Cannabis And Pain & Performance: “CAPP” Study
What is this project about?
Our study will examine the effects of medical cannabis on chronic pain by looking at how people type on a personal computer (typing pattern, not what you type).
Typing (keypress timing) is a “muscle memory-type habit” that can be affected by chronic pain and medications or even cannabis use. We want to study how people type as a new way to understand the effects of medical cannabis on chronic pain.

The study protects each participant’s privacy and confidentiality.
We only collect information on how (not what) you type.
- The CAPP Study looks at how cannabis use interacts with chronic pain. We will look at whether (and for how long) medical cannabis helps your chronic pain.
- We will look for possible effects of cannabis use on anxiety and how well you sleep.
- This project is a collaboration between the National Institutes of Health and Rutgers University.

What will I be asked to do?
- Complete a 1.5 hour baseline assessment (online or in-person)
- Install an app/software on your phone and computer to do daily surveys and collect typing “cadence” data*

*Note: The software will examine speed and typing rhythm, not what is typed
