In Singapore there are no more than one or two drug-related deaths a year.  These deaths are not due to overdosing.  They are due to hanging.  In Singapore drug traffickers are executed by hanging.  Compare this to British Columbia where more than 1000 people are dying every year from drug overdoses.  If you want to save lives follow Singapore's example.  Enforce the law against drug trafficking with capital punishment.  Helping addicts inject themselves with drugs just isn't working.
