I posted this before. Hope this drug comes out soon.

Magic Mushrooms Expand the Mind By Dampening Brain Activity:

new brain-scan study helps explain how psilocybin (active ingredient in magic mushroom) works — and why it holds promise as a treatment for depression, addiction and post-traumatic stress.


What caught my attention is :

In order to keep us focused on survival, Huxley claimed, the brain must act as a “reducing valve” on the flood of potentially overwhelming sights, sounds and sensations. What remains, Huxley wrote, is a “measly trickle of the kind of consciousness” necessary to “help us to stay alive.” If this drug comes out I believe it can help PCS folks in many ways.

With Meditation you can achieve that state but with concussed/injured brain it can be very difficult

Cheers!
