, and performance.

Detailed description

This research is being done to evaluate the impact of various drugs and combinations of drugs on mood, pain, and performance. Participants will complete 1 screening visit and 7 study test sessions. During the study sessions the participant will receive a study drug that may contain blinded drugs or drug combinations. Participants will answer questions about how the participant feels, perform tasks that measure the participant's cognitive ability and experience of pain, and have heart rate and blood pressure measured. While not at the laboratory, participants will be asked to wear a wristwatch that measures sleep and activity and complete questions about sleep.

Interventions

Type	Name	Description
DRUG	Blinded Study Medication - Condition 1	Participants will receive a double-blinded oral study medication as part of the participant's experimental sessions and will provide feedback regarding the effects of the medication on various measures. Though the study medications are FDA approved, the medications are being used here for a non-FDA approved purpose (though the FDA has provided permission to use these drugs in this study). Participants may receive a study drug that contains a prescription stimulant, a prescription cannabinoid (related to the active ingredient in cannabis or marijuana), a benzodiazepine (e.g., anti- anxiety medication), an opioid (e.g., a pain medication), a sleep medication, and/or an over-the-counter medication. The study is deeply blinded so that participants are not aware of possible drug conditions in the study and indication of the study drug names in the clinicaltrials.gov record would comprise the blind of the study. Detailed drug condition information will be added upon completion of study.
DRUG	Blinded Study Medication - Condition 2	Participants will receive a double-blinded oral study medication as part of the participant's experimental sessions and will provide feedback regarding the effects of the medication on various measures.
