I know it's a little off-topic in terms of your original question, but be aware that the definition of "caregiver" can be pretty specific. Here in California, the legal definition recently changed, making it very difficult to qualify for "caregiver" status under California law. Lots of folks who were using the caregiver classification as a way legally carry medicine are no longer covered by this classification.
