Lol Gareth!!
Killing thems a bit too far. Forced detox maybe reasonable. They always say you cant make someone give up unless they want to but surely if your that deep in the grip of heroin addiction then by definition you never will give up.
Surely forced detox then long term therapy to get to the root of the problem leading them to drugs has to be cheaper than the effects of a life of crime fed by heroin addiction???
