Healthy volunteers needed for cannabis/CBD research

Participants will be healthy adults age 18–55. They will first complete an in-person screening session (lasting three hours) to determine study eligibility. Participants who are eligible and agree to be in the study will orally consume a liquid that contains substances found in cannabis, including CBD and THC.

Participants will use their assigned drug once in the lab (in a session lasting about seven 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 one-hour visits on days 2, 7, and 14. They will also do a final one-hour visit one week later (on day 21).

Total possible earnings are $860.
