the early seventies doctors in the UK were allowed to prescribe heroin to users. The US 'war' on drugs put an end to this practice. Pure heroin administered properly by someone who knows its properties is a safer drug than paracetamol and harder to overdose on. Up until this time many people who had become addicted to it through medical procedures(such as ex military patients) lived a normal life on it with no outward signs of addiction or ill effects.
Once doctors were not allowed to provide it anymore there was ca huge rise in black market heroin and the crime rate shot up as people stole money to get their fix.
Also, all the physical ill effects of an addict do not come from the heroin but with what the dealers cut it with - heroin on its own is a safe drug. People over dose and die when they unwittingly get pure street heroin
and take too much or when they have not been on it for a long time and have had their tolerance reduced.

In conclusion, a program of this sort is safer for the addict and reduces the anti-social effects black market drugs have on a society - a win win situation.

Prohibition never works.
