did you read the article? No one said everyone who abuses drugs dies. It says:
While 800 overdoses have occurred on the premises, none resulted in death because of the medical supervision provided at InSite, said Thomas Kerr, a University of British Columbia researcher who has extensively studied the program. His research also has shown an increase in addicts seeking drug treatment and a decrease in abandoned syringes, needle-sharing, drug-related crime and other problems since the clinic opened, he said.
I don't understand you asking how they are saving lives if they are zombies anyway? If they overdose and are saved, that is saving lives. It seems very self-explanatory to me. Maybe i'm so whacked out on drugs I can't think clearly, but I do not understand it when you say "There's just no logical reasoning to support something like this except the fact that the person maybe in fact a fellow drug abuser." My logic is 800 lives saved = good.
If treatment options are offered, then this would be one of the few places they are exposed to options. Do you think the average drug abuser hangs out at Narcotics Anonymous meetings, rehab center parking lots and methadone clinics when they're bored?
