I don’t think the research is there yet. But I bought a $45 bottle of 100 mg and I put a tiny drop in my vape every morning with my nicotine fluid and it does the trick for my anxiety. Then again I’m not psychotic anymore so you’d probably need much more to treat florid psychosis. Im just helping my anxiety a little. The bottle has lasted me a lot longer than I thought. I probably will buy another when I run out…it is helpful I say. Still expensive but considering it’s been 2-3 weeks and I still have a lot left it’s not too bad.
