What this trial studies

This observational study aims to track the use of commercially available hemp and cannabis products marketed for immune support among individuals experiencing acute infections like influenza and COVID-19. Participants will be monitored for their consumption of these products and the associated effects on their symptoms. The study seeks to understand the safety and efficacy of cannabis in real-world settings, particularly given the rapid acceptance of these products in the market. By utilizing a prospective observational design, the research aims to provide insights comparable to randomized controlled trials, despite the inherent limitations of observational studies.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older who are active participants in the Pennsylvania medical marijuana program and currently experiencing symptoms of an acute illness.

Not a fit: Patients who are pregnant, breastfeeding, or planning to become pregnant will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide valuable insights into the safety and efficacy of cannabis products for immune support during acute infections.

How similar studies have performed: While observational studies on cannabis use are becoming more common, this specific approach to studying commercially available products for immune support is relatively novel.
