Be clear about what's known: laboratory neuroprotection findings never translated into human evidence that cannabis helps the injury itself heal. The symptom cluster is the realistic target — chronic headaches, sleep disruption, anxiety and irritability, and pain — each with its own evidence base covered elsewhere on this site.
TBI adds specific cautions: cognitive effects of THC stack on injury-related deficits (memory, processing speed), so low doses with someone tracking your function honestly; seizure-threshold considerations apply post-TBI; and the overlap with PTSD in veteran populations means reading both pages. Neurology or physiatry coordination keeps the whole picture coherent.
