How it works
Opioid analgesics such as morphine sulfate have been used to treat chronic cancer pain for many years. In most cases addiction
does not occur. However, over time your body becomes used to taking morphine, so if you suddenly stop taking your Morphine

It is important that you discuss this issue with your doctor.
