Cannabis therapy : have you tried it? how do you access it? how effective is the treatment for you?

I have been taking CBD oil for a while now in the infused to coconut oil bottle. I couldn't take the antidepressant pills as they made all my nodes swell up but the oil doesn't. It mustn't have THC as I have never felt high at all with it. I get it from a friend. It gets rid of those awful internal shakes you get from PTSD and anxiety. Depression does still occur but it doesn't last for more than a day at a time and then its gone for a while then. It does help with inflammation a little and pain reasonably well and at least I am not doing my body more harm with prescribed opiates.
