What to Expect

Up to 77 people from the Denver area will join this study. If you take part, you’ll start with a video call (Virtual Baseline Visit). Then, a mobile lab will come to your home for 3 or 4 in-person visits over the first 2 weeks. About 6 weeks later, you’ll have one last visit by phone or video call. You’ll choose a cannabis (marijuana) cream, lotion, or salve to use for your joint pain. You can pick one with THC, CBD, or a mix of both. You can decide how often you would like to use it. At each visit, you’ll answer questions about your pain, mood, sleep, and how the product is working. You’ll also do short tests for memory, thinking, and movement. We will take a small blood sample at each in-person visit to check for cannabis in your blood. You’ll use a phone app (or paper diary) to track when and how much of the product you use, along with any side effects or other pain meds you take. The final virtual visit will ask how long you used the product, how well it worked, and if you had any side effects.

Study Duration

The study will last about 8 weeks. You will have 4 in-person visits during the first 2 weeks. At each visit, we will check your health and ask about your joint pain. Then, about 6 weeks later, you will have one final visit online to follow up.
