I can't prove it but I think my use of medical cannabis, high in CBD and low in THC, is helping with my brain inflammation, which I have long known to exist.
I haven't noticed that my memory problems are better but all other aspects of brain fog are better. I can think better and quicker, I can type with fewer errors and at a much faster rate. I still am easily distractible but not nearly as easily as before I started growing and using my own medical cannabis.
