I have a friend his father has canser but he cant talk to him because of he is full of morfin is it possible to use amphetamine so they can talk?

Cant use: Morphine is used for the control of pain from malignancy. Amphetamine is a potent central nervous system (CNS) stimulant that is used in the treatment of attention deficit hyperactivity Obviously if the dosage of pain medication has produced suppression in responses a different drug should be used like dilaudid or a pain patch. Tens pad can be used. Needs pain management.
