I suppose if the government gave drugs to addicts it might solve the problem, but what's stopping me a non drug addict claiming my free drugs allowance and selling them to The addicts ?
Giving free drugs to addicts is not going to cure them.
Saying that, the horrific image at the start is not a good sign of what society is creating but it might not be drugs related, it might be some person addicted to violent video games, maybe we should give free games away to ease their addiction ?
But while we are thinking of how to solve the problem of controlling our drug crazed society it would only come at the expense of the decent hard working, mostly non drug addicted.
