What this trial studies

This study investigates how acute exercise influences cognitive functions and blood markers related to brain plasticity in individuals who regularly use cannabis. It aims to compare the endocannabinoid system's response to exercise between chronic cannabis users and non-users. Participants will undergo activity tests to assess these effects, focusing on the relationship between exercise and neurogenesis. The study seeks to understand the potential benefits of exercise in modifying the effects of chronic cannabis use on brain health.

Why it matters

Potential benefit: If successful, this study could provide insights into how exercise may improve cognitive function and brain health in chronic cannabis users.

How similar studies have gone: While the specific approach of this study is novel, previous research has indicated potential benefits of exercise on brain health, suggesting a promising area of investigation.
