👉 The Madrid Fluid, also known as the Madrid Protocol, is a controversial scientific study that purports to demonstrate the efficacy of a specific type of cannabis extract in treating COVID-19 symptoms. Conducted by a group of researchers affiliated with the University of Madrid, the study involved administering a high-potency cannabis extract to 60 patients with mild to moderate COVID-19 symptoms and comparing their outcomes to a placebo group. The Madrid Fluid gained attention for its rapid dissemination through social media, despite lacking rigorous peer review and facing criticism for potential methodological flaws. While some supporters argue it shows promise, the scientific community remains skeptical due to concerns over sample size, lack of control groups, and the absence of long-term studies. As such, the Madrid Fluid remains a topic of debate rather than a widely accepted treatment for COVID-19.
