Well, "reducing the money made through illegal drug sale" can be applied to all drugs, right?
It reduces the crime rate and increases the addicts number.
But you are right when you say that the addicted ones are already lost for society, i think this can give the wrong signal on ending or decreasing the consume of heroin.

Only God Can Judge Me
الله فقط يمكنه محاكمتي

I am you and you are me, if you love i love, if you suffer i suffer
أنا أنت, و أنت أنا, إذا أحببت نفسك أحببت نفسي, إذا عانيتَ عانيتُ
