Technically it's "morphine is bascially just heroine" as morphine is asynthetic drug based on the chemical structure of Heroine. It's quite a complex structre as well with a briding chain stretching across the molecule.

Synthetic cocaine substitutes are prescribed for pain relief (codeine, cocodamol, codydramol).
