If an addict were able to access drugs via the NHS or something similar, then they would not have to go out and buy illegal drugs.
Not all crime gangs raise income through selling drugs, but most of them do in my experience. So offering an alternative route of supply to users cuts their income stream off.
I think addiction to anything – drugs, alcohol, gambling, etc – is not a good thing, but outright prohibition hands revenue streams to villains.
Since 1971 [the Misuse of Drugs Act] prohibition has put billions into the hands of villains who sell adulterated drugs on the streets.
