This is false. Arrest drug dealers day after day for a generation, and the demand will lower because new generations won't even know what drugs are, or when the effect of heroin is, therefore they won't chase it.

Demand for a good (or drug in this case) it is not inevitable. It can be disrupted too, it's not a given.

But the demand for any good cannot be disrupted without first and foremost removing the supply. So we must start disrupting the supply, which shows up every day at 6am on our street corners.
