IMO, the most significant part of this doctor's ideas involve the use of this new therapeutic agent, "polymorpine" (not "polymorphone" as it is incorrectly spelled in the article) for the use of maintenance treatment. It is an organic biodegradable polymer which releases morphine in a controlled manner. It is given by injection, the best I could tell from reading a few abstracts of a paper that was published on it in 2012 (the full article must be purchased for some exhorbitant fee - which is a whole nother issue with me - scientific papers often will cost the reader on the order of $30 just to read the full article if you don't have a subscription to that particular journal), and releases morphine over 3 days.
Use of morphine as a maintenance drug instead of methadone would broaden the opioid maintenance therapy options available to addicts, and is more often "liked" than methadone or buprenorphine.
This has much more of a chance of being legislatively approved than the idea of heroin decriminalization.
I think what would make things much more tolerable for addicts' lives in this country and others would be if the laws were changed to allow a doctor to prescribe any opioid drug for maintenance, with a 30-day supply being the norm. So, people wouldn't have to go to clinics, could get any opioid drug they preferred (as long as it's not illegal like heroin), and wouldn't have the constant fear of involvement with law enforcement entities. Shit, just changing the law to permit a 30-day supply of methadone would be very significant.
This is a more of a realistic goal than total legalization, which would be my and many others' preference here and other places.
Availability of safe zones where illegal narcotics could be used under medical supervision would be a good thing too, but I think it presents too many problems vis-à-vis police presence just outside the spot, ready to arrest drug users going in, as they could be relatively certain that people going in would be in possession of illegal drugs.
But if all this doctor could do were to get legislation passed allowing the use of polymorphine for maintenance of addicts, I think that would be a significant and laudable victory for our cause. I'd be on board for treatment with that substance for sure.
A slightly different topic raised in the article dealt with the sociology of how drug addicts create more addicts by the manner in which illegal drug trade operates. One user, knowing a good "connect" or "hook" for narcotics will often turn his mates on to these drugs in the hopes that he can score for them, availing himself of a cut of the drugs in exchange for his services. Things like making any opioid available for maintenance would tend to disrupt that pattern of distribution, and thereby serve to mediate the spread of addiction to opiate drugs. Of course, if you knew someone who was getting something like 270 40mg oxymorphone tablets a month for maintenance, you'd probably be tempted to try to convince him to part with some of them, and he might agree to do that, so this paradigm for maintenance would present a huge opportunity for drug diversion, no doubt.
Perhaps this polymeric means of drug delivery, with a depot injection every three days (maybe they could increase the window of drug delivery to something like 30 days with pre-existing technology used in Vivitrol for a chemically similar substance, naltrexone) could be adapted to incorporate other opioid drugs so that diversion would not be an issue.
