I'm in Cali. What I was told is the 'doctors' who give you your license can't recommend particular dispensaries or certain types or brands of MM.
I would have her go to a dispensary that is medicinal-based (instead of recreation-based, which is many of them). One in my area (San Francisco) is very health/medicine based, and even has classes for people new to medical marijuana, about how to manage your pain and recommends what to buy, etc. Going there is a much different experience than the more recreation-focused places.
I've found the CBD edibles (I get the chocolate bars and eat a small amount of chocolate when I'm in pain) help with my pain without causing any of the 'high' feelings.
