Reuters (11/2, Grens) reported that only about 4.5 percent of patients with chronic pain, who are prescribed opioid-based prescription medications, become addicted to the medication, according to a study published in the Oct. 18 issue of the journal Addiction. Researchers from the Cochrane Collaboration came to this conclusion after conducting a meta-analysis of 17 studies comprising more than 88,000 patients who were treated for non-cancer related chronic pain. Ten of the 17 studies provided the length of the treatment protocols, one of which was only a matter of days whereas the remaining nine ranged from three months to several years. Reuters pointed out that some experts questioned the whether the results are useful, considering the wide range of sources and treatment regimens.
