Healthy adults age 18-55 are needed to take part in a Johns Hopkins research study. The study will require 6 total visits to the lab (located at the Bayview Medical Center).
Participants will first complete an in-person screening session (lasting 3 hours) to determine study eligibility. Participants who are eligible and agree to be in the study will orally consume a liquid that contains substances that are found in cannabis including CBD and THC. Participants will use their assigned drug once in the lab (in a session lasting about 7 hours), and also at home twice per day over the 14 days that occur after the first session. During this 14-day period, participants will visit the lab again for 1-hour visits on days 2, 7, and 14. They will also do a final visit 1 week later (on day 21), which will be 1 hour.
