Hey I smoke a little pot most evenings to give myself a night off from PTSD, I personally smoke small amounts to relax myself if I've had a tough day or am stressed. There are studies which support MJ for PTSD. Personally it relaxes me but also makes my brain a little more tangential so I can get some more invasive thoughts than I'd get when I was sober but they don't upset me as much as I've had a smoke. Otherwise for something which works which is more anxiety based I'd suggest full spectrum CBD oil. I've been taking that a month and its amazing for my anxiety etc.
