● This is not a treatment study. Although participants may experience temporary effects of the study medication, this is not to be expected to have long-term effects, as they will only receive a single dose on each test day.
● Participation will last about 6-8 hours per day for 3-4 test visits.
● During the test visits, participants will be asked to take medication containing a different dose each day. The study team can further elaborate on this.
● Participants will be asked to complete questionnaires and computer testing.
