Healthy volunteers needed

Study volunteers will attend six outpatient visits designed to examine the behavioral, mood, and cognitive effects of substances found in the cannabis (marijuana) plant. There is also a separate approximately 3-hour screening visit to determine study eligibility. Visits last about 9 hours each, will take place about once per week, and must be completed on weekdays (Monday–Friday).
