Who could benefit from this research

Could help

Ideal candidates for this research are individuals who are newly initiating the use of cannabis for therapeutic purposes and are registered with state-regulated medical cannabis programs.

Less likely to help

Patients who are not interested in using medicinal cannabis or who are already experienced users may not benefit from this research.

What this research studies

This research aims to establish a comprehensive registry for patients using medicinal cannabis, focusing on their demographics, the types of cannabis products they use, and the health outcomes associated with their use. Patients will be recruited nationally and will participate in web-based surveys to provide data before and after they start using cannabis for therapeutic purposes. Additionally, some participants will undergo more detailed assessments, including daily tracking of their symptoms and potential side effects, to better understand the impact of cannabis on their health.

Why it matters

Potential benefit: If successful, this research could provide valuable insights into the health effects of medicinal cannabis, helping to inform safer and more effective treatment options for patients.

How similar studies have gone: While there has been some research on cannabis use, this approach of creating a longitudinal registry specifically for medicinal cannabis users is relatively novel and untested.
