Contribute to CHS Research

You use cannabis and don't have CHS? Your data is just as valuable.

We're comparing cannabis users with and without CHS to understand why some people develop it and others don't. By sharing your anonymous usage data, you help us identify patterns that could lead to better prevention and treatment.
