I am slowly retreating from this school of thought seeing how ineffective states and provinces in the US and Canada have done with decriminalizing cannabis, resulting in an arguably more thriving black market that differs than the one pre-legalization. Call me pessimistic but I think as we decriminalize other drugs their black markets will mutate in a similar way.

In addition I am curious on your opinion and that of others on if a line should be draw and what characteristics that line is to be drawn on.
