While understanding that this is your opinion, I find your
statements very simplistic.

You mention your experience in dealing with these people and you
say, "They look young, fit and able to do work," and, "I have had to enter more homeless
shelters and crack dens that I care to remember."  You don't say in what role.

But
you left out that the report; "defined people with severe addictions
and/or mental illness as those with forms of substance abuse, eating and
anxiety disorders, as well as mood and psychotic disorders. It focused on
adults aged 19 to 80.

The
study estimated that 50 to 70 per cent of homeless people are dually diagnosed,
in that they suffer from both a mental illness and a drug addiction."

Substance
abuse these days includes alcoholism, a far greater problem than chemical abuse
such as heroin, crack, etc.

Are
you blaming addicts for the first experiment; or for making that first mistake
and being caught up in the tragic cycle of addiction?
