Hi Blue7,
I get what you're saying as I didn't want to get high from mm either. I really just needed it to be able to sleep. That part was very tricky but I did find something that worked for me but since that wasn't your question I won't include it here. PM me if you want more info.

As far as pain and almost instant relief, vaping is the preferred method. It doesn't last as long, but then again if you don't like the feeling it is gone faster than other methods. Tinctures are often ethanol base, being straight alcohol and that irritated my neuropathy. There's also some with a glycerine base. Anything you ingest will take longer to feel and will stay in your system longer.

I would suggest doing some research before your appointment on Tuesday. There are so many different strains for different results. And of course everyone is different so what works for one person may not for you. I bought the book "Cannabis Pharmacy: The Practical Guide to Medical Marijuana" by Michael Backes which has tons of useful information on the subject.
