Users of pharmaceutical opioids are less likely to inject their narcotics, which is good for curbing infectious disease, but they are also more likely to mix them dangerously with cocaine, crack and other street drugs, the newly published study indicates. Meanwhile, experts are struggling to understand a supply system that includes retirees peddling painkiller prescriptions and pharmaceutical company employees selling purloined stock. With Canada one of the world's biggest medical consumers of opioids, which provide users with an anesthetizing release, the abundance of legal supplies has undoubtedly fed the illicit street market, researchers say. There is an "urgent need" to more closely investigate and comprehend the new opioid scene, says the study published this month in the journal Drug and Alcohol Review by researchers in B.C. and Toronto. "This is not a sideshow any more. In many communities, this is the predominant form of opioid, if not overall street drug, use," said Benedikt Fischer of the B.C. Centre for Addictions Research, the study's lead author. "These things are so abundantly available now, we are looking at multiple supply routes feeding this consumption. And these routes are a lot harder to define and grasp than heroin supply, which is very simple. "I don't think our enforcement system has in any way caught up to this or thought about how to cope with it properly." Overall, such stimulants as cocaine, crack and crystal meth are still considered the most common hard street drugs in Canada. The changes tracked by Dr. Fischer's group are among the significant minority who use opioids. Some of those users also take stimulants such as cocaine. Called OPICAN, the research project looked at about 480 opioid users in seven cities from Fredericton to Vancouver, in 2001 and 2005. They found heroin use overall dropped 24% in that period, while prescription opioid use jumped. By 2005, heroin had all but disappeared in four cities, although it was still common in Vancouver and Montreal, port towns with easier access to the imported narcotic. The paper published this month found that those using only prescription opioids -- 62% of the total -- were much less likely than heroin users to inject their drugs. About a third took the pills orally, while the rest would crush them into a solution they could feed into a hypodermic. The greater oral use could be good news on two fronts, since injection tends to increase the risk of overdose and, when needles are shared, makes transmission of HIV and other serious infections more likely, said Dr. Fischer. The study also found, though, that the prescription-opioid users were more likely to also use crack and other street drugs. The unpredictability of such mixing tends to lead to more overdoses, Dr. Fischer said. Supply appears to come from a variety of sources, he said. Some users obtain multiple prescriptions by visiting several physicians, a tactic called chronic "doctor shopping." Others buy from ordinary people who sell their prescriptions on the streets, including even senior citizens reported to do business at some Toronto bars, Dr. Fischer said. "No doctor would question a 70-year-old man who comes in [asking for an opioid] and says 'Oh, my back.' " But RaffiBalian, who runs the CounterFit harm-reduction program in Toronto, said he believes the bulk of prescription opioids on his city's streets are obtained through illegal means, such as thefts of pharmacies, sometimes by insiders. There is other evidence that the usual suspects are involved in the prescription opioid market. Project Rip, a major investigation into a Mafia-linked drug-trafficking ring in the Toronto area, prosecuted three New Brunswick Hells Angels members and others for trafficking in thousands of generic oxycodone and acetaminophen-codeine pills. A wiretap captured Constantine "Big Gus" Alevizos, a Mafia-connected dealer, discussing the purchase of one million Percocet-type tablets from the employee of an unnamed pharmaceutical company. Regardless of how users obtain the drugs, prescription opioids offer them some advantages over heroin, experts say. They are cheaper, more available and lack the unpredictability of heroin, which has sharply varying levels of purity. Rosemary Fayant, who was a heroin user in Edmonton almost two decades ago and is now head of a provincial drug-users' network, agreed that prescription pharmaceuticals have become the drug of choice for many addicts. She noted that some users will take them orally because "they don't have any [usable] veins left" after years of shooting up one drug or another. Not everyone buys the theory, however, that pharmaceuticals are pushing out heroin on Canadian streets, or that needle use is declining. Mr. Balian said prescription opioids became popular in Toronto as a way for users to soften the miserable crash following a stimulant high. Opioid addictions developed, but in many cases users wanted to move on to heroin, he said. "Three, four years ago, there were only a handful of heroin dealers here," said Mr. Balian. "Now, they're everywhere.... With opioids, what we are seeing is the number of injection-drug users are increasing." Nonetheless, Health Canada is concerned enough about abuse of opioids and other prescription drugs that it recently commissioned an Ontario expert to set up a system to monitor addiction to such medication. A few months ago, the department ordered a study of an even grimmer statistic -- the number of Canadians who overdose from prescription opioids. - --- MAP posted-by: Richard Lake
