My friend's mother, who lives in California, is dying of cancer, and has been 
told that she can only be given morphine for her pain if she is in a hospital 
or a hospice.  She prefers to be at home, but has been given to understand 
that she cannot get a prescription for morphine under those conditions.  

Several years ago when my grandfather was dying from cancer in Arizona, he was 
given morphine to ingest orally at his own discretion at home.  Is my friend's 
mother forbidden by law to receive morphine at home, or is it something that 
her doctor has decided (mistakenly)is in her own best interests?

Thanks for any help you may be able to give us.
