I'll try my best to answer, I haven't seen a lot of information on this subject. From what I know you'll need your recommendation from a cannabis friendly doctor either way. I saw an advertisement for a doctor in the Bay area who charged $50 to be a caregiver for a patient.
Your friend could go in with you on the same day of appointment and let them know you want him to be your caregiver seeing how you can be immobile at times. You'll both have different documentation, he can go buy it for you when needed, and you can go as well with your valid recommendation. There should be delivery services in the L.A county area if needed, there's someone here in Sac that provides to patients, who can't always make it to the store. My girlfriend has a doctors appointment tomorrow, I'll see if he says anything about care givers!! Hope that helped at least!!!:jointsmile:
