Do I have to specify that I was talking about humans?
IIUC you seem to be implying that doing drugs isn’t intrinsically rewarding for non-addicted people.
Non-addicted people generally understand that addictive drugs like heroin or cocaine can give them short-term rewards but potentially hamper the satisfaction of their long-term preferences, hence they assign a negative expected utility to them. On the other hand, eating pizza in moderate amounts is consistent with the satisfaction of long-term preferences.
