We need to stop the spread of desease and programs like needle exchange are the only way to circumvent the spread of disease.
We need to protect the innocent from disease and there are only two ways to accomplish this, either make efforts to stop the spread of disease carrying persons who
will not change their behaviour, as we have
tried and
tried to no avail, or we do what Mao did.
"
Mao Tse-tung was by far the greatest therapist of drug addiction in world history.
He threatened to execute opium addicts if they didn’t give up. Threats to murder were about the only utterances of Mao’s that could be believed, and
20 million addicts duly gave up."
This is the only other real choice. We, as a society do not believe it is right to murder all drug addicts, yet it works because the threat of quick death overrides the
kick drug addicts desire.
So, unless you are willing to kill every addict on sight, then stopping the spread of disease is the only recourse!
