There is an argument to be made, albeit an absurd one, that the introduction of copper seeking junkies into this Euro country would help recycling and improve the carbon footprint.
It's that recycling has a smaller carbon footprint than making new copper from scratch. I think this claim is true for copper, recycling v. manufacturing.
At the very least this would increase cash flow in your economy. The cash flow coming from junkies and their newly acquired "free" copper are better off and more likely to spend some of their money on goods other than dope.
Not a serious argument, but an argument.
