is it common pratice to admint to hospice once cancer is diagonised as terminal?

I am sorry to hear that you have a loved one who is under hospice care.  However, I feel that this answer is better directed for a health care provider and not an attorney.  I can tell you that usually (based on my general knowledge), once hospice is involved, it usually means the patient has been given a certain amount of time left to live, usually 6 months to a year.  In addition, hospice care is usually "comfort" care and I do believe that morphine is often given to keep the patient comfortable.   However, this should not be considered medical or legal advice and I highly recommend that you direct these questions to the hospice provider or some other health care provider who is familiar with hospice and/or your loved one's current state of health.   NOTE:  This response should not be considered legal, or medical, advice.  No attorney-client relationship exists or is formed by this response.
