Huggins SOME REHAB PATIENTS USE ILLICIT DRUGS TO EASE PAIN NEW YORK (Reuters Health) - At least one in four people enrolled in substance abuse treatment programs may experience chronic severe pain, and many use illicit drugs to get relief, researchers reported Tuesday. In the study, 37 percent of participants in methadone maintenance treatment programs and 24 percent of inpatients in short-term, residential drug-treatment programs said they had suffered chronic severe pain. And among these, half of inpatients and one-third of those on methadone maintenance said they self-medicated with illicit drugs and alcohol. "Because patients are treated for addiction does not imply that their pain is being treated," study author Dr. Andrew Rosenblum of the New York-based National Development and Research Institutes, Inc. (NDRI) told Reuters Health. He noted that the study participants' pain was not related to withdrawal symptoms or any other aspects of their addiction. "They may have two disorders," Rosenblum said, "addiction and chronic pain, although each can complicate the other." In general, the prevalence of chronic pain among people with chemical dependency is "likely to be at least as high" as in the general population, the report indicates. Surveys have suggested that more than 70 million adults in the U.S. have chronic pain. "Pain is extremely common ... and it's devastating to an individual's quality of life," study co-author Dr. Russell K. Portenoy, of Beth Israel Medical Center in New York, told Reuters Health. "This is true also in people with addiction." Yet among the study participants -- who were most commonly receiving treatment for heroin, alcohol or cocaine use -- nearly half of inpatients and a third of those in the methadone maintenance programs were not receiving prescription medications for pain. The findings are published in the May 14th issue of the Journal of the American Medical Association. Most study participants said the chronic, severe pain interfered with their sleep, and many said it disrupted their work, mood and general activity. This indicates how "devastating the experience of chronic pain is for this population," Portenoy said. Patients in substance abuse treatment programs "are struggling to have pain adequately treated, just as others in our society are struggling to have pain treated appropriately," the researcher said. "It is likely," he added, "that their ability to access care is going to be more difficult than the general population because of their disease of addiction." Among inpatients with chronic severe pain, 35 percent said they had used alcohol to treat the pain, while 29 percent had used cocaine and 26 percent each had used opioids or marijuana. Thirty percent of those on methadone maintenance with chronic pain had used opioids for pain relief. The study included 390 participants in two New York methadone maintenance programs and 531 inpatients in short-term, residential treatment programs, also in New York. Up to 80 percent of patients in both groups said they had had some type of pain during the previous week. The study was funded by the Center for Drug Use and HIV Research and the National Institute on Drug Abuse. - --- MAP posted-by: Josh
