i dont understand this "medical grade heroin administered correctly is less harmful than alcohol" argument. you mean less harmful than alcohol abuse? alcohol conumed correctly, say a glass or two of red wine with dinner, must be better for you than shooting up any sort of heroin....
It works pretty much however you scale it. If you want to go with full blown addiction, compare a raging alcoholic who drinks from waking till sleep and gets the shakes within a few hours of stopping, to a heroin addict who visits a clinic 2 - 4 times a day to smoke or inject heroin (which is probably representative of the "ideal state" for a heroin addict, as demonstrated in Switzerland, Denmark, etc).
The alcoholic is trashing basically every major system in his body - brain damage, cardiovascular damage and liver damage being the most prominent. as well as the carcinogenic effect. Eventually one of those is going to catch up with them, if they're drinking at the rate described, probably within a decade or two at the longest. Detoxing from alcohol is not only extremely painful, but can cause potentially fatal seizures. All of these are caused directly by alcohol consumption, not by secondary factors.
By comparison, the heroin addict can get high as a kite all day, every day, and on top of developing a dependence, the only real long term side effects will be impaired hormone production (mainly testosterone), constipation, and digestive problems secondary to constipation. No brain damage and no major organ damage, and the problems it does cause will revert if the user reduces and eventually eliminates their heroin consumption.
Withdrawal from heroin is painful, but much more manageable than alcohol withdrawal, and almost never fatal (there are probably occasional cases where someone is already extremely unwell, and the stress of the withdrawal throws them over the edge). Again, not saying this would be an awesome life to live, you'd be forced to revolve your existence around visits to a clinic, but there's just no comparison when it comes to the damage caused to the body by alcohol on the body v. that caused by pure heroin.
The majority of the dangers associated with heroin in the media and popular culture (infection, collapsed veins, blood borne viruses, overdose), are largely or entirely the product of heroin being a black market drug and existing on the fringes of society as a result.
Infection can be almost entirely mitigated - firstly, because injection is only a necessity when the addict has to be as efficient as possible with their supply. Very few heroin addicts start out injecting - it's something which most escalate to reluctantly as a result of their tolerance to the drug building. If their supply is affordable, then they can easily consume the drug through smoking, snorting, or through replacing it with other opiates which can be taken orally (heroin when taken orally breaks down into morphine, which itself has a low oral bioavailability).
Even if the addict chooses to inject, the availability of clean injection equipment (ideally at a clinic, but it can be replicated fairly safely at home as long as you're careful), the use of pharmaceutical grade product which hasn't been handled by dealers and repackaged constantly, and the use of alcohol swabs and micron filters (which remove bacteria, as well as any other undissolved contaminants, from the solution prior to injection) reduces the risk of infection by orders of magnitude. Infections happen almost exclusively when addicts are forced to use dirty equipment to shoot up improperly filtered heroin in unhygienic locations.
All of the above applies to blood borne viruses. These are more or less nonexistent among the majority of IV drug users in countries where needle exchange programs were implemented early (with a fairly small exception among the gay community - where there's a crossover between IV meth users and men who have unprotected sex - and among long term prisoners, who share needles which have been smuggled in).
Overdose is the trickiest one - you can avoid it almost entirely if addicts are getting high in clinics (theoretically, they could get high, leave the clinic, consume some other drug on top of heroin and overdose as a result, but I've never heard of this happening). Fatal overdoses in clinics just don't happen - opiate overdoses are extremely treatable if medical staff are on hand to reverse the effects with naloxone.
If people are using outside of clinics (which isn't something I'm advocating, but for the sake of argument...), then it's trickier. But just having access to cheap, pure heroin makes a huge difference, although I know it seems counterintuitive. If it's cheap, people can smoke it instead of injecting it, which is far less likely to cause a fatal overdose (the smoker almost always falls unconscious before being able to smoke enough heroin to kill them, unless they have other downers in their system). If it's pure, people can measure their dose precisely, instead of getting varying potency from one dose to the next, allowing them to carefully track their intake and tolerance.
That leaves the other two major causes of overdose. Using with other downers can primarily be addressed through education and constant contact with health services - which of course is going to happen if the addict is getting their heroin from those services. Using after a period of abstinence can also be helped in a big way through education and through access to health services - all it would take is a reminder from the clinic that the user hasn't dosed themselves in a while and should slowly escalate their dose to make a big difference, and of course the reduction in IV use and the ability to be certain of exactly how much is being consumed would help enormously. A lot of difference could be made through a change in culture, through bringing addicts into contact with medical professionals who can teach them to be safe and monitor their use.
Anyway, I rambled on a bit, but none of this is radical. These systems have already been implemented and had massive success in certain parts of Europe.
If you want a comparison to "a glass or two of red wine with dinner," probably the best would be someone who occasionally takes a moderate dose of pharmaceutical opiates, either to relax or to treat pain, and these people absolutely exist. Not everyone who uses opiates is an addict, even if you exclude those who use them only under direct medical instruction - it's just the addicts who are visible, and the more desperate they are, the more visible. Especially with heroin, since it takes a certain amount of desperation to drive most people to go through all the barriers and the stigma against heroin use. Just how society works I guess.
There is nothing about mortality rates in what you linked you drug addled dipshit.
Wow, you're really mad. Which part of taking a scientific approach to a major social and medical issue is it that pisses you off so much?
Technically you're right, I linked to fatality rates, and to the levels of exposure for alcohol and heroin. Do the math for yourself. If you want to include non-heroin opioids, use google. It's not hard dude.
