Eddie,.......the problem I can see about making heroin available free on prescription is the great danger of it spreading out into the non-addict population.
In the example that I gave, of the lady in the village, who has just had her daily fix, there is no danger of the dosage being misused, which presumably is why it has to be taken under supervision, and isn't allowed to be carried home. The burden on the NHS, to take over the activities of the drugs industry doesn't even bear thinking about
Secondly, I have my doubts about how other drugs would be made legal. Take cannabis for instance. I am told that the most popular way of using this drug is to put it into a cigarette, along with tobacco and smoke it.
So we could see a situation where existing tobacco companies would be in a position to sell cannabis cigarettes, rather in the way that they sell ordinary cigarettes at present.
Considering the essentially duplicitous nature of the tobacco industry, I wouldn't trust that industry one inch.
