If you have the Vice channel on your cable provider, I highly recommend checking out a show called "Weediquette", and look for the one titled "Stoned Vets". It shows the problem of PTSD, and shows what the results are of veterans who have used marijuana as a way to treat it, as well as shows another veteran who is taking pills from the VA and is scared to try it as a treatment, because it might invalidate his health care with them (he's in a non marijuana state). The vets that used marijuana? Marked difference between them and the dude who is getting his medication from the VA, not only in outlook, but physical appearance and health as well. Watch that show, and see how much cannabis has helped veterans with PTSD.
