Study Background

Traumatic brain injuries can negatively affect your work life, interpersonal relationships, and independent living, and they can be difficult to treat. The chronic symptoms of a TBI can respond in many different ways to one treatment, and TBI patients often receive numerous therapies that may not work. 

There is a growing awareness of cannabidiol (CBD) as a possible treatment for TBI, but limited scientific evidence so far. That’s where our study comes in. We want to investigate how CBD affects symptoms of TBI.

Your participation in this study may help researchers improve treatment approaches for TBI. Further research today and join our compensated study
