We are currently enrolling healthy adults who are 18-45 years old for a research study at the Johns Hopkins Bayview Medical Center. The purpose of this study is to learn more about effects of oral and inhaled delta-8-tetrahydrocannabinol (D-8-THC) and delta-9-tetrahydrocannabinol (D-9-THC), which are both found in the cannabis plant. This is not a treatment study. 

Study participation involves the following:
- One 1-hour virtual screening evaluation
- One 2-hour in-person screening evaluation
- If you are eligible, 5 OR 10 study sessions where you consume delta-8-THC, delta-9-THC, or placebo vaporized or in an edible brownie.

Study sessions run approximately 7:15am-5:30pm on the weekdays and each session must be at least 6 days apart. You are not allowed to drive yourself home on session days. 

Up to $3,560 can be earned for completing all portions of the study procedures. If you elect to only do 5 sessions, you can earn up to $1,810.
