CBD oil and type 2 diabetes

I was wondering if there is anyone out there who has tried CBD oil for arthritis or anything else for that matter that
might help? I am a type 2 diabetic and as you all know we can't try
everything, but I desperately need something to help me cope with
arthritis in my lower back. I started with paracetamol which isn't much
use and the doctor prescribed co-dydramol which is a bit stronger but
can be addictive so I'm scared to take too many of them! I work in a
school as a teaching assistant, I have a role for September thankfully
but worry that the arthritis will prevent me from doing my job properly.
I would appreciate any advice!!
