History of Changes


More scientific information is needed about medical marijuana use among HIV positive patients. There is conflicting information about the use of marijuana, use of medical marijuana, and the associations between them and health status/health risk behaviors/health care utilization. In addition, it is not clear whether patients who participate in prospective clinical studies differ from participants who do not participate; if there are differences between those two groups, then this would limit generalizability of knowledge about these issues.

The goal of this project is to describe the use of marijuana among HIV positive patients and its association with health status/health risk behaviors/health care utilization.
