The Problem With The War On Drugs

[Vuk]

One key element of legalization is that you both effectively eliminate the criminal component (since you make it unprofitable for them). If anyone who wanted could grow a Cannibis plant in their backyard, do you think drug dealers could make anything selling it?

If anyone could grow a cornstalk in their backyard, do you think that rich, land-owning farmers could make anything selling it?
There is the matter of land needed (try growing it in a back alley), time needed, etc.
