Somebody very close to me has schizophrenia, depression, social anxiety, etc. And deals with all of this alone, he also has almost no financial support and works incredibly long hours to support himself and his family and hardly gets any sleep. I'm helping him look into things to help with his anxiety as he has problems with long time abuse of painkillers and its started affecting his memory. He also has sharp headaches and nosebleeds. 

Literally nobody has helped or supervised him as a child so he turned to these drugs which I'm not really in any position to tell him to stop taking as they keep him from actively attempting suicide but also drastically harm him as well.

He's asked me about my thoughts on medical cannabis and I've said I think it's fine if it's been proven to be a good alternative to other options and would actually help, but I don't agree with its recreational usage and let him know that it's incredibly dangerous to take on a regular basis as it increases the chances of him developing schizophrenia which he already has and psychosis. I'm not a doctor but if he gets into a bad trip or this harms him or leads him to suicide I live in a different country and won't have any way to help. 

Anxiety medication is also too expensive for him to afford. If anyone has any tips or things they take for anxiety that he won't get addicted to or make his schizophrenia worse please let me know. He's asked me to look into this for him as he doesn't have the time.
