National registry tracking medicinal cannabis use and health over time
Development of a Longitudinal Observational Research Registry for the Study of Medicinal Cannabis Use and Health
['FUNDING_OTHER'] · JOHNS HOPKINS UNIVERSITY · NIH-11336931
This project will follow people who start using medicinal cannabis to track what products they use and how their health and daily functioning change over time.

What this research studies
You would be invited to join a nationwide registry if you are newly starting medicinal cannabis. Participants complete web-based surveys before starting and at repeated intervals afterward to report symptoms, product use, and daily functioning. A subset of participants will do intensive real-time reporting (ecological momentary assessment) and may provide biospecimens for lab tests to check for things like liver effects. The program also tests products linked to reported adverse events to help identify unsafe or contaminated items.
Who could benefit from this research
Good fit: Ideal candidates are adults in the United States who are newly initiating medicinal cannabis or hemp-derived CBD for symptom relief and who can complete online follow-up.
Not a fit: People who are not using medicinal cannabis or who have been stable long-term users unwilling to provide follow-up data are unlikely to directly benefit from participation.
Why it matters
Potential benefit: If successful, this registry could help patients and clinicians choose safer, more effective cannabis products and detect unexpected harms earlier.
How similar studies have performed: Previous small or short-term studies have produced mixed findings, and large national longitudinal registries like this are relatively new.
