TEN YEARS OF ABSTINENCE IN FORMER OPIATE ADDICTS: MEDICATION-FREE NON-PATIENTS COMPARED TO METHADONE MAINTENANCE PATIENTS

摘要

Fifty-five former opioid addicts who have been methadone maintained patients for 10 or more years and whose urine has tested negative for drugs for 2 or more years were compared to 99 former opioid addicts who have been medication-free for 10 or more years. Groups were comparable in age and education, but the medication-free subjects were younger when having started opioids with more severe addiction scores. Methadone maintained patients presented with a higher proportion of psychiatric comorbidity and chronic pain. Their scores of perceived sleep quality and cognitive state were poorer than the medication-free individuals. Possible explanations of the differences are discussed in this article.
