Could be low on oxygen. That will cause bad headaches

Haven't tried yet. I also have Chronic Migraines and thought the oils might help those. If it did i might be able to get out more.

I am starting to research CBD...oil or capsules. I don't see any mention of it helping COPD.
I thought I saw a post on here ( I am new) with good results.
Anyone have any helpful hints?

I often wonder if anyone has used it successfully, I asked the research mob and they said no studies being undertaken at this stage
