That would be because Dr Marks can't see himself. The difference between a high functioning, long term heroin addict and everyone else is that the heroin addicts require large support staffs that keep them high functioning.
Not really. They require their regular fixes, but are then able to be quite functional, if highly addicted.
Where the requirement for significant resources come in is initially, vetting an addict for eligeability to enter the program.
After that it's only a question of controling the distribution. Pharmacies can function quite well as gate keepers in the process.
These do not constitute such a large portion of the population that you can say that folks who do not require them are rare. If anything it's the opposite.
The point I make is that heroin addicts require everything that everyone else requires, plus medical support staff that provide them with cheap and safe sources to feed their addiction. Equating this with the tools of the trade of medical professionals is absurd.
Pharmacies serve quite well and rather cost efficient for this purpose. It's not really that far away of their core business of dispensing prescrition drugs. The substance is different, but the logistics are exactly the same.
You may think that pharmacy robberies are a concern, but it's not really an issue. I accept that this may not universally be the case.
These systems are already in place. Maybe I'm being presumptuous but they have pharmacies where you come from, right?
If they didn't need to rob for their habit then the large 'support staff' of police is reduced.
You seem to have ignored the facts in the article. That, or there's more about your position that is not obvious, perhaps you know or have worked with some addicts and have additional experience I haven't?
